Pi Day was Thursday, March 14, 2013, and the fifth graders at East Salem Elementary School learned all about Pi!
The students started off by measuring the circumference of small whipped cream pies before gathering together in the school cafeteria to put together a 500-link long paper chain outside, with each link signifying the first 500 decimals in Pi.
Every class in the school had a hand in creating the enormous paper chain. You can see photos above, or video below to get a feel for how mammoth the chain really was!
[UPDATE March 18, 1:08 p.m.: Fifth grade math teachers Peggy King and Carrie Poff coordinated the Pi Day events, including each classroom's participation by decorating the individual links.]
