PRODUCT DESCRIPTION

This resource is an excellent way for students to learn to analyze data in a circle graph. They start off by identifying the three types of information that can be given to them, or that they can be asked to find:
1.) Percents
2.) Central angle measure
3.) Number of pieces of data in that section

I have used this activity with 7th and 8th graders to help build their understanding of proportional reasoning by teaching them to set up a proportion to solve each problem. They also build on their understanding of percents, angle measures, and obviously circle graphs.

After this lesson, I have my students collect their own data, and create their own circle graph by calculating the percents and central angles, then using a protractor to measure out the appropriate angles.
