Unit 9, Lesson 8
Solve Problems with Multiplication and Division
Grade 4
Preparation
Lesson Narrative
In the previous lesson, students solved word problems involving multiplicative comparison. In this lesson, they practice solving a wider variety of problems, with a focus on the relationships among multiple quantities in a situation. Students think about how to represent the relationships, with one or multiple equations and using multiple operations. They also interpret their solutions and the solutions of others in context, including interpreting remainders in situations that involve division (MP2). Students also have opportunities to make estimates and to assess their reasonableness when solving problems.
If students need additional support with the concepts in this lesson, refer back to Unit 6, Section D in the curriculum materials.
- Engagement
- MLR8
- Explain (orally) strategies for solving problems involving division and interpreting remainders.
- Justify (orally) that a solution to a problem involving division of whole numbers is reasonable.
- Let’s make sense of situations and solve word problems.

NoneTeacher Reflection Questions
What evidence do you have from their discussions that students used estimation strategies to make sense of problems and explain their thinking? How did students explain their estimates and how did they critique the estimates of others?
