Prealgebra, Wed, 12/9

we reviewed our study in preparation for tomorrow's test. Students may use the study guide to help them on the test. The first part of the test will be with NO calculators. When that part is turned in, students may use calculators for the rest. There will be a before-school study session in my room -- anyone is welcome to come and participate.
