# Pi Day of the Century

## Not for another 100 years!

This Saturday, March 14th marks a pretty cool math concept - the idea of Pi.

Pi, which equals approximately 3.14 is the number you get when you divide the circumference of a circle by its diameter. This is true of ANY and ALL circles and this is what's pretty amazing! Pi is an infinite number and it's first 10 digits equal 3.14926535 We can take this and turn it into an exact day and time this month - March 14th, 2015, 9:26 am (or pm for you night owls). This won't happen again for another 100 years!

So what's the low down?

It's time to get your PI(e) ON!!
Bring your favorite kind of pie - homemade, bakery made, store bought.... to share with your colleagues this Friday ( or "PIE"-day). We'll share our pies in the lounge and take some time to enjoy our favorites and each other!

## Okay - So I like Pie, but what about TEACHING it?

There are a HUGE number of resources available to help your students PreK - 5th grade explore the idea of Pi. From the simple idea of shapes, circles and semi circles, all the way to measuring circles and finding their actual circumference and diameters. What about the arts - you say? Yep! Those are in there too! Take a look at the links below for LOTS of fantastic, EASY ways to involve your classes this week!

Read About Pi with this fantastic story. Students are introduced to the idea of Pi through an engaging tale involving dragons, magic potions, and of course pie!
