🔎Case Brief #12

🎯 Your mission

Unlock the thinking move.

⚡ The twist

You can only use the clues you are given — no guessing.

What You'll Learn

🧠 An assumption is something you believe is true WITHOUT checking. We all make assumptions every day. 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!
