Practice creating bar graphs to represent data.
What is a bar graph?
Bar graphs show information about different categories. In a bar graph, the length of each bar represents a number.
Sara asked all the third graders at her school what their favorite pet is. Then she made a bar graph to show her results. Sara showed that
people chose cats by making a bar for Cat that lines up with .
Let's use Sara's bar graph to answer a few questions.
Practice Problem 1A
How many people chose fish?
Practice Problem 1B
Which pet was chosen most often?
Creating bar graphs from data
The Larson family has a pet mouse that snacks on apples, carrots, and cheese.
The images show the snacks the Larsons fed their mouse for one week.
Problem 2, Part A
How many apples did they feed their mouse during the week?
Problem 2, Part B
So what number will apples line up with on the bar graph?
Now that we know the Apple bar will line up with
we can drag the bar to on the graph. Then we can follow the same steps for the Carrot and Cheese bars.
Problem 2, Part C
Create a bar graph that shows the total number for each snack.
Creating bar graphs from tables
The Shen family is choosing a name for their new kitten. They ask their friends and family members to vote for a name.
|Name||Number of Votes|
Practice Problem 3
Create a bar graph to show how many votes each name got.

What label should the dog walker use for each bar on the bar graph?
Labeling the numbers
Ari is teaching his goldfish to do tricks. He kept track of the number of times his fish did each trick during the last week.
