3 The student response demonstrates a good understanding of the Measurement and Data concepts involved in making a line plot to display a data set of measurements in fractions of a unit and solving problems involving addition and subtraction of fractions by using information presented in line plots. 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 Measurement and Data concepts involved in making a line plot to display a data set of measurements in fractions of a unit and solving problems involving addition and subtraction of fractions by using information presented in line plots. 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 Measurement and Data concepts involved in making a line plot to display a data set of measurements in fractions of a unit and solving problems involving addition and subtraction of fractions by using information presented in line plots.
0 The student response contains insufficient evidence of an understanding of the Measurement and Data concepts involved in making a line plot to display a data set of measurements in fractions of a unit and solving problems involving addition and subtraction of fractions by using information presented in line plots to merit any points.

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