⭐ Connecting Geometric Reasoning to Essential Key Concepts ⭐️
Exploring Geometric Reasoning offers authentic opportunities to revisit the Essential Key Concepts of Number Sense:
B1.3 → Compare and order numbers to 50
Sorting 2D shapes and 3D objects by comparing attributes allows students to revisit and solidify their comparing and ordering skills (e.g., grouping 2D shapes by number of sides, grouping 3D objects by number of vertices).

E1.1 sort three-dimensional objects and two-dimensional shapes according to one attribute at a time, and identify the sorting rule being used
E1.2 construct three-dimensional objects, and identify two-dimensional shapes contained within structures and objects
E1.3 construct and describe two-dimensional shapes and three-dimensional objects that have matching halves
