Precalculus/Calculus

In this course, students complete a unique 12-part year-long project ranging from algebra through calculus. This original project begins with students choosing three locations on the Earth and involves using linear equations, creating piece-wise functions to match data, using limits to test for continuity, finding and using first and second derivatives, using integrals to solve problems, and other topics such as average value, arc length, trapezoidal approximations, and even partial derivatives.

Readings: 
"A Short History of Nearly Everything"
"Functions in the Real World"
Media Used: 
TI-83 Graphing Calculator
Google Earth
Significant Assignments: 

Create your own homework assignments: Throughout the year, students create their own homework problems to complete and then exchange those problems with other students in the class. Students keep their problems in a safe place so that the final product is like a student-created math textbook they can bring to college.

Create your own exams: Students consistently create exams to assess their knowledge about the particular subject we are studying. Students exchange exams and work together to find and correct mistakes. On exam day, students each have their own unique exam.

Significant Activities or Projects: 

The Map Project is a year-long 12-part project ranging from algebra through calculus. This is the main performance-based assessment students complete.

The Native Country Project, wherein students collect data from some aspect of their native countries (population, car accidents, disease, etc) and use the data to explore applications in math.

The Products Project, in which students try to save companies money by repackaging their products to use less surface area (keeping the volume constant) or hold more volume (keeping the surface area constant)

Writing to Learn Math

Students review fundamental concepts from Algebra, Geometry, and Statistics and demonstrate their understanding via repeated short writing exercises which strengthen students' abilities to describe math operations and processes using words and statements. Students then complete indepth investigations on three topics: 1) Is the Coney Island Coin Toss Game Fair?; 2) How do manufacturers decide to package grocery store items?; and 3) How does the student government of BCS determine the ticket price for a dance?

Readings: 
Essays using math from trade magazines
Former students' Math papers
Significant Assignments: 

Students write out every step involved in factoring a polynomial to extreme detail and compare with other students.

Students compare written analyses of a similar problem to see how different styles of writing help a writer to convey his/her point.

Significant Activities or Projects: 

What do we know about carnival games? They may seem so easy to win, but in reality, we don’t win every time. Students investigate the original design of the Coney Island Coin Toss Game and decide if its design gives players a fair chance to win.

Walk into any supermarket and look at the shapes lining the shelves. Manufacturers consider dozens of factors before determining which shape will best suit the consumer and boost the company's profits. Students explore package design and uncover some of the reasons for the shapes that manufacturers have chosen. Students use their knowledge of geometry and algebra to investigate different ways to decide whether or not it is better for manufacturers to sell items in “bulk” or to sell individually packaged items and determine if manufacturers are packaging their items as efficiently as possible.

Suppose you are a student council member who is responsible for planning a BCS student dinner dance. Plans include hiring a DJ and buying and serving dinner. You want to keep the ticket price as low as possible to encourage student attendance. Identify and use systems of equations to analyze costs and make decisions. Then write a report detailing your choice of band, the cost of a catering service, and your ticket price recommendation. Present this report to Student Government.

Sample PBATs: 
Are carnival games fair?
How can I plan a student event to maximize profit or minimize cost?

Data Analysis

Knowledge of statistics is a valuable asset that will help students make sense of the vast amount of information we are presented with everyday. The goal of this course is to give the student a hands-on ability to apply the fundamentals of statistics to make informed decisions. This will be accomplished by examining the skills required to read data, interpret data and judge others' claims about data. In addition to manual calculations, we will look at the usefulness of technological tools such as the graphing calculator and Microsoft6 Excel in data analysis.

Significant Assignments: 

Analyze the difference between various kinds of studies; apply knowledge of statistics to critique data presented and conclusions reached.

Determine factors which may affect the outcome of a survey; consider outcomes of various hypothetical situations on outcomes.

Significant Activities or Projects:
