Ds 8 is fairly bright,has always been above age related for everything,taught himself to read before school,photographic memory,learnt all his tables in a couple of weeks,very able at the piano learns music pieces v quickly etc.He's not g&t just all round bright at most things.
I'm kind of worried as he makes silly mistakes with easier stuff eg he'll leave the odd capital off a sir name but put in perfect use of commas,speech marks,spelling etc. In maths he'll fly though something but make one or two really silly mistakes in the odd calculation which he can do instantly when pulled up on.
I feel he's kind of arrogant in his approach iykwim ie he doesn't double check,take his time etc.Sometimes if he's working something out that doesn't come instantly he'll chuck the pencil across the room in temper(at home).He's used to doing his maths homework in a few minutes.He hates anything he's not good at eg art and PE and won't work at them to better himself(like most of us have to in various things).I'm not bothered re the art and PE it's just an observation re his attitude.
I'm concerned that this is maybe(maybe it isn't) due to not being stretched enough at school and he's just not used to having to puzzle things out.I'm also concerned that he'll get/is getting lazy.
Any ideas on how to handle it?
