So here are the new, update versions of everything, including answers to the worksheets, and lots of suggestions. I wrote my explanation right into the ppt, in that white box under each slide, and also on the answer page to the handout.
I used until slide 15 in the ppt.
I also discovered that leading the class in discussion was much better than giving the groups 5 minutes to talk on their own and answer the questions (basically it didn't happen!).
Please review the content of this lesson carecully, especially the lady gaga video, to decide if your kids can handle it or not. My classes are all girls and the discussion of the topics went pretty well (besides pretty short basic answers) but they weren't too offended by the material. I'm not sure about mixed classes.
If anyone is wondering, most of the information about the song and bullying came from Wikipedia and was slightly altered to fit the students' language ability.
