7 Classroom Resources for Pi Day

Pi Day is coming on March 14, and the annual celebration offers a great opportunity for students to explore pi and math-related concepts! (Pi Day 2015 is extra special too, thanks to the aligning of the calendar.) Of course, there are plenty of great teaching resources online to help your class celebrate Pi Day, so we thought we'd help you sort through them all.

Here are a few of our favorites from around the web, starting first with an interesting music-related pi lesson, "What Pi Sounds Like," which was produced by musician Michael Blake. This video is a fun resource that can help students of all ages get excited about pi. Happy Pi Day!

  • San Francisco Exploratorium Pi Day Activities: Without the Exploratorium, official Pi Day celebrations might never have happened. In 1988, Exploratorium physicist Larry Shaw started the tradition, and it was finally recognized by Congress in 2009. The Exploratorium highlights some great hands-on activities on their Pi Day page, with links to useful pi-related resources.
  • Happy Pi Day, TeachPi.org: TeachPi hosts a trove of Pi Day resources, featuring fun classroom activities, Pi Day-inspired music, and other fun learning ideas. There's plenty here to keep students engaged and learning, on March 14. Check out the activities section for a bunch of great learning ideas.
  • Scholastic Pi Day Teaching Ideas: Scholastic produced this list of plans for three different grade spans: preschool - grade 1, grades 2-3, and grades 4-6. The page features interesting information about the history of pi, ideas for activities and a link to a web application for exploring the music of pi. Another great Scholastic resource is: "Writing With Pi."
  • PBS LearningMedia Pi-Related Resources: PBS LearningMedia features a great collection of geometry lessons related to pi on their site. These aren't specifically for Pi Day, but they're especially relevant on March 14. Plus, for more math and pi-themed lessons, OER Commons has curated more than 100 resources from a variety of sources.
  • What Is Pi, and How Did It Originate?: Scientific American dug deep into the history of pi in this article, offering an insightful look at the origins of the mathematical constant.
  • TeachersFirst's Pi Day Resources: TeachersFirst offers this great roundup of pi-themed lessons and resources from around the web, focused primarily on high school. Included in the collection are some general math resources, like Simpsons Math, and they all come from a variety of great sources.
  • Pi-Related Resources, Joy Of Pi: Author David Blatner is a pi fanatic, and his website Joy Of Pi features tons of useful and interesting information. Included on the resources page are links to sites that can help you learn the history of pi, how to calculate pi, and mysteries about the number.

When I taught second and third grade we always celebrated Pi Day. We would plan our circle geometry focus for right before and after Pi Day. It was amazing how excited we could get young children when doing hands on activities using Pi.

My favorites for younger elementary students are the cutting and seeing Pi activities found here:


My goal for these sorts of activities for early elementary age students isn't to come away with an understanding of Pi, but an EXCITEMENT for math!!! It provides them something to make connections to when these topics are introduced later in school.

Mathtricks.org just came out with a new online Pi Day game - "Pi vs Pie". Fun to play, the kids like it, and it makes them appreciate math.

We wrote Pi poems. My class may not fully understand Pi, but they used it to create some wonderful poems. Then we used the Tellagami app to create Gamis that recited the poems. We embedded the Gamis, along with the poems on Kidblog. Here's an example,
