π! Sweet Pi Day Activities for Kids

What has its own special symbol, is irrational, goes on forever, and is celebrated on March 14th every year? π! So, what is Pi exactly? Pi is the ratio (a relationship between two numbers) of a circle's circumference (the distance around the circle) to its diameter (the distance across the center of the circle), meaning it can be used to find the size of circular objects. What’s amazing is that with every size circle you have, whether it’s a yummy pizza or the spinning wheel on your bicycle, this ratio always stays the same. Because the true number continues infinitely without repetition or pattern, we just use its first three digits of 3.14 for approximation. While the US government didn’t officially recognize Pi Day until 2009, the first celebration was actually held in 1988 at San Francisco’s Exploratorium by physicist Larry Shaw. He gathered people to eat pies (since pie is circular and a homonym for Pi) and march around in circles. So, how will you celebrate Pi Day this year? If you’re looking to join in on the STEAM fun to be had, we’ve put together this list of DIY Pi Day activities for kids to try! You’ll find math art projects to make, pies to bake, songs to sing, and more. From all of us at KiwiCo, Happy Pi Day!
