This post can also be found on the Our World, Our Numbers blog. Along with this information about recipes and how we tied them in to Pi Day, you’ll also be able to learn about recipes from other countries around the world. Check back next week as each class posts about a new topic!
With recipes being the topic this week, it tied in perfectly with today. It just so happens that today is March 14, which here in the United States we often write as 3-14. Well, this represents a very important number in math. It represents a number that we call pi. Now that’s not pie, like the kind you eat. We’ll get to that in a minute. Pi (π) is often written as 3.14. That represents the number of times that the diameter of a circle fits into the circumference of a circle.
Every year, we like to celebrate Pi Day because it’s something that we learn about it sixth grade. We use pi (3.14) to find both the circumference and area of a circle. The circumference is the distance around a circle. The area is the amount of space inside of a circle (or how many square units can fit into a circle). To celebrate, students bring in pies (not numbers but the actual food). We measure each pie to find the radius and diameter of it. Then, we use those numbers to find the circumference and area! Check out some pictures from our day below.
If you’d like to learn a little bit more about circumference and area, you can watch two of our Math Movie Network videos from last year.
Some students brought in recipes for the pies that they made. We’ve shared them in the presentation below. You can learn about some of the common types of pies that we eat in here in Massachusetts and then you can see how you can make it at home!

Dear Mr. Avery,
My favorite type of pie would have to be chocolate cream pie. I’m sad that I had to miss pie day because of me being sick. It looked really good and sounded really fun to me.
Sincerely,

Hello Mr. Avery & Class,
I love pi! As Mr. Avery knows I memorized over 100 digits of it! Well I only recited 80 somthing digits correctly, though I did feel like my head was going to explode numbers… 😀 Anyways, How did you all like Pi day? I personally like Tau…Pi is considered wrong! Go Tau day! Celebrated on 6-28 every year! Byr For Now!

Dear Tessa,
