Pi Day

What is Pi??? It is the ratio of the circumference of a circle to its diameter. Regardless of the size of the circle, Pi is always the same number: approximately 3.14.

Physicist Larry Shaw created a Pi Day celebration 20 years ago on March 14 at the Exploratorium Museum in San Francisco. Schools around the world celebrate this special day with lots of fun math activities. Check out this video to see and listen to a rap song.



Now check out these great resources for Pi Day.
