Logic Grid Puzzle Challenge

๐Ÿ”ŽCase Brief #11

Two experts disagree about an issue related to grid-based deduction.

๐ŸŽฏ Your mission

Crack the code.

โšก The twist

You can only use the clues you are given โ€” no guessing.

What You'll Learn

In a logic grid puzzle, you use clues to figure out which items match together. Cross off impossibilities until only the correct answer remains. Why does this matter? Grid-based deduction is a skill that will help you in school, in friendships, and in solving real-world problems. People who master this skill make better decisions and understand the world more clearly. Here's the process: Step 1 โ€” Define the challenge. What exactly are you trying to figure out? Being specific about the question is half the battle. Step 2 โ€” Gather information. What facts do you have? What might be missing? Not all information is equally useful โ€” focus on what's relevant. Step 3 โ€” Consider multiple options. Don't stop at your first idea. Challenge yourself to think of at least three alternatives. Often the best answer is one you didn't think of immediately. Step 4 โ€” Evaluate your options. What are the pros and cons of each? What evidence supports each one? Which option has the strongest reasoning behind it? Step 5 โ€” Make your choice and explain your reasoning. "I think ___ because ___" is the formula. Being able to explain your thinking is just as important as getting the right answer. Step 6 โ€” Reflect. Was your approach effective? What would you do differently next time? This reflection step is how good thinkers become great thinkers.
