Grade 3 Mathematics Module 1, Topic D, Overview

Girl in Classroom

In Topic D students model, write and solve partitive and measurement division problems with 2 and 3 (3.OA.2).  Consistent skip-counting strategies and the continued use of array models are pathways for students to naturally relate multiplication and division.  Modeling advances as students use tape diagrams to represent multiplication and division.   A final lesson in this topic solidifies a growing understanding of the relationship between operations (3.OA.7).
