Understand "equal groups of" as multiplication

EngageNY 60 min(s)

In this lesson, students begin understanding multiplication as the total number of objects in a number of equal-sized groups. They do a group counting activity and then work with counters to see the relationship between repeated addition, writing groups in unit form, and multiplication sentences. For example, they express 12 as 2 + 2 + 2 + 2 + 2 + 2, "6 twos," and 6 × 2. Finally, they write multiplication sentences to represent collections of objects, and determine when multiplication isn't appropriate to represent a situation.
