It doesn't sound like he should be in school.
Simple fact is a child in Kindergarten isn't going to learn anything other than ABCs how to count to 10, colors and shapes... The schools have no desire to put forth effort to teach kids at that age, they are really just mass baby sitting centers. If your child wants to learn home school them instead of Kindergarten. My kids went to Kindergarten because they wanted to be around other kids, not because they expected to learn anything.
Before the first day we explained that Kindergarten wasn't really school it was just organized playtime. We taught them when they were home from school, and it worked well that way... but if they had expected to learn in school they would have been very upset with the reality of it.
I suggest you home school.
