Dd attends musical theatre classes on a Saturday and they have an hour a week, comprised of singing, dancing and acting. (This class is for ages 3-5 so all pretty basic and they mostly just play games!) The teacher is a qualified actress but not a trained dance teacher.
The children spend some time each week stood in a corner where they take turns to hold their arms out and do some kicks across the room.
Can anyone tell me the benefit and purpose to this? In her ballet classes she does similar with the teacher teaching different skills etc to develop posture and technique but in these lessons it doesn’t seem to do that at all and they spend longer waiting for a turn than actually walking across the room. 
It’s always the same movement and doesn’t seem to develop or progress. In her dance class with her dance teacher you can see visible progression. (I don’t send her to this class for dance, so not worried in that respect( but I guess I just wondered the purpose and if the reason it’s not changing etc is because the teacher isn’t qualified to teach/develop their dance skills. 🙈
