Welcome to the CHS Math Department!
Department Chair: Jessica Dunford
Algebra I (9th grade) 2 semesters
Algebra I includes the introduction of variables, constants, expressions, equations, and functions. The language of numbers is examined. Topics include solving equations, simplifying expressions, understanding order of operations, performing operations with positive and negative numbers, exploring polynomials, factoring, graphing (linear and quadratic equations), working with radicals, and expanding arithmetic knowledge.
Geometry (1 semester)
This course is for students who have successfully completed the standards for Algebra I. The course includes the deductive axiomatic method of proof to justify theorems and to tell whether conclusions are valid. Methods of justification will include paragraph proofs, flow charts, two-column proofs, and verbal arguments. There is an emphasis on two-and three dimensional reasoning skills, coordinate and transformational geometry, and the use of geometric models to solve problems. A variety of applications and some general problem-solving techniques are used to implement these standards, including algebraic skills.
Algebra II (1 semester)
This course is for students who have successfully completed the standards for Algebra I. Functions, polynomials, rational expressions, complex numbers, matrices, and sequences and series. Emphasis is placed on practical applications and modeling. Graphing utilities will be used to enhance the understanding of realistic applications through mathematical modeling and aid in the investigation and study of functions and their inverses. They will also provide an effective tool for solving and verifying equations and inequalities.
This course is for students who have successfully completed the standards for Geometry and Algebra II. The content of this course will serve as appropriate preparation for a calculus course. Math analysis is intended to extend students' knowledge of function characteristics and to introduce them to another mode of mathematical reasoning.
This course is intended to provide students with experiences in using the computer and graphing calculator to solve problems which can be set up as mathematical models. Students who successfully complete the standards for this course may earn high school mathematics credit. Programming, ranging from simple programs involving only a few lines to complex programs involving subprograms, will permeate the entire course. Fundamental concepts and principles in the field of computer science will be covered. Students will develop and refine skills in logic, organization, and precise expression that will enhance learning in other disciplines.
Math 163/164 Precalculus Dual Enrollment (3 credit hours per semester)
Math 163/164 is for students who have successfully completed math analysis. Math 163 presents college algebra, matrices, and algebraic, exponential, and logarithmic functions. Math 164 presents trigonometry, analytic geometry, and sequences and series. These courses are available through dual enrollment through Mountain Empire Community College or Southwest Virginia Community College. The classes are taught on-site at Clintwood High School via the internet or fiber optic classroom setting.
