Pi Day Math Activities

It's almost Pi Day! In this post, I share a few Pi Day math activities, including some math pennants, a Pi Day mobile craft and a couple new Pi Day digital math escape rooms. I also want to share some of the fun facts I've come across about pi over the years.

It's almost Pi Day! In this post, I share a few Pi Day math activities, including some math pennants, a Pi Day mobile craft and a couple new Pi Day digital math escape rooms. I also want to share some of the fun facts I've come across about pi over the years.

Here are a few Fun Facts about pi and Pi Day that would be fun to share with students on this great math holiday:

1: It took 1,000 years to prove pi irrational.

2: The first people to refer to the ratio between the diameter and circumference of a circle were the Ancient Egyptians.

3: "I prefer pi" is a palindrome.

4: Albert Einstein was born on Pi Day, 1879.

5: 22/7 is sometimes used to estimate pi.

6: The first major Pi Day celebration was in 1988.

7: Pi has been calculated past the two quadrillionth digit. 

8: P and pi are both the 16th letters in their alphabets.

9: You can likely find your phone number in pi. Here's the site that searches for it: http://angio.net/pi/. I found mine!

10: And the one that completely blows my mind: 3.14 backwards is PIE!

To celebrate Pi Day, I created three fun activities that let kids get artsy while not losing a day of learning. That one above is a Pi Day Math Pennant with area and circumference problems and fun pi facts on each pennant.

Some of the circle problems ask students to combine their understanding of the two circle formulas by finding area given circumference, for example. A fun challenge! There is also this metric version.

And here is a Pi Day pennant for middle school with less challenging circle problems any yummy fun-to-color pies. 

When the pennants are solved and colored, they can be hung along a string in your classroom to celebrate!

My friend Julia sent me this great photos of her students' Pi Day mobiles hanging from their classroom ceiling. Here's another photo from her classroom:

I bundled all 3 of the printable activities in this post (plus the metric version of the Pi Day pennant) in this discounted Pi Day Activities Bundle.

Since originally writing this post and to meet the needs of classrooms with technology, I have made a couple digital Pi Day activities. In this Pi Day digital math escape room, students solve 5 puzzles, each with 4 word problems to solve.

Here is puzzle #2 with Albert Einstein in a pizza shop:

The Pi Day escape room above is best for students who are comfortable with solving for certain variables within equations. For younger students, I made a Pi Day digital math escape room for middle school students that only covers finding area and circumference:


And here's one more crazy fact about pi: the sequence 999999 can be found in the digits of pi starting at digit #762. The probability of this happening is only .07%!


Happy Pi Day!

The pi day activity #10 isn't "backwards" its a reflection about a veetical line. An even better math activity.

I just wish Pi Day didn't land on spring break every year.
