I was looking at the Singapore Math website and it seems they have different versions of their math. What version is used with HOD? Is it the US version, newer CA Standards version or the original Singapore version?
Also, many reviewers (on another site, including a reviewer from Singapore) say that additional review is necessary in using this program. Is there review built into HOD's guides or do we need to purchase our own review work separately?
I haven't used Singapore yet, just reading the reviews and trying to plan ahead because I have an almost 4th grader that might be "jumping into" Singapore and I want to be prepared!
(Maybe prepared to a fault!)God bless, Michelle
