At the Regional Summer Teacher Academy a few teachers said they were torn between attending my session and another one, so I told them to go ahead and go to the other one and I would make a screencast and help them after school someday if they are still interested/need help.
Here are the screencasts of my session. By the way, this was my first time ever making screencasts. I think this is going to become a great tool for me to share resources with my teachers. I used screenomatic to create these--if I can figure it out, then almost anyone can!
