Pi Day is just around the corner! On March 14th, fans of math and pie come together to celebrate π, which is the ratio of the circumference of a circle to its 3.14. They often do so with a great deal of humor, and I was cracking up at some of the fun items I found to help make your Pi Day as fun and festive as possible. Here are Pi Day products that you didn’t know you needed, but do.

How perfect is this pi pie? I love this pie pan so much. So. Much. Forget the fact that I have no idea how I’d actually make a pie crust for this.

Less ambitious bakers may find that this Pi-shaped cookie cutter is more up their alley.

**Come To The Math Side We Have Pi T-shirt**

Star Wars and Pi Day together? Yes, please!

I’m also loving this shirt.

Because footwear matters, and so does Pi.

**I Ate Some Pi And It Was Delicious Travel Tumbler**

This is “I 8 sum” pi, or “I ate some Pi.” Pi humor and warm coffee equal a great morning.

Okay, it’s pretty likely that you don’t actually *need* this shower bench, but if you’re married to a math major like I am, it could be a big hit.

**3.14 and PIE Coincidence Tall Mug**

I do *not* think it’s a coincidence, do you?

I don’t use a mouse any more, but I kind of want this anyway.

There are also several great books on Pi, including:

* Sir Cumference and the Dragon of Pi* by Cindy Neuschwander

The title of this book has me wanting it, regardless of the fact that Amazon recommends it for kids in middle grades.

* Why Pi?* by Johnny Ball

The book *Why Pi?* examines on how Pi and numbers in general have been used to measure things, from how the ancient Egyptians measured the pyramids to the ways that current day scientists calculate time and space. Amazon says it’s best for grades two through five.

** Piece of Pi: Wit-Sharpening, Brain-bruising, Number-Crunching Activities with Pi** by Naila Bokhari

This offers lots of math fun for your numbers-loving middle schooler.
