Thanks Minnie,
I looked briefly at the first link and it looks really good. But I was hoping to purchase texts. I must be ridiculously old-fashoned, but I like to have a permanent hardcover reference. I like to be able to see what I've done and what's coming next. Obviously I could just print out the pages and put them in a binder, but somehow it's not the same.
I've heard of Singapore math before, but I didn't see a lot of concrete info on the site. I'd like to be able to preview a couple of pages.
When i was a kid we had Holt texts that would intro a small topic and then have 1 - 2 pages of problems that used it. Then a refinement or extension or new topic would follow, and another page or two of problems where it was applied. IOW, the explanation and all the practice needed for mastery in one place. In one book for each grade level. Something about this organization of material is very appealing to me.
