Scoring Guide and Sample Student Work

Select a score point in the table below to view the sample student response.

Score	Description
4	The student response demonstrates an exemplary understanding of the Expressions and Equations concepts involving solving real-world problems by writing and solving equations of the form x+p=q and px=q.
4
3	The student response demonstrates a good understanding of the Expressions and Equations concepts involving solving real-world problems by writing and solving equations of the form x+p=q and px=q. 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 Expressions and Equations concepts involving solving real-world problems by writing and solving equations of the form x+p=q and px=q. 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 Expressions and Equations concepts involving solving real-world problems by writing and solving equations of the form x+p=q and px=q.
0	The student response contains insufficient evidence of an understanding of the Expressions and Equations concepts involving solving real-world problems by writing and solving equations of the form x+p=q and px=q to merit any points.
