Lesson 10
Multiplication and Division
Lesson Purpose
Lesson Narrative
In previous units, students learned the meaning of multiplication and division and understood division as an unknown-factor problem. They have worked to develop fluency with multiplication within 100. In this lesson, they continue that work by reinforcing their understanding of the relationship between multiplication and division.
In the first activity, students are given a card with an equation or a diagram and asked to find another student whose card represents the same situation or quantities. Then, they create an additional diagram and a situation that matches their division equation. Students then view and compare the diagrams and the situations that their classmates created in a gallery walk.
If students need additional support with the concepts in this lesson, refer back to Unit 4, Section B in the curriculum materials.
