Mathematics Department - Common Core Algebra 2 Curriculum 2022-23




Course Philosophy/Description 


Common Core Algebra 2 is the capstone course of the three units of credit required for a Regents diploma. This course is a continuation and extension of the two courses that preceded it. Algebra 2 continues the students’ study of advanced algebraic concepts including functions, polynomials, rational expressions, systems of functions and inequalities. While developing the algebraic techniques that will be required of those students that continue their study of mathematics, this course is also intended to continue developing alternative solution strategies and algorithms.  

 

Within this course, the number system will be extended to include imaginary and complex numbers. The families of functions to be studied will include polynomials, absolute value, radical, trigonometric, exponential, and logarithmic functions. Students will be expected to describe and translate among graphic, algebraic, numeric, tabular, and verbal representations of relations and use those representations to solve problems. Emphasis will be placed on practical applications and modeling. Students extend their knowledge and understanding by solving open ended real-world problems and thinking critically through the use of high level tasks. 


Students will be expected to demonstrate their knowledge in: utilizing essential algebraic concepts to perform calculations on polynomial expression; performing operations with complex numbers and graphing complex numbers; solving and graphing linear equations/inequalities and systems of linear equations/inequalities; solving, graphing, and interpreting the solutions of quadratic functions; solving, graphing, and analyzing solutions of polynomial functions, including complex solutions; manipulating rational expressions, solving rational equations, and graphing rational functions; solving logarithmic and exponential equations; and solving equations.
