## Welcome to PI Day!

What is Pi?

Pi is the sixteen letter of the Greek alphabet, and it’s also a symbol used to describe the ratio of the circumference of a circle to its diameter, meaning that

So, the number “pi” begins with the numbers 3.14159265, and goes on and on infinitely (so we think). Computers have been cranking away at the number for a while now, trying to figure out just how big it is (and if it will ever stop), and according to Number World, the number has been computed up to 10 trillion digits. Wow!

Pi is the sixteen letter of the Greek alphabet, and it’s also a symbol used to describe the ratio of the circumference of a circle to its diameter, meaning that

*pi*equals the circumference divided by the diameter (π = c/d). The interesting this about pi is that mathematicians who have been working on this number believe that it is infinite, meaning that it’s not the quotient of two integers. In other words, the number pi goes on and on and on, and we don’t know where it ends!So, the number “pi” begins with the numbers 3.14159265, and goes on and on infinitely (so we think).

Pi Day 2015

To celebrate this special number, every year math enthusiasts around the world celebrate Pi Day on March 14, or 3-14, in honor of the first three digits of Pi. The next two digits, following the 3.14, are 15, making this a banner year for Pi that won’t be revisited for another 100 years: 3.14.15, or 3.1415. Yay for Pi!

My 6-year old is fascinated by math and has been talking up a storm about Pi for a while now, so I asked her to help me come up with an idea to celebrate Pi Day 2015. After a bit of brainstorming, she came up with this fun drawing prompt that uses the first five digits of Pi.
