Adding and Subtracting Fractions with Like Denominators

This video tutorial covers adding and subtracting fractions with like denominators. It begins with an introduction to the concept, followed by examples using pies and pizza to demonstrate the process. The video includes guided practice sessions for both adding and subtracting fractions, allowing students to apply what they've learned. The tutorial emphasizes the importance of having the same denominators and focuses on manipulating numerators to find the solution.

What does it mean when fractions have like denominators?

• Their numerators are the same

• Their denominators are different

• Their denominators are the same

• They cannot be added or subtracted
