Mathematics & Computer Science

The Overlake Mathematics and Computer Science Department delivers a rigorous curriculum which provides students with the foundations necessary for college as well as 21st century careers. Critical thinking and problem-solving skills are emphasized throughout our modern, streamlined curriculum. Overlake Math and Computer Science teachers ensure that our students develop an understanding of both the computational skills and theory in all concepts that are presented; we care about not just the “how” in mathematics, but also the “why.”

Mathematics Program

In the Middle School, students work together in a differentiated math classroom as a single community in 5th and 6th grade. In 7th and 8th grade, students are placed into either a 2-year Algebra sequence or a 2-year Algebra/Geometry sequence. All Overlake Middle School students leave 8th grade with a rigorous course in Algebra, and all Upper School students have the opportunity to explore math electives, such as Calculus, Statistics, Linear Algebra, or Discrete Math, by their senior year.

In the Upper School, students will complete (or will have already completed prior to admission) a traditional progression of Geometry and Algebra 2.  After this point, students will have the choice between several paths of electives (see Mathematics and Computer Science Department Program Map). 

Most of the Upper School Math courses have two tracks: Traditional or Honors/AP. Students are placed in the Traditional or Honors/AP course based upon teacher recommendations as well as student interest. Both tracks cover the foundational material required for success in college mathematics and 21st century careers. Honors and AP (Advanced Placement) courses are intended for students who show special interest and aptitude in math. To earn a placement in an Honors/AP course, students must demonstrate the ability to master concepts quickly, be independent learners, and perform at the top level in prerequisite courses. Honors/AP courses are significantly more challenging than the Traditional courses and demand more from students in terms of homework, independent study skills, and intellectual focus. Placement in the Honors/AP track one year does not guarantee the same placement the following year, and students may transition between the two tracks at any point in the program.  Both mathematics tracks are considered highly rigorous by colleges and universities, and students should consider their own interests, course load, and extra-curricular demands when evaluating the pros and cons of each track.

Computer Science Program

There are opportunities for students with any level of experience in computer science and programming to explore and enrich their understanding of these subjects at The Overlake School. “Computer Science Foundations” and “Computer Science Principles” are introductory courses for middle-school and high-school students, respectively. No prior computer science knowledge is expected; in fact, we work to prioritize access for students with no background in programming.  AP Computer Science A is offered in the high school, and while no previous programming experience is required, students with any level of background are welcome to take the course. For Upper School students, we also offer a wide array of electives in computer science topics, from mobile app development to data visualization.

For more information on course sequencing, please see the Mathematics and Computer Science Department Program Map.

Graduation Requirements

To graduate from The Overlake School, students must earn a minimum of three credits in core Math courses (Geometry, Algebra 2, Precalculus, Calculus, AP Calculus AB, AP Calculus BC, AP Statistics, Linear Algebra, Discrete Math) in the Upper School. Almost all recent Overlake graduates have completed four or more credits in Math. Students who have completed high-school-level mathematics courses in Middle School (either at Overlake or another school) cannot use those courses towards graduation and must still earn three Math credits in the Upper School. Computer Science courses are not core math courses and may not be used to satisfy the mathematics graduation requirements.

The Overlake School offers a Summer Accelerated Geometry course for current or incoming Upper School students who have completed their first course of Algebra. At this time, this is the only accelerated course we allow for students in our program. This accelerated course does not count towards the graduation requirement and is only intended to allow students to reach advanced electives such as Calculus by their senior year however, students will receive a grade for the course, and it will appear on the student’s high school transcript.

The Mathematics Department believes in the quality of our courses and teachers. Students are not allowed to accelerate or test out of courses once they are placed in an upper school math course. Per school policy, no non-Overlake course credit will be accepted for graduation or acceleration purposes without prior approval from the department chair and Upper School Head. This happens only on exceedingly rare occasions, when a student has extenuating circumstances that prevent them from following our prescribed curriculum.

Students wishing to engage in extra math outside their classwork or over their breaks are encouraged to engage with enrichment programs, either locally or otherwise. Our teachers are happy to provide them with such resources and program listings.

Math 5

Mathematics & Computer Science

All fifth grade students take Math 5. Computation with whole numbers, decimals, and fractions is honed. Keen attention is paid to understanding the effect of operations on quantities in order to develop estimation skills and improve number sense. Students examine algorithms and number composition to enhance understanding of arithmetic properties. Geometry, number theory, ratio, percent, measurement, and pre-algebra concepts are explored through hands-on activities, problem solving, and practice workbooks. Fifth graders also have math labs during which they explore open-ended problems, participate in Math Olympiad contests, and extend their study of topics. Students are regularly prompted to reflect on, prove, or justify solutions during focused discussions. Whole class instruction and smaller skill-group lessons meet varied student abilities. Students continually revisit learned concepts through classroom routines and mathematical games.

