here is my hobbies lesson (PPT). after the presentation i had the students work in groups to create a university club. after each group finished i had them present their club to the class then walk around and join at least one other club, stating why they wanted to join that club.
it was really fun. i got a ton of "sexy boys" club, with reasons like, "i am handsome" etc. i'm at all boys high school grade one, btw.
