Celebrate Pi Day on March 14!

March 14 marks the annual celebration of Pi Day. Embraced by math lovers everywhere, this unique day recognizes the irrational number Pi (or ℼ). Pi is the ratio of a circle’s circumference to its diameter, which is always 3.14. Hence, we celebrate Pi Day on March 14. Around the world, people commemorate advances in math on Pi Day, and you can take part too with these fun activities.

Create a DIY pizza pie bar.

Set up a pizza making station at home to celebrate Pi Day. Give each person a pre-made crust and allow them to customize their pizza with toppings of their choice. Encourage pizza makers to incorporate the ℼ symbol or other mathematical designs (think fractions or addition problems) with their toppings.

Watch a math-themed movie.

Movies about math cover many topics, making it easy to find one to enjoy! For older viewers, watch Good Will Hunting, 21, Moneyball or A Brilliant Young Mind. Great family-friendly math-inspired films include Life of Pi, Hidden Figures, and Queen of Katwe.

Have a pie eating contest.

Gather your friends and family for an old-fashioned pie eating contest. Make mini pies of your choice or go all out with regular sized pies. While the first person to finish their pie is the ultimate winner, be sure to have an award on hand for the messiest eater as well!

Exer-pies.

You don’t have to eat or watch a movie to commemorate Pi Day. Find a 3.14-mile route in your neighborhood and go for a run, walk, or jog in honor of the world’s great mathematicians. If you prefer interval training, use 3.14 to guide your sets.

Play Pi games.

Pi-themed games can be played by people of all ages! Since Pi is related to circles, find as many perfectly round circles as possible throughout the day. If words are more your thing, have a contest to see who can come up with the most words that begin with “pi-” in a set amount of time.
