I consider myself lucky that 5 yo dd has a really good kindergarten teacher and is doing an awesome job challenging her with her reading and dd has improved immensley. Math, however, is another story and I wish she would differentiate but her belief is not to advance in math for fear there may be gaps that could become a problem later on. She has taught before in 4th and 5th grades where this was a problem apparently. So we are just supplementing math at home for now. Next year we may request that she goes to 2nd grade for math.
