This is a quick-and-easy, 8-slide, ppt with 7 discussion questions concerning cultural diversity. Students are required to say "Je suis d'accord" or "Je ne suis pas d'accord" and give a reason why.
I started this in partners, requiring 3 min. of conversation per topic. After we went through all the questions, students had to stand up, and I'd show each question again. There was a "d'accord" and a "pas d'accord" side of the classroom, and students had to go to the side that fit their opinion. Then I chose one student from each side to share his/her opinion and give an explanation.
