# Lesson 2

Represent Data and Solve Problems

### Lesson Purpose

The purpose of this lesson is for students to solve one- and two-step problems about data represented in bar graphs.

### Lesson Narrative

Students solved one-step problems about data in grade 2. In this lesson, students first create a picture graph and bar graph that represent how they get home from school. Then, they solve one- and two- step “how many more” and “how many fewer” problems using data presented in a bar graph. Consider launching the lesson with a read-a-loud of Last Stop on Market Street by Matt de la Peña and Christian Robinson.

Math Community

Tell students they will have a chance to revise their math community ideas at the end of this lesson. As they work today they should think about actions that may be missing from the current list.

### Teacher Reflection Questions

Think about who participated in math class today. What assumptions are you making about those who did not participate? How can you leverage each of your students’ ideas to support them in being seen and heard in tomorrow’s math class?
