Unit 1, Lesson 10# Model the distributive property with arrays to decompose units as a strategy to multiply

EngageNY 60 min(s)

In this lesson, students continue decomposing arrays in order to understand the distributive property. For example, they decompose a 3 × 6 array into 1 row of 6 and 2 rows of 6, and write the decomposition using parentheses: 3 × 6 = (1 × 6) + (2 × 6) = 18.
