I was just now working on my presentation for the [Joint Mathematics Meetings in January][1], and put together links to some blogs that have great resources.

Check out:

 - [Bowman in Arabia][2]
 - [ThinkThankThunk][3] (I'd love to try the [rolling chair races][4].)
 - [Sam Shah's Blog][5] 
 - [Math Teacher Mambo][6]  (Link is to one project. Search on calculus for more.) 
 - [Math Mama Writes][6] (This is my blog. Link is to optimization project. [I also recommend this][7].)
