Elementary Math Help
In this section, you will find explanations to many mathematical processes learned in elementary school, grades 1-8. The navigation (on the left) is set up to progress in a general order of how topics are learned; however, you (students, parents, and tutors) may find it more helpful to simply look for the topic you need help with. Nearly every main page has sub-pages, because nearly every general topic can be explained more thoroughly. Many of the pages have quizzes (multiple choice, fill in the blank) for students to practice the skill or skills being discussed. Below, you will find a brief description of each page, as well as links to the page and subpages.
Addition is the first and most important lesson for beginning math students. This lesson explains
basic types of addition. First, we cover adding one digit numbers. Then we move onto two digit
numbers, with and without carrying. We’ve included illustrations to help explain these concepts,
and practice problems for students to work with.
The opposite of addition, subtraction is the process of “taking away” one number from another.
This group of lessons covers different types of subtraction, starting with the simplest: subtracting
one digit numbers. We then walk through subtraction involving two digit numbers, first
subtraction without borrowing, then subtraction with borrowing.
You can think of multiplication as a quick way of adding multiple numbers at once. Our
multiplication lessons include an overview and times table you can use for multiplication
practice. Once you’re comfortable multiplying one and two digit numbers, we can help you
If you need a quick primer on division, we’ve got you covered. This lesson introduces the
concept of division and walks you through some basic division problems.
Long division is an useful way to tackle division problems you can’t solve in your head. Our
lessons on long division explain the concept in a step-by-step way. Work through a detailed
decimals, and long division with remainders.
These lessons introduce place value of digits in numbers—both whole and decimal. Practice
naming them and identifying digits with our examples. Then we move on to rounding numbers,
which is based on place value of each digit. Rounding is taught using terms such as “round to
the nearest hundred.”
Do you know the difference between a factor and a multiple? Read on for simple definitions.
This comprehensive set of lessons introduces you to the subject of fractions. Learn how to
understand and evaluate fractions with our lessons on comparing fractions, expanding and reducing fractions, and finding the common denominator of a fraction. If you’re having trouble solving problems involving fractions, we can help explain how to add or subtract fractions, multiply fractions, and divide fractions. We also cover special types of fractions, including mixed numbers and improper fractions.
How do you turn a fraction into a decimal, or a decimal into a percent? This lesson on
conversions explains a variety of methods, and number conversion is easier than it looks. These
methods all involve basic operations or simple algebra.
Need to know the difference between English and metric measurements? Looking for a list of
common metric prefixes? This lesson provides an overview of different measurement systems and how to convert between them.
Understanding different shapes is an important step for elementary students. This lesson
describes all of the basic shapes that early math students should know. We define and illustrate
each shape, and describe the differences between them.
Area and perimeter are calculations made on different shapes. Learn how they’re defined in this
lesson, then go into more detail on our complete lessons on finding the areas of shapes and
This lesson introduces how to read an analog clock and describes how to read the hour hand
and minute hand. Learn about the difference between AM and PM, as well as how to figure out
elapsed time (how much time has passed).
Learn how to recognize and count money in this set of lessons. The first lesson includes images
of all US currency and tips for counting money. From there, you can move onto more detailed
This lesson introduces the difference between positive numbers (having something) and
negative numbers (lacking something). Learn the proper notation for negative numbers (how to
write a negative number) and how to count negative numbers. Other lessons go into more detail
well as how to deal with negative fractions, decimals and percents.
This lesson introduces the three concepts behind averaging numbers: mean, median, and
mode. Learn how these concepts are different from each other, as well as how to calculate each
with a series of numbers.
In these lessons, you’ll receive an introduction to solving equations. We begin with “finding the
missing number,” then move on to solving equations with variables (such as x or y), as well
