⭐ Connecting Geometric Reasoning to Essential Key Concepts ⭐️
Exploring Geometric Reasoning offers authentic opportunities to revisit the Essential Key Concepts of Number Sense:
B1.2 → Compare and order numbers to 200
Sorting 2D shapes by comparing the number of sides, side lengths, angles, and number of lines of symmetry allows students to revisit and solidify their comparing and ordering skills.

E1.1 sort and identify two-dimensional shapes by comparing number of sides, side lengths, angles, and number of lines of symmetry
E1.2 compose and decompose two-dimensional shapes, and show that the area of a shape remains constant regardless of how its parts are rearranged
E1.3 identify congruent lengths and angles in two-dimensional shapes by mentally and physically matching them, and determine if the shapes are congruent
