# Celebrate Pi Day With NASA on March 14

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: 3.14, or 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 the date 3/14 has been designated National Pi Day.

Looking for educational resources and activities to add to your Pi Day celebration? Check out these free offerings from the Education Office at NASA's Jet Propulsion Laboratory:

## NASA Pi Day Challenge

 Each year, the JPL Education Office creates an illustrated Pi Day math challenge that features real-world problems NASA scientists and engineers solve to explore space. The 2019 challenge will be available as both a standards-aligned lesson for the classroom and as an activity students can do on their own. Answers will be released the day after Pi Day. Explore our collection of lessons and problems from previous years' challenges at the links below, and check back on March 8 to participate in the 2019 NASA Pi Day Challenge! The 2019 challenge goes online March 8! › For Educators: Pi Day Challenge Lessons › For Students: Take the NASA Pi Day Challenge (slideshow)
