Whoever knew there would be a Pi Day? And that it would become such a big deal?! But it’s brilliant! The first few numbers in pi are 3.14, so Pi Day is always celebrated on March 14 … 3/14!
I love the idea of a day to celebrate a math concept. And it’s a perfect day for Montessori educators and families, too … a day basically to celebrate the love of learning.
Pi Day is fun to celebrate for multiple ages. While preschoolers won’t really understand what pi is, they can learn that pi relates to circles, do circle activities, do pie activities, learn to identify the pi symbol, and learn the first few numbers in pi. Through the 3-period lesson, older preschoolers can learn circumference and diameter. With lots of hands-on activities, all can get the idea that math is fun!
Of course, elementary-age kids on up can learn that pi is the ratio of a circle’s circumference to its diameter, which is approximately 3.14159. They can learn that the true value of pi can’t be calculated because pi is an irrational number with decimal places that continue forever without repeating. They can do all sorts of fun Pi Day challenges. And they might even like to learn about the history of Pi Day.

2020 Update: I’ve put out a simple Pi Day activity for this year that Zoey and my toddler grandkids can all enjoy. Zoey loves the book Sir Cumference and the Dragon of Pi (actually the Sir Cumference books in general)! I featured our circle inset on a single inset tracing tray from Amazing Child Montessori on Amazon (I love Amazing Child Montessori’s materials!), but it isn’t available right now. There are some other metal inset tracing trays available, although they take up a bit more space on the shelf.
