I've been reading past threads and have been swayed to used Singapore math over Saxon math--sounds like it will work better for my 5 yo son. However, in looking at the publisher's site and at ebay, Singapore math seems much more expensive than I thought it would be (~$112/semester plus $113 for the CD of virtual manipulatives). Is it just that the new "Math In Focus" text is more expensive than past versions? I recall posts from a couple of years ago saying how much less expensive Singapore was than Saxon.
Are there older versions I could use? An ebay search turned up "K1 Math Child Development Program" with books 1-4, which is labeled as Singapore, but I'm not sure it's the same thing as the Singapore math program that's now publishing the 'Math in Focus' books. Any insights? I may end up going back to Saxon just because I'm not sure I'm ready to spend close to $350 for a single year of math materials.
