What's important to the anachronistic readers?
I think the best thing you can do for any kid is talk to them - Respect their opinions but draw them out and teach them to think. When they ask "why," about something, fire it back at them. "Why do you think?"
Look stuff up together, play with words and laugh
Teach them critical literacy - to question - to understand that everything is posed from 1 persons perspective - teach them to find that perspective - WIIFM (whats in it for me) is a good tool.
Have fun with cognitive dissonance, and higher order thinking skills eg: what are all the bad things about an umbrella and how would you fix them? What would be the down side of living in an entirely environmentally free world?
Help them recognize that every person has a job - and that, as kids, their job is to learn how to be the best person they can be - one day at a time.
Have fun, but don't lie, and try to avoid putting off answers until "they're a bit older" (although sometimes you might have to!)
