### 1. What are Variables in Math? - Definition & Examples

Variables are seen in almost all math applications beginning with algebra. In this lesson, learn why variables are not something to be afraid of or some concept that is impossible to grasp. Learn what makes them so useful to mathematicians and to you.

### 2. Associative Property Lesson for Kids

Did you know that you can sometimes move numbers around in math problems, but the answer doesn't change? Let's look at why this happens as we explore the associative property in this lesson.

### 3. Commutative Property: Lesson for Kids

Have you ever noticed that sometimes you have two separate math problems with the same exact answer? How can that be? In this lesson, we will explore just one of the reasons why this is possible in math: the commutative property.

### 4. Addition Property of Equality: Definition & Example

After watching this video lesson, you should be able to use the addition property of equality to help you solve problems. In addition, you can learn the formula for this property.

### 5. Multiplication Property of Equality: Definition & Example

After watching this video lesson, you will learn to use the multiplication property of equality to help you solve problems in math. You will also learn the formula for this property.

### 6. Defining, Translating, & Solving One-Step Equations

Watch this video lesson to learn how you can write a simple math equation when you are given a word problem. Learn how to translate words into math symbols. Learn the shortcuts to remember.

### 7. Solving Problems With More Than One Operation: Lesson for Kids

Solving math problems with one operation is pretty easy, but moving on to problems with more than one operation can be just as easy. You just need to know the strategies!

### 8. Solving Multi-Step Word Problems with the 4 Operations: Lesson for Kids

Word problems are like puzzles. You need to identify the things that you know and determine how to find the answer using those facts. The things that we do know are called data, and the things that we don't are called variables.
