### Lesson Purpose

The purpose of this lesson is for students to solve Compare, Difference Unknown story problems.

### Lesson Narrative

In this lesson, students practice solving Compare, Difference Unknown problems in which they are asked “how many more than” and “how many fewer than.” In the first activity, students solve problems in any way that makes sense to them. In the second activity, students are given information and asked to write questions that can be answered using the information. In both syntheses, students discuss how representing both quantities is helpful when solving Compare problems.

If students need additional support with the concepts in this lesson, refer back to Unit 2, Section C in the curriculum materials.
