Give Struggling Students the Tools to Succeed!

All students can master pre-algebra concepts. Many students simply need to see the concepts presented in different ways. When students use Pre-Algebra Part 1 they enjoy it so much they do not consider learning math a chore. Many teachers report that their students think they are playing on the computer, but testing shows that they are actually learning math skills!

The following table is an outline of the interactive multimedia assignments in our pre-algebra part 1 programs -- Reporting and Web programs. The outline is organized by units. Each unit also includes a Pre- and Post-Test, depending on the program and has multiple assignments that include lessons, practice, learning tools and enrichment activities (Extras). Try an Activity: Each unit only has one sample assignment that is active – this is the assignment in red.
