AP Calculus AB Syllabus Camden High School Course Description AP courses in calculus consist of a full high school academic year of work and are comparable to calculus courses in colleges and universities. It is expected that students who take an AP course in calculus will seek college credit, college placement, or both, from institutions of higher learning. The AP Program includes specifications for two calculus courses and the exam for each course. The two courses and the two corresponding exams are designated as Calculus AB and Calculus BC. Calculus AB can be offered as an AP course by any school that can organize a curriculum for students with mathematical ability. Calculus AB is designed to be taught over a full high school academic year. It is possible to spend some time on elementary functions and still teach the Calculus AB curriculum within a year. However, if students are to be adequately prepared for the Calculus AB Exam, most of the year must be devoted to the topics in differential and integral calculus. These topics are the focus of the AP Exam questions. Both the AB and BC concepts will be covered, and students demonstrating proficiency of all material will take the Calculus BC exam and will receive a BC score and an AB subscore. Calculus AB represents college-level mathematics for which most colleges grant advanced placement and/or credit. Most colleges and universities offer a sequence of several courses in calculus, and entering students are placed within this sequence according to the extent of their preparation, as measured by the results of an AP Exam or other criteria. Appropriate credit and placement are granted by each institution in accordance with local policies. The content of Calculus BC is designed to qualify the student for placement and credit in a course that is one course beyond that granted for Calculus AB. Many colleges provide statements regarding their AP policies in their catalogs and on their websites. Success in AP Calculus is closely tied to the preparation students have had in courses leading up to their AP courses. Students should have demonstrated mastery of material from courses that are the equivalent of four full years of high school mathematics before attempting calculus. These courses should include the study of algebra, geometry, coordinate geometry, and trigonometry, with the fourth year of study including advanced topics in algebra, trigonometry, analytic geometry, and elementary functions. With a solid foundation in courses taken before AP, students will be prepared to handle the rigor of a course at this level. Students who take an AP Calculus course should do so with the intention of placing out of a comparable college calculus course. This may be done through the AP Exam, a college placement exam, or any other method employed by the college. Student Goals Each student who actively participates and fulfills the expectations of the course will be able to: Work with functions in a variety of ways and understand the connections among these representations. Understand the meaning of the derivative in terms of a rate of change and local linear approximation and should be able to use derivatives to solve a variety of problems. Understand the meaning of the definite integral both as a limit of Riemann sums and as the net accumulation of change and should be able to use integrals to solve a variety of problems. Understand the relationship between the derivative and the definite integral as expressed in both parts of the Fundamental Theorem of Calculus.

(student purchases in the spring semester) Other Course Materials Organized notebook (sections to include: notes, homework, activities, reference) Pencils (standard and colored, or markers if desired) Graphing Calculator: TI-Nspire CAS handheld strongly recommended The Role of Technology The graphing calculator is an integral tool in this course. The TI-83, TI-89, and T-Nspire CAS calculators are used daily to discover and explore relationships within and between concepts. Students are strongly encouraged to purchase the TI-Nspire CAS. Concepts will be presented using Nspire software, and lessons will be taught using the Nspire CAS handhelds if enough students have them. Throughout the course, graphing calculators will be used regularly in guided activities and spontaneously during class discussions in a variety of ways to: Conduct explorations. Graph functions in arbitrary windows. Solve equations numerically. Analyze and interpret results. Justify and explain results of and relationships between graphs and equations.

In small groups, students complete an activity in which each group is given a set of five functions with different types of discontinuities. Using their graphing calculators, students investigate the graphs of the functions to classify the type of discontinuity of each. Students then compute the limits at each discontinuity for each function. A culminating class discussion is held in which students discuss the connections between the limit and type of discontinuity, and how both are revealed in the graph and table for each function.] 4) Rates of Change and Tangent Lines a) Average Rate of Change b) Tangent to a Curve c) Slope of a Curve d) Normal to a Curve e) Instantaneous Rate of Change Unit 2: The Derivative (20 - 25 days, 3 AP Quizzes, 1 Test) 1) The Derivative of a Function a) Definition of a Derivative b) Derivative at a Point [Students complete an exploration of 𝑓(𝑥) = 𝑥 3 − 4𝑥 2 − 9𝑥 + 46 in which they find the derivative at x=2 and x=4 using the definition, and then graph the tangent lines at both points.

They are then asked to tell the x-intercepts (without graphing) of NINT(x2, x, 0, x) and NINT(x2, x, 5, x) and explain. Finally, students 𝑥 𝑑 connect these steps to how changing a in the graphs of 𝑦 = 𝑑𝑥 (∫𝑎 𝑓(𝑡)𝑑𝑡) 𝑎𝑛𝑑 𝑦 = 𝑥 ∫𝑎 𝑓(𝑡)𝑑𝑡.

At least once a week, a miniature (multiple-choice only) AP-exam is administered (in a calculator/no calculator format) and scored to count as a quiz grade. The day prior to these quizzes is spent in class discussion of items from packets completed during the week. Test-taking strategies and embedded concept review are naturally occurring parts of these discussions. 2) Free-Response Practice Students work in small groups to answer packets of free-response questions. (Packets generally include the six questions from a given year; but when it is clear that a particular type of question needs more attention, topical packets are also used.) Once adequate time to answer all parts of all questions has been allowed, students are given scoring rubrics to score their responses. In this collaborative environment, students measure each other and themselves against acceptable justifications and explanations. Students exchange papers within the group to compare approaches and to evaluate the clarity and elegance of responses. 3) Whole-Test Practice A full practice test is administered over four class meetings. On the fifth day, students are placed in small groups to review their scored exams, after which a class discussion is held about the test. Once this cycle has been completed, students attend and organized practice test at a local university. Contact Information Phone: (803) 425-8930, Extension 3642 Email: lisa.twitty@kcsdschools.net Late Work Policy Homework is assigned daily and is communicated on a weekly assignment sheet and on the eChalk class page. The expectation is for homework to be turned in on the first class day after the lesson was covered in class, but assignments may be turned in late for full credit – with two stipulations: a maximum of two assignments per day will be accepted, and all work for the chapter must be turned in before the test for the relevant chapter is administered. Extra Help Policy Mrs. Twitty will be available for after-school help on Wednesdays from 3:15 – 4:15. Additional assistance may be arranged by appointment. August 2009 Lisa Twitty AP Calculus AB Syllabus Camden High School Re-do Policy The day after a test has been graded, the class will be split into two groups: those that mastered the tested content (as demonstrated by earning a minimum of 77) and those that did not. Students who mastered the content will earn bonus points and will serve as peer tutors for those that did not. The following day students who did not master the content will be retested for a maximum grade of 77. Any student who scores lower than the first attempt will earn as a replacement grade the average of the two attempts.
