Just be honest; it's what we try and teach our kids, right?
I always let the teacher know the list of books DS is reading (many at the same time, going back and forth without losing the gist of any); that we reprogrammed dad's old Robosapien using instructions we found online, etc. Why not? It's what we DID.
I also mention that he doesn't hate but isn't hip on repetitive math exercises, ie: flashcards (now, if we're talking word problems, which he LOVES, he makes up his own, and I mntion that, too).
I mention that he eats greedily, plays loudly, sings offkey, never shuts up, has trouble sitting still in mmusic class, had to have a patch for amblyopia, has horrible handwriting (which we are working on), is clumsy when running ---and for the very first time (now that we had him tested this summer) told them he finished the Percy Jackson series in one month. And finished all 7 Harry Potters as of June. Plus all the HT train your Dragon books, and Lemony Snickets. He just turned 8.
It's not bragging, it's truthtelling, and imho, can only help your child. I also sent a short, sweet supplementary email asking the teacher for appropriate titles/series they think are suitable for him to start next. We're out of DK encyclopedias at the house, and some of the boks he wants to read are what I call TMI titles, for an 8 yr old.
We have to special-order English books (as we live overseas) and I want to place a bulk order for Christmas, so again, it's not bragging--for us, it is essential knowledge; they have that knowledge, I need it, and there is nothing wrong with asking for it. Albeit, politely.
