Unit 1, Lesson 18

Apply the distributive property to decompose units

EngageNY 60 min(s)

In this lesson, students use the distributive property to decompose new multiplication facts into the sum of two known facts (the "break apart and distribute" strategy). For example, they decompose 7 × 3 into (5 × 3) + (2 × 3) and draw a number bond to match. This lesson focuses largely on multiplication involving units of 3, 4, and 10 in order to build fluency with those facts.
