You make a mathcast by going on Screenr and pressing the record button. Next, you pull up paint on your computer and have your tablet ready. you move the screen on screenr to fit into the paint window. you write out your problem on paint with your tablet and solve. when you are done, you press publish and done and then write a description of the mathcast with a hashtag for twitter.
your mathcast is posted on twitter and you are done!

I liked mathcasts because you really had to understand the math concept you were assigned in order to make one. They were useful because I had to make sure i fully understood the concept and problem. I think that they were fun to make, but i hated listening to the sound of my own voice!
I definitely think that we should keep making mathcasts in math!
