Enroll in Grade 7 Mathematics with Dolphin STEM Academy
Mathematics is the study of the patterns around us. In this course, you will learn more
about geometry, statistics, and probability. Geometry is a branch of mathematics that
uses formal methods of thinking to show relationships between points, lines, surfaces,
and solids. Statistics and probability are closely related subjects. In statistics, you will
practice collecting and analyzing numerical data to make decisions. Probability is the
study of the likelihood that an event will occur. For example, what is the likelihood that
you will win a spelling bee if there are 40 participants? Knowing more about these three
disciplines will help you solve problems you encounter every day.
By the end of this course, you will be able to do the following:
Solve problems that involve scale drawings of geometric figures.
Construct geometric shapes with traditional tools and with technology to satisfy given conditions.
Solve real-world and mathematical problems involving angle measure, area, surface area, and volume.
Use data from a random sample to draw inferences about a population.
Compare two populations using their measures of center and measures of variability.
Interpret statistical data, identify the reasoning presented for that data, and
determine if the argument is accurate or valid.
Understand that probability is a measure of the likelihood that a chance event will occur.
Compare expected probability to relative frequency and explain any discrepancies.
Find the probability of a compound event by identifying all the possible outcomes surrounding the event.
Design and use a simulation to generate frequencies for compound events.
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 discussion boards.
For a complete list of general skills that are required for participation in online courses,

the beginning of this course.
Grade 7 Mathematics B is a 0.5-credit course.
Computer with Internet connection and speakers or headphones
Microsoft Word or equivalent
Microsoft Excel or equivalent
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: Geometry
In this unit, you will solve problems involving scale drawings of geometric figures and
draw geometric shapes from a set of given conditions. You will use formulas for area,
surface area, and volume of two- and three-dimensional objects to solve real-world
Unit 2: Statistics
In this unit, you will explore how statistics can be used to gain information about a
population by examining a sample of the population. You will also use data from a
random sample to draw inferences about the characteristics of a population. You will
understand and use measures of center and measures of variability to compare two
populations. Finally, you will work through a course activity on interpreting statistical
data and arguments.
Unit 3: Probability
In this unit, you’ll learn that the probability of a chance event is a number between 0 and
1 that expresses the likelihood of the event occurring. You will compare expected
probability to experimental probability, also called relative frequency. You’ll also find the
probability of a compound event by identifying and organizing all the possible outcomes
surrounding the event. Finally, you’ll use a simulation to generate possible outcomes for
a compound event.
