Criteria and Performance Level Rationales
Problem Solving
Apprentice
The student's strategy of creating a table of three teams of students and calculating the total seconds per team to determine if they are equally matched works to solve the first part of the task. The student's tables on her/his "My Answer Page," correctly represent three equally matched teams. The student does not address the second part of the task.
Reasoning Proof
Apprentice
The student demonstrates understanding that Mr. Fair requires three possible teams of four students that are as equally matched as possible. The student does not show correct reasoning for the second part of the task.
Communication
Practitioner
The student correctly uses the mathematical term seconds from the task. The student also correctly uses the terms charts, total. The student correctly uses the notation 10.9, 9.9, 12.2, 8.9, 11.0, 11.9, 8.7, 10.3, 11.1, 10.5, 9.1, 11.4 from the task. The student also correctly uses the notation 41.9, 42.1.
Connections
Practitioner
The student makes the mathematically relevant observation, "Harry is the slowest crab walker becuse he only goes 12.2 seconds."
Representation
Practitioner
The student's three tables are appropriate to the task and accurate. Each team is labeled, the columns are correctly labeled and all entered data is correct.
