Honestly, in our experience, schools are much more interested in addressing children's perceived social weaknesses and emotional issues in early elementary than they are in helping children improve upon their academic strengths. The level of support our children received for social/emotional issues was MUCH higher than the level of support that was offered for their academic strengths, even though in one case the lack of addressing academic needs was actually causing the other issues.
They may be much more likely to help your son resolve/avoid a possible "weakness" than to help him build upon an academic strength. If the teacher is suggesting wording to use in the email you should seriously consider doing it, even if it is different than the wording you would use. She probably knows what would work.
