March 14 marks the very underrated “Pi Day”, a celebration of a “constant” – the ratio of the circumference of a circle to its diameter, calculated to 3.14159… (and on and on infinitely without pattern or repetition).
Pi Day is a holiday for math lovers. Originally approximated by the great mathematician, Archimedes, Pi has been calculated to more than one trillion digits past the decimal point. The infinite nature of this irrational number makes it fun for number-lovers everywhere.
Here are some fun ways to celebrate Pi!
Run a Pi Day 5(+.04)K
Get the family or friends together to run 3.14 miles on March 14, to honor the iconic number. You can organize this on your own or through a virtual run company like Pi Day 5K through FitFam. All you need are running shoes, a means of mapping out a safe course and water.
Craft it out
Make a “Pi” chain using paper loops or beads. Assign a color of paper or bead for numbers zero through nine, and then staple or string together to see how long you can go. Be sure to point out the lack of pattern or repeating numbers as you go.
Measure different circles around the house. Use a tape measure to record the circumference and diameter and then help kids divide the two to see how Pi doesn’t change from item to item.
Read all about it
The local library yields a wealth of information about Pi – from biographies on Archimedes and Sir Albert Einstein (another of history’s great geniuses), to fun stories like Sir Cumference and the Dragon of Pi (A Math Adventure) by Charlotte Neuschwander. Whether choosing fact or fiction, the story and importance of Pi can easily be brought to life for math lovers of all ages.
Bake a Pie
Of course, pie is the traditional dessert of Pi Day. This recipe has been passed down by my great-grandmother and kids are easily able to help out with the measuring and mixing. To fancy it up, you can always shape leftover dough into a Pi symbol and attach to the top crust with a little bit of egg wash before baking.
Bonus activity: Use a tape measure to have your kids measure the diameter and circumference of your actual pie. Divide the circumference by the diameter and see the results!
