# Course Title: Algebra 2

Course Title:Algebra 2

Levels:2, 3, 4, 5

Grade:11

**Length of Course:**One Year

Credits:5.0

Prerequisites:Algebra

Description:

The purpose of the Algebra 2 course is to build a strong foundation in preparation for students to ultimately take Calculus. Beginning with a review of Algebra 1 topics to enhance critical skills and concepts, students will move onto more advanced topics. A real-world orientation is emphasized in guiding the approaches to exercises and problems, and technology is integrated, wherever appropriate, in the form of graphing calculators and computer programs.

Building ona more intuitive foundation developed in Algebra 1, the course formalizes the idea of what makes a function and emphasizes various families of functions. In addition to becoming proficient with linear, quadratic, and exponential functions, students will begin to develop an understanding of logarithmic and polynomial functions as well. These topics will be utilized both for their abstract ideas and for modeling real-world phenomena.

Evaluation:

Student performance will be measured using a variety of assessments, including projects, teacher-generated tests and quizzes, and a common departmental Midterm and Final Exam. Assessments will emphasize how well key concepts have been understood as well as the depth to which required skills have been mastered.
