At Gould, our students work with faculty and use mathematics to find patterns and solve problems. Of course, true to our commitment to experiential learning, these truths are found in traditional classroom settings as well as on playing fields and mountains, in labs, and in the Marlon Family IDEAS Center where our student tutors host weekly Mathematics Help Center sessions.

Departmental Requirements

Three years to include completion of courses equivalent to Algebra 1, Geometry, and Algebra 2. The TI-84 Plus calculator is required for ALL math students at Gould Academy.

Mathematics Course Classes Include:

Algebra 1

This first year course covers such topics as algebraic expressions, linear equations, systems of equations, quadratics, and the introduction of functions. Emphasis is placed on learning algebraic skills and developing a deeper conceptual understanding of the material through problem solving and applications. Use of the TI-84 graphing calculator is introduced.


This course is an exploration of geometric concepts covering parallel theory, similarity, congruence, and properties and attributes of angles, triangles, polygons, and circles. Proof writing and algebraic skills are learned and practiced throughout the year. Real world applications and online manipulatives help students to explore and gain a deeper understanding of the geometric world. (Prerequisite: Algebra 1)

Algebra 2

Functions are explored and serve as a common domain throughout this course. Working with linear, quadratic, polynomial, exponential, and logarithmic functions, new skills are learned and applied to a variety of real world situations. TI-84 calculators are used extensively to illustrate the functions graphically and to provide a visual representation for problem solving. Students are challenged to apply their skills and demonstrate their understanding both orally and in writing. (Prerequisite: Geometry)

Honors Algebra 2

This is a rigorous Algebra II course designed for students who have strong algebraic skills, the capacity to work both independently and collaboratively, and the ability and desire to work towards Honors Precalculus and AP calculus. New algebraic skills are attained through the exploration of functions including, linear, quadratic, polynomial, exponential, logarithmic, and trigonometric. Students enrolled in this course are required to maintain at least a B average. (Prerequisite: Geometry and a strong Algebra 1 background)


This course will extend the study of functions from Algebra II for those students preparing for a regular calculus course. Exponential, logarithmic, rational, and trigonometric functions will be explored. Also included with the trigonometry will be the unit circle and laws applied to triangle measurement. Applications and modeling are integrated into this skills-based course and there is extensive use of the TI-84 graphing calculator. (Prerequisite: Algebra 2)

Honors Precalculus

This rigorous course is designed for students who are planning to take a college-level Calculus course. Strong computational skills are required, as well as an ability to think and work abstractly to solve problems. A variety of concepts and tools from both this and previous courses will be used to solve multi-step problems. Inverse, trigonometric and rational functions are some of the topics that will be explored. (Prerequisite: Honors Algebra 2 and/or departmental approval)


This course extends the concepts of precalculus and introduces the techniques of calculus, including limits, continuity, differentiation, and integration. Students use geometric, algebraic and trigonometric concepts to investigate real world applications. The course prepares students for a rigorous college calculus course and course content is reflected in topics studied in AP Physics. (Prerequisite: Precalculus)

AP Calculus

This is a college-level, high intensity class that serves a twofold purpose: to prepare the students to take the Calculus AB Advanced Placement Exam in the Spring and to provide the calculus tools to students concurrently registered in AP Physics. The class will be taught at a relatively quick pace and the material will be covered in depth. Proofs of basic results from Calculus will be covered throughout the year. A graphing calculator will be used in the class to help students visualize and better understand the functions commonly used in Calculus. Students are expected to take the AP exam. (Prerequisite: Honors Precalculus with an 85 average or better.)

AP Statistics

This is a college-level course that covers the four major areas typically included in a statistics course. Students will be introduced to the four broad conceptual themes: exploring data, sampling and experimentation, anticipating patterns, and statistical inference. Students are expected to take the AP exam. (Prerequisite: Algebra 2 or above and departmental approval.)

Honors Senior Mathematics

Students in Honors Senior Math will get a taste of the concepts from higher level mathematics, including logic, set theory, and number theory during the fall trimester. The emphasis will be on understanding the abstract concepts and learning to write clear and efficient proofs. During the winter and spring terms, the class will switch gears in order to prepare the students for the Calculus BC Advanced Placement Exam. Topics that will be covered include parametric and polar graphing, sequences and series, and advanced integration techniques. The graphing calculator will be used to assist students in preparing for the AP exam. (Prerequisite: AP Calculus)

Mathematics of Financial Matters

Students will explore practical mathematical concepts relating to financial planning, money management, growing and protecting personal wealth, and will evaluate the risks and benefits associated with loans and investment instruments. The fundamental mathematical concepts students will apply include quantitative analysis, problem solving and linear algebra. Students will use spreadsheets to solve real-world problems involving the analysis and synthesis of data and formulas related to compound interest, cash-flow statements, budgets, credit cards and loans, financial aid, and will participate in a stock market game. The fall trimester will focus on financial planning and money management. The winter trimester will focus on income and asset protection. The spring trimester will focus on investing and personal wealth. This course is designed as a three-trimester sequence that can be taken for one, two, or all three terms. (Prerequisite: Algebra 2)
