Singapore Math comes with a semester-long textbook and a workbook for each student. Right now, they're beginning Singapore Math 4A and when they are finished with that, it'll be time for 4B. It will take us a fair while to get through the books because most of it is not busywork. It's teacher-intensive and often needs a bit of explaining and classroom practice to be done well.
Usually I'll teach the concept from the textbook and go over the problems in the text with the children (using my dry erase board and bad drawings), and then allow them to do the workbook exercise on their own.
I'd highly recommend this curriculum for parents who want to actively teach their children each lesson themselves. If you're interested, I've reviewed it in a bit more detail previously when I used it to teach Emperor and Elf.
Wow, that was ages ago...
