Our district use accelerated Math curriculum. (Glencoe/ McGraw Hill/Holt, etc..) Apparently the textbook companies have different curriculum for different pace.
Our schools start TAG Math in 2nd grade and finish middle of 3rd. 3rd grade finish near the end of 4th and 4th grade finish at the end of 5th. 5th graders start at 6th grade level and finish around mid 7th.7th will finish at 8th grade level.
So they will start algebra at 7th grade.
NOW, that's good for majority of TAG kids. DYS kids will need more than that. Although our ISD has defied TAG curriculum, some may need more radical acceleration. My DD is strong in Math and she may take 8th grade Math test at the end of this year and hopefully start algebra next year.
I think it is easier to choose a class in middle and high school. You can just pick what suits you but in elementary school, you are stuck with the curriculum for the whole year. And most teachers resistant to differentiate in the classroom.
