Inductive Reasoning
📋 What it is
Induction goes from specific observations to a general rule — a likely guess, not a certainty.
🗣️ Coach says
Induction builds up. You see many cases, then guess the rule behind them. It’s how science and everyday life work — but it’s only ever “probably”, because the next case could always surprise you.
🧠 Memory hook
INDuce = build UP from cases to a rule. Likely, never guaranteed.

What did the even number say to prove it's always even?
"Divide me by 2 — no remainder, no drama!"
😲 Whoa!
Induction is powerful but risky: for centuries Europeans induced “all swans are white” from thousands of white swans — until black swans were found in Australia.
✅ Quick check: Every prime you check past 2 is odd, so you conclude “all primes are odd.” Certain or likely?
Say your answer out loud first — then reveal.
Not even likely — it’s FALSE: 2 is prime and even. Induction can point you wrong if you miss a case.
A general rule induced from examples fails the moment one counterexample exists.

Watch which direction your family’s front door swings for a few days and induce a “rule”. Then ask: what single day could break it?
