After a cursory search of the forums, I didn't find anything, so I apologize if I missed it...
We all know that we're supposed to be situationally aware at all times. I didn't grow up learning about this stuff, and decided to teach my daughter early. Obviously, I don't want to make her a paranoid nutjob, so we play "the observation game." When we're driving around, I'll ask her questions about buildings we've passed(after she closes her eyes), the color of a car, that sort of thing. Occasionally I'll ask her about people we pass in the mall(physical description stuff), or storefronts. She asks me about things we see as well, and we have some fun with it.
Does anybody else make nonthreatening games out of that kind of thing with their kids? Is there a better way to crack the nut of teaching kids to be aware of their surroundings with out freaking them out?
