Adding and Subtracting Fractions
With a pie graph and an infinite blackboard, this video shows how to add, subtract, and simplify fractions. Once he has established the rule, Sal throws the viewer a curve ball with a fraction subtraction problem that results in a negative number.
Fraction - Subtracting Unlike Denominators
These presentations by Monica Yuskaitis are particularly good. In this one, she shows viewers how to deal with subtracting fractions that have unlike denominator, no small task! This is a tricky process, and this PowerPoint takes young mathematicians through in clear and logical steps. Some practice problems are available at the end of the slide show.
Solving Word Problems Involving Subtraction of Similar Fractions without Regrouping
Fourth and fifth graders solve word problems that entail subtraction of similar fractions that have like denominators. They complete magic boxes as a review before participating in a guided lesson on solving similar fraction subtraction problems. The teacher's notes are well-written and contain plenty of applicable practice problems. This resource will serve you well as you strive to meet Common Core math standards.
In this fraction subtraction with common denominators worksheet, students problem solve and calculate the answers to thirty subtraction equations.
Fraction Cookies Bakery
Bake-up some cookie fractions with your class in order to determine improper fractions and mixed numbers. Young bakers calculate cookie orders given on an order form. From their calculations, they write the improper fraction, mixed number, and total amount of whole cookies ordered. Class members then confirm the orders on a confirmation form and code it accordingly. The task may be introduced to the class with the story The Hershey's Milk Chocolate Fractions Book by Jerry Pallotta. A fun and useful way to visualize mixed numbers!
Discover the concept of fractions by using fruit as a model. Scholars discover fractions are part of a whole, similar to the pieces of fruit which are placed in front of them. They then cut up several different types of fruit and discuss what fraction is left before they eat them. A fun activity and a healthy treat!

We are not exactly sure what a Squeeble is, but apparently they love cake and fractions, and your little bakers-turned-mathematicians will also. This app focuses on the basics of fractions including modeling fractions, equivalent fractions, comparing fractions, and simple fraction addition.
Fraction X - Adding Unlike Denominators
Adding fractions with unlike denominators is a difficult process to master. This fine presentation does a terrific job of leading young math whizzes through the steps necessary to perform this calculation. The slides have clear graphics, easy-to-understand text, and many fine examples. The author of this PowerPoint consistently produces excellent math presentations. Highly recommended!

The math monster is at it again, this time stealing all the cars and drivers that were to take part in the cart race. If their addition and subtraction facts are up to the challenge, young mathematicians can win the drivers' freedom and play in the big cart race.
Subtracting Mentally Similar Fractions
Students practice mental subtraction with fractions. Students subtract fractions with like denominators mentally to solve word problems. Students manipulate fraction bars to represent subtraction problems. Students play fraction subtraction games.
Subtract Mixed Numbers With Like Denominators (E)
In this fractions subtraction learning exercise, students solve 14 problems in which mixed numbers with like denominators are subtracted.
New! Partial Fraction Expansion 1
This is the first of three videos on partial fraction expansion. Sal goes over an example that first needs to be divided so that is a proper fraction. He then continues to demonstrate fraction decomposition. At home or in class, this offers a nice review of a real-life math scenario.
Subtraction of Rational Numbers
From common denominators to "hairy problems," your class will benefit greatly from watching Sal exercise his expertise with fractions, algebra, and math in general. Those who have a hard time grasping the concepts of rational numbers could do with a few views of this video, which provides excellent demonstrations of increasingly difficult fraction problems.
Representing a Number as a Decimal, Percent, and Fraction, Part 2
There are two Khan Academy videos on representing numbers as decimals, percents, and fractions. This one shows students how to represent a fraction as a decimal and a percent. Sal demonstrates the process used to convert the fraction 7/8 into a decimal and then a percent. This presentation is very well done and would be great at an independent work station or as homework support.
Partial Fraction Expansion 2
Partial fraction expansion continues to be explored in this video. The example problem shown here is of higher degree polynomial then the one explored in the first Khan Academy video on this subject.
Multiplying Fractions and Mixed Numbers
Here is a great video explaining how to multiply a fraction by a whole number. Sal shows students how to put a whole number over 1 in order to multiply it by a fraction. He simplifies his answer and writes it as a mixed number.
Fraction Subtraction Code Breaker
In this fraction subtraction code breaker worksheet, 5th graders solve 11 fraction subtraction problems with common denominators, then use the answers to break the code.
Fraction Subtraction Worksheet
In this fraction activity, students subtract fractions with unlike denominators. This one-page activity contains 24 problems.
How Do You Subtract Mixed Fractions with Different Denominators by Regrouping?
Are your young mathematicians having trouble with subtracting mixed fractions? Consider this video to supplement your teaching. An instructor explains step-by-step how to subtract mixed fractions with unlike denominators, showing viewers how to create a common denominator and regroup to make subtraction simpler. Although the video could explain more about how to determine the common denominator, it is, overall, clear and effective.
How Do You Subtract a Whole Number from a Fraction?
Follow along as the instructor demonstrates how to subtract a whole number from a fraction. First, she changes the whole number to a fraction. Then she finds the least common denominator of the two fractions. Finally, she does the subtraction.
