# Lesson 6 Choose a Scale

• Let’s choose a scale for our bar graph.

## Warm-up Notice and Wonder: Bar Graph Scales

What do you notice? What do you wonder?

## Activity 1 Represent Pattern Blocks

Here is a collection of pattern blocks.

Mai, Noah, and Priya want to make a bar graph to represent the number of triangles, squares, trapezoids, and hexagons in the collection.

• Mai says the scale of the bar graph should be 2.

• Noah says the scale of the bar graph should be 5.

• Priya says the scale of the bar graph should be 10.

1. Who do you agree with? Explain your reasoning.

2. Use the scale that you chose to create a scaled bar graph to represent the collection of pattern blocks.

## Activity 2 Represent More Data in a Scaled Bar Graph

All the third-grade students at school were asked, “What is your favorite time of the year?” Their responses are shown in this table:

favorite time of the year

number of students

winter

spring

summer

fall

Use the data from this table to create a scaled bar graph.

## Problem 1

The table shows the number of books some students have at home.

Use the information from the table to create a scaled bar graph.
