Celebrate Pi Day in your school!  If you don’t have time to bake a Pi-pie (for fun – make it square – pie are square), here are some other ideas of how celebrate!

  • Pi Recipes – NPR
  • Music – YouTube Pi composition to 31 decimal places – with some basic music theory thrown in!
  • Wear Pi t-shirts
  • Convert things into pi. This step is absolutely necessary for two reasons: To utterly confuse people who have no idea what you are talking about (thus opening the door for enlightenment) and to have fun seeing how many things can be referenced with pi.Consider two approaches:
    • Convert naturally circular things into radians like the hours on the clock. Instead of it being 3 o’clock, now it’s 1/2*pi o’clock. Or, instead of it being 3 o’clock, convert the inclination of the sun into radians and describe that as the time.
    • Simply use 3.14 as a unit of measure. Instead of being 31 years old, you are 9pi years old (approaching your 10th birthday). With this same approach, you can find out your next pi birthday (don’t forget to celebrate it when it comes!).
  • Play pi games and make strange mathematical endeavors. These are in the same step because many math nerds consider them the same thing. There are plenty of traditional games that are appropriate on Pi Day, like a pinata, a pie-eating contest or pie-in-the-face fundraiser, etc.
    • Play Pi Day versions of “Are You Smarter Than a 5th Grader?” or “Jeopardy;” conduct a Pi Day Scavenger Hunt.
    • Of course there are more intriguing things to do like writing a pi-ku or pi-em, holding a pi memorization or recitation contest, discussing different ways to derive pi, seeing who can write pi in the most noticeable (though legal) place on campus, at work, etc., calculate the average error experienced when using 3.14 as an approximation, finding your name, birthday, ATM pin, etc. in pi, finding pi in pi, or discussing what things would be like without pi (the earth being a square and so on). This list could literally go on and on; hopefully this is enough to give you ideas of your own.
    • Have contests (preferably with two or more people who know about pi) to see who knows the most digits of pi.
  • Do a pi mile run. Go on a run for pi miles. You can take this a step further by organizing a pi mile run.
  • High School Math Classroom Activities
  • … and more ideas from the National Council of Mathematics Teachers

Have Fun!