Math 6

Mathematics & Computer Science

As students solidify a foundation in decimals, fractions, percent, ratio and proportion, they will become more comfortable with how variables can be incorporated within these concepts. Topics include operations with rational numbers, simplifying algebraic expressions, solving equations and basic geometry. Problem solving techniques and algebraic processes are emphasized throughout the year as students learn to communicate their solutions. Reading, listening, writing, and speaking skills are stressed as students learn to express mathematical ideas just as they would in other subject areas. There is a focus on developing a breadth and depth of mathematical knowledge and skills, with a strong emphasis on conceptual understanding. An equal emphasis is placed on conceptual understanding and skill development – the "why" as well as the "how".

Algebra 7

Mathematics & Computer Science
One-year Algebra 1 course, to be taken in 7th grade.

There are two options for completing Algebra 1: a two-year course and a one-year course.  Placement into these courses is done by the middle school math faculty in conjunction with the department head.

This is a rigorous, complete Algebra 1 course. The course content includes solving of linear and quadratic equations, graphing linear equations and inequalities, exponents, radicals, polynomials, systems of equations, and some rational expressions. Because it includes all of the abstract concepts through the solving of quadratics, placement into this course is not solely based on strength in arithmetic, but is also based on evaluation of abstract thinking, academic maturity, and a student's intellectual drive. Applications to science, in addition to other real-world situations, are integrated throughout the course.

Algebra IA

Mathematics & Computer Science

Calculus

Mathematics & Computer Science

Pre-calculus

This capstone course in high school mathematics introduces students to the concepts of differential and integral calculus. This course provides a rigorous alternative introduction to Calculus without the stress or focus on preparing for an AP exam.  Fall semester includes derivatives, related rates, curve-sketching and optimization. Spring semester introduces definite and indefinite integrals, area and volume. Through practice with applied problems, students learn to communicate their methods using appropriate language, symbols and units. A solid understanding of geometry, functions, and trigonometry is necessary for success in this course.  Students who complete this course can still elect to take AP Calculus AB the following year.  

AP Calculus (BC)

Mathematics & Computer Science

Calculus and current teacher’s recommendation

First-year concepts of differentiation and integration are extended to polar, parametric, and vector functions. Students master new methods for evaluating limits, evaluating integrals, and solving differential equations. Series and tests for their convergence as well as power series and polynomial approximations are studied. The workload, pace, and content of this course is comparable to a second or third semester course at colleges and universities.

AP Statistics

Information Literacy & Technology
Mathematics & Computer Science
Full-year elective. This course is intended as a second math elective and cannot be taken in lieu of a course in the normal sequence until the senior year. Even seniors are strongly encouraged to take their regular math course concurrently.

Algebra II

The purpose of the AP course in statistics is to introduce students to the major concepts and tools for collecting, analyzing and drawing conclusions from data. Students are exposed to four broad conceptual themes:

  1. Exploring Data: Describing patterns and departures from patterns
  2. Sampling and Experimentation: Planning and conducting a study
  3. Anticipating Patterns: Exploring random phenomena using probability and simulation
  4. Statistical Inference: Estimating population parameters and testing hypotheses

Successful AP statistics students have good quantitative reasoning, good reading comprehension, clear written communication and consistent study habits. Students will be challenged to think critically about data, to use statistical methods with a deep level of understanding, and to write persuasive responses to real-world questions. A graphing calculator will be the student’s constant companion.

Linear Algebra

Mathematics & Computer Science
Semester elective

Precalculus or Precalculus Honors

Linear algebra is a branch of mathematics studying linear equations and their relationships to matrices and vector spaces.  This topic is a fundamental component of many important mathematical applications including finance, cryptography, artificial intelligence, web search, computer graphics and more.  The course will cover the basic elements of a college-level Introduction to Linear Algebra course, including: matrix algebra; determinants; elementary vector spaces; linear transformations; and characteristic equations and eigenvalues. As time and resources permit, students will use computing technologies to create and explore applications of linear algebra. 

Discrete Mathematics

Mathematics & Computer Science
Semester elective

Precalculus or Precalculus Honors

Discrete Mathematics is the study of mathematical structures that are discrete, separated or distinct; in contrast with Calculus which deals with continuous change. It is an important area of pure and applied mathematics, as well as providing the mathematical basis for the understanding of computers and modern computation. Discrete Mathematics is also important in the sciences, where it has increasing application in many areas, an exemplar of which is the understanding of DNA sequences in molecular biology. This course will cover topics based on instructor and student interest such as Boolean logic; enumerative combinatorics; recurrence relations; relation theory and lattices; voting theory; theoretical computer science and computability theory; and graph theory.

Programming language: Java. Students with a working knowledge of object-oriented programming fundamentals in java will be given the opportunity to further practice and extend those skills in this applied course. This course focuses on student engagement in the learning process through a practical, collaborative approach that allows for a creative and authentic experience. The majority of activities will be centered around learning and practicing the details of developing mobile apps using core OOP principles and various APIs available. Concepts related to the process rather than coding, such as best practices of mobile development and strategies of completing large projects in teams, will be presented and implemented as well. The final goal of the course will be to complete, in a group, a thoroughly polished Android app incorporating all skills learned during the semester.
