Celebrate Pi Day


March 14


Each year on March 14, classrooms break from their usual routines to observe the festivities of "Pi Day" - so called because the digits in the date correspond with the first three digits of pi (3.14). An added bonus - Albert Einstein was born on March 14 (in 1879).


Here are some resources to help you get ready for the big day:
