Let us say that there are 7 students in the class. On 7 chairs.
Every chair is allocated a word from a vocabulary set and the words must be remembered from memory. (person in charge can have a map)
Person in charge instructs students what to do by using the names of the chairs they are sitting on.
e.g. with colours - blue change places with green / pink stand up / orange jump up and down.
Spice it up by changing the names of the chairs after a while or adding more chairs.
Elimination could be a factor for the last person to a chair or anyone who moves out of turn.
If it is going get competitive I say touching or pushing is an elimination offence so therefore eliminating the threat of violence that hangs over this game.
