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 and OperationsFractions concepts involved in applying and extending previous understandings of multiplication to multiply a fraction by a whole number. The student multiplies fractions by whole numbers and determines between which two whole numbers the sum of two fractions lies. 
4 
3 
The student response demonstrates a good understanding of the Number and OperationsFractions concepts involved in applying and extending previous understandings of multiplication to multiply a fraction by a whole number. 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 OperationsFractions concepts involved in applying and extending previous understandings of multiplication to multiply a fraction by a whole number. 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 OperationsFractions concepts involved in applying and extending previous understandings of multiplication to multiply a fraction by a whole number. 
0 
The student response contains insufficient evidence of an understanding of the Number and OperationsFractions concepts involved in applying and extending previous understandings of multiplication to multiply a fraction by a whole number to merit any points.
