Logic Problems

Logic problems give you clues and ask you to deduce the answer using careful reasoning. You may need to use a table, process of elimination, or step-by-step thinking.

Your goals

✓You can use reasoning to solve multi-step logic challenges.
✓You can use deduce, elimination correctly.
✓You can show which clue supports each conclusion.

Words to know

deduce:: Reach a conclusion from the information given.
elimination:: Remove choices that cannot be true.

Examples

1"If all cats are animals, and Whiskers is a cat, is Whiskers an animal?" → Yes!
2"Three friends have different favourite colours. Use the clues to match each friend to their colour."

Check these

• Do not use information that the problem never gives.
• Keep every number, symbol, label, and unit in its correct place.
• Show enough working to check how you reached your answer.

Helpful habits

• Read the whole question before choosing what to do.
• Show one clear step at a time and check each step.
• If you are stuck, draw a model, try smaller numbers, or revisit the example.

Now try your own

Create your own logic problems example, solve it, and explain how you checked it.
