Grade 3 Mathematics Module 1, Topic E, Overview

Girl in Classroom

Topic E shifts students from simple understanding to analyzing the relationship between multiplication and division.  Practice of both operations is combined—this time using units of 4—and a lesson is explicitly dedicated to modeling the connection between them (3.OA.7).  Skip-counting, the distributive property, arrays, number bonds and tape diagrams are tools for both operations (3.OA.1, 3.OA.2, 3.OA.9).  A final lesson invites students to explore their work with arrays and related facts through the lens of the commutative property as it relates to multiplication (3.OA.5).
