Adding and Subtracting Fractions with Like Denominators

This video tutorial covers the basics of adding and subtracting fractions for Grade 4 students using the Go Math curriculum. It begins with an introduction to fractions, followed by a practical problem involving a poster. The video addresses common mistakes, such as incorrectly adding denominators, and explains the concept of common denominators. It concludes with several practice problems to reinforce the concepts taught.
