Mathematics

Note: This year, students will be registering for courses with their Advisor. We encourage students and families to make use of the Curriculum Guide to investigate their choices, check prerequisites, and confirm entry requirements. Current teachers, Department Chairs, and Grade Deans should also be consulted as resources. As we are distance teaching and learning through RCDS@home, when you read the below policies, please disregard references to signatures, sign-ups, conversations, and approvals. Once course selections are made, each Department will review them in order to approve or recommend another approach.

Overview

The mathematics curriculum is characterized by depth, breadth, and flexibility. These qualities enable students to pursue the study of mathematics as far as they are able while also enjoying the process.

Algebra 1, Geometry, and Algebra 2 & Trigonometry are required of all students. These courses encourage students to be creative, precise, and rigorous when dealing with abstract concepts. For students who have acquired the necessary concepts and skills, various elective courses are offered. Most students follow the traditional analysis sequence through Precalculus and Calculus.

DEPARTMENTAL POLICIES REGARDING ENTRY INTO HONORS/AP COURSES

A graphing calculator (a Texas Instruments TI-84 Plus or TI-83 Plus) is required in the second semester of the geometry course and the subsequent courses to enhance the study of the algebraic, geometric, and numeric representations of problems.

Admissions into an Honors Math class is dependent upon all three of the following:
1. Recommendation from the teacher of the previous course.
2. Year-end grade of A+ from a regular section;
  Year-end grade of B from an Honors Geometry section;
  Year-end grade of B+ from an Honors Algebra 2 & Trigonometry section;
  An equivalent year-end grade from the Middle School
3. Signature of the department chair, who may require a placement test
For entry to AP Calculus AB courses, a student must have
1. Recommendation of the current Advanced Precalculus teacher and the math department
2. Minimum grade of 85 on the March exam in Advanced Precalculus
3. Minimum average of 85 for the second semester in Advanced Precalculus
A student in Honors Precalculus needs a B or better to continue into AP Calculus BC.
Any accelerated student in Honors Precalculus needs an A- or better to continue directly to AP Calculus BC.
For entry to AP Statistics, a student must have
1. Approval of the math department
2. Minimum year grade of:
  B in Advanced Precalculus or A in Advanced Algebra 2 & Trigonometry.

A student who takes Advanced Algebra 2 & Trigonometry in the 11th grade and who wishes to take non-AP Calculus in the senior year may do so if the student meets the following criteria:
1. Minimum grade of B in Advanced Algebra 2 & Trigonometry
2. Prior approval as obtained in a meeting with the math department chair
3. Completion of a pre-approved summer precalculus course
For maintenance of placement in an honors or AP course during the school year, the policy is as follows: If any honors or AP student receives a grade below B- at the end of the first quarter or first semester, the course teacher, in consultation with the department head, will review the placement. The decision to transfer a student from an AP or honors course will be made jointly by the Principal, the department head, the section teacher, the advisor, and the student.
Entrance into 9th grade Geometry from the Middle School requires a minimum year grade equivalent to C+.

The Mathematics Department does not consider it appropriate for students to bypass any of the courses in the Upper School sequence; however, qualified students who wish to accelerate may take our Geometry and Algebra 2 courses concurrently. This requires approval of the department.
