Are you ready for Pi Day on March 14? Do you already have your Pi Pie recipe picked out and ready to bake (and then etch with a laser)? GREAT! Now, what to do while it bakes…

NASA’s Jet Propulsion Laboratory has the answer! JPL has assembled a range of activities that will keep both classrooms individual geeklets busy studying math and having fun.

Pi In the Classroom:

The 2018 NASA Pi Day Challenge – The fifth installment of NASA’s illustrated math problem set features four new challenges that get students exploring space with pi.

Teachable Moment: Pi Goes the Distance at NASA – Learn about the science behind the 2018 Pi Day Challenge, including related resources for educators and how to make Pi Day one of those acclaimed Teachable Moments.

Pi in the Sky Lessons – Explore the entire online catalog of NASA Pi Day Challenge lessons for grades 4-12. Each lesson includes an illustrated poster or handout and answer key, plus a list of applicable Common Core Math and Next Generation Science Standards.

Pi at Home:

NASA Pi Day Challenge – All 20 illustrated math challenges from the “Pi in the Sky” series can be found in one, handy slideshow for students.

How Many Decimals of Pi Do We Really Need? – Have you memorized more than 70,000 digits of pi like other world record holders? A JPL engineer explains why that is crazy (because you really only need a tiny fraction of that for most calculations).

My Pi Is the Greatest

Think you’ve got an amazing Pi Day pie? Want to show off your math skills to everyone on the internet? Check out Pi Day: What’s Going ‘Round to tell NASA how you’re celebrating Pi Day this year and see some great contributions from other geeks around the planet!


Pi (π) is the ratio of a circle’s circumference to its diameter. Pi is a constant number, meaning that for all circles of any size, Pi will be the same. Pi is also an infinite number, often abbreviated to 3.14 (a number bearing a striking resemblance to March 14).

Pie is a delicious food with a crust and various fillings, often topped with more crust or a meringue suitable for laser etching.
