7th grade, Wed 12/16

Almost everyone finished their percent workshop. Many asked if they could have a catalog to take home -- I'll let them do this tomorrow. Hope I don't create any problems at home -- some of these items are very interesting (and expensive). Tomorrow we'll offer bonus points to any student who has their math portfolio ready.

Prealgebra, Wed, 12/16

Almost everyone finished their percent workshop. We'll finish up tomorrow by offering bonus points to those who get their math portfolio done.

Algebra, Wed 12/16

Students did turn in those second inequality packets today and received a final handout -- due tomorrow morning. One side says "get the message" and the other says "double whammy". These cover inequalities and equation solutions. We will have some in-class activities tomorrow that bridge from what we've been doing to what we'll be doing next.
The ASSIGNMENT -- finish the handout (both sides) -- and any XC items.

Algebra, Wed 12/16

7th grade, Monday 12/15

We continue to finish tests and work on the percent workshop. We'll finish these tomorrow.

Prealgebra, Tues, 12/15

A pleasant day today -- many students completed their percent worksheets. We'll finish tomorrow and/or start working on our portfolios.

Algebra, Tues, 12/15

Finally! Students got serious about those inequalities. There was much progress in class today. These 2nd packets on inequalities are due at the beginning of class tomorrow.

7th grade, Mon, Dec 14

Today many students spent time completing their computation tests.

Those that were done started working on a problem-solving workshop involving many percent calculations. They select items from catalogs for their own "store" -- calculate a discount price, then a markup price, then a commission. the goal is to get as close as possible to spending the $2500 our "money partner" is providing. This is all in-class work.

Tutoring this week is open to any student who would like to improve their grade.

Prealgebra, Mon 12/14

A few students needed to complete their tests but all the others are graded and entered in Powerschool. Students are spending Monday & Tuesday on a problem-solving workshop for which they form their own small business -- selecting items from catalogs, calculating a discount price then a markup price then a commission. The goal is to come as close as possible to spending all $2500 the "money partner" is providing.

tutoring this week is "open" -- any student who wants to improve their grade is welcome to come.

Algebra, Monday 12/14

Today and tomorrow we are spending time on a second problem-solving workshop packet for inequalities. This will improve the earlier grades on this item.

About those tests -- I'm not going to enter those grades -- they were just terrible.
We will take another look at linear equations and their graphs after break and try it again. I am disappointed but not really surprised -- this is the topic that each algebra class has had the most trouble with.

Math tutoring this week is open schedule -- anyone who wants to improve their grade is invited.

Prealgebra, thus, 12/10

Our test on computation was today -- a few students finished all of it -- most didn't. I'll allow part of class tomorrow to finish them. One extra credit assignment was available also. Next week we will have a chance to improve the test grade (if needed) and we will work on an interesting project.

Algebra, Thus 12/10

test today on linear equations and their graphs. I will allow students to spend PART of tomorrow on them (I collected them in class). The rest of our time until break will offer math work that can improve our grades -- two extra credit options were available today. Our primary focus will be on the inequalities (our most recent problem-solving workshop) and on test areas that need re-work.

7th grade, Wed - Friday, 12/9 through 12/11

forgot to blog yesterday -- we distributed study guides for the test -- test is on Friday
Thursday we reviewed these study guides, using the class votes as our priorities for topics to focus on. Friday is the test. Students may use their study guides / notes to help on the test. They may not use calculators for the first 3 pages, then they turn these in and pick up a calculator which they may use for the rest of the test. There will be a page of extra credit on the test. Next week we will have opportunities to improve our math grade, including our test grade.

Answers to the study guide follow and I will be at school early on Friday morning for any students who would like a last-minute study session.

7th grade, Tues, Dec 8

We finished with percents today -- we reviewed the 6-6 assignment where we worked with converting between decimals, fractions and percents and we learned how to calculate the percent increase or decrease between two quantities. The ASSIGNMENT is to complete just 8 items on the worksheet, Reteaching 6-8, #4,5,8,9,12,13,16 & 17.
Tomorrow we'll start to review all our computation topics and prepare for a test before the end of the week.

Prealgebra, Tues, 12/8

I handed out a study guide on the computation topics we've studied this quarter: integers, decimals, fractions, order of operations, ratios, proportions, and percents. It includes several examples of benchmark assessments, which are often used with high school students, so these 8th graders can start learning how to work with them. We will review the study guide tomorrow and we have a TEST ON THURSDAY. Students will be able to use the study guide to help with the test. During the first part of the test, students will not be able to use calculators. They will turn that part in and be able to use a calculator for the rest of the test. In the meantime, there is NO NEW ASSIGNMENT.

Algebra, Tues, 12/8

We finished working with parallel & perpendicular line equations today. I handed out a study guide for the TEST ON THURSDAY. We'll review tomorrow. There is NO NEW ASSIGNMENT. Students will be able to use their study guides to help with the test.

