"Which has more wheels: two bicycles or one car?" Many people answer "the car!" before they've finished thinking. The answer is that they're the same: four wheels each.
Trick questions catch us because our brains like to rush. We hear a familiar pattern and jump to an answer. Learning to slow down, listen to every word and check what's really being asked is a valuable thinking habit, and trick questions are a fun way to build it.
Why trick questions are good practice
- Careful listening. The trick is almost always hidden in a small word. Children learn that every word matters.
- Stopping before answering. "Wait, what exactly is the question?" is a habit that helps in every subject.
- Noticing assumptions. Many tricks work because we assume something that wasn't said.
- Laughing at mistakes. Getting caught by a trick question is funny, not shameful, which helps children relax about being wrong.
- Maths word problems. At school, many mistakes in word problems come from not reading the question carefully. Trick questions train exactly that.
Five kinds of trick, with examples
These are our own examples. Read them aloud slowly the first time, and quickly the second time to see how much harder it gets.
| Kind of trick | Example | Answer |
|---|---|---|
| The question asks something else | "Four ducks are on a pond. Two more land and one flies away. How many legs does a duck have?" | Two |
| Missing information | "A child has three red balloons and two yellow ones. How many green balloons does the child have?" | None |
| Same, not more | "Which has more wheels: two bicycles or one car?" | They're the same: four each |
| Nothing changed | "You put a red ball into a blue box. What colour is the ball?" | Still red |
| Count everything | "A cat is sitting on a chair. How many legs are there?" | Eight: four for the cat and four for the chair |
After each one, talk about the trick: "What made it tricky? Which word did you miss?"
How to play kindly
- Laugh together, not at each other. Adults get caught too. Say so.
- Say it again slowly. If your child gets it wrong, repeat the question slowly and let them try again.
- Explain the trick. The point isn't to win; it's to notice how the question fooled us.
- Mix in normal questions. If every question is a trick, children start to distrust everything. Mixing them in keeps everyone listening.
Invent your own
Making up a trick question is even harder than answering one, because you have to imagine how someone else will think. Help your child invent a few:
- Start with a simple fact ("a spider has eight legs").
- Add some distracting details before the question ("Three spiders are on a wall. One climbs down…").
- Ask about the simple fact at the end ("How many legs does a spider have?").
Children love trying their own trick questions on grandparents, siblings and friends.
The link with word problems
The same strategies that beat trick questions help with maths word problems:
- Find the question. Underline or point to what is actually being asked.
- Say it in your own words. "So they want to know…"
- Check the answer against the question. Does the answer match what was asked, or something else?
Ideas by age
- Ages 4–5: "nothing changed" and "count everything" tricks with real objects to look at.
- Ages 6–7: "the question asks something else" and "missing information", spoken aloud.
- Ages 8 and up: written trick questions, inventing their own, and applying the strategies to word problems.
In short
- Trick questions catch us because we answer before we've really listened.
- They train careful listening, careful reading and checking what's really being asked.
- Play kindly: laugh together, repeat slowly and explain the trick.
- Invent your own, and use the same strategies for maths word problems.
