 Standard 5.Understands and applies basic and advanced properties of the concepts of geometry
  Level II [Grade 3-5]
   Benchmark 2
Understands basic properties of figures (e.g., two- or three-dimensionality, symmetry, number of faces, type of angle)
    Knowledge/skill statement 5
Understands that objects have a defining number and types of angles
Related assessment item(s):

Use manipulatives and knowledge of 2-dimensional shapes to create figures (T1) - D
Performance expectation(s):
    Develops definitions of classes of shapes such as triangles and pyramids (M)

Compares, contrasts, and describes plane and solid figures and shapes using their attributes (e.g., classification of angles) (C5)

Identifies figures by their properties (e.g., no right angles) (S1)

3.G.1 Understand that shapes in different categories (e.g., rhombuses,rectangles, and others) may share attributes (e.g., having four sides),and that the shared attributes can define a larger category (e.g.,quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

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.

5.G.3 Understand that attributes belonging to a category of two-dimensional figures also belong to all subcategories of that category. For example, all rectangles have four right angles and squares are rectangles, so all squares have four right angles.

5.G.4 Classify two-dimensional figures in a hierarchy based on properties.
