Connect what is seen to real life. Praise their ideas. TV's world is not real. Let them in on some of the illusions. Tell them that white glue poses as milk in cereal commercials.
TV teaches that some people are more important than others.
Point out the predominance of white male perspectives compared to those of women and minorities. Keep track of what people are shown as victims or losers. TV keeps doing the same thing over and over. Make a game out of counting the camera shots in a car chase scene. Check out the music changes during an action climax.
