One child is chosen to play Simon. They call out orders to the other children such as: Simon says hop on one foot, Simon says clap your hands, Simon says touch your toes. The children are told to obey each order prefaced with 'Simon says' and not to respond to any other orders.
At random points 'Simon' barks out orders without saying Simon says first and any children who respond are out. They may then help Simon spot those who are out subsequently.
