DS6 has similar issues with writing. It is the one area that he isn't able to achieve instant success in. This actually turned out to be a blessing in our siutation - heterogeneous classroom in public school. He has had to struggle a bit to organize his thoughts on paper, but he's seeing the struggle payoff - good for work ethic. I say go ahead and "instruct" him as long as you set realistic goals. Then show him how much his effort is paying off by saving old writing. I see writing as a great chance to praise DS for effort rather than performance.
