The Lower School Mathematics students learn the four whole-number operations in a step-by-step approach which seeks to develop mastery by the end of grade four. At each level, students read and solve word problems using the number operations that they are learning. Place value, measurement, geometry, fractions, and concepts of numbers are introduced and reinforced. Considerable use of manipulative objects teaches concepts and reinforces understanding. In first grade, addition and subtraction are introduced, and the concept of place value is taught. This work is extended during second grade with the introduction of regrouping in two-digit subtraction and three-digit addition. Multiplication is introduced in second grade. In third grade, multiplication and division are emphasized, including the multiplication and division facts, long division with remainders, and two-digit multiplication. In fourth grade, the emphasis is on complete mastery of all whole number theory which has received attention throughout the curriculum, in grades one through four.

The Middle School Mathematics program’s primary aim is to develop number-sense skills, problem-solving techniques, and the ability to see and to describe numerical and geometric patterns and relationships. Beginning with Computations and Concepts in grade 5, students are helped to start construction of the bridge that connects the concrete world of arithmetic to the abstract world of algebra. Student participation in class activities and discussion is encouraged as is the development of good communication skills. Many students will be ready to take Algebra I in the 8th grade, but others will not yet be ready for the necessary abstraction. The course sequence allows students to develop mathematical maturity at different paces and yet arrive at the common goal of completing the bridge to the abstract with the same level of competence. Students in grades five and six will use the TI-30 series of scientific calculators to explore interesting numerical patterns and to enable them to solve realistic applied problems. Students in grade seven (beyond Mathematical Transitions) will be issued a TI-83 graphing calculator in their mathematics class at the beginning of the school year, and they should bring them to class daily. All eighth grade students returning to St. Mark’s for the 2001-2002 school year are required to bring their school issued TI-83 graphing calculator to each class period. New eighth grade students will be issued a TI-83 calculator in their mathematics class at the beginning of the school year, and they should bring them to class daily. In the Spring, the department will make recommendations regarding each boy’s course selection for the following year. The Mathematics Department makes recommendations based upon what would be the best course for the students. Thus, the students are expected to enroll in that course. Enrollment in an honors section is approved by the Department Chair.

The Upper School Mathematics courses seek to develop skills and concepts which will enable students to analyze and solve problems from a wide range of mathematical areas, including algebra, geometry, probability, and the standard elementary (polynomial, rational, trigonometric, logarithmic, and exponential) functions. Emphasis is placed on active student participation in all aspects of the learning process. Other goals include the development of logical and critical thinking, of competence in the use of language and symbols, and of the ability to communicate clearly. Appropriate technology will be used to explore mathematical concepts and to allow a rich array of applied problems.

Students must complete the required sequence of mathematics courses through Algebra II before graduation, and must take mathematics courses through their junior year, but they are encouraged to continue their study of mathematics through the senior year. The department offers a variety of electives to meet the needs and interests of students who complete the Algebra II course before the end of the junior year. Each spring the department will make recommendations as to appropriate course selections for students wishing to take an elective and/or an honors level course. The Mathematics Department makes recommendations based upon what would be the best course for the students. Thus, the students are expected to enroll in that course. Enrollment in an honors section is approved by the Department Chair.

All students returning to St. Mark’s for` the 2001-2002 school year are required to bring their school issued TI-83 graphing calculator to each class period. New Upper School students will be issued a calculator in their mathematics class at the beginning of the school year, and they should bring them to class daily.

Geometry students will use a class set of TI-92 for instructional purposes.
