# Math

*As mathematician and author Oleg Gleizer says, "Math is freedom. If we don't know math, our choices are so limited."*

#### Pre Algebra Honors

Pre-Algebra uses a Saxon curriculum called ‘Course 3’ that is based on concepts and skills learned in 6^{th} Grade (Course 2). Saxon lessons are ‘distributed and integrated’, which means we do a little at a time on all of the concepts listed below. We rotate and build on each of them, reviewing constantly so the students can build a solid foundation across the board. After a set of five lessons is covered, they are reviewed while we study another set of five lessons before the test is given. This allows the material to really sink in, which in the end reinforces actual learning and even makes studying for midterms and finals less stressful.

In this course we will focus on the following concepts:

*Number & Operations*- We will review what we know about real numbers (integers, decimals, and fractions) and the operations we can perform on them (addition, subtraction, multiplication, and division).

*Algebra*- We will explore the concept of substituting a variable for an unknown number and then learn to manipulate the equation to solve for a variable.

*Geometry*- We will learn about the coordinate plane, how to plot ordered pairs, and how variables and equations may represent a continuous set of ordered pairs that we can then graph as a line. We will also explore the properties of triangles, quadrilaterals, and circles.

*Measurement-* We will learn how to convert measures using unit analysis. We will also find perimeters and areas of geometric figures.

*Data Analysis & Probability-* We will take what we know about finding an ‘average’ and expand that into other measures of central tendency such as median, mode, and range. We will also explore simple statistics by learning about different types of probability and ways to organize data.

*Problem Solving-* Throughout the course we will use the concepts we learn to apply to word problems and real world situations. We will practice determining what we know, what we want to know, and finding the simplest way to use one to find the other by using variables.

#### Algebra 1 Honors

Algebra I is an Honors course using Saxon curriculum that is based on concepts and skills learned in Pre-Algebra (Course 3). Saxon lessons are ‘distributed and integrated’, which means we do a little at a time on all of the concepts listed below. We rotate and build on each of them, reviewing constantly so the students can build a solid foundation across the board. After a set of five lessons is covered, they are reviewed while we study another set of five lessons before the test is given. This allows the material to really sink in, which in the end reinforces actual learning and even makes studying for midterms and finals less stressful.

In this course we will focus on the following concepts:

Saxon lessons are ‘distributed and integrated’, which means we do a little at a time on all of the concepts listed below. We rotate and build on each of them, reviewing constantly so the students can build a solid foundation across the board. After a set of five lessons is covered, they are reviewed while we study another set of five lessons before the test is given.

In recent years, the skills acquired by taking Statistics and Data Analysis have become much more desirable to both colleges and employers alike. At GV Christian School, even our elementary students are introduced to the basic concepts of probability as early as first grade.

In this course we will focus on the following concepts:

#### Pre-Calculus

Pre-Calculus is an Honors course using Pearson curriculum that is based on concepts and skills learned in Algebra II. Although we do not cover the entire book, the concepts are chosen so that the students may move directly into a Calculus I Course (AB) or Statistics, whether at GV Christian School or at a college level.

In this course we will focus on the following concepts:

*Fundamental Concepts of Algebra*- We will review some of the more difficult concepts of Algebra II, such as factoring and solving polynomials, expressions with exponents (scientific notation, rational exponents/radicals), rational expressions, and linear inequalities.

*Functions and Graphs*- We will expand on what we know about functions by graphing basic functions and exploring slope of linear functions. We learn to transform and combine functions, and to evaluate both composite and inverse functions.

*Trigonometric Functions*- We will use our introduction to Trigonometry learned in Algebra II to really spend some time on this subject, learning about radian measure, the unit circle, trigonometric functions of special angles and any angle, graphs of trigonometric functions and their inverses. We will also apply these skills to word problems and real-world situations (i.e. Physics).

*Analytic Trigonometry-* We will use the trigonometric functions to learn to verify trigonometric identities. We will also learn several formulas that help manipulate trigonometric equations.

*Conic Sections and Analytic Geometry-* We will introduce the special properties and equations of various conic sections such as the circle, ellipse, hyperbola and parabola. We will explore the rotation of axes and parametric equations, as well as introduce polar coordinates.

#### AP^{®} Calculus

In this course we will study everything in the Calculus AB guideline as it appears in the AP^{®} Calculus Course Description. The ultimate goal is to introduce students to the major concepts of a first-year college calculus course, with the overall objective of preparing the student for the Advanced Placement^{®} exam in May. Throughout the course, instructional practices to enhance understanding, skills, and use of technology are emphasized to incorporate multiple representations.

Before studying calculus, all students should complete four years of secondary mathematics designed for college-bound students; courses in which they study algebra, geometry, trigonometry, analytic geometry, and elementary functions. These functions include those that are linear, polynomial, rational, exponential, logarithmic, trigonometric, inverse trigonometric, and piecewise defined. In particular, before studying calculus, students must be familiar with the properties of functions, the algebra of functions (domain and range, add and even, periodic, symmetry, zeros, intercepts, and so on) and know the values of the trigonometric functions of the numbers 0, π/6, π/4, π/3, π/2, and their multiples.
