Book 1 introduces students to algebraic ways of using the distributive property at three levels: manipulative, representational, and abstract. Algebraic multiplication differs significantly from the arithmetic algorithm so students must learn new processes. Activities help build mental imagery of algebraic processes and reinforce concepts by using parallel manipulative, representational, and abstract approaches. Begines with learning new concepts and processes in the familiar base ten environment, followed by applying parallel approaches using base 3, 4, and 5 numbers, and finally transitioning to algebra by translating the same processes to similar literal equations. | |
