Students will take a Chapter 2 pre-test. Based on their performance on the pre-test, areas will be identified that are strengths and areas that need additional review. Students will work in groups at centers to learn the concepts. Each center is based upon one of the sections in the book. The centers include notes, practice problems, group discussion, and individual homework problems. If students finish the centers before the test, they will then have the opportunity to work on a math project.
