Mk13, I am not going to be able to offer any useful suggestions but wanted to let you know that my dd4.5 is similar. She is much better at math facts when she is jumping and twirling at the same time. Also, when solving the math fact is part of solving a bigger, more complex problem, she can do it much faster. It is as if she is then able to pull the data stored in her brain without having to think. So ask her how many apples if she eats 3 apples a day for a week, no problem. Ask her 7 plus 7, takes time. Go figure! At this age, like you mentioned, these kids are ahead of age peers so why bore them with something they have no interest in proving their mastery over. Instead, all I want for now is for her to continue to love math and figure things out. The rest will follow in due course.
