Four figures share a feature. Spot the one that doesn't.
Practise 10 odd one out questions
How these questions work
Five figures are shown and four of them have something in common. Your child picks the one that doesn't belong. It's the mirror image of a similarities question: find the rule, then find the figure that breaks it.
Worked example
Which figure is the odd one out?
Show answer
Answer: B Four figures use shapes with 4 straight sides; the odd one out has 3.
Tips
- Don't pick the figure that just looks most different. Find the rule that four of them follow first.
- Cover one figure at a time with a finger and ask: do the other four share something this one doesn't?
- Counting is the most common hidden rule: sides, items, dots, lines.
The usual trap: A figure with an eye-catching difference that isn't the rule, like a different shape when the rule is about shading.
