bcrowell asks: "As a geek, I always assumed my interest in math and science would just naturally rub off on my kids, and sure enough, my older daughter kept insisting that she wanted to be a physics teacher like me when she grew up. Now, starting first grade, she volunteers that math is 'ok,' but not as much fun as reading, and she no longer wants to be a physics teacher. Her math work at school apparently consists of 'addition packets.' What good stuff can I do to help her perceive math as fun and creative? Generations past had puzzles by Sam Lloyd. I learned a lot of science from science fiction books, but my old favorites are getting dated, and my daughter also rejects them because they have male protagonists -- she prefers Nancy Drew, although she'll read my Fantastic Four comics if Sue has a big enough part. What other things have Slashdotters found to do with their kids? Growing crystals? Baking together as a way to sneak in fractions?"
