Lesson Plan - Get It!

Being able to read information from a bar graph is an important skill!

Reading a graph allows us to understand large amounts of information in a quick and simple way.

Graphs are used in many areas of life, such as predicting weather, planning your own personal monthly budget, and even seeing who is in the lead of a race. There are many types of graphs, but today you are going to learn how to interpret information from a bar graph. You will also learn the different parts of a graph.

  1. Look at the Everglade Insects Bar Graph in Downloadable Resources in the right-hand sidebar.
  2. On a piece of paper, determine how many insects were located and graphed in the first two rows (top 2 insects on the graph). Explain how you arrived at your answer.

When we read a graph, we are able to see and understand information that is represented as data. However, we also need to learn about the different parts of a graph. They help us understand the data in the graph. Review the Camp Activities Bar Graph (Downloadable Resources) with all of the different parts labeled.

There are many questions we ask about the graphs we are trying to understand, or interpret. To become familiar with these questions, complete the Favorite Gifts Bar Graph (Downloadable Resources).

When you are done, continue on to the Got It? section for some more practice.
