"If one day of the year screams Party! in math class, that day is March 14. Each year on 3/14, teachers in classrooms across the globe take a break from the normal routine to plan a special celebration in honor of pi, or the number 3.14... March 14 also happens to be the birth date of Albert Einstein -- which makes the day an extra special one for planning math challenges and math fun!" (Obviously my son's class is celebrating a day early.) Check here for fun ideas for any age.

Boy, don't you just feel smarter? How will you be celebrating Pi day? Measuring your waistline? Figuring out the diameter of the circle your children run in your house each day? Eating pizza, pies or thin mints?
