If it doesn't add to their gymnastic learning I would be mad. Sometimes at DD's riding lessons, they clean gear or stalls....but it's part of a lesson on horse management so I don't have a problem with it. Cleaning a foam pit doesn't add anything to the gymnasts. So if you are paying for her to do it, I can see how you would be angry. A better way to do it would be to have a volunteer "cleaning party" and give a free lesson to everyone that participates.
That is a great ides.
I also don't have a problem with kids working and maintaining, but that needs to be scheduled in. My daughter does tumbling and cheer, they have never once required to to clean equipment for tumbling but at cheer, they have mat duty which consists of the girls rolling our and putting up the mats. THis is scheduled, and they come early and stay late. The coach knows that you shouldn't cut into cheer practice time. These mats are extremely heavy so yes it does provide a little conditioning, but it is done after the instruction, so you still get what you pay for.
