As we learned during math class, pi or π is the symbol representing the number you get when you divide the circumference of a circle by its diameter. No matter the size of the circle, the ratio between these two is always the same number. The 14^th of March (3/14) makes it a perfect day to celebrate pi and show our appreciation of math and science since 3, 1, and 4 are the first digits of this special number.

Whether you are a teacher that wants to shake things up in the classroom or a parent that wants to get inspired to set up some new family activities, the following ideas are a great start before planning this year’s celebration.

This is a perfect activity for small children and a great opportunity to help them memorize some of the pi digits and see that math can be fun! Luckily there are many songs out there that celebrate pi so you have a wide selection to pick your favorites.

If you know how to play the piano and want a more challenging activity, there is even a piano piece, in which each number is represented by a different note.

Another fun way to learn about pi is to create some pi art. Depending on the age and the available materials, there are many types of projects you can do with your children or students.

Elementary students that have learned to do some basic operations will have a lot of fun with a coloring page project. You can download this worksheet, in which the letter π is divided into sections that need to be filled with color according to instructions. To find which color to use, the students need to solve an operation, making it a fun way to solve simple math problems.

To celebrate the infinity of pi, TinkerLab had the idea to create this art project where you have to choose three colors, spend 14 minutes, and paint 15 boxes. Where is the infinity on this? There are countless ways to fill the grid!

For older children, the Pi City Skyline project is an awesome way to learn the first digits of pi and at the same time create something very artistic they can even gift to their math teacher!

The idea behind this is simple. Each building in this cityscape represents several pi’s digits. You can create a colorful city by assigning a different color for each number, or keep all buildings black and paint a colorful sky behind.

If you love math, why not create something you can also wear? A fun project for teens and even adults is crafting pi shirts. You can pick some colorful fabrics and sew the letter π on one of your  shirts, or use a π stencil to create stamps!

You can craft a pi bracelet (or necklace) in the following two ways: either as shown below (number of beads equals the value of the digit) or assign a different bead color to each digit. For example, you can assign white to 0, blue to 1, and so on. If you don’t have any beads available, you can also do this by coloring pasta and using them as beads.

Why not decorate your classroom or your children’s rooms to celebrate the day? You can create some pi pies with Playdough, decorate a plate or bowl by painting the pi digits around the rim or even hang some decorative garland with pie pieces. Just like pi’s digits, the possibilities are infinite, and you can get even more ideas by scrolling through Pinterest boards.

Another cool way to learn about pi and have fun is by playing some pi games! A fun project for younger children is the pi spy game, in which it is required to search and identify the π symbol among other mathematical symbols. Apart from being fun, this game also improves comprehension and focus.

For older children and adults the pi card game is the perfect family event! The game’s objective is to be the first player to play all the cards in your hand. To play a card, though, you need to have the next pi digit in your hand, or you lose your turn.
