This is an activity I like to use when teaching relative pronouns. It can be adapted to any age group or level just by changing the difficulty of the examples and expectations of the students. The best part is it requires NO materials or preparation and is great when you need to come up with a lesson quickly.
TARGET LANGUAGE: WHO, WHERE, WHICH, THAT
I usually start this lesson by walking into the classroom looking confused. I say to the students, “I FORGOT!” then, “What’s that woman called who teaches math and has three daughters and is really nice?” at which time they’ll name the teacher. Then I’ll shout again, “I FORGOT!” What’s that place called where you can quickly go inside and buy snacks or drinks but it’s not a supermarket?” (mini mart) … again, “I FORGOT!” by the third time they should be shouting “I FORGOT” with you and laughing along at your silliness. Use as many examples as you’d like to get the students excited about the lesson.
