Title Apples in Baskets - Decomposition of 2 addends
Description Students find ways to put 8 apples in two baskets. This lesson highlights how the number 8 can be decomposed in multiple ways, allowing for students to see how the addends change (as one increases by 1, the other decreases by 1). If desired, this lesson could also help students see the commutative property in action as the addends can be changed and positioned in different locations in the play area.
