I can't recommend go highly enough. Not only are the rules simple enough for kids (mine are 5-9), but counting the score is directly mathematical (counting for the little ones, multiplication and addition for the older ones). the key to go for kids is a small board. 9x9 to start, then 13x13. none of them has graduated to 19x19 yet.
