3 Changes

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!
