# Mathematics and Computer Science

The mathematics curriculum instills habits of mathematical thinking that will prepare students for further inquiry in math and computer science, and for using quantitative reasoning. The department helps students recognize the relationships represented by the language of mathematics and learn essential problem-solving skills such as conjecturing, sense-making, and analyzing strategies and solutions.

Through appropriately challenging experiences, students have the opportunity to puzzle over relationships and to develop the habit of questioning. Discovery is recognized as a valuable tool in the learning of math; this discovery takes place in teacher-led classes, individual explorations, and in learning groups that offer a natural context for practicing mathematical communication. At all levels, technology is used to relieve the constraints of tedious computation and to help students conjecture about the mathematics they are studying. Graphing calculators and personal computers enable students to solve problems utilizing rapidly evolving modern methods. Students are taught to approach mathematics from multiple perspectives, including numerical, graphical, and symbolic.

Taking direction from the NCTM Standards and the College Entrance Examination Board, the Math Department strives to engage all students with the challenge, excitement, and relevance of math.

**Computer Science**

The department offers several computer science/computer programming course offerings for students in grades 10-12. These courses include Computer Programming, AP Computer Science, and Advanced Topics in Computer Science. See below for further information on each of these courses.

**BB&N Math Team**

BB&N is one of the few Boston-area independent schools with a competitive math team. The BB&N team participates in the Greater Boston Math League, the Harvard-MIT Math Tournament, and the WPI Invitational. In addition to these off-campus team events, all BB&N students are able to participate in the monthly New England Math League and the annual AMC10/12 competitions.

In addition, BB&N hosts an annual Integration Bee for its advanced Calculus students. The event provides an opportunity for math to become a bit of a spectator sport for a few hours and is enjoyed by the participants and audience members alike.

## Advanced Algebra 1

## Algebra 2 and Honors Algebra 2

The topics studied in this course include linear equations, quadratic functions, transformations, polynomial functions, exponential and logarithmic functions, inequalities, and statistics. Additional topics in the honors course may include symmetry, linear programming, rational functions, and triangle trigonometry. In some cases technology (including graphing calculators and online graphing apps) is used as an efficient approach to a solution, while other times it is used to explore and enhance the students’ understanding of algebraic concepts and relationships.

Prerequisite: Algebra 1

## Geometry

This course approaches Euclidean Geometry with an in-depth analysis of plane, solid, and coordinate geometry as they relate to both abstract and concrete mathematical concepts as well as to real-world problem situations. Topics include deductive and inductive proof, parallel lines and polygons, perimeter and area analysis, volume and surface area analysis, similarity and congruence, right-triangle trigonometry, and analytic geometry. To develop critical thinking and reasoning skills, students are exposed to different technological tools and manipulatives as they discover geometric relationships. Additional topics include statistics and computer programming.

Prerequisite: Algebra 2

## Honors Geometry

This fast-paced course encourages students to think in new ways. Students learn to build on what they know to be true and to avoid making false assumptions. Deductive reasoning and discovery are the common threads that run through each unit in this course. Students make frequent use of technology and participate in frequent group assessments that allow students to complete more challenging material. In addition to exploring the topics taught in Geometry, the Honors Geometry course also studies circular trigonometry, trigonometric identities/equations, the Laws of Sines and Cosines, probability, and combinatorics. Students code in Java during the computer programming unit.

Prerequisite: Algebra 2 and permission of the Math Department

## Principles of Precalculus (Grades 11-12)

Students in this course study polynomial functions, sequences and series, trigonometric functions, exponential, and logarithmic functions. Other topics studied include transformations and rational functions. This course is generally designed for students who are ready for a precalculus course but not yet ready for the increased rigor of Precalculus. Successful completion of this course could prepare Grade 12 students for an advanced college precalculus course or a humanities level college calculus course, and Grade 11 students for Statistics.

Prerequisites: Algebra 2 and Geometry (generally with grades of C+ or higher), or permission of the Math Department

## Precalculus

Students in this course study transformations and modeling, polynomial and rational functions, real and complex roots of polynomials, sequences and series, exponential and logarithmic functions, and circular trigonometry. The study of trigonometry includes the six trigonometric functions (their definitions, graphs, applications, and inverses), a variety of trigonometric identities, the polar form of complex numbers, and the Laws of Sines and Cosines. Other topics may include statistics, combinatorics and probability, and vectors.

Prerequisites: Algebra 2 and Geometry (generally with grades of B or higher), or permission of the Math Department

## Honors Precalculus AB and Honors Precalculus BC

The honors courses take a toolkit approach to a large variety of functions that can be transformed to model phenomena. Honors Precalculus AB studies precalculus topics for the entire year, while Honors Precalculus BC accelerates to include an introduction to limits and differential calculus. Since Honors Precalculus BC begins the AP Calculus syllabus after Spring Break, students in Honors Precalculus BC who move on to Calculus the following year are expected to take the Advanced Placement Calculus BC course. A deviation from this sequence is rare and requires permission of the Math Department.

Prerequisites: Algebra 2, Honors Geometry, and permission of the Math Department
