I can see from the length of your post how frustrated you are. There is no doubt that 6 year old boys can be a force of nature. I was always in awe of my kindergarten/first grade teachers for their ability to work with the little guys. And, a bit more information really is needed for accurate help. But, I can understand given the length of your post, why you didn't get everything in.
While I agree with Mark about his comments on discipline. I am not necessarily sure that this is classic misbehavior. For example, sleep problems can seriously impact a child's behavior, and will cause many of the things that are bothering you.
"There is increasing evidence that sleep problems can have a negative effect on children's cognitive, behavioral, and emotional functioning. Dahl (1998) asserts that the rising rates of behavioral and emotional problems in children can be associated with sleep problems. Most young children do not have typical symptoms of sleep loss such as yawning or obvious sleepiness that are observed in adolescents and adults. Rather, children often manifest symptoms that are paradoxical to sleepiness such as irritability, hyperactivity, short attention span, and low tolerance for frustration (Dahl, 1996). From the link given below.
If his problems are due to his sleep habits, then discipline is not going to be as effective until the sleep problems are dealt with. Here is a very inclusive link to sleep problems.
One of the other things to think about is the possibility of ADHD.
"Children diagnosed with ADHD have been shown to have a higher incidence of sleep problems and shorter average sleep duration than children without ADHD (Owens, Maxim, Nobile, McGuinn, & Msall, 2000). From the same article above.
And here is another shorter article on sleep problems in children with ADHD - http://www.sciencedaily.com/releases/2008/04/080407160751.htm
I mention this due to some of the symptoms you mentioned. His anxiety about school, his daydreaming in class, handing in blank papers, etc. are certainly symptomatic. I am also the CL for the ADHD forum - http://www.medhelp.org/forums/ADD---ADHD/show/175
- and do see certain definite signs. And, of course, punishing a child with ADHD is done very differently then a child who is just misbehaving. However, here again, the sleep problems might be the cause.
I really need a bit more information. It sounds like they are in Kindergarten still? If so, I would suspect that they are among the older children in the class. And, if so, he should be doing well in class due to his age and innate intelligence. The question is - what is his concentration like? Does he need to get directions repeated all the time. Can he get things done on time (even when he knows the material)? Is he impulsive? Maybe pushes other kids without thinking, etc.
From my own experience in working with ADHD kids - frustration - was always a big signal to me that something was going on. A long with that comes anxiety.
Anyway, you may want to read this link on ADHD. While I have many links I can recommed - this is a pretty good place to start.
Get back to me either here or on the ADHD site and let me know what you think.
In the meantime - talk with his pediatrician about his sleep problems. Does he snore at night? His pediatrician might even recommend giving him something like melatonin to help him sleep better.
Dealing with his behavior at home really depends on the causes. Kids do need to learn other ways to express their anger, anxieties, and frustrations. There are several good books aimed at the kindergarten to 7 year old child. These books are meant to be read to them (many times) and practiced (before they get too mad to pay attention) a lot. If you check out these links you will also find other good titles listed below the books.
We can give more behavioral suggestions for discipline, but need to know whats going on with him.
Hope this helps. Do get back to us and tell us how he is doing in school now. Best wishes.
