Some of the comments here are addressing the wrong problem. For example the idea of "what to do with the kids while the parents attend".

it's an important question, to be sure.... but it's stage- 2: after you've already attracted the parents, how to keep the kids entertained so the parents can attend.

You still need stage 1: how to actually attract the parents in the first place.

I am a mid-30s female who is getting ready to have kids in the not-too-distant future. I also have lots of friends who already have kids. I am in just inside your target demographic, so let me tell you what I'd like to get out of LW WRT my age-group and family aspirations. FWIW

There's a hell of a lot of stuff here on the site for me personally, ie how do I, personally change myself to become more rational.

The thing that's missing for parents, is how to educate their kids into rationality.

The articles on this site are way too high level for young kids. I'd estimate you'd need a teenager - or extremely smart tween, to read any of them... and not every kid will match this profile.

Simply dumbing it down may be part of the answer... but there's also the aspect of when kids are ready to learn certain "lessons" in rationality. Kids go through extremely irrational early-learning stages, eg its tough to get a three-four year old to even realise that other people don't have access to the same knowledge that they have (remember that experiment where a kid is shown what's in a box and is asked what the other kid thinks is in the box?).

What I'd like as a future parent... are some/any ideas for age-graded lessons I can teach my (potential) kids that will get them up to a higher rationality-level quicker than I did.

If we have these available - that will, hopefully, attract the kinds of parents that want their kids to have the best chance in life (ie most parents). Specifically you can probably attract the same kind of "parent-demographic' that currently goes for "make your baby smart" accessories.

I've been trying to think about what I can contribute myself, in this area... but hitting the fact that I myself am still very much still learning this stuff myself. While I have been putting together some ideas on how to teach the basics of chemistry in the kitchen... I have yet to figure out ways to teach the basics of rationality.

One start was a challenge-article written a while back here: http://lesswrong.com/lw/3c/rationalist_storybooks_a_challenge/

Challenging us to write a rationalist storybook for kids. I think I love that idea... we need more like this.

But even if you can't think up stories yourself, I'd love contributions to these two questions:

1) what are the most fundamental, necessary basics on which to build?

2) how can we write these in the simplest possible way (without adult language or assumed understanding)?
