This Problem Set is a part of the Lesson 19, Unit 1, Grade 3. 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.
