This is another game which will feature prominently in my upcoming article in EtP magazine on getting students to use more complex language. Students are given a pack of cards with key words for one or more functions on them, e.g. cards which say “interrupt”, “where”, “finish” etc for turn taking. Perhaps after brainstorming suitable phrases using those words, students try to use as many of them as they can during a speaking activity. The person who uses the most cards is the winner.
After playing, students can brainstorm phrases (if they didn’t do that before), try to remember the phrases, or, in the top variation below, put them together to form collocations which could make such phrases. Alternatively, there’s the variation in the bottom two examples below, where brainstorming is the whole activity.
