I've used this with as many as 180 kids at once.

Children are running through the 'jungle' and run into many animals, etc that they need to get away from. The teacher can give appropriate commands, and the children carry out a suitable action:

• jump over logs
• duck under branches
• high knees through quicksand
• run from the tiger
• tip toe past the snake
• talk to the monkeys (ooh, ooh, aah, aah), etc.

This really gets kids' hearts pumping and they have a blast!
