When I volunteered to assistant teach at a Broadway dance camp for 5-9 year olds, I didn't realize how exhausting it would be! I'm only there from 8:45-12:30, too. They're in four of approximately 5-8 kids groups for the week. There are three teachers, six assistants, and about 27 kids.
During dance classes , they're combined in to two groups by age; 5 and 6 year olds in one group, 7-9s in the other with two or three assistants and one or two teachers leading each class. For about the first half hour of the day they color or do some other dance related craft in their groups with one or two assistants watching them while the teachers set up for the day.
Then, they split in to their two big groups and go to ballet class with the main ballet teacher. Her daughter (one of the other teachers) works on choreography for the parents' showcase at the end of the week with one group while the main ballet teacher leads barre and center exercises for the other. Then they switch. The kids have a break after that to do another craft, usually a prop for one of their dances (wash rags for "It's A Hard Knock Life" from Annie, masks for "Masquerade" from Phantom of the Opera, crowns for "I Just Can't Wait To Be King" from The Lion King, etc.).
After they finish their craft, they go to their next class, either jazz or tap. Then they have a snack and watch part of a video of a musical (Cats and Hairspray are very popular with this age group. I think they just like the idea of dancing kitties and Zac Efron.) and go to the one class that they haven't already had that day.
There are gonna be some SERIOUSLY cute dances in this showcase. Tomorrow they run dances all day and we try to get them to remember them so they only have to have one or two assistants onstage with them, but that might not happen. These kids just can't seem to remember that they run in on the "Ooh"s at the beginning of "Nicest Kids In Town" and not the very beginning. Oh well, they'll still look cute.
