Socrates-Have you thought about doing independent Critical Thinking skills with your kids? I got some books on Amazon on the subject. My kids LOVE doing them. For younger kids, there are a lot of compare and contrast things, why things are similar and so on. They ones for older kids really make you think and understand and recognize different kinds of statements and situations, i.e., sweeping generalization statements. My teenage son likes to do these more difficult ones, but my middle pre-teen races into the room whenever we do them, because she finds them fascinating. They are able to listen to commercials on TV and radio and see how ridiculous the claims being made are and often they comment on them. It has carried over to what they are hearing at the Hall, they come home and tell me about the incongrueties in the message.
You could tell your wife that you just want to make sure that your kids are aware of crazy advertising claims, and statements made on the internet, so they won't be fooled and will become better consumers. Your wife could even help you to educate your kids to become better consumers. She will learn a lot.
