Pi Day

Tomorrow, March 14th, will be Pi Day, a day for celebrating the number 3.14.  The number called Pi has been used for thousands of years in order to measure circles.  Read Sir Cumference and the Dragon of Pi to help students get acquainted with the number.

Learn more about the history of Pi from Exploratorium.  Also check out their page of hands-on activities to help students understand the value of Pi.

Have fun with language connections by making pies and discussing homophones and how they can sometimes cause confusion.  Decorate your pies with these clever printable tags from Don't Eat the Paste.

*Edited to add, we decided to celebrate Pi Day with a Soda Cracker Pie, which is a surprisingly yummy treat made of saltines, egg whites, and nuts.
 It's a weird combination that turns out delicious.  Since the ingredients are so cheap, my husband called it Poverty Pie.  For at least a hundred years, in times when resources or money have been scarce, crackers have been a secret ingredient in pies.  Settlers of the American West, who wished for apple pie but had no apples, made Mock Apple Pie with crackers and lemon juice.  During the Depression, a handful of nuts became an entire pecan pie when supplemented with soda crackers.  You can make your own Poverty Pie and then discuss how necessity is the mother of invention.
