Haha, I never thought about the math & science titles sounding cutesy. GS9 and I like puns and plays on words, most of those titles would get us going!
Overall, I think the math concepts covered were similar to what was introduced in GS9's classroom, but his classroom didn't get in depth as much as Hirsch seems to plan out. GS9 is a couple years ahead, as he's doing pre-algebra at home. I'm not sure where his average classmate would place in Hirsch's plan.

JoAnnQN, I think it would really be troublesome if the federal gov't specified curriculum. That'd be stepping on our rights in a big way. I thought I saw in the linked article about how they were going to specify a standard but let it up the the school on how to teach to the standard.