Prealgebra, Mon 12/7

We finished working with percents today -- completing our worksheet in class and reviewing the book assignment, too. There is no new ASSIGNMENT.
Tomorrow we'll start a review of all the computation topics we'd worked on this quarter
integers, decimals, fractions, percents, ratios, proportions.
We'll have a test -- most likely on Thursday.
Several students asked if we could do more Singapore math -- yes, it is in the works :)

Alg, Mon 12/7

What a chatty group today! Hope it isn't this way for the next 2 weeks.
We picked back up on transforming equations -- today we learned that:
if 2 lines are parallel, then their slopes are the same
if 2 lines are perpendicualr, then their slopes are negative reciprocals (they multiply to -1)
We are continuing to work with our handout on this -- the ASSIGNMENT is to complete items 17 - 23 for both parallel and perpendicuar lines (this is 8 items).
Tomorrow we will start to review for our test on this standard -- the test will probably be on Thursday.
Students seemed to have faulty memories about how long they had to work on the recent inequality problem-solving workshop packet. I reviewed my notes -- they were given out upon completion of the Relations & Functions test, Tuesday before Thanksgiving. We spent the next THREE ENTIRE CLASS DAYS on it not including the long weekend -- I provided some examples/answers to check on each of these days. I picked them up on the Wed following Thanksgiving break. Altogether, I provided answers in class to 28 of the 57 items.
Grades are down because of poor results (so far) on these packets. After our test this week -- we will re-open this topic and make improvements.

More on Prealgebra, Fri 12/4

Well, I guess it's been a long week. I just realized that, in fact, students didn't complete the assignment on percent increase & decrease in class so it IS the ASSIGNMENT for the weekend. Sorry for the mixup on the earlier posting. Grades in PowerSchool are up-to-date. I will have extra credit opportunities available next week.

7th grade, Friday 12/4

Yes !! today we finished our review of multiplying & dividing fractions with an in-class activity.
Students were reminded if they have any missing work. Extra credit work was offered. Otherwise, there is NO ASSIGNMENT over the weekend.

Next Monday we will discuss percents -- when we finish this we will start a review and be ready for a test on all our computation areas we've studied this quarter.

Prealgebra, Friday 12/4

We spent time on two activities today. One was an introduction to Singapore Math, presented by Mr. DuBree who has attended workshops on this interesting topic recently. The students in Singapore top all the international math competitions and it is very interesting to see how they learn math. We experimented with some of it today and I will continue to bring it into our class from time to time. It is especially good for learning/reviewing basic math facts -- which some of our students haven't yet mastered. Look for those triangular flash cards to make an appearance soon!

We also completed an assignment on percent increase and decrease. We didn't review the assignment from yesterday (also on percents) but we will review it in class on Monday. Then we will review all our computation skills from the entire quarter and get ready for a TEST -- probably on Thursday. There was NO NEW ASSIGNMENT over the weekend.

Algebra, Fri, 12/4

We finished off the last two items from yesterday -- graphing from standard form -- as a quiz.

Then we launched into transforming equations into standard form . We will continue with this on Monday -- we are almost done with linear equations & their graphs -- I hope to be ready for a test by the end of next week. There is NO ASSIGNMENT over the weekend.

I've started grading the inequality packets -- they'll get into powerschool before Monday. Many students had a tough time with this and we will be able to work on improving this grade before the end of the quarter but, in the meantime, I expect some grades will suffer.

All students who completed the functions retest saw their test score raise by at least one letter grade :)

7th grade, Thus 12/3

We spent about half the period updating our math folders.
Then we discussed/reviewed multiplying and dividing fractions, working several examples out as a whole class. There is NO ASSIGNMENT tonight.

Prealgebra, Thus, 12/3

We worked out of the book -- for the first time in ages -- and the overall class level of cooperation was the worst it's been in months. Unfortunately, this means we didn't complete our work in class so there is an ASSIGNMENT -- on percents -- in the book, Ch 6, Sect 6, items 4,8,12,16, 20, 25,26,27,28,29 and 30. I hope we get back to what has become a pleasant and successful class environment tomorrow.

Algebra, Thus, 12/3

Continuing on the topic of linear equations & their graphs -- today we reviewed our assignment and also discussed graphing from equations in standard form. We did several in class and I mentioned that I am planning to have the last two we didn't do serve as a quick quiz at the beginning of class tomorrow :) Then we'll switch to transforming equations.
there is NO ASSIGNMENT but students who wanted to improve their recent test grade need to turn in the re-test work tomorrow. It is items 1 - 7 on page 278 (end of Ch 5 in the book)
also there are a few who have not submitted their problem solving packet. I've entered info in Powerschool regarding which ones are turned in so far.

7th grade, Wed 12/2

We finished adding and subtracting mixed numbers today -- we reviewed the adding assignment and completed a dividing one in class. We discussed the concepts involved in multiplying and did a few examples but there is NO ASSIGNMENT tonight.

Prealgebra, 12/2

We reviewed dividing mixed numbers and had a quick quiz on it.
Then we started working with proportions -- in word problems and in similar figures.
THE ASSIGNMENT is to finish both sides of the proportion worksheet -- please write a proportion for each item and then solve it. This is just 16 items in all.

We also listened to some cool surfer music during class.

Algebra Tues 12/2

turned in those problem solving packets today -- I'm sure we are not done with this topic but I'll look them over and see what we need to focus on.

We got back into linear equations and their graphs -- starting with a review of slope and slope-intercept form. We did several examples in class and the ASSIGNMENT is to finish the few that we didn't complete -- on slope from graphs that's 13 & 15, on slope from 2 points it's 11, 13, & 15 and on slope-intercept form it's 2 - 6.

7th grade, Mon, Dec 1, 2009

We started by singing The Adding Song again. Then we reviewed yesterday's assignment on the board. Students did quite well and were asked to do 4 problems as a mini-quiz.

Then we started reviewing the yuckier items which involve adding fractions that are mixed numbers -- however, students said it's really not so bad :) We demonstrated several problems on the board and then got started on the ASSIGNMENT which is to complete the middle column on ReTeaching 4-4. This is six items: 2,5,8,11,14 and 17. Many students completed them in class.

