For math, we use RightStart and love it.
We use AAS for spelling, and I don't really find it teacher-intensive. It is scripted, but the part I struggle with is all the rules. I'm a natural speller, it's always been easy for me. Dd 8 yrs is not, and while she does "get" the rules in AAS, she has a difficult time applying them when writing outside of our spelling time. I keep struggling with whether this is normal and I should just keep helping her along, or whether this just isn't the program for her and we should switch. Anyway, that's just my experience with it.
