Here is a blog to watch. Scientific American is running a guest blog on it’s site by Bob Gruman called mhpoetica. It explores the world of mathematical poetry. Yes, there is a “world”.
Thanks, Jim

Loving Bad Math
I found a great Flickr photo group via Free Tech for Teachers. It is called Bad Maths, and is a place to post pics of the crazy math sometimes sees when shopping. Danny Nicholson, the groups admin, uses it in class as a warmup. There are some really good ones. Definitely worth a few chuckles.

Thanks, Lee, for sending it over.

Mapping Maps to Music
I’m a sucker for any mapping project like this one. The world map is translated into a score for 37 different instruments. Found via Futility Closet.

Math + Gifs
An old student found this listing of all the gifs on Wolfram Mathwold’s site. Pretty cool to browse through.
Thanks, Jay!

Now Playing: Numberphile
I’m loving this Youtube channel, Numberphile. It might be a way to try to bring some media into the classroom in a non-boring way. I hope they’ll get students to wonder about math in a more general non-skills based way.

Word Problems + Headaches
I had a couple of students send this in. I’ve definitely been there myself. Some of the word problems in textbooks really make you wonder (or jump out of a window).
Thanks, Lori and Nilsa

Miura Fold
I came across the Miura Fold on Lifehacker. It basically allows one to fold/unfold something with a single motion. The easiest way to think about the value of the Miura fold is in terms of a map. I can’t count the number of maps I’ve screwed up by not folding it back up the right way. Unfortunately it’s fairly hard to learn the fold. I have to build up those origami skills.
