We celebrated National Pi (3.14) last week. The kids brought in their favorite type of pie to share with the class. Each child had to make a circle using a compass, measure the diameter and then use the formula for circumference (Pi times diameter) to find their circumference. Each child then made a Pi necklace or crown to wear for the day. We had over 25 pies brought in ! Needless to say our bellies were very full! Here are some pics of the fun day!
