This Problem Set is a part of the Lesson 16, Unit 1, Grade 3. 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 8 × 4 into (5 × 4) + (3 × 4) and draw an array to match. This lesson focuses on multiplication involving units of 4 in order to build fluency with those facts.
