Who knew math could be so delicious? From the classroom to the kitchen, Pi Day gives families the opportunity to turn a math concept into a treat!

Pi, also symbolized by the Greek letter π, is a mathematical constant that represents the ratio of the circumference of a circle to its diameter. The circumference of a circle is the distance once around the circle, while the diameter is the length from one side of the circle to the other through its center.  When you measure the circumference of a circle and divide it by the measurement of its diameter, the result is always approximately 3.14, or pi (π). 

Pi Day is celebrated on March 14, or 3/14, as a nod to this famous number. But how can you make pi more exciting? 

The best (and the most delicious) way to celebrate Pi Day is by measuring pies! Baking itself is a perfect hands-on activity for ratios, and junior bakers can find pi (π) by measuring the distance around the outside of the pie and dividing it by a knife’s cut through the center from end to end. Not only will you find pi (π), but you will also get to eat the result!
