This video is Part Four of the fractions series talks about combining fractions with the SAME denominator. Instructor uses stationary camera and white board for demonstration.

When adding and subtracting fractions, the important thing is to see if the fractions have the same denominator. Discover how to find the least common denominator.

Este video esta perfecto para explicar la suma y resta de las fracciones. Aquí, el profesor enseña dos maneras de resolver los ejemplos que emplea. Muy bien explicado. También, enseña todo el trabajo en la pizarra. (9:29)

This video demonstrates adding and subtracting fractions. (Demonstration is done on a piece of paper.) Examples include division of both numerical and variable expressions. (7:36)

This short video is from Jimmy Chang, who has a master's degree in math and has been a math teacher at St. Pete College for more than eight years. Mr. Chang demonstrates in this video how to add and subtract fractions. (02:45)

In this video, Sal Khan discusses and demonstrates basic addition and subtraction of fractions. Like and unlike denominators are included in his examples. Fraction pies are also used to help explain each fraction. Examples include 1/4 + 1/4, 1/4 +... 1/2, and 1/2 - 1/3. Negative numbers are included at the end of the video. Mr. Khan uses the Paint Program (with different colors) to illustrate his points. Sal Khan is the recipient of the 2009 Microsoft Tech Award in Education. (09:49)[more]

Instructor uses a whiteboard to demonstrate how to add and subtract fractions. In the first part of the video they add with like denominators, then they reduce the fraction. Then they add with unlike denominators, first they find the lowest common mu...ltiple, then convert the fraction, then add them. Then they move on to subtraction with like denominators. Then they give you problems to practice on. Video is good quality and good for all students as a review or initial learning of the topic.[more]

This short video is from Jimmy Chang, who has a master's degree in math and has been a math teacher at St. Pete College for more than eight years. He demonstrates how to solve problems involving addition and subtraction with like denominator, subtrac...tion with unlike denominators, multiplication and division of fractions. (02:39)[more]
