DRILL: Don't Wake the Dragon

Don't Wake the Dragon. 

Directions: Can gear this towards older age groups by taking away the dragon story bit. The children are villagers in a town under attack by a nasty dragon. To save their village (and themselves), they must line up in order of tallest to shortest … without talking. Once they've completed the task, they can simultaneously say "Boo!" to scare off the dragon.

If you want to make it more difficult, have them line up in Birth order without talking! This will have them using their hands & communicating in other ways.
