# Math Essentials

## Course Description

Semester A

Students begin the first semester of this course with a review of how to use basic arithmetic operations with whole numbers, integers, fractions, mixed numbers, and decimals. More complex concepts are built on these basics. Students revisit simplifying order of operation problems. They will also learn how to apply the properties of addition and multiplication, as well as the distributive property, to equation solving. This semester ends with a review of solving inequalities in one- and two-steps.

Semester B

In the second semester of this course, students learn about ratios, rates, and proportions, and find where they can use these concepts in their own lives. Students will also work with percentages. They will perform calculations and apply percentages to real world scenarios. This semester includes a study of the coordinate plane and linear equations. Students revisit plotting ordered pairs, graphing and writing equations, as well as using these ideas to solve everyday problems. In the latter half of this semester, students will focus on where you can find different kinds of equations in the world outside the mathematics classroom, with a focus on interest applications. Finally students will renew their geometry knowledge through a study of triangles, quadrilaterals, area, surface area, and volume. The course concludes with an in-depth look at reading, creating, and interpreting scatterplots.
