1 Stone Bridge Math Department June 06 Dear Advanced Placement Calculus BC Student, Congratulations on your wisdom in taking the BC course. I know you will find it rewarding and a great way to spend your year. As always, I do not want you to stagnate or ferment those marvelous brain cells over the summer. Therefore, it would be beneficial for you to periodically refresh your memory on some math basics before beginning class in September. With this in mind, your first assignment is attached. This assignment is due no later than Friday, September, 06 with no eceptions. This is a 0-point grade. Your work/process is worth points so you must show all work to earn full credit. To encourage you to complete this during the summer, there will be a free quiz grade of 0 points given for turning this in on the first block day of your class, August 9, or August 0. This due date is fied, so if you will not be in school this day it is your responsibility to mail the assignment in to school with a postmark date matching the due date. Do the work independently first and then you may work together on the tweaking of your responses if you choose. Include any questions or comments you have on the material or the specific problems given. We will use this as a diagnostic instrument to determine where we need to begin our review of the AB content. The curriculum, pace, and rigor of the AP Calculus BC course is determined by College Board guidelines. It is suggested that all students enrolled in this course take the AP eam. This year, the eam is on Tuesday May 9, 07 and will require the use of a graphing calculator. Although a large portion of the course is a review/etension of AB topics, there is about 60% new content to cover. This year the eam will follow a similar format as the AB eam but there are some difference we will talk about. Since you are masters of the AB topics, I am sure that the little etras of the BC curriculum will not only be easy but also eciting as well. I am looking forward to a year of more calculus fun! Calculus BC is a demanding course and will require an average of approimately 90 minutes of homework time for every 90-minute block. Getting ahead during the first week of school will be advantageous. The AP Calculus course requires you to think mathematically, something some of you may never have done before. Do not be discouraged in the beginning if it takes you awhile to think mathematically. By the time May 07 rolls around, you will be ready. Throughout the course, I will Verbally NAG you. Verbally NAG is a way to remember the four ways that the College Board epects you to think mathematically. Verbally through written words and thoughts spoken out loud Numerical being able to understand charts, tables, etc and use them to answer questions Algebraic solving equations and word problems using algebra skills Graphical comprehending and interpreting graphs and using them to answer questions Have a restful summer and be ready to talk the Calc again in September. Please follow the links below to register for your SBHSMATH account and download the Summer Assignment. Sincerely, Mr. Marchio

2 This packet is a review of some Pre-Calculus topics and some Calculus topics. It is to be done NEATLY and on a SEPARATE sheet of paper. Use your discretion as to whether you should use a calculator or not. When in doubt, think about if I would use one that should guide you! Points will be awarded only if the correct work is shown, and that work leads to the correct answer.
