This set contains foam blocks that can be used to visually demonstrate four basic algebra relations: (a + b) squared and cubed, and (a - b) squared and cubed. The set uses area and volume to represent terms that are the product of two and three quantities, respectively. Edge lengths are labeled in terms of a and b to help students relate the areas and volumes to terms in the above relations. Color instructions describe the use of the blocks to demonstrate these relations. Four reproducible worksheets guide students in the use of the blocks, including measuring and calculating areas and volumes to provide concrete demonstrations of these relations. Contains 12 blocks made from soft, durable, and nontoxic foam. Blocks measure 1" - 3" on a side. Grades 7-12.
