Progression of Adding & Subtracting Fractions

Description: Adding and subtracting fractions is about more than finding common denominators and following rules. In this progression video, we’ll explore how students build on their understanding of unit fractions, fraction magnitude, and equivalence to develop meaningful strategies for adding and subtracting fractions. Along the way, we’ll examine how visual models and representations help students make sense of the mathematics and move toward flexible, efficient strategies.
