Cool blogs

At Dave TarH2O's suggestion, I check out let's play math blog which has a good post about writing to learn math http://letsplaymath.wordpress.com/2007/08/21/writing-to-learn-math/. There are great links on this post of was to get students reflective about math by writing.
I also came across another cool math blog called Math Notations with a good post for Alg 9A teachers http://mathnotations.blogspot.com/2007/08/mean-median-of-arithmetic-sequences-on.html.
Also I found a site that can accomodate equations in blogs. Check out http://texify.com/
Happy blogging
