Pi Day Activities for the Classroom

Every year on March 14, Pi Day gives us a reason to enjoy our favorite sweet and savory pies and celebrate the mathematical wonder that helps NASA explore the universe. Students can join in the fun by using pi to explore Earth and space themselves with the NASA Pi Day Challenge.

What is Pi Day?

Dividing any circle’s circumference by its diameter gives you the mathematical constant pi (π), which is usually rounded to 3.14. In the United States, March 14 can be written as 3.14, which is why that date was chosen for celebrating all things pi!

You may already know all about pi and how it can be used to calculate things like the circumference of a circle or the volume of a sphere. But did you know pi is also used all the time by NASA scientists and engineers to explore other planets?

Explore our lessons and problem sets to solve some of the same problems NASA scientists and engineers do using pi!
