Course name: AP Calculus AB Revised: Aug 11, 2008 Course Description: In AP Calculus AB, students will explore four main ideas from calculus: limits, derivatives, indefinite integrals, and definite integrals. Problems will be approached through a balance of multiple representations including: graphically, numerically, analytically/algebraically, and verbally. Wherever practical, concepts will be applied to analyze real-world situations. Graphing calculators and/or computers will be used on a regular basis to help solve problems, experiment, interpret results, and support conclusions. Students will learn to communicate mathematics through the use of a math journal and having time each day to work in groups to exchange ideas and approaches and to reflect on homework assignments. A variety of assessments will be used to including paper based tests and quizzes, homework, group and individual laboratory work. In order to prepare students for the AP exam, tests and quizzes will contain questions similar to those that appear on the AP exam in terms of content, difficulty, and structure. Primary text(s) and other major resources: Calculus of a single variable Larson, Hostetler, and Edwards (D.C. Heath and Company, 1994) Page1of6

Notes This is a sample of a sheet that we typically use to analyze various calculus problems using a multiple approaches. We use it to compliment our work with the graphing calculators. The "notes" section is used for a written and analytical approach. The "table" section below is used for numerical approach with enough room to examine the function, first derivative, and second derivative. The "graphs" section is for a graphical approach allowing the student to see function and derivative behavior either on the coordinate plane and/or using intervals along a number line.

Teacher Notes: This Box Project is an example of one of our project that requires the student to apply calculus to solve a real world problem. In this case, the student has to design a cereal box that meets the volume requirements while minimizing the amount of material used in order to help minimize the environmental impact. The students must use an analytical, graphical, numerical, and written approach to describe their solution. Furthermore, to complete the realworld hands-on experience, the students must actually construct their proposed box. The next project (Zoo Project) is also a real-world application of calculus. Students use limited materials to construct a zoo that maximizes living spaces for the animals. Again, the students use multiple approaches (analytical, written, numerical, and graphical) to help gain a deeper understanding of the solution. Consistent with the hands-on experience, students complete the project with a blueprint scaled map of their proposed zoo configuration. Students will explore these, and several other application of calculus throughout the year.