Prealgebra, Dec 1, 2009

Sadly, I didn't receive any more of those mystery pictures today -- so those students will now see a zero on this key item in the gradebook :(

On a happier note -- we did well with our division of fractions assignment today. Only four students hadn't completed it before class and they were given a chance to "redeem" themselves by putting items on the board during our review.

We then discussed how to complete multiplication and division problems when the fractions are mixed numbers -- these require several steps:
1) change all mixed numbers into improper fractions
2) if a division problem, change it to a multiplication problem by using the reciprocal of the divisor.
3) multiply (numerator times numerator and denominator times denominator)
4) now see if the answer needs to be converted into a simpler form -- a mixed number or a simpler proper fraction -- this can be the hardest step

We completed several multiplication problems in class so the ASSIGNMENT is to complete the division problems in the middle column of ReTeaching 5-4. this is items 2,5,8,11,14,17 and 20. The first four just ask you to estimate the answer, the last three ask you to work it out completely.

Algebra, Dec 1, 2009

Today's the last day we spend time in class on the inequality problem-solving packet. I had selected answers on the board for all 5 sections so students could check their work and get help where needed. The packets are due at the beginning of class tomorrow.

We spent the last 15 minutes getting re-started on linear equations and their graphs. We will complete this topic and have a test on it before winter break.

Tutoring this afternoon focuses on the recent test over functions and relations. All students may attend but those with less than a C on the test must attend. Correct answers to all items will be discussed and then students will have a re-test opportunity.

7th grade, Mon, Nov 30

Back into adding and subtracting fractions -- this time with unlike denominators.
We sang the adding song which reminds us (to the tune of Freres Jacques)
What about fractions? What's their action?
Can we add? Is it bad?
Check denominators. Now instead of "later"
That's the rule -- keep your cool.
With an odd batch, when they don't match
Then convert -- just convert
One into the other, both into another
Keep it true -- good for you!

We practiced the left hand column on the handout (Reteach 4-3) in class -- THE ASSIGNMENT
is to conplete the middle column on this same page -- that's items 2,5,8,11,14,17,20 and 23.

I've written to Santa asking for Kleenex and dry erase markers. Hope I've been good.

Prealgebra, Mon, Nov 30

Back into fractions today -- multiplying and dividing them.

One group still needs to get me their thanksgiving dinner project by tomorrow. Eleven students still haven't turned in those mystery pictures.

I showed a model (rectangle) to use -- it's helpful to some but not to all.
Multiplying fractions is easy, though, just multiply the numerators (top times the top) and denominators (bottom times the bottom) then simplify.
Dividing is the opposite of multiplying so we just turn division problems into multiplication ones by taking the reciprocal (flip it) of the second number. So 1/2 divided by 3/4 is the same as 1/2 times 4/3.

Students did well in class -- the assignment is to finish itmes 13 - 30 on the handout (Reteach 5-3)

I have written to Santa asking for kleenex and dry erase markers. Hope I've been good.

Algebra, Mon, Nov 30

We continued working on the inequality problem-solving workshop packet today. I shared examples from the 2nd, 3rd, and 4th sections. Tomorrow I'll share examples from the 5th and final section -- these will be due to me on Wednesday.
Some students make good use of this time in-class -- they work in small groups and ask questions to make sure they are working correctly.
However, there are many students who take this working time as an excuse to socialize and basically goof off. I will not provide them with additional time to get work completed.

Tomorrow at tutoring I'll review all the answers to the recent test and show students what they can do to re-test/raise that test grade.

I have written to Santa asking for kleenex and dry erase markers. Hope I've been good enough.

7th grade, Wed 11/25

Prealgebra, Nov 25

Only one more mystery picture was ready to be turned in -- I have made extra copies for students who have lost theirs and I will accept them on Monday with only a slight deduction in points for being late. It would be a shame to not complete this assignment. Anyone who needs help with it should just ask or come for tutoring.

Our Thanksgiving Dinner problem-solving workshop -- focusing on computation -- was a success.
Only one team didn't complete their work and they were missing their materials with the 2 students who were absent -- they will have an extra day to complete it.

Some examples of the menus submitted are --

Test results -- mini-test on functions and relations:

A's 2 students (congrats to Ian & Chris)
B's 7 students
C's 4 students
D's 5 students
F's 5 students

PowerSchool is up to date.

The 10 students with D's or F's (grades lower than 20) on this test will need to attend tutoring next week to review this material and prepare for a re-test. Others who wish to do so may join them.

We will continue work on our inequalities & properties problem-solving workshop next week.

7th grade, Nov 23, 24 & 25

We are very involved in a Problem-Solving Workshop all this week.
The topic is Thanksgiving dinner and the tasks include developing a menu, using recipes to create a shopping list, and using grocery ads to determine prices. Students work in small groups and the project involves many computations, including with fractions and decimals. They have to think whether their results make sense. They are partial to desserts -- no surprise there.

Two groups have already completed their work -- here are their Menus:

One group is serving Chicken Anna, green beans, two-step cheesecake, pumpkin pie and double-delight peanut butter cookies. Their cost per person served is $7.54.

A second group is serving turkey and baby-back ribs, chitterlings, apple cider, pumpkin pie, ice cream, cake and cookies. Their cost per person is $8.11.

Prealgebra, Nov 23, 24 & 25

We are working on a Problem-Solving Workshop this week. The topic is Thanksgiving Dinner and students are working in small groups to develop a menu, ingredient list, shopping list, and prices. They are using real recipes and real grocery ads -- it's called an authentic assignment. The math topic is computation and the students are very engaged so far. As they get done, I'll publish some of their menus and prices (per person).

