I do and do not agree with you. Depending on what do you mean by number sense.
I do not know exactly what this girl knows about the number. If she only memorized those facts without any understanding in number, you are right. But some people just develop their practical sense later than their math sense, some never do.
Two examples: (1) I know a great mathematician who is very poor at applying math to solve simple practical problem like how many rabbits and chicken in a cage with given total number of legs and total number of rabbits and chicken together, but complicated topology in his mind is as easy as we count the dots 1,2,3,4,5.... (2) I have a classmate in junior high who tested greatly in abstract concept and very poorly in word problem solving. His practical sense suddenly exploded in high school and he ended up became a very successful engineer.
I do think that we should teach kids both, but to say what is far more important, I think it is not fair. I don't think learning those fact will have any bad influence on her ability to develop the "pratical number sense". Think of this, if without learning those fact, she might be thinking she is born to be bad in mathematics. You might have a very talented kid in your hand.
