6th grade mathematics

Sixth grade math focuses on applying and expanding upon mathematical concepts learned in elementary school mathematics. Students will begin by reviewing and developing their understanding of rational numbers. Students use this understanding to write, interpret, and solve expressions and equations. They also will review, apply, and expand their understanding of fractions, decimals, and percentages to write ratios and rates and use these skills to solve real-life situations (i.e., tax, interests, discounts, etc.) Students will reinforce their understanding of the measures of central tendency (mean, median, and mode) and range and learn how to use, analyze, and predict future outcomes through various types of graphs. Students will also work with two and three-dimensional shapes to calculate perimeter, area, and volume. Finally, students are taught different strategies that can be used to solve word problems or problems that pose unfamiliar situations.

 

7th grade mathematics

7th grade Pre-Algebra is an introductory course to the basics of Algebra. Students begin by reviewing foundational concepts learned in 6th grade mathematics including writing and solving expressions and equations, fractions, decimals, percentages, ratios, and proportions. After reviewing these foundational concepts, students begin studying the basics of writing and graphing linear equations and inequalities. Students focus on how to write an equation in two variables and the real-life situations that can be modeled using linear equations and inequalities. Next, students learn how to multiply monomials (single term expressions) and binomials (two term expressions) to create various polynomials (multiple term expressions). Finally, students look at basic geometrical concepts such as angle postulates and theorems, properties of similar triangles, the Pythagorean Theorem, and properties of two-dimensional figures. This class uses Bob Jones Pre-Algebra text as its main resource.

 

8th grade mathematics

8th grade Algebra 1 is the equivalent of first year Algebra offered in high school. In this course, students begin by reviewing how to write and solve expressions and equations in one variable. Students then move on to study and discuss linear equations and inequalities in depth through learning how to write and graph linear equations and to analyze real-life situations by using linear models. Next, students begin their studies in quadratic functions by again learning to write and graph quadratic functions and studying real-life situations that can be model using quadratic functions. Students end the year by exploring the use of radicals in equations and also how to simplify rational expressions (where the numerator and denominator of the expression both include polynomials). This class uses Bob Jones Algebra 1 text as its main resource.
