Common Core: Geometry
1.G.A1
Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
October 1, 2018K.G.A1
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.
October 1, 2018K.G.B6
Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”
October 1, 2018K.G.B5
Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.
October 1, 2018K.G.B4
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).
October 1, 2018K.G.A3
Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).