Oh my!!! Only six students have turned in those mystery pictures (graphing) that were due Monday. They are now late -- to avoid a zero in the gradebook (and this is going in as a test grade because of the size and complexity of the task) -- they need to get these done & to me. With only 3 weeks to go in this grading period, it would be a shame to lose this class' status as the middle school math class with the highest average grade :)

Algebra, Nov 23, 24 & 25

Yesterday we reviewed the topic of functions and relations -- today we had a mini-test on this smallest algebra standard. Two students need to complete this test tomorrow. There will be an opportunity to review & retest on this topic.

Following the test, students started on a Problem-Solving Workshop on the topic of inequalities using properties. The PSW will easily take all day Wed and also the Monday after Thanksgiving. We'll spend time in class working on it -- it is not homework.

After completing the work on inequalities, we will return to our work on linear equations and their graphs. We will have a test on linear equations and their graphs before winter break.

With the end of the grading period just 3 weeks away -- I am doing my best to keep PowerSchool updated every single day.

Reminder -- students are welcome to come for tutoring which is available 9 days out of 10 (every other Wednesday the math coaches and I have a committee meeting).

7th grade, Friday Nov 20

More on proportions today -- working on word problems this time.
We started with an interesting puzzle involving some pigs.
If not done in class, students need to finish over the weekend.
All next week we will be working on a Thanksgiving Dinner Problem-Solving Workshop.
There will be no homework unless there is missing work.

Prealgebra, Fri Nov 20

More success today working on the difficult topic of adding and subtracting fractions with unlike denominators. We also had time to work on those mystery pictures. If not done, they are due at the beginning of class Monday.

All next week we'll be working on a Thanksgiving Dinner problem solving workshop.
There will be no homework unless there is missing work.

Algebra, friday 11-20

today we reviewed the assignment from yesterday (on Practice 5-2) and learned two ways to determine if a relation is a function -- using mapping of the domain & range and by using the Vertical Line Test on a graph.
We also did a quiz -- which most completed in class but can finish at home if not done.
Monday we'll review the topic of relations & functions and Tuesday we'll have a mini-test on this smallest of Algebra standards.
Wednesday we'll have a problem solving workshop on inequalities.

7th grade, thursday 11/19

We did an interesting logic problem involving ice cream flavors, then reviewed proportions and practiced solving proportion problems. Almost everyone completed this in class -- so they have NO ASSIGNMENT.

We also got to sing the RATIO SONG (to the tune of Jingle Bells).

Students who hadn't completed (or done well) on the adding and subtracting fractions work from yesterday were given a chance to finish and/or correct their work.


Tomorrow, we'll try proportion story problems.

Prealgebra, Thus, 11/19

Today we tackled the hardest math skill there is -- adding and subtracting fractions with unlike denominators. I know this is something many students have not been able to master in the past so we took it very slow and made a lot of progress. Virtually everyone understood what the steps needed to be and could complete examples on their own. Yea!! We'll check tomorrow and see if everyone remembers what we did today.

There is NO ASSIGNMENT, but students should bring their mystery pictures to class and plan to finish them.

Algebra Thursday 11/19

We reviewed the assignment from Tuesday on function notation.

We finished covering new information on functions today by learning how to tell whether a relation is a function. We got to sing a song about it (Oh, domain and range . . .)

Tonights' ASSIGNMENT is on Practice 5-2, items 1,3,9,11,13,15,17,19, and 21

We have now covered everything in the function standard (it's the shortest one) and will have a mini-test next Monday or Tuesday.

7th grade, Wed, 11/18

We worked on fractions in several ways:
students took turns on line at www.shodor.org trying fraction-based activities
students completed two simple worksheets on adding and subtracting fractions with like denominators
there were other hands-on fraction activities that used different shaped tiles, tangrams, or fraction model pieces
NO ASSIGNMENT

7th grade, tues, Nov 17

we spent time in class finishing the ratios & proportions assignment before checking the answers. when done, we spent some time reviewing some fun critical thinking puzzles (thanks to Elmo). then we finished by completing a short quiz on ratios & proportions.
There was an XC ASSIGNMENT available on proportions & equivalent fractions, Puzzles 6 & 29.

Prealgebra, Tues Nov 17

Still doing a great job with fractions -- today we covered subtracting fractions and mixed numbers with the same denominators. Students had time to work on their mystery pictures -- which are due Friday. There is no assignment -- it was completed in class.
Tomorrow we will miss class because of our field trip.

Alg Tues, Nov 17

More on functions -- we reviewed the assignment and worked, in teams if desired, on analyzing 8 graphs. We also discussed function notation, domain and range. There is a small ASSIGNMENT, on the ReTeach 5-2 page, just items 6,8,10,13, and 15.

tomorrow we will only meet for 1/2 hour before our field trip. We'll field any questions and get that assignment completed/reviewed before we go. There will be no new assignment tomorrow.

7th grade, Mon, Nov 16

we started with a maze based on multiples of three.
Then into fractions by way of ratios and proportions.
We reviewed in class and the ASSIGNMENT is the even items on the handout (both sides) labeled 6.2 & 6.3.
A few students got a turn exploring interesting fraction activities on one of two websites (all students will get a turn over the next several days): www.shodor.org and www.nctm.org

Prealgebra, Mon Nov 16

WOW! this class has the highest class average ( B) and no student has a failing grade. I made a deal with them - if we have all C's and above at the end of the quarter -- it's a popcorn party in class.

