Sounds exactly like my DD too! (just turned 7!) But I have found that if she learns the next level up, then the lower level of math makes sense to her and suddenly it clicks. I don't really understand how she learns, but it's not in an orderly fashion.
This makes me think of my DS4, who also does not learn in an orderly fashion. He grasps simple addition and subtraction, but HATES counting (says it's boring) and will still sometimes forget what comes after 9 or 11. He also reads at around a 3rd grade level but still can't say the alphabet all the way through. I'm wondering if there's some connection. I think the problem might be that rote memorization doesn't have any meaning for him.
