In this PPP, you'll find some statements related to movies. Students take sides and offer reasons to explain their point of view.
I like to ask my students to literally take sides; so I say "if you agree with this statement, stand on my right. If you disagree, stand on my left." In this way, they can see who think differently face to face and the conversation gets more interesting because they try to convince their "oppoents" by explainng their point of view. When I change the statement, they can change places depending on their opinion.
