I was on the AP track, and we did-
8th grade: Algebra
9th grade: Geometry
10th grade: Trigonometry
11th grade: Alg II
12th grade: Calculus
I don't remember what we learned math-wise in 5th grade, but googling up 5th grade math worksheets shows decimals, percentages, adding/subtracting fractions, and multiplication of numbers of 4 or more digits.
