# Lesson 4

Multiplication Practice (optional)

### Lesson Purpose

The purpose of this lesson is for students to practice multiplication within 100.

### Lesson Narrative

In grade 3, students fluently multiplied and divided within 100, including recalling single-digit multiplication facts from memory. The purpose of this optional lesson is for students to practice multiplication within 100 and review strategies for finding products they don’t know.

Math Community

Before the lesson, explain to students that norms are expectations that help everyone in the room feel safe, comfortable, and productive doing math together. Tell students: “Some of these norms may apply to both you and me, however, there may be things you need me to do to support you in doing math each day.” Offer an example, such as: “It may help us share our ideas as a whole class if we have the norm ‘Listen as others share their ideas.’” Tell students you will pause at two different points of the lesson to identify norms that help everyone do math.
