Some dances are done alone, but many dances are done together.
When you dance with a partner, one person leads and the other follows.
The leader decides which move comes next.
The follower watches carefully and copies each move.
In a team dance, everyone must move at the same time.
If one person is late, the whole dance looks wrong.
Dancing together teaches you to work as a team — a skill you can use everywhere in life!
