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).
Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).
Correctly name shapes regardless of their orientations or overall size.
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.
