Course 2 (Advanced Algebra, Geometry, Statistics): Course 2 is the second year of the Core-Plus Mathematics Project’s (CPMP) four year integrated math program. It combines Advanced Algebra, with Geometry, Trigonometry, and Statistics. Main topics include: Matrix operations, solving matrix equations, and solving systems of equations in Standard Form, Slope-Intercept Form, and Matrix Form. Transformations are presented on the coordinate plane and focus on reflections, rotations, translations, and size changes of both lines and polygons. Perimeter, area, and volume is revisited in the context of the coordinate plane and symbolic rules are used to represent various transformations in coordinate and matrix form. A multi-representational approach is used to study Families of Functions and their characteristics, specifically symmetry, intercepts, increasing vs. decreasing, and asymptotic behavior. The properties of exponents are investigated along with radical expressions in the larger context of Radical and Fractional Power Models. The three basic trigonometric functions of Sine, Cosine, and Tangent are introduced as well as right triangle trigonometry. Topics in Statistics and Probability include association, correlation coefficients, lines of best fit, and making predictions from patterns of association. Students visualize and build understanding about situations involving chance by using simulation and mathematical analysis to construct probability distributions.
