Transparency Markers
Tips for erasing transparencies?

Hello, I just bought an overhead projector for my language classes. Since I'm preparing the same lesson for some groups that I have to delete the notes I write on transparency. Is there a practical way to delete what I write on the transparency? Any special markers? Thank you.

I type up what I want to be permanent and then printed on transparency. Make several copies, and then simply writes a new one for each class – using Vis-a-vis markiers transparency. When finished, these are washable — when I taught in middle school, I always had a bring children to the toilet and rinse them off.
