Each learner has limited information which the other needs. They must ask each other questions to get the information. To be more communicative, the answers should have some degree of ambiguity that needs to be cleared up with more questions. For example, both learners receive a drawing of a group of people. Each has the names of half of the people labeled on the picture, and the rest of the names in a list. They describe their pictures and ask questions to match names with the unknown people. "Is Sally holding a coffee cup?" may need to be followed by "Is she tall or short?" if there are two women holding coffee cups. Information gaps can be done with street maps, telling time, daily schedule, job interview, spelling, etc. Look for those that encourage interactive questioning rather than mere reporting of easy information. Make sure the students don't show each other their worksheets to give away the answers.
