Like Ben and aeh, we didn't use the guides, only the textbooks and the accompanying levels' "Challenging Word Problems" workbooks. We used the Primary Maths US edition.
I really, really love Singapore math's approach. No way would I switch it up for Common Core.
Oh-- and if you buy from another source, be very sure that what you are buying is Singapore Math. There are a lot of look-alike and knock-off products in the homeschool marketplace, and this particular trademark isn't really well-protected. I've seen some of those knock-offs, and most are not at the same pedagogical standard.
