Enroll in Grade 7 Mathematics with Dolphin STEM Academy

Course Overview

Mathematics is the study of the patterns around us. Using the tools in this course, you
will learn more about how to solve problems using expressions and equations. When
you understand how to work with numbers in equations, and how to manipulate
equations, you can more easily solve problems you encounter in everyday life.

Course Goals

By the end of this course, you will be able to do the following:
Identify the constant of proportionality in tables, graphs, diagrams, and descriptions
of proportional relationships.
Use equations to represent proportional relationships.
Use proportional relationships to solve real-world and mathematical problems
involving ratio and percent.
Apply and extend your previous understanding of operations with fractions to add,
subtract, multiply, and divide rational numbers.
Convert a rational number to a decimal number using long division.
Use variables to represent quantities in a real-world or mathematical problem and
write simple expressions, equations, or inequalities to solve the problem.
Use properties of operations to rewrite linear expressions in different forms.

General Skills

To participate in this course, you should be able to do the following:
Complete basic operations with word processing software, such as Microsoft Word and Google Docs.
Communicate through email and participate in discussion boards.

For a complete list of general skills that are required for participation in online courses,
refer to the Prerequisites section of the Plato Student Orientation document, found at
the beginning of this course.

Course Pacing Guide

This course description and pacing guide is intended to help you stay on schedule with
your work. Note that your course instructor may modify the schedule to meet the
specific needs of your class.

Unit 1: Ratios and Proportional Relationships

Summary

In this unit, you will compute unit rates associated with ratios of fractions. You will also
recognize and represent proportional relationships between quantities and identify the
constant of proportionality using various methods. Using proportional relationships, you
will be able solve multistep ratio and percentage problems.

Unit 2: Rational Numbers

Summary

In this unit, you will apply and extend your previous understanding of computations to
add, subtract, multiply, and divide rational numbers. You will represent addition and
subtraction on a horizontal or vertical number line and convert a rational number to a
decimal number using long division. Using these skills, you will solve real-world and
mathematical problems involving the four operations with rational numbers.

Unit 3: Expressions and Equations Involving Rational Numbers

Summary

In this unit, you will apply properties of operations as strategies to add, subtract, factor,
and expand linear expressions with rational coefficients. You will solve multistep real-life
and mathematical problems that include positive and negative rational numbers in any
form. You will use variables to represent quantities in a real-world or mathematical
problem and construct simple equations and inequalities to solve problems involving the
quantities.
