K.B.
I know my mom did not let us do homework in our room till we were in 5th or 6th grade. We would sit at the kitchen table and do it while she was making dinner or cleaning the kitchen. I know one of my brothers was not the best at keeping on task so, finally half way through 8th grade he hated that he was the only one at the kitchen table doing homework (my youngest brother who is 3 years yonger them this one at the table had already moved on to doing it in his room) so my mom said that he has to prove he can do it without being distracted. Well he has ADHD so he really needed the gentle reminder to keep on tasks still so he was always at the kitchen table even during high school. I believe towards the end of his high school years he finally mastered the task so he was able to do his homework in his room.
To be honest have him do it at the kitchen table, have a school box full of pencils, erasers, sharpener, calculator, compass, ruler, and any other item you notice him needing a lot to do his homework. It is not a punishment to have him doing his homework at the kitchen table it is more of he needs that extra attention and help to keep on task.
If there is a lot of homework maybe after 30 mins of really working at it he can have a 5 min break before buckling down again. If he has 3-4 subjects let him know that after he finishes with each subject he can take a 5 min break to use the bathroom, get a snack or drink, or have him do a few jumping jacks to burn that pent up energy.
You can also make it habit that he always shows you ALL of his homework. Does he write down in a book or calander what needs to be done which days, take a look at it and have him show everything that is due the following day. I understant that he is senstive but this is his education so do what you think needs to be done to keep him on track.
