• Filling the gaps in a schedule or timetable: Partner A holds an airline timetable with some of the arrival and departure times missing. Partner B has the same timetable but with different blank spaces. The two partners are not permitted to see each other's timetables and must fill in the blanks by asking each other appropriate questions. The features of language that are practiced would include questions beginning with "when" or "at what time." Answers would be limited mostly to time expressions like "at 8:15" or "at ten in the evening."
• Completing the picture: The two partners have similar pictures, each with different missing details, and they cooperate to find all the missing details. In another variation, no items are missing, but similar items differ in appearance. For example, in one picture, a man walking along the street may be wearing an overcoat, while in the other the man is wearing a jacket. The features of grammar and vocabulary that are practiced are determined by the content of the pictures and the items that are missing or different. Differences in the activities depicted lead to practice of different verbs. Differences in number, size, and shape lead to adjective practice. Differing locations would probably be described with prepositional phrases.
