4 years of math is required but Algebra I counts even though more than half the kids take Algebra I by 8th grade.
I think that he does like to learn with the other kids even though that involves him tuning out for a good portion of class. On the other hand, he does like to speed through things as well so that is the upside of the online course.
It is hard to say whether he loves it enough for it to have a career component. The reason for the first two accelerations beyond the built-in GT acceleration was to avoid killing the spark/passion.
I like the sideways idea but I think a lot of the cool applications require a higher level of math knowledge than Algebra I. Computer programming may be a possibility to occupy his time if he finishes the course too fast.
Just out of curiosity, what would have been the normal sequence for your DD? The sequences that I am used to seeing are:
Year 1: Algebra I
Year 2: Algebra II
Year 3: Geometry/Trigonometry
Year 4 (1st half): Pre-calculus
Year 4 (2nd half): Calculus AB
Year 5: Calculus BC
Year 1: Algebra I
Year 2: Algebra II
Year 3: Geometry
Year 4: Trigonometry and Pre-calculus
Year 5: Calculus AB + BC
