When my son was younger (8-11 or so), this was a regular part of our media diet. Two or three times a month, I would gather print advertisements and we would look at what was being sold, what thing (person, object, idea) was being used to sell it, how the thing was being used, hidden messages the advertiser was using, assumptions of the advertiser, and what form, if any, of discrimination was being used to promote the product. Having used the print media for this purpose, it was easy to use television in the same way.
