# Lesson 7

### Lesson Purpose

The purpose of this lesson is for students to draw a scaled bar graph to represent a data set with several categories.

### Lesson Narrative

In a previous lesson, students used a survey to collect data. In this lesson, they represent their data set with a scaled bar graph. Then, students ask and answer questions about the information presented in their scaled bar graphs.

If students need additional support with the concepts in this lesson, refer back to Unit 1, Section A in the curriculum materials.

• MLR8

### Learning Goals

Teacher Facing

• Draw a scaled bar graph to represent a data set with several categories.
• Solve one- and two-step “how many more” and “how many less” problems using information presented in scaled bar graphs.

### Student Facing

• Let’s represent our data on scaled bar graphs and answer questions about the data.

### Required Materials

Materials to Gather

Materials to Copy

• Draw Scaled Graphs

### Required Preparation

Activity 1:

• Each group of 4 needs the survey data from the previous lesson.

Activity 2:

• Each group needs the bar graphs they created in the previous activity.

### Teacher Reflection Questions

As students worked in their small groups today, whose ideas were heard, valued, and accepted? How can you adjust the group structure tomorrow to ensure each student’s ideas are a part of the collective learning?
