Not surprising, I am doing a presentation on dynamic mathematics with Sketchpad .

Being on the vendor end of things, that is virtually impossible since I spend most of my time at the booth.  Though - the beauty of the booth is I get to play with technology all day and meet and show lots of teachers what they can do with dynamic math. Anyway, I know attending these conferences can be overwhelming sometimes, since there are so many choices at any one time so it's hard to know which sessions to try to go to. I myself use to have a daily focus.  The first day I might focus on algebra and technology, so look...
