Georgia's Achievement Level Descriptors. The levels are cumulative: each includes the ones before it. Proficient is on grade level.

Beginning: Classify polygons based on the number of sides. Describe attributes of a specific polygon.
Developing: Classify polygons (triangles, quadrilaterals, pentagons, hexagons, and octagons) based on angles, side lengths, symmetry, congruence, and the presence or absence of parallel lines. Given an image of a right rectangular prism packed with unit cubes, determine the volume of the prism. Determine the volume of a right rectangular prism by using the height and the area of the base.
Proficient: Compare and contrast polygons (triangles, quadrilaterals, pentagons, hexagons, and octagons) based on angles, side lengths, symmetry, congruence, and the presence or absence of parallel lines. Analyze the properties of categories of shapes to draw conclusions about the properties of shapes in subcategories of the original categories. Determine the volume of a right rectangular prism by using the height and the area of the base to solve authentic mathematical problems.
Distinguished: Explain how the volume of a right rectangular prism can be found by multiplying the height by the area of the base to solve authentic mathematical problems.
