Unit 4, Lesson 2
How Many in Each Group?
Grade 3
Preparation
Lesson Narrative
Previously, students solved “how many groups?” problems in a way that made sense to them. In this lesson, students extend problems involving sharing into equal groups to include “how many in each group?” problems. Students again have the flexibility to represent and solve problems using any strategy that makes sense to them in this lesson. If students use connecting cubes, encourage them to draw a picture to match their work. At the end of this lesson, division is defined as finding the number of groups or finding the size of each group when we share into groups of equal size.
- Engagement
- MLR7
- Compare and contrast (orally) strategies for solving “how many in each group?” word problems.
- Explain (using words or other representations) strategies for solving “how many in each group?” problems.
- Let’s represent and solve more problems.
Required Materials
Required Preparation
- Gather 2–3 posters from the previous lesson and this lesson that highlight counting the groups in a “how many groups?” problem and finding how many in each group in a “how many in each group?” problem.
Teacher Reflection Questions
What did you say, do, or ask during the Lesson Synthesis that helped students be clear on the learning of the day? How did understanding the Cool-down of the lesson before you started teaching today help you synthesize that learning?
