Irrational Fun with Pi Day

pi videos With the use of computers, pi, the ratio of the circumference of a circle to its diameter, has been calculated to over 1 trillion digits past the decimal. Pi is an irrational number, which means it will continue infinitely without repeating. Pi is equal to about 3.1415926535…

We often estimate pi to be about 3.14. As such, Pi Day is celebrated annually on March 14, in accordance with Einstein’s birthday, by math enthusiasts around the world.

Pi Day falls on a Sunday this year, but you can still incorporate fun Pi Day festivities with your kids. Children of all ages love celebrating the magic of numbers. There are many ways to incorporate the event into your curriculum.

Pi Bee

Every year my kids participate in a Pi Bee. The children have one day, night, or weekend to memorize as many digits of pi as they can. You will be amazed at how many digits of Pi your children will memorize. Last year’s winner memorized 89 digits of pi in one morning!

The winner received a large pie to take home to their families and a ribbon. Kids get engaged and motivated about the beauty and magic of numbers and still talk about pi day, years after. To introduce the Pi Bee I start off with the video below.
