Venn Diagram Thinking — Compare Anything

🔎Case Brief #8

📖 You're reading a story and the character needs to use compare and contrast tool.

🎯 Your mission

Learn it, then use it.

⚡ The twist

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

What You'll Learn

🧠 A Venn diagram uses two overlapping circles to compare things. The overlap shows what's THE SAME. 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!
