A Plate of Pi

This project can be completed by a class or an entire grade.


  • Paper plates
  • Markers, crayons or paint


Hand out plates to your students and assign them a digit in pi. They should write their number and then decorate their plate however they'd like with their art supplies. After all of the students are finished, they can hang them up in the correct order in the hall, or even hold them and form a giant circle.

Quick Tip:

Help your students learn more about pi and how it is used in mathematics with this lesson on pi facts and history. This fun lesson can be used to reinforce what students are learning in the classroom and help them understand this activity.

Using the Pi Chain

Students can work on this project to see who can chain together the most numbers.


  • Construction paper (10 colors)
  • String


Have students work together to make loops out of the construction paper (each color should represent a number between 0-9). Students should add loops to their string to make it as long as possible. You can use this activity as a competition between classes or have all of the students work together to see just how long they can make their string! You can even have students try to form a huge circle so they can check out the circumference of their pi string.

Quick Tip:

Students can focus more on this subject with this lesson on how pi relates to diameter and circumference. Use this lesson to help keep your students engaged with this mathematical concept.


You can get students involved with Pi Day with this delicious take-home activity.


  • Pie ingredients


Have students work with their parents to bake a pi(e) of their own design. You can even turn this activity into a contest, with judges from the school or local area. Consider awarding students for the most creative pie, the best presentation or even the ugliest pie.

Quick Tip:

Encourage your students to learn more about other types of irrational numbers and discover the category of irrational numbers that pi belongs to through this simple and fun video lesson on irrational numbers.
