Unit 4, Lesson 22

Solve additions with up to four addends with totals within 200 with and without two compositions of larger units

EngageNY 60 min(s)

In this lesson, students apply the associative property to add up to four two-digit addends with totals within 200. They use the associative property, to add numbers in an order that is easiest to compute, for example, when solving 24 + 36 + 55, a student adding ones may make a ten first with 4 and 6.
