1. What are the Different Types of Numbers?
Learn all of the different types of numbers: natural numbers, whole numbers, integers, rational numbers, irrational numbers, and real numbers. This video lesson teaches you how to classify any numbers you come across.
2. What Is The Order of Operations in Math? - Definition & Examples
The order of operations is the steps used to simplify any mathematical expression. In this video, learn how to solve problems using these steps and easy tricks to remember them.
3. How to Find the Prime Factorization of a Number
The prime factorization of a number involves breaking that number down to its smallest parts. This lesson will show you two different ways to discover the prime factorization of any number.
4. How to Find the Greatest Common Factor
If the factors of a number are the different numbers that you can multiply together to get that original number, then the greatest common factor of two numbers is just the biggest one that both have in common. See some examples of what I'm talking about here!
5. How to Find the Least Common Multiple
The least common multiple of two numbers is the smallest number that can be divided evenly by your two original numbers. See some examples of what I'm talking about here!
6. How to Build and Reduce Fractions
Fractions are a fundamental part of everyday life. Fractions represent a comparison of a part to the whole. To reduce fractions, we will divide by the greatest common factor, or the GCF.
7. How to Find Least Common Denominators
Finding a Least Common Denominator is an important tool when working with fractions. To find least common denominators, we will use multiples of our numbers.
8. Comparing and Ordering Fractions
Comparing and ordering fractions is way to examine fractions that contain different-sized sets. In order to compare these fractions, you must find a common denominator and make equivalent fractions.
9. Estimation Problems using Fractions
When working with fractions, estimating can save time and effort while getting you very close to the correct answer. In this lesson, we'll learn how to use estimation to quickly solve problems involving fractions.
10. How to Solve Complex Fractions
Did you know fractions can nest within fractions? In this lesson, we'll learn about complex fractions and look at two different methods for solving them.
11. Calculations with Ratios and Proportions
Even if only 99 out of 100 people need to know how to work with ratios, the odds that they'll be useful to you are very high. In this lesson, we'll practice performing calculations with ratios and proportions.
12. What is a Percent? - Definition & Examples
Thinking in terms of pizza is an excellent way to think about percentages. Learn how it can help you understand percentages in this video lesson. You will also learn about the uses of percentages in the real world.
13. Changing Between Decimals and Percents
Watch as we go on a rollercoaster ride in changing from a decimal to percent and then back again. Learn to master this technique so you can get as fast as a rollercoaster going downhill on tests and quizzes when you have to convert between the two.
14. Converting Decimals to Fractions (and Back)
In this lesson, learn how to convert decimals to fractions, and how to convert fractions to decimals. You will cement this knowledge in your mind by working through practice problems with both proper fractions and mixed numbers.
15. Mathematical Sets: Elements, Intersections & Unions
Today we're going to explore mathematical sets, which are surprisingly simple! Sets are just collections of any objects or concepts, also known as elements, that can be related to each other through union or intersection.
16. Ruler Postulate: Definition & Examples
This lesson explains the definition of the ruler postulate. You'll see several examples that use the ruler postulate. Then, you can check your knowledge with a quiz.
17. What is a Fact Family? - Definition & Examples
In this lesson, learn what fact families are and how they work to help you understand that numbers in a fact family are related. Gain a better of understanding of how addition and subtraction work together, and study the relationship between multiplication and division.
18. What is a Multiple in Math? - Definition & Overview
In this lesson we will learn about multiples, a useful concept usually introduced in grammar school multiplication tables. Understanding multiples allows you to find the least common multiple or least common denominator for two or more numbers.
19. What is a Positive Integer? - Definition & Examples
We use positive integers in our everyday lives. We see them everywhere in the world around us. Learn what positive integers are and what you can do with them.
20. Basic Arithmetic: Rules & Concepts
This lesson provides basic rules and concepts of arithmetic, the area of math that involves addition, subtraction, multiplication, and division. This lesson shares details about each operation and how they relate to one another in arithmetic.
21. How to Do Double Digit Multiplication: Steps & Practice Problems
In this video, we'll explore different strategies for multiplying numbers with two digits, including the box, distribution and column methods, and use examples to see how they work.
22. How to Teach Double Digit Multiplication
Need a way to teach double digit multiplication that will work for some students that aren't quite catching on? This lesson goes over several different methods and shows some examples.
23. Double Digit Multiplication Strategies
In this lesson, we will learn three different strategies for double digit multiplication including the traditional method, the box method, and the partial product method.
24. Counting On in Math: Definition & Strategy
Because mental math is a very useful life skill, there are many different concepts. This lesson is designed to define what counting on means. It will also give strategies for helping students understand and have the ability to use counting on in addition.
25. What are Turn Around Facts in Math?
Understanding what turnaround facts are can help you more easily learn addition and multiplication facts. In this lesson, we'll look at turnaround facts and the commutative property of addition and multiplication.
