4
3 The student response demonstrates a good understanding of the Numbers and Operations—Fractions concepts involved in applying and extending the previous understandings of multiplication to multiply a fraction or whole number by a fraction. 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 Numbers and Operations—Fractions concepts involved in applying and extending the previous understandings of multiplication to multiply a fraction or whole number by a fraction. 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 only a minimal understanding of the Numbers and Operations—Fractions concepts involved in applying and extending the previous understandings of multiplication to multiply a fraction or whole number by a fraction.
0 The student response contains insufficient evidence of an understanding of the Numbers and Operations—Fractions concepts involved in applying and extending the previous understandings of multiplication to multiply a fraction or whole number by a fraction to merit any points.
