K12 students and educators, parents, museums, science centers and planetariumsOverview:
On March 14, NASA will join schools, students and science centers across the U.S. as they celebrate one of the most well known and beloved numbers: pi. Used throughout the STEM world – especially for space exploration! – pi is the number that results from dividing the circumference of any circle by its diameter. Pi can be and often is rounded to 3.14 (even though its decimals never end), which is why 3/14 has been designated National Pi Day.
Educators and students can participate in honoring this mathematical marvel by taking part in the 2020 NASA Pi Day Challenge starting Friday, March 6. The illustrated math problem set gets students solving the same problems scientists and engineers do to explore space. Explore previous challenges and even more pirelated resources for educators and students below!

How Many Decimals of Pi Do We Really Need?
While you may have memorized more than 70,000 digits of pi, world record holders, a JPL engineer explains why you really only need a tiny fraction of that for most calculations.
