1. What are Whole Numbers? - Definition & Examples
In this lesson, we will learn about whole numbers , including what they are and what distinguishes them from other types of numbers. We'll also take a look at a few things about whole numbers that sometimes trip students up.
2. Using the Number Line to Compare Decimals, Fractions, and Whole Numbers
Watch this video lesson to learn how useful the number line can be when you need to compare two different numbers, be they whole numbers, decimals or even fractions. Learn how to plot these numbers on the number line so you can compare them.
3. Rounding Numbers to the Nearest 1000, 10,000 & 100,000
After watching this video lesson, you will be able to round larger numbers like a pro. Learn what the cutoff numbers are for rounding up and down to the nearest thousand, ten thousand and hundred thousand.
4. Rounding Whole Numbers on a Number Line
In this lesson, you will learn how to round to the nearest hundred and thousand on a number line. You will also learn how to plot a number on a number line and will be given examples to further your knowledge on this subject.
5. How to Use Exponential Notation
Exponential notation is a mathematical method for writing longer multiplication problems in a simplified manner. This lesson will define how to work with exponential notation and give some examples of how it is used.
6. The Commutative Property: Definition and Examples
There are three major properties that deal with the addition and multiplication of numbers. One of those properties is the commutative property. This lesson will define and give examples of the commutative property and how it works.
7. The Associative Property: Definition and Examples
There are three basic number properties that help to form the backbone of algebra. One of those properties is the associative property. This lesson will define the associative property and give some examples of how it works.
8. Distributive Property: Definition, Use & Examples
After completing this lesson, you will be able to state the distributive property and apply it to various types of problems. You will also be able to accurately perform the mathematical operations that are involved with the distributive property.
9. Using Mental Math to Solve One-Step Problems
After reading this lesson, you'll know how you can solve one-step math problems without having to write anything down. Learn the technique you can use to help you solve the problem in your head.
10. Using Mental Math to Solve Two-Step Problems
For this lesson you will learn how to solve two step word problems using addition and subtraction. We will explore ways to solve simple problems by identifying key information in the word problem.
