Spot the Difference

Divide the group in pairs. For this activity you get two apparently iqual pictures. You can get this pictures in puzzle books or internet. 
Give one of the pictures to a student an the counter-picture to his/her partner. Make the students sit far from his/her partner in order to describe the picture without looking at the counterpicture. The point of the game is to detect the differences without using body language or looking at the partner's counter-picture. The team that finds all the differences first is the winner.

This activity is specially good for those students who are reluctant to speak.
