This game is best played indoors in a hall and you will need benches.

How to play:

Choose about 4 people to be police.
Set out some benches around the area, about 3 feet apart from each othe.

The class have to walk along each bench and get to the next one quickly but carefully. If they are ever on the floor and the bench police see them, they are out. They can get back in if somebody passes them and manages to touch them.

You might need to put out mats and explain the safety rules to the class.
