In this cluster, students build and on their understanding of unit fractions, relative size of fractions, and fraction equivalence to reason and compute with numbers. Students compose fractions from unit fractions and decompose fractions into unit fractions (including mixed numbers) representing their understanding with visual models and number sentences. Using fraction knowledge and prior understanding of whole-number operations, students explore and develop fraction computation
strategies. (See About this Cluster and the Unpacking Document below for more details on this cluster.)
