# Top Ten Ways to Celebrate Pi Day

Pi Day is celebrated every year on the fourteenth of March around the world, and although we’re not celebrating actual pies, there can be pies involved in the celebration. Pi is used to represent a mathematical constant. Not only is it the ratio of a circle’s circumference to its diameter, but it’s also the 16th letter in the Greek alphabet (π). With Pi Day quickly approaching, here are ten ways students can celebrate its arrival.

## 1. Eat Pi Foods

A celebration without food is not a celebration. On this day, have students eat foods that start with “Pi.” Why not start with actual pies? Pizza and pineapples, or pineapples on top of pizza are other examples of Pi foods. You can go a step further by having students measure the diameter and circumference of the pizza pies and regular pies before they eat them. This way they’re eating and learning at the same time. It’s a win-win.

## 8. Sir Cumference and the Dragon of Pi

One book in a much larger series, Sir Cumference and the Dragon of Pi is the perfect book for a Pi Day read-aloud about math. Titular character, Sir Cumference, has been changed into a dragon. Because of this, his son, Radius, and Lady Di of Ameter are tasked with searching for clues to a riddle that can change him back to a human.

## 9. Pi Day Paper Chains

Pi Day paper chains is a fun activity that students can do as a large group. You can create a Pi Day chain using loops of construction paper. Make sure to use different colored paper for each of the ten digits, and each will represent either a decimal place or a digit. Because Pi is constant, there’s no telling how long your paper chain can go for. Why not try to set a world record?

## 10. Create Pi-Related Artwork

Creating artwork is a great way for students to showcase creativity while simultaneously learning about math! Students can make Pi-lentines, which are appreciation cards for the people they appreciate the most with the addition of some witty Pi puns. Another way that students can be creative includes using markers or crayons to graph the digits of Pi in bar graph format on a piece of graph paper. They should do this repeatedly until it looks like a skyline across the paper. After they are done graphing their skyline, invite students to color in their buildings and the sky.
