The following 12 Sample Student Responses represent a range of score points.

Score for Sample Student Response #1: Rubric Score 1

Annotation: This response demonstrates a minimal understanding and analysis of the problem. The representation is correct; the houses and garages are drawn with the correct orientations. The student tries to identify, rather than fully describe, the transformations. Reflection is correctly identified but lacks the line of reflection for a full description. "From B to C was a trasition" is incorrect. Despite having a correct representation, without at least some understanding of both reflection and rotation, the response demonstrates minimal understanding of transformations. Compare to Anchor Paper #2.

Score for Sample Student Response #2: Rubric Score 3

Annotation: This response demonstrates a complete understanding and analysis of the problem. The representation is correct with each house and garage correctly oriented. The first transformation is correctly described as a reflection over the clearly labeled line segment HI. The second transformation is correctly described as a translation "to the right a few units, and then rotated 90° at point K" with the point of rotation K clearly labeled. The third transformation is correctly described as a reflection over the clearly labeled line segment SM. The student provides full descriptions of all the transformations, demonstrating application of a reasonable strategy to solve the problem.

Score for Sample Student Response #3: Rubric Score 2

Annotation: This response demonstrates a conceptual understanding and analysis of the problem. The representation is correct; the houses and garages are drawn with the correct orientations. The student identifies the transformations from A to B and C to D as reflections, but fails to provide the line of reflection. The student correctly describes the transformation from B to C as a 90° rotation. (Rotation suffices as the only transformation needed for the reproduction of the house and garage from B to C because the point of rotation could exist outside the shape or lot.) While a correct description of rotation has been provided, reflection was only identified and lacks a developed or complete description. Compare to Anchor Paper #4.

Score for Sample Student Response #4: Rubric Score 3

Annotation: This response demonstrates a complete understanding and analysis of the problem. The representation is correct with houses and garages correctly oriented. The student provides a correct description for the transformations from lot A to lot B and lot C to lot D. "Reflected over the edge of lot B...reflected over the edge of lot D" correctly identifies reflection and provides the lines of reflection. The student gives a correct description for the transformation from lot B to lot C. "Rotated 90° and then slid over the edge of lot C" describes the translation ("slide" is an acceptable term identifying translation) and rotation.

Score for Sample Student Response #5: Rubric Score 1

Annotation: This response demonstrates minimal understanding and analysis of the problem. The representation is correct; the houses and garages are drawn with the correct orientations. However, while the student tries to discuss the drawing, no description is provided for the transformations required to reproduce the houses and garages.

Score for Sample Student Response #6: Rubric Score 2

Annotation: This response demonstrates a conceptual understanding and analysis of the problem. The representation is correct with all the houses and garages correctly oriented. The student correctly identifies the transformations from lot A to lot B and lot C to lot D as reflections ("flip" and "mirrored"). However, the response lacks a full description because no line of reflection is given. The transformation from lot B to lot C is correctly identified as a rotation, but the student fails to provide the degree of rotation. Compare to Anchor Paper #3.

Score for Sample Student Response #7: Rubric Score 2

Annotation: This response demonstrates a conceptual understanding and analysis of the problem. The representation is correct with each house and garage correctly oriented. The student correctly identifies the transformations from A to B and C to D as reflections ("reflect" and "flip"). However, the response lacks a full description because no line of reflection is identified. The transformation from B to C is correctly identified as a rotation and translation ("slide"), but the student neglects to provide the degree of rotation, a minimal requirement for a full description of rotation. The response lacks a full description of the correctly identified transformations.

Score for Sample Student Response #8: Rubric Score 1

Annotation: This response demonstrates a minimal understanding and analysis of the problem. The representation is correct; the houses and garages are drawn with the correct orientations. Whether the student understands the correct application of rotation for the transformation from lot B to lot C or if he/she believes rotation was used for all three transformations is unclear. "By rotation the houses and the garage is the same." Compare to Anchor Paper #2.

Score for Sample Student Response #9: Rubric Score 3

Annotation: This response demonstrates a complete understanding and analysis of the problem. The representation is correct with each house and garage correctly oriented. The student gives a full description of the first transformation. "I made a reflection of the house and the garage across the dividing line of lots" correctly identifies reflection and provides the line of reflection. For the description of the second transformation, the student correctly states "translated the house to the right" as well as "rotated the house 90° to the left." While the direction "to the left" should be appropriately described as counterclockwise, the error in terminology is considered minor. The third transformation is described as "a reflection across the dividing line of lot C and lot D," correctly identifying reflection and providing the line of reflection. Full descriptions of all transformations demonstrate application of a reasonable strategy to solve the problem.

Score for Sample Student Response #10: Rubric Score 2

Annotation: This response demonstrates a conceptual understanding and analysis of the problem. The representation is correct with the houses and garages correctly oriented. The student correctly identifies the transformations from lot A to lot B and lot C to lot D as "flips" (an acceptable term identifying reflection). However, the response lacks a full description because no line of reflection is given. The transformation from lot B to lot C is correctly identified as a rotation, but the student fails to provide the degree of rotation. Compare to Anchor Paper #3.

Score for Sample Student Response #11: Rubric Score 1

Annotation: This response demonstrates minimal understanding and analysis of the problem. The representation is correct; the houses and garages are drawn with the correct orientations. However, the student tries to describe how the drawing was made rather than the transformations required. Compare to Anchor Paper #1.

Score for Sample Student Response #12: Rubric Score 2

Annotation: This response demonstrates a conceptual understanding and analysis of the problem. The representation is correct; the houses and garages are drawn with the correct orientations. The student identifies the transformations from A to B and C to D as reflections ("flipped or reflected"), but fails to provide the line of reflection. The student correctly describes the transformation from B to C as a 90° rotation. However, reflection is only identified and lacks a complete description. Compare to Anchor Paper #4.
