Instead of just learning actions when they first came into contact, they followed the teacher. Now they will listen to music and do actions, and they will try to make up their own actions. The fun and coordination are obviously improved.

What kind of cooperation form should be adopted in the new teaching, what kind of cooperation mode should be adopted in the review class, and the teaching mode of cooperation and exchange should be selected in a targeted manner.
