One-Hole Punch Puzzles are hands-on spatial reasoning tasks where you must fold a square of paper so that a creates a complex pattern of multiple holes upon unfolding . Popularized by Mark Chubb at Thinking Mathematically , these puzzles transform traditional multiple-choice aptitude questions into active, inquiry-based learning. How the Puzzles Work
: Replicate a specific grid or pattern (e.g., a "2x2" or "3x3" arrangement) with only one punch.
: You cannot punch more than once; the complexity comes entirely from how the paper is folded.
The objective is simple but challenging: take a square of paper and use as many folds as needed so that one punch through all layers matches a provided template.
: These puzzles rely heavily on symmetry . Every fold creates an axis of symmetry, and the final pattern is a result of reflecting the single punch mark across these axes. One-Hole Punch Puzzle Templates - Thinking Mathematically
