BS....the more time that partents spend with their children reading and working on annunciation and spelling the more successful readers their children will be. Teach them to spell, decode phonetics, and site recognition by rote, will enable the child to grasp words and improve comrehension and retention.
Ditto, math. Repetition, and number facts. 2+2= 4...it's a simple fact that once, the concept has been understood, it needs to be done by rote afterwards.
