Course Selection Guide for Grade 9
2900 Geometry/Trigonometry 2 (1 credit)
This high school level course is designed for students with outstanding mathematical ability. Geometry is a modern development of Euclidean Geometry covering congruency, similarity, parallelism, perpendicularity, areas, and volumes. Concepts from coordinate geometry are reviewed with an emphasis on the integration of algebra and geometry. Trigonometry topics include indirect measurement, the Laws of Sines and Cosines, and theories/applications relating to tangents, apothems, and inscribed polygons.
Prerequisite: Algebra 2/Trigonometry 1, B- or better.
2910 Algebra 2/Trigonometry 1 (1 credit)
This high school level course is designed for those students with good mathematical ability and interest who have mastered the concepts and skills of Algebra 1. Algebra 1 concepts are reviewed and extended. The solutions of linear equations, linear inequalities, linear systems, and quadratic equations are addressed. Operations with rational, irrational, and complex expressions are stressed. Other topics include series and sequences, trigonometry of the tight triangle, powers and roots, and basic variations.
Prerequisite: Algebra 1, C or better.
2915 Algebra 1 (1 credit)
This course is designed for those students with solid mathematical ability who have successfully completed Pre-Algebra. The course extends previously learned arithmetic skills to expressions involving variables. Fundamental operations and properties are studied. Major topics include linear equations and inequalities, exponents, polynomials, factoring, quadratic equations, proportions, functions, data analysis, applications, and problem solving.
Prerequisite: Pre-Algebra, B- or better.
2920 Algebra 1 Topics (1 credit)
This course is designed for those students who have successfully completed Pre-Algebra and who have demonstrated an understanding of arithmetic operations. The course addresses the major concepts of a traditional Algebra 1 course. Pre-Algebra topics are reviewed and extended. Additional topics may include studies in ratios, proportions, and percents.
2970, 2980, 2990 Mathematics 9 (1 credit)
These courses are designed to meet the needs of special education students.
