DD is in a gifted magnet and I'm still trying to figure out how things work, but I think basically everyone accelerates at least a year in math. Other kids might accelerate two or more years. Knowing that she'd probably be accelerated at least a year, I've been doing Khan Academy with her at home over the summer. Since she just finished third grade I clicked on 4th grade and went down the list of skills to find what she might not know. There are video lessons for each skill as well as practice problems. Then I went onto fifth grade and did the same thing. Then we got through part of sixth grade. DD said all the kids did a pre-test of some sort and it was harder than even the sixth grade stuff she had been doing (it sounded like algebra with negative numbers), so it sounds like they move kids fast. Who knows what level they will stick her in. Anyway, hope that helps. It is free and easy to sign up for an account so it doesn't hurt to try it.
