There is no need for having these mastered now, esp since she is going to K in Sept. and they will barely be going beyond counting, but it seems to me that it would be nice for her to have them in her pocket so she can do more with numbers.
This seems very common. In fact, she gets less opportunities to learn through drill than other children, so I would drill her! It's nice to have a child who is unusual in ways that schools 'get.' Cold knowledge of Math Facts is a way to speak the schools language, more so than, say, being able to compare two pieces of literature. Math Facts is something that most kids struggle with, and if she has them, they will 'get' that she is advanced.
I would still make a game out of the drill, and keep it fun and short, but I would go daily. I was lucky, in 3rd grade DH drove DS to school each morning, and that's about all they did in the car - drill math facts. DS and I are both still sort of shaky on them. Some families like songs, sometimes it's funny (punny) pictures. On my side of the family, it's card games like 'Casino'
