Bronxmom, I have a DS7 who is very similar. I have finally figured out (after 1-1/2 years) that he is a Discoverer. He does not like to be 'taught' anything! He needs to learn and figure it out on his own, specifically without me in the room. So when I need to 'teach' him something I use pudding. We are working on spelling and cursive and using pudding, whip cream, ice cream, etc. He loves it! We only do <10 mins a day on what I deem important for him to learn. Can u video tape this for documentation? We also form letters/words with playdoh. Homemade playdoh with scents added in work awesome! (like allspice, cinnamon, etc)
I also took Kimck's advice and only make him do 1 worksheet in math and LA a day. Surprisingly I am filling up his folder with tons of stuff he is doing on his own. Lately he found mayfly nymphs and has been obsessed with them so I had him write 1 sentence a day on them, draw a picture and write spelling words on them. Then I took the words and made word search puzzles, etc with his words. Slowly I am beginning to accept the process.

Oh and on the really bad days, I like to remind myself what the PS told me, "Gifted kids don't really need much anyways. They are fine on their own." ((Humor alert-sarcastic smiley inserted here))
