There might be places that allow you to do that.
I put my younger son 6 months ago in Mathnasium (he's in our local, excellent public school) since our public school has changed their math textbook and curriculum three times in 6 years. The teacher admitted that she doesn't understand Common Core math, and I didn't think my son was getting a lot of teaching in math.
For whatever it's worth, he goes 3, one-hour periods a week there and does math sheets. The tutors are all college students or above and are probably better at teaching math than the regular teacher.
So he's getting roughly 150 hours of extra math teaching and practice yearly, which is probably more math than he does the whole school year!