We are making excellent progress on our fraction unit -- today we worked on adding fractions and mixed numbers with the same denominators. Everyone said this was very easy. We also reviewed how to calculate multiples of three in a warm-up activity and THE ASSIGNMENT is to complete Puzzle 29, applications of proportions (just this one side, please).

Reminder, those mystery pictures, plotted on graph paper, are due by Friday.

Algebra monday 11/16

We are taking a couple of day's break from linear equations to cover the topic of relations and functions. This is found in Chapter 5, sections 1 & 2 of the textbook. Today we discussed interpreting a graph, creating a sketch of an event (or a story) and analyzing graphs. There was excellent participation in class. The ASSIGNMENT is to complete the items on the handout: Practice 5 - 1.

7th grade, Friday Nov 13

We explored fractions some more -- taking turns creating drawings of equivalent fractions -- then solving some proportions and reducing to simplest form.
We ended by touring some very interesting fraction activities on line
my two favorite websites for these are www.shodor.org and www.nctm.org but there are many more. Students will be able to take turns spending time on them during classes next week.
NO ASSIGNMENT this weekend.

Prealgebra, Fri, Nov 13

We looked at actual examples of unit rates which we calculated from advertisements.
Keep bringing in those Thanksgiving recipes!!
We also had a Friday the thirteenth good luck fraction quiz -- and 13 of the 20 students here today earned an A on it.
NO ASSIGNMENT over the weekend -- but students did select their mystery picture to work on -- it is due next Friday.

Algebra, Friday 11/13

We reviewed standard form, turned in the assignment from 2 days ago and then had a quiz on slope-intercept form. there is NO ASSIGNMENT
students who didn't do well on the quiz are scheduled for tutoring next Tuesday, 3:20 - 4:00

7th grade, Wed 11/11

Finally, we did finish our last decimal assignment (the palm tree picture worksheet) -- almost everyone got it done in class. If not, it's due Thursday.
We started talking about our next unit -- on fractions.
I asked students to write the answers to two questions as an ASSIGNMENT:
1) if you have not succeeded with fractions in the past, why do you think you have been unsuccessful? and
2) what are you willling to do to succeed with them this time?
I told students that I am planning to use new and different teaching methods with them to help them "get it".
Still looking for their recipe of their favorite Thanksgiving dish -- I've only gotten a handful.
Many students will be on the band field trip Thursday so we'll not have an assignment but will focus on hands-on fraction activities.

Prealgebra, Wed 11/11

we spend a day in the computer lab working with fractions on one of two websites: www.shodor.org or www.nctm.org. Each student had a list of the specific activities to try.
Because of the band field trip Thursday, we will practice converting from improper fractions to mixed numbers and back again -- There is a page on this in the skills workbook section in the back of the textbook. This should get done in class so that there is no homework.
This class is justifiably proud of their grades -- they have the highest class average of all 7th and 8th grade math classes -- no one is failing. Keep up the good work!!

Algebra Wed 11/11

Reviewing those properties was needed -- some got it, most needed help with it.
Then, back to linear equations in standard form and transforming equations.
We did some examples in-class and
The ASSIGNMENT is to try items 21 - 24 and 29 - 32 on Practice 6-3

Thursday, many students will be on the band field trip -- we will not cover new material but will practice calculating the x- and y- intercepts from standard form equations and then practice plotting the line. There will be no homework.

7th grade, Tuesday, Nov 10

We started with an interesting problem -- solved two parts and the other two are bonus points if solved this week. These are:
1) how many different ways are there to make 53 cents in change (e.g. one way is 53 pennies)?
2) if you purchased an item that costs $2.99 plus 6% tax and paid with a $20.00 bill, what would be the minimum number of coins the cashier could give you as change?

Today we did finish our dividing with decimals task -- those who did a good job on it yesterday earned 10 points and started the final decimal assignment (which reviews all decimal operations). Those who did a good job on today's in-class assignment earned 9 points and have no homework assignment. Those few who didn't complete it well enough yesterday or today were given additional practice items to complete as homework. Their top grade will be 8 points, if all are completed correctly when turned in tomorrow.

Prealgebra, Tues, Nov 10

We started by reviewing three decimal division problems.
Next we checked our assignment on ratios and unit rates -- students did so well we had a quick 4 item quiz and only a few students will need to do further review on this topic.
We shared some real-life examples of unit rates from grocery store ads so that students know why this is useful information.
Finally, we did an algebra activity that involves plotting points and connecting them to create a picture. This is a very important basic algebra skill -- and making it into a picture made it interesting. There will be a similar assignment with a more challenging set of instructions later this week.
Tomorrow we head to the computer lab to practice working with fractions. There is no homework today or tomorrow!!

Algebra, Tues, Nov 10

We started by reviewing 3 division problems with decimals -- and some of us had forgotten how to do these.
Next we checked yesterday's assignment -- students did very well on this topic (slope-intercept form of a linear equation and its graph) they should be ready for a quiz sometime soon

We introduced the standard form of a linear equation and practiced finding the x- intercept and y-intercept and graphing it from the equation.

The ASSIGNMENT is both sides of a handout that reviews the three most important properties: distributive, associative and commutative. The earned a collective groan from the class so I'm sure it's needed!!

