Mathematics

Reason and communicate
mathematically

At Walker’s, mathematics instruction is guided by a desire to instill critical thinking and the integration of technology into classroom instruction.

Our math faculty provide experiences that encourage and enable students to value mathematics, develop confidence in their mathematical ability, use mathematics to solve problems, and be able to reason and communicate mathematically.

Instruction is problem-based and focuses on the practice of new skills and concrete applications. Mathematical rigor is introduced at all levels, commensurate with the course level. Our lower-level courses are taught with a great deal of structure, providing a solid foundation for abstract thinking, integration, and synthesis needed in the more advanced selections. We offer regular and honors sections for every grade level; 98% of our students take a four-year mathematics program. 

The traditional subjects of algebra, geometry, and trigonometry provide the theoretical background for students intending to further their education. For students who plan to pursue careers in mathematics, science, and engineering, the pre-calculus and calculus courses are preparation for higher-level mathematics courses.

Various teaching techniques are employed to address multiple learning styles in order to help each student find and develop her unique abilities and strengths in math. At the core of our mission is the determination to encourage our young women to find their own “unique voice” in our mathematics classrooms as students are encouraged to lead discussions, ask clarifying questions, and contribute alternative methods of problem-solving.
