Pi Day is March 14 every year, a Sunday in 2027. The date written 3/14 matches the first three digits of pi, 3.14. The U.S. House of Representatives passed a resolution supporting National Pi Day in 2009.

Pi is the number you get when you divide any circle's circumference by its diameter. It starts 3.14159 and its digits never end or repeat. The What Is Pi? poster and the Pi Word Mat explain it for 3rd to 5th grade.

What hands-on Pi Day activities work for 5th grade?

Measure Round Objects Pi Challenge and Circle Hunt Around the Room have students measure real circles and divide the circumference by the diameter to get close to pi.

Are there Pi Day activities for younger children?

Yes. K to 2nd graders can use the Pi Day coloring pages and the Circle Spotter Hunt, and every grade can help hang the Happy Pi Day and Digits of Pi banners.
