This is a very fun game that children love to play. The students make a circle. In the middle, you put some cards with objects in them (you can use the bingo call out cards). The teacher starts describing one, and the children have to guess which item it is. You can vary the difficulty of the description depending on the level of the children.
If you are using this with secondary students or adults, the person who guesses the object can describe the next one.
