The Problem Solving and Communication Activity Series Look at Cases
Look at Cases
Cases is an unfamiliar strategy for many students, but it's an important way to analyze problems. Looking at cases can help break a tough problem into manageable parts, or help confirm if a solution is general enough to work in every case. Because it's an unfamiliar strategy, we've offered a list of cases that mathematical objects often come in, and offered activities to help students explore those different cases.
