A little background: I'm a preschool teacher who also does parent or teacher workshops for a local tv station. They are usually literacy-based and the focus is early childhood. Now I have one where the focus is elementary math. (which I have not done since student teaching, 10 years ago!) The "script" I received (for a teacher workshop) tells me to teach Venn Diagrams and estimating/graphing jelly beans. Teachers KNOW this already! So I'm going to go in there armed with a bunch of fun classroom activities to share with the teachers. ANY help, suggestions, or ideas would be great! I have a week and half to prepare.
