EngageNY 60 min(s)
In this lesson, students are presented with dots in varied configurations and break apart the total into two easily identifiable subsets. As students discuss the different parts they each see within the total and the different ways they are able to break the total apart, they begin to understand that a given quantity can be decomposed in a variety of ways. For example, 7 can be composed of a group of 3 and a group of 4 together, or of a group of 5 and a group of 2 together.
