Cluster 8: Apply Geometric Concepts

This cluster focuses on geometry and measurement. Students build spatial sense by noticing symmetry and attributes of two-dimensional shapes and using these attributes to identify them. They use tools to draw, sketch, and measure lines, angles, and shapes. Students build connections between geometry and number by generating and analyzing shape patterns to find a rule and by estimating and assessing the reasonableness of their measurements.(See About this Cluster and the Unpacking Document below for more details on this cluster.)
