Grade 9 - Mathematics

Algebra I: A Function Approach Part 1 (Credit: 0.50)

This course is designed to provide varied approaches to solving real-world application problems. The curriculum focuses on identifying functional relationships including determining dependence, identifying and analyzing rate of change, making predictions from data, and using data to generalize and develop equations to predict trends. The primary focus is on developing linear functions and solving linear equations, linear inequalities, and linear systems. Developing quadratic functions and solving quadratic equations are covered to a lesser extent, and exponential functions are introduced.

Algebra I: A Function Approach Part 2 (Credit: 0.50)

Algebra I: A Function Approach Part 2 is a continuation of Algebra I: A Functions Approach Part 1. Part 2 provides students with more approaches to the real-world application of algebra. The continued focus of this course is on functional relationships and the various uses of a rate of change. This course moves on to writing and solving equations, linear models in two variables, linear inequalities, systems of equations, and inequalities. Polynomials, their applications, and the factoring of polynomials are examined. Quadratics, their roots, factors, zeros, and solutions are introduced, followed by the quadratic formula, laws of exponents, exponential functions, and functions of inverse variation.

Algebra I: Part 1 (Credit: 0.50)

Algebra I: Part 1 topic areas include algebraic expressions and equations, writing numbers in exponential form, using standard and scientific calculators, integers, absolute values, review of additive identity, like terms, using reciprocals to solve problems, evaluating expressions using order of operations, inverse operations, eliminating fractions, identification of the x-and y-axes, linear equations, graphing with constants, rules of exponents, binomials, trinomials, using the FOIL method, factoring out monomials, trinomial squares, and quadratic equations.

Algebra I: Part 2 (Credit: 0.50)

Algebra I: Part 2 continues coursework from the Algebra I: Part 1 title that covers finding solutions of linear systems of equations by graphing, eliminating variables, motion problems, using negative one as a factor, identifying the least common multiple of expressions, ratio and proportion, using inequalities to solve problems, equations with absolute values, irrational numbers, radical expressions, finding the value of a function, using vertex and axis of symmetry or the T-table, problem solving involving joint and combined variation, and identifying and evaluating the discriminant of a quadratic equation.

Geometry (Credit: 1.00)

The Geometry title introduces basic geometric terms and covers geometric concepts including angles, perpendicular and parallel lines, rays and transversals, measuring line segments, lines, segments, sides and vertices of angles, acute, obtuse, and right angles, parallel and skew lines, acute, obtuse, and right triangles, calculating perimeter, volume and area of trapezoids, polygons, proportional ratios, pyramids, cones, spheres, chords, circumference, tangents, and angle measurement.

Pre-Algebra (Credit: 1.00)

GC Pre-Algebra is a transitional mathematics course for grade levels 8-9. The purpose of this course is to shift the learner from the concrete world of arithmetic into the abstract world of algebra. The first step in this process involves performing operations with integers. The student is then introduced to variables and learns how to use them in simplifying expressions, adding like terms, and solving equations and inequalities. Next, the basic rules of exponents are explored, and the coordinate plane is introduced. The concepts of fractions, ratios, proportions, and percentages are reviewed. Finally, the student is introduced to probability, statistics, and geometry.
