Hi! I probably won't be able to help, but I just wanted to share that we are having pretty much the same problem with DS6. I think that having a well-behaved, adaptative child might sometimes be a curse in disguise.
Our son doesn't even say at school that he already knows many of the contents he is being taught, so every time I try to get him more challenging work I seem to come across as some sort of "tiger mom".
We have scheduled a meeting with his teacher this month because the school has now complained about some behavioural issues. I'll keep you posted if I get any useful insights!
