Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres).

• 2. Correctly name shapes regardless of their orientations or overall size.

  Suggested tag: cc-km-g-2

• 3. Identify shapes as two-dimensional (lying in a plane, “flat”) or three-dimensional (“solid”).

  Suggested tag: cc-km-g-3

Analyze, compare, create, and compose shapes.

• 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).

  Suggested tag: cc-km-g-4

• 5. Model shapes in the world by building shapes from components (e.g., sticks and clay balls) and drawing shapes.

  Suggested tag: cc-km-g-5

• 6. Compose simple shapes to form larger shapes. For example, “Can you join these two triangles with full sides touching to make a rectangle?”
