We have a couple of games from

We have Round Up and Caves & Claws. My oldest is 7, he really likes them. They're cooperative games; one of the things I like about them is that since you're not trying to win against someone else, you can easily play a solitaire version.
We were given Cranium Balloon Lagoon for Christmas, and just played it today. The kids enjoyed it a lot. They also like making up board games -- I saw a board game making kit at, hmmmm, it was Chapters.

The kid versions on Yahtzee are fun, too, or just regular Yahtzee... not so much a board game, though.
