Enter rubric title Enter rubric description
	Novice (N/A)	Proficient (N/A)	Advanced (N/A)	Exemplary (N/A)
Equations Enter criteria description	Novice Eight equations are written in standard, vertex and factored forms. Some minor errors are present.	Proficient Eight equations are written in standard, vertex and factored forms. The equations are identified correctly.	Advanced More than eight equations are written in standard, vertex and factored forms. The equations are indentified correctly.	Exemplary More than eight equations are written. The equations are written in all three forms.
Opening of the Parabola Enter criteria description	Novice Minor errors exist when the student determines if the parabola opens upward or downward direction.	Proficient No errors exist when the student determines if the parabola opens in an upward or downward direction.	Advanced No errors exist when the student determines if the parabola opens in an upward or downward direction. The student provides justification for his/her thinking.	Exemplary No errors exist when the student determines if the parabola opens in an upward or downward direction. The student can provide a rationale for his/her thinking by making a reference to each equation.
Axis of Symmetry Enter criteria description	Novice The student determines the axis of symmetry for each equation and minor errors exist.	Proficient The axis of symmetry is determined for each equation and no errors exist.	Advanced The axis of symmetry is determined for every equation. No errors exist and the student shows some of the steps for determining the axis of symmetry.	Exemplary The axis of symmetry is determined for every equation. No errors exist and the student shows all steps for determining the axis of symmetry.
Vertex	Novice An attempt is made to determine the vertex for each equation, but some minor errors exist.	Proficient The vertex is determined for each equation and no errors exist.	Advanced The vertex is determined for each equation and no errors exist. Some steps for determining the vertex are shown.	Exemplary The vertex is determined for each equation and no errors exist. All steps for determining the vertex are shown.
Five Points on the Graph	Novice An attempt is made to determine 5 points on the graph. Minor errors exist.	Proficient Five points on the graph are listed. There are no errors.	Advanced More than five points on the graph are listed. No errors exist.	Exemplary More than five points on the graph are listed with no errors. The student shows how to compute the points.
Questions	Novice An attempt is made to answer the questions. The student's response does not adequately answer the question.	Proficient All questions are answered correctly. The student response provides some evidence of mathematical thinking and reasoning.	Advanced All questions are answered correctly. The student response provides evidence of mathematical thinking and reasoning. It may contain examples to justify thinking.	Exemplary All questions are answered correctly. The student response is specific and detailed. It provides strong evidence of mathematical thinking and reasoning.
