I taught kindergarten and first grade for 5 years before becoming a SAHM and I have to say they DO expect WAY TOO MUCH from 5-7 year olds. First grade was very academic and seemed almost like 2nd grade, while kindergarten was losing centers (housekeeping, blocks, etc) and becoming like a mini first grade. When I was in kindergarten I remember PLAYING the entire time I was there. I think those in charge of creating curriculum (which I have to say from my own experience, was made up of individuals who have never taught in a classroom) forget the learning through play is so important at this age.
