Mathematics

Whether math is your passion or not, Chatham Hall’s mathematics program is for you. Our small classes and extra assistance help allay the math anxiety that some girls feel. And our results are exceptional. In a recent survey, nearly 92 percent of our graduates reported receiving a high level of encouragement in math, science, and technology. In addition, the average SAT math score for our alumnae completing our boarding school curriculum was 588, compared to 477 nationally for females and males combined.

NOTE: Students may double up in math by taking Algebra 1 and Geometry or Geometry and Algebra concurrently, with permission.

Algebra I
Discrete - Math

This one-semester elective course will work to expose students to multiple concepts that provide the foundation for various math topics including logic, number theory and methods of proof, sequences, induction, and recursion, set theory, relations, counting principles, probability, and graph theory. The course can be paired with Personal Financial Literacy for 1 math credit.
Geometry
Algebra II
Applied Algebra & Trigonometry

This course builds on the concepts begun in Algebra 2, providing an opportunity to review key skills and learn others as a bridge course to precalculus. Algebraic skills to be reviewed will include factoring polynomials, simplifying algebraic expressions, and the basics of exponential functions. In addition, characteristics of functions will be explored along with their applications. New algebra skills to be learned will include the basics of logarithm functions and their applications, solving 3x3 systems of equations, and the fundamentals of matrices among others. Following the algebra content, the skills involved in right triangle trigonometry, special right triangle trigonometry, and oblique triangle trigonometry will be explored. Students are required to have a TI-84 Plus or TI-84 graphing calculator.

Year-Long Course – 1 Credit

Prerequisite: C- or better in Algebra 2 or successful score on placement test.
Probability and Statistics

Probability & Statistics will expose students to the basic statistical concepts and methods in a manner that emphasizes understanding the principles of data collection and analysis rather than theory. Much of the course will be devoted to discussions of how statistics is commonly used in the real world and will include projects that allow students to work with real-world data. Students will examine graphical and numerical summaries of data to describe the distribution of a variable, or the relationship between two variables. Furthermore, they will produce their own data to learn how to design good surveys and experiments, collect data from samples that are representative of the whole population, and avoid common sources of biases. Lastly, students will study probability and inference using the language of probability and the properties of numerical summaries computed from random samples to draw conclusions about populations of interest.

Year-Long Course – 1 Credit

Prerequisite: Successful completion of Algebra 2 or Algebra 2 placement test.
Precalculus
Honors Precalculus
Calculus
Advanced Calculus
Advanced Statistical Analysis
Advanced Linear Algebra

Linear algebra studies linear spaces and the mappings between them. Almost every area of mathematics uses the tools of linear algebra in some form or fashion. Basic examples include n-dimensional space, rotations, and reflections. Spaces such as the polynomials of degree less than or equal to n and the continuous functions on a closed interval are studied as well. The first half to two-thirds of the course cover traditional topics such as matrices, solving systems of linear equations in n unknowns, rank, dimension, determinants, linear transformations, inner-products spaces, and matrices with complex entries. Other topics that could be covered dependent on student interests and background are canonical forms, application to multivariable calculus and differential equations, and bilinear/quadratic forms.

Prerequisites: Advanced Calculus and a completed application for approval.
Robotics Engineering & Coding
Advanced Computer Science Coding
