Your DD is only 6, so she is still really young. You have lots of time work on math facts. Although I think it is boring, buying a few Kumon books and drilling through those are really good for math facts. And just buy or make some flashcards and flip through them daily, 5 minutes a day.
We did that for my older one, who has a processing disorder. We did flashcards (addition, subtraction, multiplication) 5 minutes a day for 6-12 months.
I had him do a few speed math tests- he got 49/50 for addition and subtraction and 45/50 for multiplication in two minutes. Not too bad! 1 1/2 years ago, he only got 14 in 2 minutes. So just chip away at it.
