Any excuse to celebrate gets me excited. Combine the glories of math with the deliciousness of pie (both dessert and savory)? * I am All In*!

In this post you will find a round-up of amazing videos, books, art projects, music, recipes, and math activities to delight all ages.

Yeah, get out your microscope and you’ll see it’s actually the first million digits of π!)*! I also have a printable Pi Day Menu (all round foods, please) for your perusal.

## What is π?

Pi (π) is a mathematical constant. It describes the ratio of a circle’s circumference to its diameter: Pi = Circumference/Diameter. It is an irrational number (it cannot be described by a fraction), and there does not appear to be a pattern in the digits in its decimal representation. Pi (π) is most simply rounded to the approximate value 3.14. *(Thus: 3/14, March 14}*

- That time
**Pi Day was almost March 2** - What if you translated
**Pi into music**on saxophone or piano? - Or turned
**pi into colorful art**? - Watch how we could
**calculate Pi…with pie**s. - Maybe we should just
**bake some pies**. Yum! Here are 20 recipes to celebrate Pi Day. **Pi Day Party Schooling**with Dachelle- Create a
**Pi Cityscape** - Learn About
**Pi With LEGO® Bricks** - Remember the printable Pi Day Menu available to Humility and Doxology email subscribers? Take all your
**round foods**(or other circular objects) and demonstrate pi with string! **Buffon’s Needle is a classic geometric probability problem**, involving dropping needles on a lined page and calculating the probability of one of the needles crossing a line on the page. The probability is related to pi! You can try the experiment on your own at home, or if (like me) you’d like to avoid dropping hundreds of needles, you can use this app simulation.- Do you have a puzzle-lover? Try this

**Why Pi is STUPID!**(ok, Vi, I get it, but I want to eat pizza and key lime pie, please, so let me have my fun!) - And if you really want to get her going (or you have some trigonometry students at your home who are a bit grumpy about pi and radians and what not these days), check out her Pi Is (still) Wrong video. I guess we could try to have

**Pi Day is also Albert Einstein’s birthday**, did you know? Even more excuses to party!}

Rachel at day2dayjoysLove this list of things to do on pi day, how cool!

Amy SloanThanks! I hope you find some fun ideas to use this year or in the future. 🙂

Tonya NolanThis is so great. I have a Pi Day t-shirt to wear to class. I may have to celebrate the week before and use some of these ideas!

Amy SloanI hope you do!

Nina NicholleI love the pi day menu

Amy SloanCan’t go wrong with pizza and cookies, right? 😉

Melanie FultonWe love Pi Day here. In fact, we used to all have pi shirts before some outgrew them.

Amy Sloanthat’s awesome 🙂

Rachel GWe’ve never done anything for Pi day, but you’ve inspired me!

Amy SloanSome years we go all in and some years we keep it simple, but we’re just nerdy enough to get a kick out of it every year. 🙂

Mary CPi Day was our favorite! I loved especially that it excited my youngest son so much. In 2015, when we could express Pi to the time of day at 9:26AM, he exclaimed how “cool Pi Day would have been in 1592!”… except it apparently was not expressed by the Greek letter until the 1700’s. I am definitely ordering the “I ate…” t-shirt for him and sending it with cookies, as he is far from home in the military this year! Thank you for the link!

Amy SloanOh what a sweet idea! I love it. ❤
