graph that is missing labels but is otherwise correct, and Part (b) is correct. 2 3.MD.3 Student attempts to complete the table but finds the incorrect number of marigolds in Part (a). Student is unable to correctly complete the picture graph in Part (b). Student correctly calculates the number of marigolds and attempts to scale, create, and label a picture graph in Part (b). Student correctly calculates 18 marigolds in Part (a) and correctly scales and labels the picture graph in Part (b), but incorrectly represents the number of flowers for one or more types in Part (b). Student correctly: Calculates 18 marigolds. Determines an appropriate scale and graphic representation; creates an accurate, labeled picture graph based on the data in the table. 3 3.MD.4 Student is unable to answer any question correctly. Student correctly answers either Part (a) or Part (b). Student correctly answers Part (a) and correctly identifies , , and in Part (b), but does not list the measurements in order. Student: Finds 18 sunflowers in Fred’s backyard and provides sound reasoning to support the answer. Lists , , and in order. 4 3.MD.4 Student attempts, but is unable to complete, either question correctly. Student draws the line plot correctly but may not explain her choice of scale. Student may make a minor error calculating Part (b). Student answers Part (a) correctly but makes a minor error calculating Part (b). Student: Creates an appropriate scale, draws a line plot to accurately display the data, and provides sound reasoning for the choice of scale. Finds 1 more shoot that measured inches than and inches combined.
