Separate your English class in 2 groups: Group A and Group B

Ask group A members to answer this question:

"If you became invisible, what would you do first?"

Then, ask group B members to answer this question:

"If you can buy anything, what will you buy?"

Variation: You can also ask the students to draw their answers.

Good luck.
Quote: When students don't want to learn anything, teach then what they like.
