Quoting chotovec82: Yes he teaches them both forms; onety two and twelve. I wouldn't worry about that. My son has started at Primer and is now on Alpha and he knows that onety two is really called twelve. It's helped him a great deal with writing his numbers correctly as well. Just let the program do it's job and you'll see that he'll say 12 when talking to you or others about numbers.

i started wiht alpha, and I thought he only kind of used that as an explaination of how eleven is ten plus one, and twelve is ten plus two, etc. I didn't see it explicitly used in the aplha or beyond workbook anywhere. Also, my sone was 9 when he started Alpha (started there for review and remediation) and had been thru a PS math program, so he pretty much had the grasp of that by that time...

I"ve really liked Alpha, Beta and Gamma and plan to keep buying. I can't think of anything else that he switches around much, at least not in any way that doesn't make a lot of sense. I really like how he does multiplication and gets them used to other ways to notate multiplication (like 8n=32 solve for n, or (4)(2)=8, or 3ā¢4=12, etc) I also really like how he give the option in multiple digit multiplication to not carry up on top to the tens place, but to put the numbers below, and do all the addition at once. That has helped my son alot with organization and not confusing what he's supposed to be multiplying or adding.

I was more hands off and they did the work themselves, so I figured I'd ask them.

I did NOT teach my kids to say it that way. I started my youngest with the Primer, and he's halfway through Alpha, and he knows all his numbers as twelve, thirteen, fourteen, etc. I thought that way was too confusing since he already knew all those numbers before we started with math.
