Introduction

If you are a student or a parent of a fifth-grader, you might have heard about Go Math. It is a popular math curriculum used in many schools across the United States. In this article, we will be discussing one of the lessons from Chapter 9 of the Go Math curriculum, Lesson 9.6.

Lesson 9.6 Overview

Lesson 9.6 focuses on adding and subtracting fractions with unlike denominators. It is an important lesson as it builds upon the previous lessons that covered adding and subtracting fractions with like denominators. In this lesson, students will learn how to find the common denominator and then add or subtract the fractions.

What is a Common Denominator?

Before we dive into adding and subtracting fractions with unlike denominators, let’s understand what a common denominator is. A common denominator is a number that is a multiple of all the denominators in the fractions. For example, if we have two fractions with denominators 3 and 5, the common denominator would be 15.

Adding Fractions with Unlike Denominators

To add fractions with unlike denominators, we need to find the common denominator first. Once we have the common denominator, we can add the numerators of the fractions and simplify the answer if needed. For example, if we want to add 3/4 and 1/3, we would first find the common denominator, which is 12. Then we would convert the fractions to have a denominator of 12 and add the numerators. The answer would be 13/12.

Subtracting Fractions with Unlike Denominators

Subtracting fractions with unlike denominators follows a similar process. We first find the common denominator and then subtract the numerators of the fractions. For example, if we want to subtract 5/6 from 2/9, we would first find the common denominator, which is 18. Then we would convert the fractions to have a denominator of 18 and subtract the numerators. The answer would be -17/18.

Practice Makes Perfect

Like any math concept, practice is key to mastering adding and subtracting fractions with unlike denominators. The Go Math curriculum offers many practice problems and exercises for students to work on. Parents can also find additional resources online to help their children practice.

Conclusion

In conclusion, Lesson 9.6 of the Go Math curriculum teaches students how to add and subtract fractions with unlike denominators. It is an important lesson that builds upon previous concepts and prepares students for more advanced math topics. By understanding the concept of finding a common denominator, students will be able to confidently solve problems involving fractions with unlike denominators.
