Our state has gone to Common Core so there is no more "algebra" class. Here is the content our state (NC) is using for High School Math 1:

Chapter 1: Solving Linear Equations
Chapter 2: Graphing and Writing Linear Equations
Chapter 3: Solving Linear Inequalities
Chapter 4: Solving Systems of Linear Equations
Chapter 5: Linear Functions
Chapter 6: Exponential Equations and Functions
Chapter 7: Polynomial Equations and Factoring
Chapter 8: Graphing Quadratic Functions
Chapter 9: Solving Quadratic Equations
Chapter 10: Square Root Functions and Geometry
Chapter 11: Rational Equations and Functions
Chapter 12: Data Analysis and Displays

As you can see the algebra is a tad lighter than most of us are used to in Algebra 1, more geometry is mixed in, and there's a bit on Data Analysis. Next year, there will be no more "geometry" class as we knew it -- that will also be a Common Core class (HS Math 2) and it will continue the algebra/geometry/and other stuff mix. This will continue through HS Math 3, after which point, the students will be set free to take more traditional higher level math classes and the Common Core requirements will have been fulfilled. That is the way our state is doing it. I am not sure whether all states are splitting the HS Common Core standards into 3 years, but my guess is most are. These classes replace algebra 1, geometry, algebra 2.
