Every year on March 14th, we celebrate Pi Day honoring the mathematical constant π (pi)—the ratio of a circle’s circumference to its diameter. As an irrational number, pi’s decimal expansion goes on forever, making it a fascinating subject in math, science, and engineering. Pi is everywhere! It’s used in geometry, physics, space exploration, and even art. From designing bridges to understanding planetary orbits, pi helps shape our world.

Fun Ways to Celebrate

• Eat Some Pie 🥧 – A tasty way to honor “pi”!
• Memorize Digits – How many can you recall?
• Explore Pi in Nature – Look for circles in tree rings, shells, and flowers.

Pi Day is a fun way to celebrate math and curiosity—whether you love numbers or just love pie! Happy Pi Day!
