I've tried sooo many maths. I even tried Singapore for my older two this year, but quit after 2 weeks. Can't remember why, lol. But now I have the chance to start my 3rd child off in Singapore right from the start. Should I do it? My oldest does MUS as she needs absolute mastery before moving on. My next is a math whiz and does McRuffy's. I think it's advanced and moves quick. My 3rd child isn't interested and didn't finish her K, actually, she barely started it. So, I'd have to have her do K and be 'behind' before she even really got started. I know that Singapore doesn't start 1st til 7, so I don't feel bad having her do K at 5.5.
Ugh...IDK...can't decide.
Is there certain kids who should or should not do Singapore? Should she (and I

) be able to get it if we start right off with K and the lessons from LHFHG?
Is it a complete curriculum? I'm always afraid my kids are missing something. I really feel my oldest will with MUS, but I see no other choice for her but a mastery program.
