2015 Bishop Kelley High School Summer Math Program Course: AP Calculus AB & BC NAME: DIRECTIONS: Show all work in the packet. This material will be collected, graded, and points awarded at the discretion of each teacher on the first day of the math class. A test on this material will be administered during the first week of the class. An additional resource for help with this packet is http://www.khanacademy.org. It provides videos of about 10 minutes in length on hundreds of different math topics. Feel free to email me with questions and or concerns ttokarchik@bishopkelley.org Math Teachers will be available in C-1 the following dates/times if you need help. Date Time Monday July 27th 9-10:30am Thursday July 30th 9-10:30am Monday August 3rd 9-10:30am AP CALCULUS Summer Assignment Name_______________________________ “Contrary to common belief, the calculus is not the height of the so-called „higher mathematics.‟ It is, in fact, only the beginning.” -Morris Kline AP Calculus Summer Assignment Due Date: The beginning of class on the first Monday of the school year. The purpose of this assignment is to have you practice the mathematical skills necessary to be successful in AP Calculus. All of the skills covered in this packet are skills from Algebra 2 and Pre-Calculus. If you need to, you may use reference materials to assist you and refresh your memory (old notes, textbooks, online resources, etc.). While the graphing calculators will be used in class, there are no calculators allowed on this packet. You should be able to do everything without a calculator. AP Calculus is a fast paced course that is taught at the college level. There is a lot of material in the curriculum that must be covered before the AP exam in May. Therefore, we cannot spend a lot of class time re-teaching prerequisite skills. This is why you have this packet. Spend some time with it and make sure you are clear on everything covered in the packet so that you will be successful in Calculus. You can also use the packet throughout the year as a review tool for those concepts as they arise. Of course, you are always encouraged to seek help from your teacher if necessary. This assignment will be collected and graded the first Monday of the school year. Be sure to show all appropriate work to support your answers. In addition, there may be a quiz on this material during the first quarter. Good Luck and we look forward to a great year next year!
