Multiplication and Division Using Units up to 8

EngageNY

Description: Students are informally familiar with parentheses from having seen them in distributive property lessons in Topic B and in Module 1. In Lesson 8, they understand parentheses as tools for grouping and learn the conventional order for performing Grade 3 operations. In Lesson 9, students model and demonstrate how to multiplicatively compose or decompose to make problems using units up to 8 easier to solve. In Lesson 10, students use the 5 + n pattern as a strategy for solving multiplication and division problems using units of 8 with the distributive property. They learn that multiples of 8 can be thought of as (5 + 3) × n. In division problems, students practice decomposing the dividend using multiples of 5.
