So what is “Pi Day?”

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. Pi has been calculated to over one trillion digits beyond its decimal point.

Why March 14?

Pi is what’s known as an irrational number, meaning its decimal representation never ends and it never repeats. It has been calculated to more than one trillion digits, but 3.14 is often a precise enough approximation, hence the celebration occurring on March 14, or 3/14 (when written in US month/day format). The first known celebration occurred in 1988, and in 2009, the US House of Representatives passed a resolution designating March 14 as Pi Day and encouraging teachers and students to celebrate the day with activities that teach students about pi.

Pi Day

Some of us make pie and other people, like math and science game wizard Cy Tymony focus on teaching people fun ways to enjoy and learn more about science and mathematics. Cy is the author of the young adult educational book series “Sneaky Uses for Everyday Things”. These books are packed with cool math and science games and projects for kids and teens to play.

This year Cy created www.PiDayFun.com – an educational website dedicated to making Pi Day math memorable with free tips on how kids can have lots of fun using discarded items and without special tools. The site contains 5 Free ‘Pi’ and Math Projects.

There’s a free download for a whole set of Pi Cards, and directions on how to create a Sneaky Pi Detector, and instructions on how to make a Sneaky Pi Quizzer.

A huge thank you to Cy Tymony for making my Pi Card and for sending a Sneaky Pi Detector along with it. We’re having so much fun with Pi. Cy will be back on Jump into a Book a bit later with his new Sneaky Math book.

Want to learn how to recite Pi to 100 digits in 4 minutes or less? Common, who’s Brave? 

It’s time to be on a memory mission. Did you know that the more digits of pi you memorize the easier it will be for you to learn math ? It’s true. Research from Harvard shows that the more you memorize pi, the better your brain works mathematically.

Pi Day Carols

In honor of Pi Day I think we need to gather around the piano, or pull out the guitar or something and sing these favorite Pi Day tunes such as:

Oh, Number Pi (to the tune of ‘O, Christmas Tree’)

Ludolph the Mathematician (to the tune of ‘Rudolph’)

Pi Day Time (to the tune of ‘Silver Bells’)

Ring the Bells (to the tune of ‘Jingle Bells’)

You can find words, music, and sing along sheets here.
