Pi Day Activities
March 14th or 3.14 is Pi Day. Celebrate this lovable yet irrational number – whether you have a kindergartner or a middle schooler – with these activities:

Prove Pi
Wrap a piece of yarn or string around a cylindrical object and then cut. Now find out how many times the circumference string will go across the diameter: Place the string across the diameter of the object and then cut the string. Repeat until you’ve gone through the string.  Then amaze your child by repeating this process on a much wider or thinner cylinder to get the same answer: pi.
