Mathematics Department

  • Radnor’s mathematics curriculum has been developed to accommodate the various levels of a student’s mathematical abilities and skills. Although traditional math skills will be taught in all courses, the goal of the mathematics curriculum will be to develop thinking skills through emphasis on mathematical concepts. Use of problems requiring critical thinking will be employed to better prepare the student for a world which is becoming more technologically dependent. Students should follow teacher recommendations when deciding which sequence of courses to select.

    Seminar level courses are intended for the highly motivated math students and are designed to challenge the most mathematically capable students. The courses will involve rigorous pacing and workload with teacher expectations intended to challenge the student. The course will require more independent and self guided learning (with an emphasis on writing explanations) than all other courses.

    Honors level courses are intended for the motivated math student who is very good with mathematics but needs more teacher guidance to assist in the mastery of the material. The course will involve accelerated pacing and a demanding workload with some written explanations expected. Students on this level will be prepared to take AP Calculus AB.

    Advanced level courses will feature a more challenging pacing and workload with teacher guidance to assist in the mastery of the material. Students enrolled on this level should be seeking to satisfy college requirements/expectations of mathematics course but not necessarily have an interest in pursuing math related college majors. Any student who wishes to advance in math and to be eligible to take Calculus in High School can do so by taking Algebra II and Geometry concurrently, or by taking an approved Geometry summer school course at the expense of the parent(s)/guardians. The student must also take the RHS Geometry.

    College Prep level courses will feature a moderate pace and workload and a higher degree of teacher-guidance to assist in the mastery of the material. These courses will cover material necessary to prepare students for the Keystone Exams as well as prepare the student to take the SAT test if post secondary education is desired.

    Students interested in pursuing college majors in the science, engineering, medical, and mathematics fields should enroll in the Honors level courses.

  • Radnor High School Mathematics Department Courses Flowchart


    The mathematics curriculum is intended to meet the needs of all students. To aid each student in determining his/her appropriate course of study in mathematics, the classroom teacher evaluates the progress of each individual at course selection time and recommends a specific course for the following year. This personal evaluation takes into account attitude, mathematical background, future plans, and current achievement. As a result, a student may be recommended to move from one level to another. Students should pay careful attention to these recommendations, as well as to the prerequisites, before electing a course.

    The mathematics department believes that the very nature of the mathematics curriculum must be changed to meet the needs of our students as they prepare for their future. Mathematics problems and the methods used to solve them have changed with technological advances. The understanding and competent use of technological tools are important to all our students. The department requires that each student have his/her own calculator. A scientific calculator, such as the TI-34 is sufficient for courses up to and including Geometry. For all courses at the Algebra 2 Level and beyond, a graphing calculator such as the TI-84 PLUS is required. More sophisticated graphing calculators are optional for honors courses. Classroom instruction includes demonstrations on the TI-84 PLUS calculator. Since graphing calculators are allowed on the SATs, we encourage all students to be proficient in their use. The department realizes that graphing calculators are expensive. If financial considerations are a problem, please notify the teacher or the department chairperson.

Pre-Algebra Courses

  • Introduction to Algebra I (05040412)


    1.0 Credit; Unweighted

    Length: Year; Format: Meets Daily
    Grade(s): 9
    Prerequisite(s): 8th grade Intensive Math or Teacher Recommendation


    This course is designed to be the first year of a two-year study of Algebra I and will provide students with a foundation in the algebraic strand of mathematics, which includes understanding patterns, relations, and functions, representing and analyzing mathematical situations and structures using algebraic symbols, using mathematical models to represent and understand quantitative relationships, and analyzing change in various contexts. Mathematics itself is looked at not just as calculation but also as a modeling language, as a process for logical thought, and as a field of study. This approach to Algebra I is organized around families of functions, with special emphasis on linear functions. Students will learn about each family of functions, how to represent them in multiple ways: as verbal descriptions, equations, tables, and graphs. They also will learn to model real-world situations using functions in order to solve problems arising from those situations. Course pacing and structure will allow for important skills to be honed through additional practice time. Students at this level complete Algebra I in two years and will take the Algebra I Keystone Exam upon completion of the second course.

    Traditionally, calculus has been the mathematics course taken by college freshmen. There is currently a growing realization that students also need to be prepared in the areas of linear algebra, probability and statistics, logic, and other discrete mathematics topics. This need arises because of the ever-increasing role of computing in all disciplines and the importance of discrete mathematics in computing. The objective of this course is to provide an introduction to traditional first semester calculus and to introduce students to the many topics in discrete mathematics – both of which have important applications in engineering, management, and the social sciences.
