NASA is joining schools, students and science centers across the U.S. to 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 NASA Pi Day Challenge! The illustrated math problem set gets students solving the same problems scientists and engineers do to explore space.
