In celebration of Pi Day (March 14), I have put together a couple of Pi Day Activities to make the celebration even more fun! The first is a sing along with silly Pi Day songs that can be used with any age.

The second is an investigation to discover the meaning of the number Pi and the formula for circumference! This is intended for 6-10 graders, but could be adapted for use in the elementary setting with appropriate teacher or parent help.
