I was in a classroom the other day helping with something TOTALLY unrelated to the teachers lesson. As I was working I was listening to the teacher teach math to her 1st graders. She did such an awesome job (I mean I stopped what I was doing to see what she was doing...teaching 1st graders is a rough subgroup for me...control wise). Anyway, we had to test out what I was helping her with (signing 1st graders into our science tech book) and I asked her to repeat this "call back" she used with her students as she modeled how to use the shortcut we set up. I video taped it because it was too cute not to.
I tried it today in a 3rd grade classroom and they picked it up pretty quickly. I would like to say I was as successful as the teacher in the video but alas I failed to model what "watching" looked like first (my mistake).
So, if you are going to use this call back make sure students know and practice what "watching" looks like before introducing it.
