This video explains how to add fractions with different denominators. Several examples are used to help reinforce the concept. The instructor, in his conversational tone, uses a black screen as a 'chalkboard.' Different colors and pictures are used ...for clarification. (04:05)[more]

John, a math teacher, uses a small whiteboard in this short two-minute tutorial to demonstrate how to add fractions with different denominators. The video goes step-by-step and is easy to understand.

In this video they show how to add fractions with unlike denominators. The LCD or lowest common denominator is found and the fractions are converted. The LCD method is shown to students. Then the fractions are added. At the end of the video there are... problems for the students to practice on. Video is good quality and good for all students as a review or initial learning of the topic.[more]
