Course Outline, Mathematics - Pre-Calculus - Course Description: Pre-Calculus emphasizes mathematical thinking, the use of mathematical models, and the understanding of mathematical functions and graphs. Specified topics include equalities and inequalities, operations with real numbers, radical and absolute value equations, polynomial functions, rational functions, exponential functions, logarithmic functions, trigonometric functions, matrices, vectors, limits, and derivatives. Course Objectives: This course is intended to: Engage students in mathematical reasoning. Develop students abilities to approach pre-calculus topics from graphical, numerical, and algebraic points of view. Help students learn to read mathematics. Help students become independent learners of mathematics. Develop students abilities to create mathematical models and use these models to solve problems. Engage students in the solution of problems, especially open-ended problems that apply precalculus topics. Develop students ability to write about mathematical ideas and problem solutions. Prepare students for calculus. Essential Questions: 1. How do we solve equations algebraically and graphically? 2. How do patterns and functions help us describe data and physical phenomena and solve a variety of problems? 3. How can collecting, organizing and displaying data help us analyze information, make reasonable predictions, and inform decision-making?

Schedule: TBA Extra help hours: Tuesday through Friday at 8 a.m. Monday through Thursday at 3 p.m. Math Center after school in room 518. Materials: 1. Primary textbook: Foley, Gregory, Bert K. Waits, Daniel Kennedy, and Franklin D. Demana. Pre-Calculus graphical, numerical, algebraic. Boston: Addison-Wesley, 2004. 2. Secondary textbook: Dressler, Isidore, Edward P. Keenan, and Ann X. Gantert. Amsco s Mathematics B. New York: Amsco, 2002. 3. Graphing Calculator: TI-83 is recommended. 4. Pencils and eraser 5. Notebook 6. Folder or binder to keep quizzes, exams, and handouts. Class Atributes: 1. Lecture on concepts and techniques. 2. Presentation of examples and strategies. 3. Applications to demonstrate relevance and extend learning. 4. Large and small group discussions and explorations. 5. Reading and writing assignments. 6. Learning, review, and practice through homework assignments. 7. Active student engagement in group work and discussions. 8. Quizzes, and exams to encourage and monitor learning. Course Requirements and Expectations: 1. Active participation requires attendance and arrival to class in time to be prepared for work when the class period begins. Students are expected to complete class-work activities in the time allotted, and complete homework assignments in the format provided by instructor. 2. Respect your classmates as well as your instructor. Discussions in class will pertain to the topic of the course. All students have a right and responsibility to ask questions and give insight related to the understanding of course content. 3. Participation in large and small group discussions is required and assessed for active engagement and contribution. 4. All work turned in on exams, quizzes, and individual papers must be entirely your own. Behavior contrary to this will result in a grade of F on the assignment. Students should be aware of and adhere to the school s academic integrity policy on plagiarism. 5. If a student misses any assessment, he/she is responsible for rescheduling it with me within five days after the student returns to school. Failure to do so will result in zero for the missed evaluation.
6. Quizzes will be given every week. Quizzes will count for 80% of your grade. Students arriving late on the day of a quiz will not be given extra time to finish it. Quiz revisions will not be allowed but I will drop your lowest quiz score. 7. Academic Dishonesty will not be tolerated. Guidelines for group work: 1. Every group member has the right and responsibility to contribute to the group s work. If you find that you tend to dominate the group discussion, make an extra effort to enable, encourage, and empower other group members to participate. 2. Share your ideas with others. You ll be surprised to find out how often your ideas will help lead to a right answer! No idea or question is stupid. 3. Arrive prepared and ready to start. When discussing homework in a group, be sure to try all problems in advance and identify where you have questions. 4. Take responsibility for your own learning. Share your strategies/questions with the aim of having others understand what you are getting at and where/why you are stuck. This is different from I couldn t get... and expecting another student to show you their answer. 5. Having fun is allowed, but stick to the task!!
