I diddo the amazing comment!

How about board games? Checkers, chess, monopoly-they have so many versions now. cards games. One thing my girls loved is that talking model of the planets and the sun, has over 600 facts,with questions and answers.

onthegomom is right about the simple things too, I call it getting back to the basics. DD's do this alot they'll do some intense science experiment and then go play paper dolls

Have fun!
