I'm not sure how old your DS is, but let me clue you in on what's in store for your gifted child.
My DD17 is also considered to be "gifted". She has taken all of the accelerated, honors and AP courses that she can handle. Her summers are not her own anymore. She has chapters to outline, novels to read, analyze and write papers about, math packets to complete and essays to write.
We've dragged text books with us on every vacation for the past 3 years. Spring break is just another excuse to pile on additional projects. We have a 4-day weekend right now and she had to email a physics assignment in today plus she has projects in AP US history, AP English and Career Development all due the first week of June.
SATs are on June 2 and she just finished taking 3 AP exams last week.
Compared to high school, college will be a breeze.
Now, knowing that your DS is probably facing the same future when he reaches high school, would you elect to deprive him of "summer vacation" this year? My advise would be to let him be a kid. Childhood is not a race, it's an adventure.
