Thanks, DeHe and geofizz. I agree with the idea of not wanting to pile on extra work--I've already conceptually fought that fight with people who think it's OK that she's bored for 6-1/2 hours a day at school and then gets to come home and be "enriched" instead of being a kid. I like the idea of surreptitiously building mathematical thinking. I'm going to check some of those media out!
