Georgia 2.GSR.7.1
The Standard
Describe, compare and sort 2-D shapes including polygons, triangles, quadrilaterals, pentagons, hexagons, and 3-D shapes including rectangular prisms and cones, given a set of attributes.
Georgia's K-12 Mathematics Standards · Draw and partition shapes and other objects with specific attributes, and conduct observations of everyday items and structures to identify how shapes exist in the world.

What This Standard Means
What Students Need to Do
- Students name, describe, compare, and sort flat and solid shapes using visible attributes. They use details such as sides, vertices, faces, edges, and curved surfaces rather than color or size.
What Mastery Looks Like
- Students correctly name common flat and solid shapes in different sizes and positions. They sort shapes by sides, vertices, faces, edges, or curved surfaces and explain why each shape belongs.
Common Misconceptions
- Students may sort by color, size, or direction instead of geometric attributes. They may think a rotated shape changes its name or confuse a solid’s flat faces with the solid itself.
How to Assess It
- Give students cards showing a triangle, pentagon, hexagon, rectangular prism, and cone. Ask them to sort the cards into two groups, label each group, and explain their rule using attributes.

Ways to Teach It
Students sort paper shapes and solid models into labeled hoops, then justify each placement using sides, vertices, faces, edges, or curved surfaces.
Ask, “How are a pentagon and hexagon alike and different?” Students write two comparisons using shape attributes.
Play shape riddle bingo by calling clues such as, “I have six sides,” while students cover matching pictures.
Students photograph or sketch classroom objects shaped like cones or rectangular prisms, then label the attributes that support each match.
