I'd be very cautious about this, actually - I think many teachers might feel afronted (unless you're a teacher yourself, in which case you may have an easier time, or not!). I did, with some trepidation, take in some work DS had done at home to an early parent-teacher meeting. I emphasised that DS had asked me to and that he was getting upset and that I thought *he* wanted her to know what he could do. I think that if the problem is that your DS doesn't show his teacher what he can do, then it would be a good idea to take that as the problem, and build up a packet of advanced stuff to show her. It seems more likely - and more positive to assume! - that the teacher is unaware of what your son can do, than that she is unable or unwilling to provide material at the right level for him, so I'd go in with that attitude if I were you. In our case, DS's teacher did indeed react very positively: I hope your DS's will too!
