Scoring Guide and Sample Student Work
Select a score point in the table below to view the sample student response.

ScoreDescription
4 The student response demonstrates an exemplary understanding of the Number System concepts involved in solving real-world and mathematical problems involving the four operations with rational numbers. The student converts a percent to a fraction and adds, subtracts, multiplies, and divides fractions to solve a real-world problem.
4
3 The student response demonstrates a good understanding of the Number System concepts involved in solving real-world and mathematical problems involving the four operations with rational 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 System concepts involved in solving real-world and mathematical problems involving the four operations with rational 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 System concepts involved in solving real-world and mathematical problems involving the four operations with rational numbers.
0 The student response contains insufficient evidence of an understanding of the Number System concepts involved in solving real-world and mathematical problems involving the four operations with rational numbers to merit any points.

Note: There are 2 sample student responses for Score Point 4.
