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 funnylooking 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 neverending constant. Today, we use it in a variety of fields to determine area, surface area, and volume for objects that are
 circular
 cylindrical
 coneshaped 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 STEMtastic celebration!
1. Write a PiKu or Other PiTheme Poetry
Write a "piku," a math version of the traditional haiku. While haiku is a Japanese poem with 17 syllables, broken out in lines of 575 syllables, the "piku" is even more abbreviated. It follows a 314 syllabic pattern and enjoys a mathrelated 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 pithemed prize to the champion.

3. Eat Round or PiInspired Foods
Why not combine two of your favorite activities—math and eating? There is no shortage of roundshaped 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 piinspired foods. Some of them are a bit of a stretch, but hey—it's all in good fun!
Suggestions for PiThemed Foods
pineapple  pierogies 
piancakes  piita 
piickles  pianini sandwiches 
pitatoes  pitato chips 
piinto beans  piretzels 
pimento cheese sandwiches  pistachio nuts 
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 piethowing or pieintheface 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 "piggyback" 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 "pinochle" or beat a piñata.
 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 prizewinning theoretical physicist and philosopher of science by holding an Einstein lookalike 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 MathThemed 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 backtobasics challenge that features quick thinking, you might be surprised how easily math formulas, definitions, and basic concepts have gotten rusty.
9. Watch a MathInspired Movie
There are so many mathrelated 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
The Theory Of Everything (2014)  The Imitation Game (2014) 
An Invisible Sign (2010)  21 (2008) 
A Beautiful Mind (2001)  Pi (1998) 
Good Will Hunting (1997)  Stand and Deliver (1988) 
Moneyball (2011)  A Brilliant Young Mind (2014) 
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 highheeled 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 ECard
Spread your infinite love of math with a card you make yourself or with an ecard, 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.
