All activities to review and help students recall lexis are always welcome.
After teaching a set of lexical phrases, for example idioms or some other lexical chunk, get learners to pick one phrase. This will be the title of the 50 word story they are about to write.
Share stories around the room, review them, write comments, choose favourites, rewrite the endings, discuss how appropriate the titles are, etc.
A quick and personal game for consolidating lexical phrases.
