Lesson 2: Bar graphs# Creating bar graphs

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 $30$ people chose cats by making a bar for Cat that lines up with $30$ .

Let's use Sara's bar graph to answer a few questions.

## 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.

Now that we know the Apple bar will line up with $9$ we can drag the bar to $9$ on the graph. Then we can follow the same steps for the Carrot and Cheese bars.

## 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 |
---|---|

Scooter | |

Fluffy | |

Whiskers | |

Jade |

## Labeling the bars

A dog walker kept track of the number of minutes he spent walking four different dogs last week.

Dog | Minutes spent walking |
---|---|

Buster | |

Charlie | |

Fluffy | |

Ginger |

## 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.

Trick | Number of times |
---|---|

Swim in circles | |

Blow bubbles | |

Swim backwards |

Ari made a bar graph to show the information but forgot to label the lines.
