Problem Solving Rationale
<p>The student's strategy of diagramming the ladybugs and crickets Ben and Jill have in their jars works to solve part of the task. The student's answer, "NO," is not correct because it is based on comparing nine ladybugs to eight ladybugs and not the total number of insects in each jar.</p>
Reasoning and Proof
