Work Backwards — Reverse Engineering

🔎Case Brief #3

📖 You're reading a story and the character needs to use solving by starting at the end.

🎯 Your mission

Find the pattern.

⚡ The twist

The obvious answer is a trap. Look again.

What You'll Learn

🧠 Start with the answer you WANT, then figure out the steps to get there. Want to be ready for school by 8am? Work backwards: leave at 7:50, eat at 7:30, get dressed at 7:15, wake up at 7:00. 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!
