Math Project: How to Make Circle Graphs and Pie Charts

This fun math project includes clear step-by-step instructions to show your students how to make a circle graph. This is a great way to review several math skills while showing how useful they can be!

Tasks include:

- Writing a survey question: Your students learn to write a question that has exactly six possible answers.

- Collecting data: Your students can ask the members of your class their question. They collect data using a tally chart. They need to ask exactly 25 people.

- Recording results as a fraction: Once they have their data, they can turn each answer into a fraction with a denominator of 25.

- Calculating an equivalent fraction: Then, they calculate an equivalent fraction with a denominator of 100.

- Working with percent (written as a decimal): Finally, they turn that fraction into a percent in decimal form. They use this percent to multiply by 360 degrees in a circle (they can use a calculator for this part) to find out how many degrees each answer gets.

- Drawing angles with a protractor: They carefully draw the six angles in their pie chart, one by one.

- Labeling a graph: They label the graph to make it clear for others to read.

Grades to Use WIth:

This math project works well in the middle grades (4-8) when students know how to use protractors, calculate with fractions and decimals, and make graphs. It could also work well in a high school special education classroom.
