The students in the third grade of primary school are already very sensible children. I think dancing will affect their mood. I recommend some more modern "national" dances. More meaningful, such as "People Paddle Sail" and "Go Straight", you can watch videos of potatoes or Cool 6. Many dances can be imitated and learned, but the best way is to be taught by a dance teacher with dance qualifications. The professional teaching of dance directly affects the basis of re-learning dance in the future!
