Grade 3 Mathematics Module 4, Topic B, Overview

Girl in Classroom

In Topic B, students progress from using square tile manipulatives to drawing their own area models.  Anticipating the final structure of an array, they complete rows and columns in figures such as the example shown at the right.  Students connect their extensive work with rectangular arrays and multiplication to eventually discover the area formula for a rectangle, which is formally introduced in Grade 4 (3.MD.7a).
