4 Score Description M00235 Rubric Student response includes each of the following 4 elements. Reasoning components = 4 points 4 Valid ways to use leftover fabric; 2 of the following: one pillow and one placemat, two placemats, one pillow, one placemat Valid work or explanation for the number of yards needed for two of each item and for the number of yards remaining after two of each item is made Valid work or explanation for how to use leftover fabric in Use 1 Valid work or explanation for how to use leftover fabric in Use 2 Sample Student Response: The first way Lindsey could use the leftover fabric would be to make another pillow and another placemat. She would have 0 yards left over. 27 2(6 3 2) Another way she could use the left over material would be to make a pillow. She would then have 2 yards left over. 27 2(6 3 2) Note: Any other single or combination that results in less than or equal to 5 yards being used is acceptable 3 Student response includes 3 of the 4 elements. 2 Student response includes 2 of the 4 elements. 1 Student response includes 1 of the 4 elements. 0 The response is incorrect or irrelevant.

5 A1 Score Point 4

6 Annotation Anchor Paper 1 Score Point 4 This response receives full credit. The response includes each of the four required elements: Two ways to use the leftover fabric are provided (a pillow and a placemat or make two placemats). Correct work for finding the amount of fabric remaining is shown. A total number of yards needed for 1 of each item is provided ( = 11) and work to find the number of yards needed for two of each item (11 2 = 22) is provided. The number of fabric yards remaining after two of each item are made (27 22 = 5) is provided. An explanation for Use 1 (a pillow and a placemat) is provided (3 + 2 = 5 and five is what we have left). An explanation for Use 2 (two placemats) is provided (2 + 2 = 4 and then we will just have one left).

7 A2 Score Point 4

8 Annotation Anchor Paper 2 Score Point 4 This response receives full credit. The response includes each of the four required elements: Two ways to use the leftover fabric are provided (1 pillow and 1 placemat... or she can make 2 placemats). Correct work for finding the amount of fabric remaining is shown. Work for finding the number of yards remaining after making two curtains (27 12 = 15) is provided. Work to find the number of yards remaining after two pillows are made (15 6 = 9) is provided and the number of yards of fabric remaining after two placemats are made is provided (9 4 = 5). The student used mental math to calculate the total number of yards needed to make 2 curtains (12), 2 pillows (6), and 2 placemats (4), which is acceptable since the complete strategy for finding the amount of fabric remaining is provided by the work. An explanation for Use 1 (1 pillow and 1 placemat) is provided (She can make 1 pillow and 1 placemat and have nothing left). An explanation for Use 2 (2 placemats) is provided (she can make 2 placemats and have 1 yard left).

9 A3 Score Point 3

10 Annotation Anchor Paper 3 Score Point 3 This response receives partial credit. The response includes three of the four required elements: Two ways to use the leftover fabric are provided (a placemat and a pillow... or she could make a placemat). An explanation for Use 1 (a placemat and a pillow) is provided (lindsey could make a placemat and a pillow and have nothing left). An explanation for Use 2 (a placemat) is provided (she could make a placemat and have three yards of fabric left). No work for finding the amount of fabric remaining is provided.

11 A4 Score Point 3

12 Annotation Anchor Paper 4 Score Point 3 This response receives partial credit. The response includes three of the four required elements: Two ways to use the leftover fabric are provided (1 pillow and 1 placemat... or she could make 2 placemats). An explanation for Use 1 (1 pillow and 1 placemat) is provided (which would take 5 yards and leave no fabric left). An explanation for Use 2 (2 placemats) is provided (which would take 4 yards and leave 1 extra yard of fabric). No work for finding the amount of fabric remaining is provided.

13 A5 Score Point 2

14 Annotation Anchor Paper 5 Score Point 2 This response receives partial credit. The response includes two of the four required elements: Correct work for finding the amount of fabric remaining is shown. The number of yards of fabric needed to make two of each item (6 + 6 = 12, = 6, = 4, = 22) and work to find the amount of fabric remaining after two of each item are made and an additional pillow and placemat are made (Than I put in one pillow and that get the fabric to 25 than the only item I could make than was one more placemat. Last I found my answer; 27 and no left over) are provided. The student is adding up all fabric used and stopping when they use of a total of 27 yards. This is a valid strategy. An explanation for Use 1 (one more pillow and one more placemat) is provided (Lindsey can make one more pillow and one more placemat and use all her fabric). Only one way to use the leftover fabric is provided (Lindsey can make one more pillow and one more placemat). Note that two ways to use the leftover fabric are necessary in order to receive credit for element 1. No explanation for a Use 2 is provided.

15 A6 Score Point 2

16 Annotation Anchor Paper 6 Score Point 2 This response receives partial credit. The response includes two of the four required elements: Correct work for finding the amount of fabric remaining is shown The number of yards of fabric needed to make two of each item ( = 22) and the calculation for the amount of fabric remaining after two of each item is made (27 22 = 5) are provided. An explanation for Use 1 (1 pillows and 1 placemat) is provided (There is only one choice to make 5 yards: 1 pillows and 1 placemat). Only one way to use the leftover fabric is provided (1 pillows and 1 placemat). Note that two ways to use the leftover fabric are necessary in order to receive credit for element 1. No explanation for a Use 2 is provided.

17 A7 Score Point 1

18 Annotation Anchor Paper 7 Score Point 1 This response receives partial credit. The response includes one of the four required elements: An explanation for Use 1 (a placemat and a pillow) is provided (she can make a placemat and a pillow... she can use her remaining fabric to make a pillow and a placemat). Only one way to use the leftover fabric is provided (a placemat and a pillow). Two ways to use the leftover fabric are necessary in order to receive credit for element 1. Work shown for finding the amount of fabric remaining is insufficient. Correct work for calculating the amount of fabric remaining after two of each item is made is provided (27 22 = 5 yards). However, work for calculating the amount of yards needed to make two of each item is not shown. Note that both calculations are needed in order to receive credit for this element. No explanation for a Use 2 is provided.

19 A8 Score Point 1

20 Annotation Anchor Paper 8 Score Point 1 This response receives partial credit. The response includes one of the four required elements: Two ways to use the leftover fabric are provided (two more placemats, or one more pillow). No work for finding the amount of fabric remaining is provided. The explanation for Use 1 (two more placements) is incomplete. There is no indication of the amount of fabric that will remain. The explanation for Use 2 (one more pillow) is incomplete. There is no indication of the amount of fabric that will remain.

21 A9 Score Point 0

22 Annotation Anchor Paper 9 Score Point 0 This response receives no credit. The response includes none of the four required elements: Only one way to use the leftover fabric is provided (a placemat and a pillow). Note that although the response may be read as the placemat as the first way and the pillow as the second way, there is no work shown to identify this as the meaning. As the response stands, only one way is provided. Note that two ways to use the leftover fabric are necessary in order to receive credit for this element. No work for finding the amount of fabric remaining is provided. No explanation for Use 1 is provided. No explanation for Use 2 is provided.

23 A10 Score Point 0

24 Annotation Anchor Paper 10 Score Point 0 This response receives no credit. The response includes none of the four required elements: No ways to use the remaining fabric are provided.
