Problem Solving Rationale
<p>The student's strategy of diagramming the boats, kids, and fish, and providing an accurate key works to solve the task. The student states a correct answer, "36 fish."</p>
Reasoning and Proof
practitioner
Reasoning Proof Rationale
<p>The student demonstrates understanding of the mathematical concept of applying multiplication and patterns to find the total number of fish that can be caught while fishing. The student also applies multiplication and addition in determining the total cost of the 36 fish sold at 50 cents per fish.</p>
