  • Ways to reduce and build fractions
  • How to determine the least common denominator
  • Converting improper fractions to mixed numbers and vice versa
  • Addition and subtraction with like and unlike fractions and mixed numbers
  • How to multiply and divide fractions and mixed numbers

These lessons are short, about five minutes long on average, and you can watch them from anywhere you've got Internet access. Lesson quizzes evaluate your learning, and clickable links that take you back to key points of the lessons make review easy. You can print a sheet of quiz questions to use for offline study.

NES Math: Fractions Objectives

In several states, passing the NES Math test is one of the requirements for certification as a secondary-level math teacher. All questions are multiple-choice, requiring you to read a question or solve a problem and select the correct response from four options. The test is computer-based. The lesson quizzes and the chapter exam in this study guide are in this format as well, so they provide experience as well as a way to assess your learning.

The NES Math test has five content domains. The questions regarding fractions are in the content domain on Mathematical Processes and Number Sense, which accounts for 19% of the test's total scoring.

7 Lessons in Chapter 2: NES Math: Fractions
How to Build and Reduce Fractions

1. 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.

How to Find Least Common Denominators

2. 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.

Changing Between Improper Fraction and Mixed Number Form

3. Changing Between Improper Fraction and Mixed Number Form

Improper fractions and mixed numbers are two different types of fractions. They both have different purposes when using fractions in a problem. In this lesson, you will learn how to convert between these two different forms.

How to Add and Subtract Like Fractions and Mixed Numbers

4. How to Add and Subtract Like Fractions and Mixed Numbers

When adding and subtracting fractions, you must be sure to have a common denominator. Once you have a common denominator, you just add or subtract your numerators and then your whole numbers. Learn how in this lesson.

How to Add and Subtract Unlike Fractions and Mixed Numbers

5. How to Add and Subtract Unlike Fractions and Mixed Numbers

Simple fraction arithmetic gets a little more complicated when our denominators don't match. In this lesson, we'll learn how to add and subtract unlike fractions. Then, we'll do the same with mixed numbers.

Multiplying Fractions and Mixed Numbers

6. Multiplying Fractions and Mixed Numbers

Multiplying fractions is much more straightforward than adding, subtracting or dividing fractions. In this lesson, learn how it works. We'll also learn how to multiply mixed numbers.

Dividing Fractions and Mixed Numbers

7. Dividing Fractions and Mixed Numbers

Dividing fractions and mixed numbers? It sounds daunting, but it's not as tricky as it sounds. In this lesson, we'll learn how to divide fractions and mixed numbers.
