Thanks for your support. I have also tried to take a break, two weeks at a time. Then come back to it, he'll have a few good days, and he reverts to his school strike again.
I know he is still young and really my main focus this year is getting math, reading, and writing done. I have even tried to lighten his load thinking that I might be pushing him too hard, but on his good days he can breeze through his work without a problem. So by cutting back I feel like I'm giving in to what he wants, which is not do school. I am hoping he does snap out of this phase by next year. I'm glad to know others have made it through this phase.
