What Is Pi Day?

First, you need to understand what pi is. Pi is the ratio of the circumference of a circle to its diameter. In simpler terms, it’s the number you get when you divide the distance around the circle by the distance across it. And the fascinating thing about this number is that it doesn’t end. It starts with 3.1415926535… and doesn’t end.

Why Is Pi So Important?

Pi appears in all sorts of mathematical equations and is used in fields ranging from physics to engineering. It’s essential for calculating the area and volume of circles and spheres and understanding waves and oscillations.

Why Pi Day?

Why Pi Day? Pi Day falls on March 14; in numerical terms, that’s 3.14. Get it? Those are also the first three digits of pi! It’s a fun way to introduce pi to kids and to bring a bit of math out of the classroom and into their daily lives.

Pi Day Activities

Pi Day is the perfect day to do something fun with the kids! From baking pies to games, there’s no end to the fun you can have with pi. And they’ll always remember what pi is once they’ve associated some fun activities with it. It’s also a chance to show them that you think math is cool. With some planning, you can pull off any of these fun educational activities with the whole family or kids of different ages.

“Celebrating Pi Day is one of our family’s favorite traditions. Each member of the family gets to choose one personal size pizza pie as well as also helps to choose two dessert pies for the entire family to share. When we have time we make them together from scratch, but also have had just as much fun eating the pies we order from local restaurants. It’s become something we look forward to year after year!” — Siobhan Borland, Fun Family Meals
