I love watching kids think. For one, the expressions that wash over our faces when we’re puzzling something out are kind of hilarious. Look up, down, cock the head to one side, frown, open the mouth slightly, then suddenly they dive back down towards their paper.
The best is the “checking my answers” dance. That student that is done with a quiz/test, and on the way to turning it in, they slowly waltz through the room as they look over their answers. You can almost hear the ba – bup – bup slowly fading in.
