## Chapter 10

### Part 1: For the problem in the Teacher's Edition, page 232

Provide your students with a copy of the Activity page (PDF file).

Have students create a bar graph to show the information given in the circle graph on page 232. Students will need to have 5 bars on their graph and a scale that goes up to at least 27.

Next, suggest to students that they think of a question they would like to take a survey on. Have them survey as many people as they can and create a bar graph to show the results.

If you do not want your students to create their own survey, have them use the data from a survey on the data sheet to create a bar graph.

### Part 2: Be an Investigator

A good time to do this investigation is after Lesson 8 on using a graph.

#### Materials

- graph paper

#### Introducing the Investigation

Introduce the investigation by reading aloud the assignment at the top of the first page of the Description of Investigation and Student Report (PDF file), by having one of your students read aloud the assignment, or by having the students read the assignment individually.

Put students in groups of two to four to work on the investigation.

#### Doing the Investigation

Have students, who are having trouble deciding which kind of graph to use to display a set of data, look at Lesson 8 on pages 254-256.

**Answers:**

Answers will vary.

**Possible Answers:**

#### Student Report

The student report gives students an opportunity to show the graphs and plots they created and to tell why they chose each way of displaying data.

#### Extending the Investigation

Have your class collect data for a survey or sports event and then decide what kind of graph or plot would best show the data.
