CCSS.MATH.CONTENT.K.G.A.1 - Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.

CCSS.MATH.CONTENT.K.G.A.2 - Correctly name shapes regardless of their orientations or overall size.

CCSS.MATH.CONTENT.K.G.A.3 - Identify shapes as two-dimensional (lying in a plane, "flat") or three-dimensional ("solid").

CCSS.MATH.CONTENT.K.G.B.4 - Analyze and compare two- and three-dimensional shapes, in different sizes and orientations, using informal language to describe their similarities, differences, parts (e.g., number of sides and vertices/"corners") and other attributes (e.g., having sides of equal length).

CCSS.MATH.CONTENT.K.G.B.5 - Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.

CCSS.MATH.CONTENT.K.G.B.6 - Compose simple shapes to form larger shapes. For example, "Can you join these two triangles with full sides touching to make a rectangle?"
