National Center on Intensive Intervention

This series of 22 videos provides brief instructional examples for supporting students who need intensive instruction in the area of fractions. Within college- and career-ready standards fractions are typically taught in Grades 3-5. Computation of fractions covers skills focused on building fractions from unit fractions—applying and extending operations of whole numbers. These videos may be used as these concepts are introduced, or with students in higher grade levels who continue to struggle with the concepts. Special education teachers, math interventionists, and others working with struggling students may find these videos helpful.
