I'm thinking there could be quite a range of things that could potentially cause this, including of course being so far ahead already in academics that he's bored. Whatever it is, it sounds like it's related to school and he's holding things together well at the beginning of the week but falling apart as the week goes on. Other than being due to boredom/gifted child placed below level in classroom - here are a few ideas:
* possibly dealing with asynchronicity in development or an undiagnosed learning challenge
* personality mismatch with teacher or bullying from classmates
* buildup of sensory challenges over several days gets to the spill-over point where he can't cope with it - I have a dd who was diagnosed with SPD when she was his age, and she could bottle up quite a bit for a day or so in the classroom, but over several continuous days in class it started to take a toll on her.
* is there something in the classroom environment that he's sensitive or allergic to?
* could it be as simple as he's getting a good night's sleep on weekend nights, goes to school well rested on Monday morning, then doesn't get the same type of quality sleep during the week so it catches up with him by the middle-end of the week?
So - what I think is, I wouldn't have any idea without knowing a lot more about the boy and his environment. I hope his parents are able to gain a good understanding of what's up and find a good fit for him re school.
