Experimenting at School

No, I'm not talking about kids experimenting with drugs.  I'm talking about parents experimenting with different techniques to help their kids at school.

For those of you that don't know my son, he is a very...interesting kid.  He is exuberant and full of life and SUPER smart, but he is also strong-willed and highly emotional and young for his grade.  We decided to let him go ahead into kindergarten because he was already bored his last year in preschool because he already knew half of the stuff they are supposed to learn in kindergarten. So now we are dealing with the disparity between his academic level and his maturity level.

His teacher has already hinted that she thinks he might be ADHD. Now, in all fairness, I have had the thought that it might be a possibility before she ever brought it up.  However, my husband found a website with the checklist of signs that your child might be ADHD and took the test separately.  We both came up with him as not qualifying. I've also talked to several teachers and they said that since he is not having trouble getting his work done and is not having trouble paying attention in all subjects, they don't think he is either.

Here's what I think he IS:
He is an extroverted feeler and the emotional side gets harder for him to hide if he's tired (hence a couple of afternoon meltdowns).
He is high energy and VERY kinesthetic so needs movement and has a hard time being told to sit still.
He is an auditory learner, which I learned means he needs to hear himself say something for it to sink in rather than listening to someone else say it.
He is very smart and gets bored and resentful with repetition (esp if he already knows what is being repeated).
He is strong-willed and will resent and rebel at being told what to do. He is more than happy to work with you if you use "can you do me a favor" or "let's do ___ so we can ___".
He is young for his grade so, while he gets along with his classmates, his attention span and maturity are not as strong as theirs yet.

So, taking all of this into consideration, we are going to try some experiments at school. The goal is to keep his mind and body occupied without boring him or distracting the other students. Here are the ideas we have had so far:
-An exercise ball chair so he can bounce in place at his desk
-A stress ball for him to squish while sitting in group time for sight words
-Fun pencils to visually distract him at his desk
-A clipboard with paper for him to doodle on while he listens sitting in group time
-Have him repeat back instructions or concepts to make sure he's "got it"
-Have the kids make up a story using the sight word(s)
-Make a bingo game with the sight words in the squares
The caveat for any of these is that he has to be paying attention and following the rules with any items he has or they get taken away.  I figure we will try one or two at a time and his teacher can let us know which ones are working and which ones aren't.

If anyone has any other ideas, I would love to hear them! You never know which will be the one that works.
