Course Description

In this course students use their geometry and algebra skills to begin their studies of trigonometry and advanced functions.  Students will be required to express understanding using qualitative, quantitative, algebraic, and graphing skills.  Graphing, and interpreting graphs, is a major component to this class; having a personal graphing calculator is highly recommended.

Teaching Methods

This class is taught mainly through mathematical inquiry, lecture, and practice.  Students are given general overviews of each section, which are followed by in-class practice.  Students will often work in cooperative learning groups and communicate their results, usually through white boarding, to their peers.  Students will be using software to inquire and expand different aspects of mathematical phenomena.  Daily assignments are a major part of the mathematical learning process.  Students are expected to complete every assignment and give full participation in class for successful completion of this course.

Assessment

Students will be assessed with the following:

  • Daily Homework
  • Quizzes
  • Projects
  • Chapter and Semester Exams
