Happy PI Day! and a link to a website about PI Day….

Its PI Day again. And not Pumpkin Pie, or Cherry Pie, or Apple Pie…

from the site of http://www.piday.org:

Pi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “π”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159.

Pi has been calculated to over one trillion digits beyond its decimal point. As an irrational and transcendental number, it will continue infinitely without repetition or pattern. While only a handful of digits are needed for typical calculations, Pi’s infinite nature makes it a fun challenge to memorize, and to computationally calculate more and more digits.

 Over at http://www.piday.org they have some neat gifts for the math geek in your life.

They also have some video’s for the history of PI and some other neat info. Check it out and you could put together a little Unit Study for your kiddos.

(make sure you pay attention to the More PI Stuff in the left, the more you click on the more stuff pops up and there is some more fun things)
