Scoring Guide and Sample Student Work

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

Score	Description
3	The student response demonstrates an exemplary understanding of the Number & Operations in Base Ten concepts involved in fluently adding and subtracting within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. The student correctly adds and subtracts within 1000 and demonstrates a relationship between addition and subtraction with equations.
3
2	The student response demonstrates a good understanding of the Number & Operations in Base Ten concepts involved in fluently adding and subtracting within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. 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 2 points.
1	The student response demonstrates a minimal understanding of the Number & Operations in Base Ten concepts involved in fluently adding and subtracting within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. 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 Number & Operations in Base Ten concepts involved in fluently adding and subtracting within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction to merit any points.
