Students choose a metaphor or expression and give three definitions of the meaning, two fake and one true. This exercise is an enriching vocabulary task. First, distribute one or two metaphors per student to research the meaning for homework. Alternatively, give students free rein to find their own metaphors or expressions.

In class, students listen to the definitions and decide which the true one is. Once students have heard all three definitions, have everyone stand at their desks and listen as the descriptions are read out again, and this time students sit down if they believe one is false and stand if they think it true. You can then easily see who is correct, and those students can award themselves a point. Ideally, give the preparation task as homework so as not to use class time for the research. Note you may also do two fake answers and one true one for variety.
