What's the Rule? — Guess My Sorting Rule

🔎Case Brief #5

👫 You and your friend disagree about something.

🎯 Your mission

Solve the puzzle.

⚡ The twist

Only one answer can be logically true. The others feel right but aren't.

What You'll Learn

🧠 I've sorted things into two groups using a secret rule. Can you figure out what my rule is? This is called inductive reasoning — going from examples to discover the hidden rule. Here's how to do it: 1. Look carefully at the problem. What do you see? 2. Think about what you already know. Does this remind you of something? 3. Try an answer! It's totally okay to be wrong — that's how we learn. 4. Check: did it work? If not, try something else! You're building your thinking muscles. The more you practice, the stronger they get!
