If not, he needs to work on showing what he knows- a whole different problem than not paying attention. You may need to teach him when is OK to do his own thing and when is not, and maybe the teacher can help him with that.
MON,
This is great advice for parents of kids who can handle what you suggest, but I would like to point out that my own HG+ child, at age of 8, 2nd grade, had the normal emotional intelligence, and couldn't have done as you suggest. Each child deserves to be taught at their own 'readiness level.' Certainly 'getting along' is a lesson that needs to be taught at some point, but a stressed out 2nd grader is not ready for 6 hours a day of that lesson.
Now - how to do it.
1) Request a meeting to sit down with the teacher and show her the IQ tests and samples of work that he has done at home with you at his 'readiness level.' Explain that as long as your son isn't interrupting the classroom, you want her to stop asking him to do work that isn't 'mental-age appropriate.' Tell her that you don't care if he does or doesn't learn to color. Get her to agree to what is essential, and see if she is willing, for the time being, to let him entertain himself during the day. Follow up with an email restating what the 'minimum expectations' that were agreed to.
2)Set up a meeting with the school's gifted coordinator, or principle if there isn't one, and show them the work samples and IQ test. Ask them to work with you a way for your child to be faced with learning that is at his readiness level at least half of his day. This is meant to generate a trial plan, and you will all need to monitor and make further changes based on how your son reacts.
3) Look around at homeschooling resources and alternative schools. Prepare yourself to meet more people who say: 'First he has to demonstrate that he is willing to do what his agemates are doing,' and have alternatives ready if you get no where with the school.
4) Call your tester and explain what is going on and ask for advice.
5) Keep in touch with us. We are full of ideas. You are not the only one who has been down this path.
Love and more Love,
