📋 What it is

The reasoning tools connect: a conjecture from a pattern gets settled by a proof or killed by a counterexample.

🗣️ Coach says

None of these tools live alone. You spot a pattern (induction), guess a rule (conjecture), then either prove it (deduction) or break it (counterexample). Real thinking flows between them.

🧠 Memory hook

Spot → guess → prove-or-disprove. The tools hand off to each other like a relay.

😂 Giggle

Why was the axiom so confident?
Because everyone just accepted it as true — no proof needed!

😲 Whoa!

Most real discoveries loop through all four: notice a pattern, conjecture a rule, attempt a proof, and let a counterexample redirect you when the proof stalls.

✅ Quick check: You conjecture a rule from 6 examples, then find one case where it fails. Which two tools did you just use?

Say your answer out loud first — then reveal.

🧪 Try it! (2 minutes)

Take any pattern you noticed this week, conjecture the rule, then actively hunt for a counterexample before you trust it.
