Designate a person to be the leader.
Have a student stand up and take both hands from one side of their body, over their head to the other side of their body to create the "Wave".
This is one part of the wave. Each student will continue to do this until all have "Waved"
The leader must make sure everyone knows the order.
The leader should start the "Wave" as well as direct it.
Tell the class that they will need to work together to pass your (the teacher's) satisfaction.
It works on all the elements that we like in a Brain Break:
Crossing the mid-line, standing up, teamwork, and of course movement.
Happy Brain Breaks!
