Math sites

Annmarie, I thought of you when I found this site.  This is a geometry site that would be a great challenge for your classes.  It is a game where you have to solve geometry problems to advance through the pyramid and avoid Ammit and other creatures.  Check it out, it's fun!   http://www.mangahigh.com/en_us/games/pyramidpanic

Another great resource for math is Illuminations. http://illuminations.nctm.org/  If you have not seen this site, you should really take a look.  There are activities galore from simple to advanced math, as well as  lessons, and other weblinks.  This is a partner site to Thinkfinity. (see Feb 4 blog post) 

Another partner of Thinkfinity is NLVM which is chock full of activities, divided up by age level and math topic.  I have used this often in the computer lab.  http://nlvm.usu.edu/ 

These are just a few really good math sites, all FULL of wonderful interactives that you can demonstrate at your board, or have the kids work on in the lab or classroom computer center.
