Systems of Equations
	Excellent 4 pts	Good 3 pts	Fair 2 pts	Poor 1 pts
Solving Systems by Graphing	Excellent Student can accurately graph and find the point of intersection for a variety of situations with very few errors. Student can explain the situation in detail and make predictions about changes.	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.	Fair Student can graph and find the point of intersection most of the time. Student has some understanding of the interpretation of the solution.	Poor Student is unable to graph and find the point of intersection at least half of the time. Student cannot interpret the solution.
Solving Systems by Substitution	Excellent Student can accurately make substitutions, use distributive property and find a solution in a variety of situations with very few errors. Student can explain the situation in detail and make predictions about changes.	Good Student can almost always make substitutions, use distributive property and find a solution.
