# Lesson 16

Number Talk

### Lesson Purpose

The purpose of this lesson is for students to apply their understanding of dividing multi-digit whole numbers to create a Number Talk activity.

### Lesson Narrative

This lesson offers teachers the opportunity to listen to ways in which students make use of structure and repeated reasoning to design a Number Talk. After the warm-up, three activities are given, but it is not expected that students do all three. As the activities progress, there is one additional problem missing from each Number Talk. The choice of which activities to use is left to the teacher based on how much scaffolding the students may need. This lesson can take 1–2 days if students facilitate their creations with other groups.
