blackcat, I don't know about younger children's groups, but in our area there are quite a few adult groups that are centered around different areas of interest in history, plus lectures on history frequently at our library. I suspect you can continue to find documentaries online or through pbs etc - the key is to not think that you have to be on top of all the learning too - let your child make his own discoveries. If you have a university nearby, with a history department, you could try to find a college student to mentor him outside of school. Or if you have a retirement or assisted living home (or elderly relatives or friends), perhaps they could get him interested in some more recent history (from their youth or from stories they know from their grandparents etc).

I also wouldn't assume that history in school will always be non-interesting for your ds simply because of his higher IQ. The teacher is so key - my kids have had some amazingly wonderful history teachers in middle and high school - teachers who made history come alive which lit their interest in making connections rather than just gobbling in information and facts.

Hang in there!
