4	The student response demonstrates an exemplary understanding of the Number and Quantity concepts involved in rewriting expressions involving radicals and rational exponents. The student evaluates expressions for specific values of a variable and simplifies expressions representing distance and area.
4
3	The student response demonstrates a good understanding of the Number and Quantity concepts involved in rewriting expressions involving radicals and rational exponents. Although there is significant evidence that the student was able to recognize and apply the concepts involved, some aspect of the response is flawed. As a result, the response merits 3 points.
2	The student response demonstrates a fair understanding of the Number and Quantity concepts involved in rewriting expressions involving radicals and rational exponents. While some aspects of the task are completed correctly, others are not. The mixed evidence provided by the student merits 2 points.
1	The student response demonstrates a minimal understanding of the Number and Quantity concepts involved in rewriting expressions involving radicals and rational exponents.
0	The student response contains insufficient evidence of an understanding of the Number and Quantity concepts involved in rewriting expressions involving radicals and rational exponents to merit any points.
