25 Best Ways to Celebrate National Pi Day

At the Governor's Academy for Engineering Studies, we think that math is beautiful, essential, practical, and fun.

Pi Day Ideas: 25 Ways to Celebrate

Calling all mathletes, engineers, scientists, and STEM teachers! Calling all math students and statisticians! (Yes, you!) Put down those calculators and tech gadgets, and get ready to celebrate!

Celebrate the Math Constant Whose Fun Never Ends

Whether you're a math nerd or a wannabe, March 14 is our day. It's the time when those of us who dance in the transcendent, resplendent beauty of numbers unite to celebrate our irrational love of pi.

Yes, pi (π) — that funny-looking Greek letter that represents the ratio of a circle's circumference to its diameter. No matter how large or small a circle is, you can divide the distance around it by the distance across it and get the same cool number. Mindbending, huh? (Let's take a moment.)

Abbreviated as 22/7 or 3.14, pi is a practical, universally applicable, and never-ending constant. Today, we use it in a variety of fields to determine area, surface area, and volume for objects that are

• circular
• cylindrical
• cone-shaped or
• pyramid.

Pi for Days . . . Well, One Day

Examples of disciplines that use it include astronomy, architecture, engineering, navigation, and construction.

To help get your Pi Day celebration off the ground, here are 25 ideas for honoring our favorite constant. Have a STEM-tastic celebration!

1. Write a Pi-Ku or Other Pi-Theme Poetry

Write a "pi-ku," a math version of the traditional haiku. While haiku is a Japanese poem with 17 syllables, broken out in lines of 5-7-5 syllables, the "pi-ku" is even more abbreviated. It follows a 3-1-4 syllabic pattern and enjoys a math-related theme. Here are some original samples to inspire you:

Pi transcends
pure
rational thought.

Beautiful
Math,
Your problems tease!

Elegant
Math ...
Universal.

2. Pi(e) Naming Contest

Challenge your friends to a pi/e naming contest. Depending on the type of friends you have (mathletes or mere wannabes), see who can name the most types of pie or the most digits of pi. Award a pie or pi-themed prize to the champion.

3. Eat Round or Pi-Inspired Foods

Why not combine two of your favorite activities—math and eating? There is no shortage of round-shaped foods. Consider round fruits (e.g., oranges, melon balls, bananas sliced in "coins"), round crackers, meatballs, round cookies, cupcakes, etc. To take the math theme one step further, consider the following pi-inspired foods. Some of them are a bit of a stretch, but hey—it's all in good fun!

Suggestions for Pi-Themed Foods

4. Play Pi Games

This will take some planning, but the fun will pay out in dividends. Think of the Instagram photos and the memories you'll take away from the event!

• Organize a pie-thowing or pie-in-the-face contest, with proceeds going to charity. Set a fundraising goal of $314, or more!
• Hold a pie speed eating contest, giving contestants 3.14 minutes, all the pie they can eat, with no hands allowed.
• Have "pi-ggyback" races, with two contestants holding a teammate horizontally (more or less forming a π) and racing other teams of three across a finish line.
• Learn to play the card game "pi-nochle" or beat a pi-ñata.
• Challenge yourself to name the digits of pi with an online game, such as the one here. Or, name words that begin with "pi," some as those in the online game here.

5. Hold a Pi Memorization/Recitation Contest

Pi is never ending and has been calculated to trillions of digits. But don't let that stop you from holding a contest to see who among your nerd friends can correctly recite the most digits. To assist in your training, Google even has a training app. Come on! You've got this!

6. Celebrate the Birthday of Albert Einstein

Since March 14 is also Albert Einstein's birthday, give a nod to the Nobel prize-winning theoretical physicist and philosopher of science by holding an Einstein look-alike contest and sharing Einstein quotes. There are so many myths about the genius that his birthday would be a fitting day to set the record straight.

7. Impress Your Friends with Pi or Math-Themed Trivia

Dazzle and amaze your friends as well as mere strangers with your knowledge of how pi is useful in geometry, engineering, trigonometry, astronomy, physics, and other endeavors. Point out practical problems that pi helps us solve. Remind them what 22/7 is and why it's important. Spread the enthusiasm!

8. Sponsor a Math Version of "Are You Smarter Than a 5th Grader?" or "Jeopardy"

In a back-to-basics challenge that features quick thinking, you might be surprised how easily math formulas, definitions, and basic concepts have gotten rusty.

9. Watch a Math-Inspired Movie

There are so many math-related movies to choose from. In the following films, for example, consider the role that math has had in history and in human relationships. Did math ultimately help unite people or separate them? Did it create new opportunities or barriers? (And if so, what kind?) Is it more a gift or a practiced skill? Go ahead—talk about the impact of math in our lives.

Movies With a Math Theme

10. Walk, Run, Jog, or Cycle 3.14 Miles

All that calculating can leave you antsy. Grab some friends and get moving! Hold a fundraising event involving 3.14 miles (or km if you wish) and donate the money to charity.

11. Hold a Pi Scavenger Hunt

For each digit of pi, divide your participants into groups and have them take photos of their found objects rather than bringing back actual items. Set a time limit and specify where they're allowed to roam, then disclose your pi scavenger hunt objects.

For the following digits of pi (3.1415926 ), here's an example of objects you might hunt for in a school environment:

• 3 scientific calculators
• 1 high-heeled shoe
• 4 vegetables
• 1 handshake with a teacher
• 5 university jerseys, each a different school
• 9 pennies, stacked
• 2 pipettes
• 6 mechanical pencils.

12. Send a Pi Day Card or Send an E-Card

Spread your infinite love of math with a card you make yourself or with an e-card, available here.

13. Take a Deeper Look at Pi

Write out as many digits of pi as possible and see if you can find you and your friends can find your birth dates, phone numbers, zip codes, social security numbers, and other personally identifying numbers.

14. Estimate Pi by Throwing Frozen Hot Dogs

Estimate pi using Buffon's needle, a problem of geometric probability. For an explanation of what it is, click here. Whether you drop needles or toothpicks on a sheet of paper or throw frozen hot dogs on the floor is up to you.

15. Tell Pi Puns and Math Jokes

Who says math isn't funny? Relax a little and tell a few math jokes. Here are some to help get you started.

15 Pi Puns and Math Jokes to Tell Your Friends

16. Entertain Your Friends by Using as Many "pi" Words as Possible Today.

Examples include: pi-lot, pi-zzazz, pi-ous, pi-rate, pi-neapple, pi-lates, etc. Be sure to emphasize the "pi" syllable and keep it up, even if you receive eye rolls. It's one day a year, folks. Your friends can tolerate the math madness for 24 hours.

17. Wear Math-Themed Apparel

There are a number of clever math t-shirts available, as well as pi earrings. Don't be afraid to proclaim yourself a math nerd.

After all, you're in cool company. Think Albert Einstein, Bill Gates, Steven Hawking, Sergey Brin (Google's co-founder), Marie Curie, and many more. All were math majors in college.

18. Create Your Own Pi Art, or Admire That of Others

Take a camera and explore the world around you. Where can you find the symbol pi? How can you express yourself creatively and artistically in representing the Greek letter or the digits of pi? (Examples of what others have achieved are shown below.) Or, if you prefer, admire the art of Salvador Dali, a famous artist who used the principles of pi and phi in his art.

Can you find pi in your environment at school, at home, or in nature?
