Problem Solving Rationale
<p>The student's strategy of using a number line to indicate the ladybugs and crickets Ben and Jill have in their jars, finding the total number of insects per jar, and comparing the totals to see if Dad is correct, works to solve the task. The student's answer, "A-no," is correct.</p>
