Monday, 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.
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. You could even take a vote to see what kind of pi your kiddos want to make. Your task is to get the ingredients and make it.
Once it’s made, 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.
You 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?!
I will create a post on the Nicole the Math Lady Facebook Group on Monday. (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!