7th grade, Mon Nov 9

wanted to finish dividing with decimals today -- didn't get that accomplished. There were five problems to complete and almost no one did. Really? Since it seems our skills are so weak on this skill -- guess I'll have to continue with it, including with some tougher problems -- cause when I checked with my standards (and their previous teachers), they should be able to do this without all the complaints and "it's too hard"s.
Those five problems (which must be completed before class tomorrow) are:
1) 80.19 divided by 9.9
2) 167.4 divided by .93
3) 8.36 divided by 1.9
4) 225 divided by .45
5) .3086 divided by .66

Prealgebra, Mon, Nov 9

four students had their favorite Thanksgiving dish recipe today
We worked from the book, Ch 6, on ratios & proportions -- today was ratios & unit rates
the ASSIGNMENT: ch 6, sec 1 (either page 290 or 294) items 1-16.

Algebra, Monday Nov 9

for a warm-up activity we practiced addition & subtraction with integers
then we got back to graphing from slope-intercept form equations and writing the equation from the graph.
the ASSIGNMENT: on the handout -- Practice 6-2: 9,12,15,18,21,24,31-36 & 39-42

all classes, Friday Nov 6

No homework this weekend
except that prealgebra & 7th graders need to find a recipe for their favorite Thanksgiving dish and bring it to class. We'll be using this for a project on fractions.

7th grade, thus nov 5

we sorted our sketch examples into three categories: too hard, too easy, or just right.
Today was the one day I requested students to try multiplying using the lattice method -- they needed to complete 5 items (including decimal point placement). there is no homework.

prealgebra, thursday nov 5

this was my favorite day in this class for the entire year!!!
We started by drawing a fraction. We shared our drawings -- (one student, KH, had an outstanding linkage of examples to share).
We discussed: who used fractions, what kind of fractions are there, what are the parts of a fraction
finally THE ASSIGNMENT is to complete the even items in the skills handbook section of the text -- which is either p. 771, or 793, or 809 depending on the edition you have.
By student request -- there were also 5 challenging compound fraction problems on the board -- these will be extra credit.

Algebra, thus, Nov 5

Great day in algebra class today -- everyone had done the assignment and done well on it.
We reviewed it and then we found creative ways to act out slope.
finally, we reviewed slope-intercept form (the back side of yesterday's assignment) --
Practice 6-2 the NEW ASSIGNMENT is to find the slope and intercept of items 5 - 24.
Actual graphing of these will happen in class tomorrow.

7th grade, nov 3

we discussed the assignment that reviewed key number sense topics (credit for effort in powerschool)
There was a quiz on multiplying and dividing decimals by powers of ten (notes and previous assingments could be used to help)
We will continue to work with decimals & multiplying and dividing them -- I will insist that we spend one day doing multiplication by the lattice method (tomorrow). After that, students may use any method they like.
some students in the core 3 class (Ms. Jacob's homeroom) had seen the blog and knew the secret to getting a bonus point on the quiz. no one in my homeroom did.

prealgebra, wed nov 4

We had some time to continue to work on our final decimal assignment (hidden picture) today. I will still accept it tomorrow and not count it late (but that's the last day).
We also updated our folders with all our work on decimals this quarter.
We have a new seating chart which we will use while we work on fractions -- our new topic.
I spent considerable time reminding students:
they have done a good job this quarter paying attention and trying -- the grades show it
they can also do this with fractions
research (and my own experience) shows that learning fractions is the best thing you can do to prepare for success with algebra in high school
we will continue to do most of our work together in class which will help them succeed
we will also use some other learning methods (on-line and building models) to help them fill in any learning-gaps with fractions
all of these students can improve their skills with fractions
THE ASSIGNMENT tonight -- think about these two questions and write down your answers:
1) what has kept me from being successful with fractions in the past
2) what am I willing to do this time in order to be successful with fractions
I'm going to be very interested to read these!!

Algebra, Wed, Nov 4

We are getting pretty good working with those equation "transformers" -- a tricky skill. We reviewed the even items on ASG p 56 and we turned in our revisited take home quiz (from last Thursday).
I provided a "preview of coming attractions" on the standard form of linear equations -- we then looked at a list and identified which ones were and weren't in this form.
Finally, students received a worksheet that reviews our work on slope (on one side) and slope-intercept form (on the other). We worked one of each of four types on the first side and
THE ASSIGNMENT is to finish this side -- Practice 6-1.
Slope is rise over run, slope is how the y's change over how the x's change, it's the rate of change -- the more ways we know to think about it and calculate it, the better.

7th grade, Nov 3

today we finished dividing decimals by powers of ten.

There is an assignment tonight -- a handout I prepared that reviews some key number sense topics.

Students don't know it, but we'll have a quiz tomorrow covering multiplying and dividing by powers of ten. Those who have read this blog should write the code phrase "I'm one" under their name on the quiz and get a bonus point.

prealgebra, tues Nov 3

today we wrapped up our unit on decimals. Students are finishing an assignment that includes 15 items. they must do them on separate paper and show their work. then they write the answers on the handout and use the clues at the top of the paper to see what needs to be colored in.
Effort in class has been quite good this quarter and the grades are strong. Many students have the highest grade they've ever had in a math class -- I hope we can hold onto that motivation as we take up our

Next topic -- fractions!!

Algebra on tuesday Nov 3

We started with three items on domain & range. Domain is the "x" and range is the "y".
Next we tackled those tough transformer equations. I think we made a great deal of progress on this in class today. We reviewed the assignment (full credit was taken for effort).

Tonight, students need to look at the rest of the transformer equations -- ASG, p. 56, the even ones we haven't already done.

They also need to do or look over the take home quiz items that were assigned last thursday but only 7 students had attempted. Those are in the algebra book, p 288, 54 - 62. Only those who tried them on time will get the maximum credit, but all others can certainly get better than a zero.

