Looking around my email last night, I found this note I had left for myself:

"yrs ago I fell in love w math doodles as art http://is.gd/99NmA Now I have student posting hers http://is.gd/99Nww."

 I had email this to myself and had no idea why - it's been a while.  I clicked the links  (they resolve to http://artofstaceykite.com/mathframeset.html and Mr. Morris' math class at http://discovery.caryacademy.org/michellew775/ if you don't want to use the shortened URLs) and was seriously impressed.

 I'll let you click through and see what they are doing with Math and OneNote, and believe me, it is worth the click.  All I will say is "amazing!"

Questions, comments, concerns and criticisms always welcome,
John
