# Cluster 5: Extend the understanding of fractions

This cluster extends fraction equivalence and ordering that was first introduced in Grade 3. In Grade 4, students will use visual models and explain why a fraction is equivalent with attention to how the number and size of parts differ even though the amounts themselves are the same. Students compare and order fractions through reasoning about the size of fractions using

benchmark fractions, models, and/or the use of equivalent fractions. Students use greater than, less than, and equal to symbols to record comparisons and are able to justify their conclusions. Student continue the work of equivalent fractions and explore decimal fractions through the use of models. Students use their experience with fractions and place value to make connections between fractions and decimals. (See *About this Cluster* and the *Unpacking Document* below for more details on this cluster.)
