Bounce Like a... Game
Tell the children that every time you count 1-2-3 then yell out an animal, they have to jump like that animal.
Try frog, kangaroo, rabbit, then see what happens when you call out lizard, bird, elephant, fish and snail!!
The Giggle Game
Have one child lie down in one corner of the moon walk, then have the next child lay down at right angles to the first child with his/her head on the first child's stomach. Have a third child lay down with his/her head on the second child's stomach. Keep on until everyone is lying down. Then have the first child say "HA". This will cause the second child to start laughing then the third, then so on.
You may have played this one before, but not in a moonwalk!
Balloon Fun
Grab some balloons and toss them in the moonwalk with the children. The can bounce with them and toss them in the air.
Tumble Races
Have the children take turns with this one.
Line up 4 children on one side of the moonwalk and when you say "GO" they somersault their way to the other side, touch the wall (or net) and then lie down and roll back to the other side.
Make sure the somersaults are on the floor and NOT in the air.
Red Light/Green Light
When you yell "green light", everyone bounces. When you yell "red light" everyone freezes.
