Solving Systems by Graphing
Poor
Student is unable to graph and find the point of intersection at least half of the time. Student cannot interpret the solution.
Fair
Student can graph and find the point of intersection most of the time. Student has some understanding of the interpretation of the solution.
Good
Student can almost always graph and find the point of intersection for a variety of situations and can interpret the solution. Student can basically explain the situation and make some predictions about changes.
Excellent
