With the kindergarteners I was doing an observation activity where two people look at each other for a bit, then both players turn their backs to each other and make three changes in their appearance. Then they turn around and try to discover the changes. I was first to demonstrate how to play:
MR. BOWERS: OK, now, you turn your back while I make my 3 changes.
KIAN: I hope he doesn't take off his pants!
