Select two people to turn the long skipping rope in the middle of the room.
Line everyone else up so that they are ready to run underneath the rope one at a time.
The teacher sets the timer for 2 minutes, and then says “Go.”
One at a time, the students must run underneath the rope without touching it at all. Once they have, they circle carefully around the rope-turners and get back in line.
The teacher counts how many people can pass through the rope gauntlet in 2 minutes without a single person touching the rope at all.
Do as many times as you like, and then write your class’s highest number on the board.
