Problem Solving Rationale
<p>The student’s strategy of creating a representation and finding the number of units, leading to the number of feet in the perimeter, is correct. However, the student fails to multiply the number of total feet by $0.89 to successfully solve the task. Despite failing to make the calculation of converting from total perimeter to a cost, the student does arrive at a correct answer.</p>
Reasoning and Proof
apprentice
Reasoning Proof Rationale
<p>The student provides some correct reasoning for several of the steps. However, the argument is incomplete and inaccurate because the student fails to multiply the total perimeter by the $0.89 per foot, leading to an incorrect cost for the fencing. </p>
Communication Level
practitioner
Communication Rationale
<p>The student demonstrates a sense of purpose, clearly communicating this in the task statement at the beginning of the solution. The student’s overall approach is clear, organized and sequenced. Formal mathematical language, labels and symbolic notation are evident. </p>
Connections Level

<p>The student extends the task by finding the difference between the Meow Safe’s offer and their calculations. </p>
Representation
practitioner
Representation Rationale
<p>There is an accurate and appropriate mathematical representation created in step 1 of the task. This representation is constructed to help portray their calculations and strategy for arriving at their final answer. </p>
