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

Beginning: Given a visual representation, identify a unit fraction and an equivalent fraction. Given a visual representation, compare two unit fractions within a contextual situation.
Developing: Given a visual representation, identify and describe a non-unit fraction as multiple copies of a unit fraction. Given a visual representation, compare two unit fractions and record the comparison using <, >, or =. Given a fraction, including fractions greater than one, represent the fraction with a visual representation. Given a visual representation, generate an equivalent fraction.
Proficient: Use multiple representations to identify and describe a non-unit fraction as multiple copies of a unit fraction. Compare two unit fractions and record the comparison using <, >, or =. Given a fraction, including fractions greater than one, represent the fraction in multiple ways. Generate equivalent fractions.
Distinguished: Solve complex or multi-step real-life problems by representing and comparing fractions and making connections between different representations.
