Pi Day is March 14! Pi, represented by the greek symbol π, is the ratio of a circle's circumference to its diameter. Draw any circle, and that ratio is always 3.14.

According to Wikipedia, “Pi Day is an annual celebration of the mathematical constant π. Pi Day is observed on March 14 since 3, 1, and 4 are the first three significant digits of π. It was founded in 1988 by Larry Shaw, an employee of the Exploratorium. Celebrations often involve eating pie or holding pi recitation competitions.”

Simply put, Pi Day equals yummy math. What better way to promote a love for math? Here we have compiled some kid-friendly pie recipes. Have fun baking together. And incorporate more math by having the kids do the measurements or unit conversions, keep track of baking time, and dividing the pie into equal slices.
