Simon Says

This game can be done either in a circle or in a large group gathering.
The group follows the leader’s instructions only if the leader says “Simon Says…” and then an action. If the leader says an action but does not say Simon says, any body doing that action is out.
The leader says "Simon says put your right hand up" while you make the motion yourself. The students put their right hands up.
Then the leader says, "Put your right hands down," any person who puts his/her right hand down must sit because you didn't say, "Simon says..." first.
