The student's strategy of using a tally chart to show the five completed pictures and the five pictures needed to be drawn works to solve the task. The student's answer, "5 more," is correct.
Reasoning & Proof
Practitioner
The student shows correct reasoning of the underlying concepts of the task. The student tallies the completed pictures, the pictures needed to be completed, and compares the two totals to determine that five pictures need to be completed.
Communication
Practitioner
The student correctly uses the mathematical terms "tallys," (tally chart), more, amount.
Connections
Practitioner
The student makes the mathematically relevant observation, "I see Ryan has the same amount of pictures finished and to draw." The student also describes how a tally works, "You go 1, 2, 3, 4 then the sideways tally for 5."

Scoring Rationale
Problem Solving
Practitioner
The student's strategy of using a number line to show the five completed pictures and the five pictures that still need to be drawn works to solve the task. The student's answer, "5 more," is correct.
Reasoning & Proof
Practitioner
The student shows correct reasoning of the underlying concepts of the task. The student jumps the five completed pictures. The student understands that they need to count on from five to find that there are five more pictures to draw.
Communication
Practitioner
The student correctly uses the mathematical terms number line, more, diagram.
Connections
Practitioner
The student uses a new strategy of a diagram to show the five finished drawings and states, "He has to do those 5 more for 6, 7, 8, 9, 10 pictures. Then he will be all done." The student does not earn the Expert level because they did not compare the two strategies to confirm that the answer is correct.
Representation
Practitioner
The student's number line is appropriate to the task. The numbers are labeled and the "jumps" are accurate. The student's diagram is appropriate to the task. The scribing provides the necessary labels for the completed pictures.
