Teach the Cast
Some of DeduceQuest’s cast are still learning. When you teach them, YOU learn it best — catch what they get wrong, then quiz them.
Teach Rulewright
Teach the connections
Show how the reasoning ideas connect
Rulewright (guess-the-rule induction (form a hypothesis, then test it)) × Vary (controlling variables (change ONE thing at a time))
You guess "it turns green when the number is even". How do you test it WITHOUT fooling yourself?
Rulewright then says: “To test it fast, I'll change the number AND the color AND the size all at once.” — is that right?
Now they see it: a hypothesis is only as good as the controlled test behind it.
Tablo (logic-grid deduction (eliminate possibilities in a grid)) × Whittle (code-narrowing (never hunt — narrow TOWARD the answer))
What do logic-grid puzzles and code-narrowing have in common about HOW you find the answer?
Tablo then says: “In a logic grid you just guess the whole solution and see if it fits.” — is that right?
Now they see it: deduction isn't finding the answer — it's removing everything that isn't it.
Cogent (deductive vs inductive reasoning) × Contra (proof by contradiction (assume the opposite, watch it break))
Is "assume the opposite and show it's impossible" a deductive proof or an inductive guess?
Cogent then says: “Proof by contradiction is inductive — it's just noticing the opposite usually fails.” — is that right?
Now they see it: contradiction isn't a trick — it's deduction turned inside-out.
Capstone — crack the mystery
A locked-room mystery lands on your desk. Each part below needs ONE of the cast's ideas — bring in the right reasoner for each.
Sort the solid clues from the mere hunches.
Cross-check each witness's clue against the others.
Cross out suspect–room–time combos the clues rule out.
Form a theory of the culprit, then test it against a new clue.
Prove one suspect can't be guilty by showing their story forces an impossibility.
The whole cast, working together — because you taught each one and saw how they fit.
