Mathematics and Computer Science

Welcome to the Secondary Division Math Department at Saint John's School, where we are committed to providing students with a comprehensive and rigorous mathematical education. 
 
In 7th grade, students begin their mathematical journey with Prealgebra, laying the groundwork for success in AGA and beyond. Our program follows the Algebra 1, Geometry, and Algebra 2 sequence, ensuring that students build a strong foundation in algebraic concepts, geometric reasoning, and advanced algebraic techniques. Through interactive lessons and collaborative activities, students develop essential mathematical skills and problem-solving strategies.
 
As students progress through the AGA sequence, they have the opportunity to enroll in honors-level courses in both Geometry and Algebra 2. These courses provide an enriched curriculum that challenges students to deepen their understanding and master advanced concepts.
 
Our program offers three levels of Precalculus, allowing students to tailor their studies to their abilities and interests. For those interested in pursuing advanced study, we offer a range of options, including Advanced Placement (AP) Calculus courses, AP Statistics, and courses in Financial Topics.
 
For students seeking advanced study, we offer Post-AP Math Topics, where they can explore topics such as multivariable calculus, linear algebra, and discrete mathematics. Through independent exploration and guided inquiry, students deepen their understanding of advanced mathematical concepts and develop critical thinking skills.
 
At Saint John's School, we believe in providing a well-rounded mathematical education that prepares students for success in college and beyond. Our dedicated team of educators fosters a supportive and inclusive learning environment, where students are encouraged to ask questions, explore new ideas, and develop their critical thinking skills. Through a combination of rigorous coursework, hands-on activities, and personalized instruction, we empower students to become confident problem solvers and lifelong learners.
