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.
