Cluster 5: Reasoning with their Shapes and Attributes
Students spend time in this cluster reasoning about two-dimensional shapes and their attributes. It is essential that students internalize the attributes of quadrilaterals (particularly rectangles & squares) prior to exploring area and perimeter. (See About this Cluster and the Unpacking Document below for more details on this cluster.)
