The ballerinas I teach on Saturday mornings like to play games.
This probably isn't news to you since they are 4-5 years old, and I'm pretty sure 99.9% of children in this age group like to play games.
Anyway, one of their favorites happens at the beginning of ballet. We let them all put on a crown, hand them a wand, and tell them to, "go to sleep".
Good night sleepy little ballerinas!
Then, we turn on the music (usually the soundtrack to a Tinkerbell animated flick), and they all "wake up" and prance around showing off their best ballet moves.
