DS has been working in a couple of phonics programs (100 EZ lessons and ClicknKids) and we've done some light math work. I've had him do some simple copywork and he's able to do letters, words, and short phrases.
DD knows her colors, shapes, etc. and can do simple addition and tell time by the hour, too. She's learning her letters and their sounds currently but it's not a formal/consistant thing.
So I'm wondering, if I place DS in Beyond (with the 1A/1B math) am I'm cheating him out of anything or hindering him by skipping LHFHG? I feel like some of the program might bore him based on the sample but I don't know if Beyond would be too much, ya know? And there isn't a 1st grade science per se - would that be a problem? Also, narration isn't his strong area. I don't know if it's a comprehension issue or he just doesn't want to or know how to express what has been read. Still trying to figure that one out.

For DD, I'm torn between LHTH age 4-5 and LHFHG kindy level. She seems to be very number oriented and loves being read to. Her comprehension skills amaze me! But she hasn't done much in the way of writing (except a couple of letters like "A" and "X" and "O") and like I said before, there are still some letters & sounds she needs to nail down. I lean towards LHTH but just wanted some opinions.

I'd love any advice you all could offer here. I've looked at all the placement charts and I'm still not sure where to put them.
Thank you!
eta: I had DS do the placement test at the Singapore site for the 1A - He got over 50% correct so I assume that is the right level for him.
