Cluster 7: Classifying Quadrilaterals

In this cluster, students are expected to classify quadrilaterals into a hierarchy to construct classifications based
on the hierarchy. Classifying quadrilaterals into a hierarchy is a higher level of geometric thought. Even though students identified triangles and quadrilaterals in fourth grade, they may need additional experiences with sorting shapes and discussing the relationships between shapes based on attributes. (See About this Cluster and the Unpacking Document below for more details on this cluster.)
