What mastery looks like

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

Beginning

Identify a linear expression that represents a relevant situation.

Developing

Apply the properties of operations to identify equivalent linear expressions with rational coefficients. Write an expression that represents a relevant situation to show how quantities are related.

Proficient

Apply the properties of operations to create equivalent linear expressions with rational coefficients. Write expressions presented in relevant situations in different forms to explain how the quantities are related.

Distinguished

Apply the properties of operations to write, evaluate, and interpret equivalent linear expressions with rational coefficients in multi-step, relevant problems.

The same standard across grades
