Here are some worksheets I've modified and/or created for teaching critical thinking and analysis of the media. If you'd like more details on my unit, please let me know! I'm doing this unit w/ 6th grade, but it can be modified for any middle school grade.
In addition to these two lessons, I also did a print media analysis lesson where they had magazine ads at their tables and answered Q's about them orally, both as a whole group and in partners.
Hi! I mentioned above that I'd modified these worksheets but didn't say where I got the originals from! So sorry about that. I modified the TV analysis from http://www.frankwbaker.com/toyadanalysisworksheet.htm and got the basic "skeleton" ideas for the web analysis sheet from Cable in the Classroom's series on teaching media deconstruction.
