United States – Common Core State Standards

  • K – Kindergarten
    • K.G – Geometry
      • Mathematics

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

  • 1 – Grade 1
    • 1.G – Geometry
      • Mathematics

        • 1.G.2 – Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.(Students do not need to learn formal names such as “right rectangular prism.”)

  • 2 – Grade 2
    • 2.G – Geometry
      • Mathematics

        • 2.G.1 – Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. (Sizes are compared directly or visually, not compared by measuring.) Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.

  • 4 – Grade 4
    • 4.G – Geometry
      • Mathematics

        • 4.G.2 – Classify two-dimensional figures based on the presence or absence of parallel or perpendicular lines, or the presence or absence of angles of a specified size. Recognize right triangles as a category, and identify right triangles.
