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 Number Sense and Operations concepts involved in accurately and efficiently adding and subtracting decimals and dividing whole numbers. The student uses computations to solve realworld problems including dividing a threedigit whole number by a twodigit whole number and adding decimals. 
4 
3 
The student response demonstrates a good understanding of the Number Sense and Operations concepts involved in accurately and efficiently adding and subtracting decimals and dividing whole numbers. 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 Sense and Operations concepts involved in accurately and efficiently adding and subtracting decimals and dividing whole numbers. 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 Sense and Operations concepts involved in accurately and efficiently adding and subtracting decimals and dividing whole numbers. 
0 
The student response contains insufficient evidence of an understanding of the Number Sense and Operations concepts involved in accurately and efficiently adding and subtracting decimals and dividing whole numbers to merit any points.
