Regarding spelling, does your child see a word in terms of how many letters it contains in order to help them to account for each?

Our son spells well two years ahead of his grade level, and I have noticed he will sometimes say something like, "Okay, that's an eleven letter word..."; and then spell it out correctly.

I asked him if he sees words in terms of how many letters it contains and he said that if it's a hard word, he does.

DS is two years ahead of his grade in math and I was wondering if this is typical of "mathy" kids to help them in subjects other than math.
