Non-verbal reasoning: paper folding
Paper folding questions show a folded sheet with holes punched through it, then ask what the sheet looks like unfolded. Each hole is mirrored across each fold line.
What is tested
- One and two fold problems
- Where holes appear when unfolded
- Reversing folds in order
Worked example
A square is folded in half and one hole is punched near the fold. When unfolded, how many holes are there?
- The hole goes through both layers.
- Unfolding mirrors it across the fold.
- So there are 2 holes.
Answer: 2 holes
Exam-day checklist
- Unfold in reverse order.
- Mirror each hole across the fold line.
- Number of holes doubles with each fold.
- Check that holes are the same distance from the fold.
Common mistakes
- Forgetting to mirror the hole.
- Unfolding in the wrong order.
- Miscounting holes.
Try it yourself
1. The paper is folded twice and one hole is punched through all layers. How many holes when unfolded?
Show answer
4
Each fold doubles the layers: 2 × 2 = 4.
2. The square is folded once and a hole is punched 1 cm from the fold. When unfolded, how far from the fold is the second hole?
Show answer
1 cm on the other side
Reflections keep the same distance from the fold.
