ScoreDescription
4 The student response demonstrates an exemplary understanding of the Ratios and Proportional Relationships concepts involved in recognizing and representing proportional relationships between quantities.

4
3 The student response demonstrates a good understanding of the Ratios and Proportional Relationships concepts involved in recognizing and representing proportional relationships between quantities. 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 Ratios and Proportional Relationships concepts involved in recognizing and representing proportional relationships between quantities. 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 Ratios and Proportional Relationships concepts involved in recognizing and representing proportional relationships between quantities.
0 The student response contains insufficient evidence of an understanding of the Ratios and Proportional relationships concepts involved in recognizing and representing proportional relationships between quantities to merit any points.
