1 Wheeler High School To: Honors Calculus and AP Calculus AB Students From: Mrs. Barry, Mrs. Massey, Mrs. Walls, and Mr. Furstein - Calculus Instructors Re: Summer work Honors Calculus and AP Calculus AB are college level courses covering material traditionally taught in the first semester of college calculus. These courses are taught in one semester consisting of daily 90-minute classes. Students need a strong foundation to be ready for the rigorous work required throughout the term. Completing the review packet, which consists of topics studied in pre-requisite courses, will help ensure a proper background. Students should epect to work approimately 0 hours on this assignment. The packet will be given a grade based on completeness and accuracy of solutions. Students are epected to show all work with logical steps. You must show your work for problems on separate paper. Do not list only an answer. The packets are due to your instructor on your first day of class. Students enrolled in Honors Calculus and AP Calculus AB will be using a graphing calculator throughout the course. A TI 89 calculator will be available to AP Calculus students for use during the semester if they do not already have one. AP Calculus AB students will have the opportunity to continue studying Calculus for a second term through the BC Calculus course. The BC course will cover material traditionally taught in the second semester of college Calculus. The AB course is a prerequisite for BC Calculus. Students taking both the AB and BC courses and passing the AP Calculus BC test could earn up to 6 hours of college credit depending upon the Advanced Placement policy at the college. Some colleges also award credit for a passing score on the AP Calculus AB eam. Since the AP test is only offered in May, students taking only the AB course during the fall semester should be prepared to study for the test independently. The success of each student in the Honors Calculus or AP Calculus program depends upon diligent effort, consistent completion of homework assignments, and practice of newly learned skills. Although a suggested assignment is given for each lesson, completion of some assignments may be optional. Calculus is a challenging, stimulating, and dynamic field of mathematics and we look forward to sharing our enthusiasm for the topics with you. If you have any questions or need to contact someone over the summer, please feel free to me at Lynn.Barry@cobbk.org. Sincerely, Mrs. Lynn Barry Math Department Chair