7th grade, monday nov 2

we continue to work with decimals -- today's focus was on dividing decimals by powers of ten.
Students did very well. We may get done with decimals this week!
There is no homework unless a student has missing work.

Prealgebra Monday Nov 2

today we continued our review of long division with decimals. Students needed to complete five problems correctly in 40 minutes. There were 12 who did this. Yay!! The other 7, who did not, need to complete the middle column (6 items) on the handout -- clearly they need some extra practice. (They are also most welcome to come for tutoring after school, too.) I think some who have never really been able to do long division may have made some key progress.
We started class with a review of some key number sense items, divisibility rules, factoring, and identifying rational numbers.
Finally, we continue to talk about good habits of mind -- those that help us succeed.

Algebra on Monday Nov 2

Today in class we started with a review sheet on number sense -- divisibility and factoring and rational numbers.
Then we learned how to transform equations -- the assignment for tonight is to complete the odd items (3 - 19) on p. 56 of the Algebra Survival Guide. This must be done on a separate sheet of paper so you can show the work. It is only 9 items, just like those we did in class today.
Due today was a Take Home Quiz, from the book, page 588, items 54-62. Only 7 students had anything to turn in (it was assigned on Thursday). This is not acceptable. Those who didn't even try it need to "get 'er done".

7th grade thus, Oct 29

today we finished our review of multiplying decimals by all powers of ten.
no homework other than finishing the habits of mind self-check and any missing work

prealgebra, thursday oct 29

today we practiced our long division -- using decimals.
From the response of the students, it is clear that this review is needed.
We will continue on this topic Monday but will take a break tomorrow and have a problem-solving workshop activity.
There is no homework but any missing work is now overdue.

Algebra, thus oct 29

reviewed what we'd been learning all week about slope and the slope-intercept form of that linear equation.
the assignment today was, again, scored on effort -- those who hadn't done it before class earned 1/2 credit by completing it during our review.
I haven't received any other late assignments this week.

The assignment is a THQ (take-home-quiz) -- items 54 - 62 on page 258 of the textbook --
this is due on Monday because we have a problem-solving workshop tomorrow.

7th grade on Wed, Oct 28

both classes successfully completed our review of adding and subtracting decimals today.
no homework -- we are completing our work in class.
any extra credit or missing assignments must be turned in tomorrow (thursday).

prealgebra, Wednesday

continuing our work on decimals -- students had to demonstrate mastery of multiplication of decimals without using a calculator. This is an important basic math skill and students are showing they can put in the effort to succeed. This class has the best grade average so far this quarter!!

Algebra wednesday

Are we graphing !! today we reviewed what we'd learned yesterday and added: finding the x- intercept and y-intercept by looking at the graph and we learned how to identify slope and intercept from an equation that is in slope-intercept form (boy is this easy -- so easy students miss it because they try to make it harder than it is)
the assignment is to finish page 54 from ASG (that's the Algebra Survival Guide) -- the handout we've been working with in class.
again -- grades for the assignment due today are based on effort -- zeros indicate no effort. these can be made up (for 1/2 credit) by doing the assignment tonight and getting it to me tomorrow.

7th grade, tuesday

we switched from working with integers to working with decimals today
this means we formed new groups and we updated our folders for the first time this quarter
students need to get missing and/or extra credit work on integers to me by Thursday.

prealgebra, tuesday

moving forward with more work with decimals -- today we finished dividing by any power of 10
we moved into multiplying decimals that are not just powers of ten.
I insist that all students develop skill with multiplying using the lattice method -- ask to see it at home :)
no homework -- everyone needs to get any missing or extra credit work to me by Thursday

Algebra on tuesday

we checked the answers on yesterday's assignment, but the gradebook only shows full credit for trying this assignment -- zeros mean the student just didn't do it (but can receive half credit for trying it tonight)
in class we worked with our individual dry erase graph boards and learned how to calculate slope if we are given two points by graphing and without graphing (a slightly tricky calculation)
we also learned how to graph a line if we are given one point and its slope
tonight's assignment, chapter 6, section 1 (again), page 287 - 288, items 28 - 44 (just evens)

7th graders on Mon, Oct 26

this is our final day focusing on integers. We had one review sheet on adding integers (the key to it all) for everyone to complete -- it is called Puzzle 39.
There are two extra credit options: Puzzle 10 (on the back of Puzzle 39) and/or finish your integer brochure.
I also let each student know about any missing work -- it must be completed this week to avoid a zero in the gradebook.
Tomorrow -- on to decimals!!

prealgebra assignment - monday 10/26

on the handout covering dividing decimals by powers of ten -- the 0.1, 0.01, & 0.001 side
the entire right hand column is homework

we also let individual students know about any missing work -- it is due by Friday or will be scored as a zero.

students were reminded that extra help is available from 3:20 - 4:00

Algebra - monday's assignment

in the textbook, chapter 6, section 1, page 286 & 287, the even items 2 - 24 -- all about SLOPE!

7th grade on Friday

Today we reviewed our work with integers and had a very low-key quiz.
We should finish with integers on Monday -- then on to decimals!

Friday in algebra

Well -- these absences are destroying my lesson plans this week -- there were 5 students out today -- 5 yesterday, 3 wednesday, 4 tuesday, 5 monday.
I let the students have today to continue to work on our function lab notes and quiz and our problem solving workshop handout. On the bright side -- it has been a good way for students to review basic equation solving skills and gain an overall understanding of function families :)
Those who haven't completed them today need to find time between 3:20 & 4:00 to get caught up.
We will be moving on to new material next week!!
grades will be up-to-date by Monday -- you will be able to check powerschool to see what is still missing.

