Easy as Pi Day!

Happy Pi Day tomorrow everyone! Whoo!! 3.14159 26535...yadda, yadda, yadda out to several thousand, millions really, and beyond... Pi doesn't end. It just doesn't. It keeps going and the digits do not repeat in any kind of pattern.

Wait, what? Yes, you heard me.

It just seems random and arbitrary, but pi is not. It is exact and applies to all circles regardless of size.

If you multiply the diameter of a circle by pi, you will get the measurement of the circumference. There is a constant relationship between the diameter and the circumference of every circle and it is expressed by pi. If you take nearly 3.1459, or pi, diameters of any circle, you will get its circumference. Amazing.

I can't teach my kids about how mathematicians go about finding the digits of pi--must look into that. However, I do have a great series of story math books, that explain some math concepts including pi.

Tomorrow we will again read, Sir Cumference and the Dragon of Pi, where Sir Cumference's son, Radius, will save him using math!! His mother, Di of Ameter shows up sometimes too. These Sir Cumference books are a kick. The stories are set in Medieval England and feature castles and dragons and knights all the while demonstrating different math concepts.

So, we'll read that book and then we will make pie to celebrate pi! Chocolate pie to be exact. My kids don't know about that and will flip when they do find out. Shhh. Don't tell.

Happy Pi Day this March 14th, that's 3/14--get it? 3.14. See?

Go get some pie and celebrate.

That's good pi.
