Adding Fractions with Unlike Denominators: 2/6 + 3/12

Adding Fractions with Unlike Denominators: 2/6 + 3/12

Resource Type
Developed By
National Center on Intensive Intervention

This video demonstrates how to use the set model to add fractions with unlike denominators. Students need to have the prerequisite conceptual knowledge of finding like denominators before they can apply addition strategies to fractions with unlike denominators. The set model is beneficial for students who do not have automaticity with mentally determining multiples because they can count and move pieces to determine a like denominator.
