BTW I have also hear of Integrated H.S. Math I, II && III that take all these subjects and mixed them up. A bit of algebra & geometry all three years. This makes more sense to me but I haven't seen the details of it's implementation. It is hard to change the traditional Algebra, Geometry, Algebra II model. But there is a lot of math that would be helpful to kids that don't fit strictly into "Algebra", such as probability that can be better.

In my state the only math REQUIRED to gradate from H.S. is two years of math class and mastery of Algebra I. For the kids that struggle in math, they often now take a 2 year Algebra I sequence and never get Geometry. And even most universities only require math at the Algebra II level for general entrance.
