Saturday, March 14 was National Pi Day. This year's Pi Day was especially significant as the date corresponded to the first five digits; an event that occurs only once in each millennium.

We celebrated Pi Day today, March 16. We measured different circles to derive Pi ourselves. We got pretty close to 3.14 in our measurements! Then we examined the first 100 digit of Pi and created paper chains. Each color in the chain corresponds to a different digit.
