I'm not suggesting we don't teach kids Math/English, I still think that is important, but the approach we take by shoving kids the same age in the same class doesn't work. Some kids learn faster than others, we shouldn't hold some kids back simply because they are years younger than other kids. If a 7yo is racing through maths and enjoys it, put him with kids of his skill level, when you put a 7yo who is already years ahead in math, with kids his own age learning what he already knows, he messes around out of boredom. Just because a few kids work well in a traditional environment doesn't mean we should hold those kids back, but we do. And likewise slower learning kids who could be exceptional at subjects are rushed through school and declared 'slow' or we blame the parents or homework etc for their lack of apparent intelligence.
