Logical Thinking Basics
📋 What it is
Logic is reasoning where each step must follow from what came before — no leaps, no “because I said so”.
🗣️ Coach says
Logic isn’t about being clever — it’s about being careful. You start from what you know for sure, then take one honest step at a time. If a step doesn’t follow, you don’t take it.
🧠 Memory hook
One honest step at a time. If you can’t justify a step, don’t take it.

Why did the math student feel confident?
Because they had proof!
😲 Whoa!
The word “logic” comes from the Greek “logos” — meaning reason or account. People have studied it as a subject for over 2,000 years.
✅ Quick check: Someone says “All my friends like pizza, and Sam likes pizza, so Sam is my friend.” Is that a valid step?
Say your answer out loud first — then reveal.
No — liking pizza doesn’t make someone your friend; lots of non-friends like pizza too, so the conclusion doesn’t follow.
A valid step must follow necessarily; here the evidence fits many cases beyond the conclusion.

Say a claim out loud, then say the ONE fact it rests on. If you can’t name the fact, the claim isn’t proven yet.
