Commentary:
This task would have been better if the instructions had ruled out help from another person with the task of peeling the potato. About one quarter of the year 4 students used that option, which accounts for slightly higher workability that they achieved. Otherwise, 20 to 30 percent more year 8 than year 4 students succeeded with the main elements of this task.
