Your "brighter kids" probably did their reps already, when you weren't watching. My 4 year old likes to quiz me on addition and subtraction at the dinner table -- two years from now, in some school, it'll look like he 'just gets it', which he will, but only because he already did his reps.
Couldn't agree more with you. I have kids of the same ilk. There certainly a differential in children's natural aptitude but they all do reps either publicly or privately - many people just don't realize it e.g. OP.
