Information Gap activities are often used in second language classrooms. They are generally designed as partner exercises where one student has to get information from the other — speaking the target language — in order to complete the assignment.
Picture Dictation may be the most popular use of this learning strategy. Each student has a different picture, and they verbally describe the image to their partner, who in turn has to draw it.
There are many other variation, too.
