Algebra II

Algebra II Curriculum

Course Description

This class continues to develop the fundamental algebraic skills such as: operations, algebraic expressions, and solving equations. Students will develop the ability to create and apply models to situations represented by linear, quadratic, exponential, logarithmic, polynomial, rational, and radical functions. Students engage with relevant mathematical contexts to make math meaningful. 

In Units 1 through 3, students will solidify their understanding of expressions, equations, inequalities, and functions. This gives a foundation of simplifying, solving, and graphing in known functions that can later be applied to new situations.

In Units 4 through 10, students will learn to simplify and evaluate expressions, solve equations and check solutions, and model and describe these new functions.  They will apply these models to new situations.

As students encounter challenging problems, and practice asking for help and a willingness to learn from others, they build the social emotional learning competencies of self-management, self awareness, relationship skills, and social awareness.

*  Honors Algebra 2 follows the same course sequence as Algebra 2 with differences in depth and rigor. Additional topics are embedded in various units to support curriculum standards in future honors and AP courses. These topics include (but are not limited to) difference quotient, Pascal’s Triangle, probability, etc.

Course Essential Questions:

  • How can students write expressions in the simplest form?

  • How do students determine the most effective strategy in simplifying expressions and solving equations?

  • How many solutions are possible for different equations and are they real, complex, or extraneous?
