Adding and Subtracting Fractions

This video tutorial covers adding and subtracting fractions with like denominators, working with mixed numbers, and fractions greater than one. It emphasizes using models and number lines to build conceptual understanding before moving to traditional algorithms. The tutorial also includes real-world examples and questions to help students apply their knowledge.