7th grade thursday, oct 22

we spent time in class working on more complicated problems -- adding, subtracting, multiplying and dividing integers which requires students to "shift gears" in order to get the correct answer each time.
then we did some work on mixed operations problems - do you have an Aunt Sally? to get these correct you need to "please excuse my dear aunt sally".
I think it's time for a couple of quick quizzes on these integer operations tomorrow (we'll review first).
Parents: by this time, students know if they "get it" or not -- if not, they need to be encouraged to come for some extra help from 3:20 - 4:00. We will not just trust them to make this decision -- some will be told they need to come in.

Prealgebra class -- decimal secrets revealed!

One team won the prize (special pencils) from our warm-up!!
Students shared the secrets of working with decimals:
for adding and subtracting, here they are (in the order you need to use them):
1. make it an up & down problem, not sideways
2. line up the decimals, including in the answer
3. add zeros if you need them to make the numbers line up
4. keep the decimal point in the same place, don't move it
5. work from right to left (in other words, from the smallest place value to the greatest)

then students practiced adding and subtracting until they could get 5 items in a row correct -- almost everyone did it on the very first try!

We ended up by sharing secrets for multiplying -- they are different than adding & subtracting:
1. make it an up & down problem (instead of sideways)
2. the decimals don't move in the numbers you start with, but it does move in the answer
3. work from right to left
we are starting to refine these secrets by multiplying by 10, 100 and 1000 -- we'll continue tomorrow.
No homework -- we are doing a very good job during class and don't need it!

Algebra class today

We still have many students out -- but we forge ahead. Today students worked with the quiz on function families -- others turned in their notes on this topic -- and most have completed (or almost completed) their problem-solving workshop packets. We will review and finish all of these tasks tomorrow in class -- any of them not completed by then will mean a student should plan to come for one-on-one help after school (3:20 - 4:00)

7th grade classes

Welcome to the blog!! I'm learning as I go -- check back frequently to see what I've learned.

This quarter, our work focuses on computation and algebra skills and concepts. We started by having each student complete a basic skills check so that our approach can be individualized.
Based on these results, each class was divided into small groups focusing on our first topic -- integers (those positive and negative numbers). Most students like working in small groups and having a student who is already good at a topic volunteer to serve as leader helps them reinforce and expand their knowledge, too. So far, we have covered adding, subtracting, multiplying and dividing with integers. We have had in-class and homework assignments and today (Wednesday, Oct 21) will spend time reviewing what we know how to do and preparing a brochure with the rules and examples of each.

Note to parents: There have been many absences and I have adjusted the lessons accordingly -- we spend multiple days on a topic and I accept late work and/or substitutes for the original assignment. PowerSchool is up-to-date and there are many blanks. If you are concerned, please check with me on an individual basis -- it may be a good idea to have a student come for some special catch-up time after school (3:20 - 4:00). This is available virtually every day. My direct email is crichardson@ics-charter.org

8th grade, Pre-algebra class

Welcome to the blog!! I'm learning as I go. Check back frequently to track my progress.

Second quarter we focus on computation and algebra skills. We have started with a basic skills check to see what students are already good at. Our first topic was integers (positive and negative numbers) and we have worked in small groups on several assignments -- adding, subtracting, multiplying, dividing and doing combinations of these in the same problem . The final assignment asked students to create a small brochure summarizing the rules they use along with two examples for each of these tasks.

Note to parents: All the completed work on the integer unit has been graded and entered in PowerSchool -- students have been informed about any missing work and have been told what they should now do to substitute for missing items. If they need extra help -- tutoring is available virtually every day from 3:20 - 4:00

We have just formed our new small groups which will start working tomorrow (Thursday, Oct 22) -- the new topic is decimals.

8th grade, Algebra I class

Welcome to the blog!! I'm learning as I go -- first I'll include what we have been doing this Quarter. Later, I'll learn how to add links to useful websites, ways to interact, interesting problems (for bonus points), etc.

This quarter, Algebra class focuses on the standards concerning solving equations and inequalities, linear equations and graphing. This information builds on what students have done in earlier years, so should not be as "weird" as some of the math last quarter. That also means that grades should be as high or higher !!

During the first week, we visited a website (www.Shodor.org) and explored the function machine activity. We also spent several days investigating different types of functions: radical, cubic, quadratic and linear -- we graphed them by hand and using a graphing calculator (free on line and my personal one in class). We debriefed our information and made notes about the characteristics of each function family.

It is now Wed, Oct 21, and we have spent 2 days in a problem solving workshop that is covering some basic equation-solving skills (so we have a good starting point on this critical topic).

What about grades?
the function lab grade is worth a total of 20 points -- everyone did a nice job of working on this and has earned 10 of these points. The other 10 are based on the quality of their notes (from our debriefing session). So far, 13 students have shown me their notes so they have a grade. Everyone else needs to show me their notes by the end of class tomorrow.
We will have a quiz on the function families (notes may be used!) before the end of this week.

The problem solving workshop will be graded in two parts -- the first involved completing a series of math puzzles and is worth 70 total points; the second is a "chapter 1 test" from another good algebra book I like to use -- worth a total of 25 points. These will be scored and entered before next Monday.

Note to parents: we have been having more than the usual amount of absences and I have altered my lesson plans accordingly -- students have longer to work on items and we spend more time in class on them. However, if they are slipping, they may need to come for some extra help to catch up -- tutoring is available almost every day from 3:20 - 4:00.
