Happy International Pi Day! I’m afraid I don’t have time to write a completely new post, so I’m cribbing from last year’s, since the links are still good. Enjoy.
Today, March 14, 2009, is Pi Day (3/14, get it?). Last year at this time, Unfocused Girl was getting more interested in math lately, and what really got her attention were the big ideas, and π, which embodies so many important math concepts, captured her imagination. Unfocused Girl has even memorized the first 11 digits of π (3.1415926535). In honor of Pi Day, I promised her I would post links to some of her favorite Pi places on the web.
First, what is π (Pi)? Here’s a link to the collective wisdom of the Intertubes at Wikipedia.org.
Here is the official website of Pi Day. Happy Pi Day!
This video has Unfocused Girl’s favorite song: The Pi Song (there are a lot of YouTube vids called “The Pi Song”; this one is her favorite).
She is also fond of The Number Pi Challenge, and Happy Pi Day!!!!!!!!!! There are many, many more, but not all are appropriate for children (that is, I don’t think they’re appropriate for my children; you can make your own decisions).
Update: Unfocused Girl just pointed out that in six years, Pi Day 2015 will be Golden Pi Day, because it will be 3/14/15.
