Well, it's not calculus without algebra, exactly. Algebra is one of the math areas we would deal with along the way. But even that won't focus so much on the how to do it as the broad concepts.

I know I'm not explaining this at all well... *sigh*

I think you are thinking about it as traditional teaching, and it just plain isn't! I wish I had a better way to explain it, but it's teaching the broad concepts using physics so the young kids (like DS6) see calc in action, *not* teaching the equations. Does that make more sense?

Think about it as getting your feet wet, not diving into equations and how-tos right off the bat. It's about seeing calculus (or algebra or geometry) as a way of solving real problems, not about getting everything about each branch of math at age 6.

Am I making it better or worse?
