Select a score point in the table below to view the sample student response.

ScoreDescription
2 The student response demonstrates an exemplary understanding of the Geometry concepts involved in partitioning shapes into parts with equal areas and expressing the area of each part as a unit fraction of the whole. The student divides a rectangle into equal parts and writes a fraction to represent the area of one part.
2
1 The student response demonstrates a fair understanding of the Geometry concepts involved in partitioning shapes into parts with equal areas and expressing the area of each part as a unit fraction of the whole. While some aspects of the task are completed correctly, others are not. The mixed evidence provided by the student merits 1 point.
0 The student response contains insufficient evidence of an understanding of the Geometry concepts involved in partitioning shapes into parts with equal areas and expressing the area of each part as a unit fraction of the whole to merit any points.

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