My younger kids are also in Singapore Math, as well as other things. wink I also have the Holt courses mentioned and some of the Lial's books.

I really like Singapore for the younger grades as well, if you click on the book you are looking it and click samples you can look at a few of the pages. The placement tests also give you a good idea. I would suggest the Challenging Word Problems and the Home Instructor's Guides, they really round out the program.
