Understanding Paper Folding in 11-Plus Non-Verbal Reasoning

Paper folding is a crucial topic in the 11-plus Non-Verbal Reasoning section, where students are required to visualize how a piece of paper will appear after being folded and having holes punched through it. This skill is essential for developing spatial awareness and visual problem-solving abilities.

The Process of Paper Folding

When approaching paper folding questions, students must carefully track the folds and how they affect the positioning of holes. Each fold can multiply the number of holes, and understanding the symmetry created by these folds is key to predicting the final appearance of the paper.

Key Concepts

Visualizing Folds: Students must practice visualizing how the paper will fold. For instance, if a paper is folded in half, the left side will overlap the right side.
Punching Holes: When holes are punched through the folded paper, they will appear in multiple locations once the paper is unfolded.
Symmetry: Understanding how folds create symmetrical patterns is crucial. For example, if a hole is punched on one side of a fold, it will appear on the opposite side when the paper is unfolded.

Example Problem

Problem:

A rectangular piece of paper is folded in half lengthwise. A hole is punched through the top layer, and then the paper is unfolded. Where will the hole appear?

Solution:

When the paper is folded in half, the left side overlaps the right side.
Punching a hole through the top layer means that the hole will appear on both the top and bottom layers once unfolded.
Thus, the final result will show two holes in the same position on the unfolded paper.

Practice Makes Perfect

To excel in paper folding questions, students should practice regularly. They can use resources such as BBC Bitesize or specific 11-plus preparation books that include visual reasoning exercises. By honing their skills in visualizing folds and understanding symmetry, students will improve their performance in the Non-Verbal Reasoning section of the 11-plus exam.
