This one is great for over excited Students who need to burn off a bit of energy.

It's also good for classroom commands and numbers.

Stand the students in a line and call out instructions:

"Jump 10 times"
"Turn around 4 times"
etc.

Other good ones to use are:

hop
hands up & down
touch your (body part)
