I cannot answer your specific questions, but I have had 2 recent meetings about my 10-year old son. He skipped 2nd grade, and now in 6th. He definitely needs even more acceleration in Math. The principal acknowledged to me that this would be the first time his school has done something like this, but he is open to it adjusting the math class he is placed in next year.

He did, however, express a reluctant stance to make any changes now, with a few weeks remaining in the current school year. My question to him was, can he remain in the 6th grade math, but instead of being given more worksheets reviewing the same material, can he be given 7th grade worksheets or a workbook that shows examples and then the problems. The principal didn't think it was a good idea to give a child math problems to do on his own, without any instruction.

I don't know if he doesn't think it's fair to the child, or that he simply doesn't think the child can possibly learn this way.

The district has very little experience with gifted students, but at least the principal is open to conversations and most possibilities.

My personal opinion is, not to let too much time go by while they research what was done in the past. It should not dictate what they do for your child today. Each gifted child has different needs and cannot follow a set "gifted" curriculum. Needs to be a more custom approach to challenge the child and keep him learning.
