Unit 1, Lesson 19

Apply the distributive property to decompose units

EngageNY 60 min(s)

In this lesson, students use the distributive property as a strategy for division. Similar to the way they used the distributive property for multiplication, they decompose a new division fact into the sum of two known facts. For example, they decompose 24 ÷ 2 into (20 ÷ 2) + (4 ÷ 2) and draw an array to match. This lesson focuses largely on multiplication involving units of 2, 3, and 4 in order to build fluency with those facts.
