It's Too Loud in Here! Teamwork in the Classroom

I read the previous comment I think the lesson is wonderful, and I will definitely use it. I would definitely number off a different way. In the 70's, we were always numbered off and lined up by size, and I was always at the end. I swore that I would never do that to my students. Teachers could number off in a variety of other ways.

Unless the point of the activity is to teach about pluralism or racism, I don't see where breaking up groups by size is anything but negative. It would be better to have each student pick a card or to use some other random indicator so that students get that the lesson isn't trying to say that tall people make better "x" 's while short people make better "y"s. Because if you break up the group by size, that will be the main idea that is taught, whether its your goal or not.
