March 14th is Pi Day and I wanna do a thing. I want to teach our kids what Pi actually means.
Pi (π)…you know that thing kids proudly memorize as being approximately 3.14 or 22/7. I betcha though, if I asked most kids what pi actually represents, I think the majority wouldn’t know. So let’s teach it to them in a hands-on, fun, and memorable way.
Here’s what we did at our house…
Any pie: apple, cherry, pumpkin, sweet potato,…ummmm chocolate pecan pie…(sorry I got carried away in my thoughts there for a moment)…key lime, lemon meringue, peach…even a pizza pie will do. You choose. Store bought pies or pizza delivery will also work just fine…I won’t tell anyone!
Once your pies are ready, have your kiddos do two things: take the circumference and the diameter of the pie. Let’s break these terms down:
Since our pies are circles, it’s probably easiest to use a piece of string to measure the circumference.
Want to make it even cooler? Make two pies of different sizes. You’ll get to see how that ratio of circumference to diameter is the same no matter the size of your pie. Who said math can’t be cool?!
Want to get fancy? You can go a step further and learn how to use pi to find the area of a circle.
I will create a post on the Nicole the Math Lady Facebook Group. (If you’re not part of our closed FB group for NTML members, click on the link at the bottom of your email to request permission to join.) Post your photos/videos of your pies there. Help me create a little army of junior mathematicians who really understand pi. Can’t wait to hear how all about it!
