Reverse the action—do not guess the finished picture

Unfold in reverse: undo the last fold first. Reflect every mark across that crease.

Preserve distance: a reflected hole stays the same perpendicular distance from the fold.

Track cube relationships: opposite faces never touch; adjacent faces share an edge.

Fix a reference: rotate the whole object mentally while keeping one face or corner anchored.

DO IT FAST

Use ANCHOR → REVERSE → MIRROR → CHECK

1. ANCHOR: mark the fold, fixed face, or unchanged corner.
2. REVERSE: undo transformations in the opposite order.
3. MIRROR: copy position and orientation accurately across each crease.
4. CHECK: verify number, symmetry, adjacency, and orientation.

ACET trap: a plausible option often has the correct number of holes or faces but one reflected position is wrong.

GUIDED TRY

One fold creates a mirror pair

1. The right half is folded onto the left.
2. A hole is punched near the folded sheet’s upper-left area.
3. Undo the fold across the vertical crease.
4. The second hole appears at the same height and equal distance on the right.

Rule: reflect the punch across the crease; do not rotate it or move it along the crease.

QUICK ANSWERS

Spatial Reasoning FAQ

Do folds double the number of holes?

Usually, but a punch on a crease reflects onto itself. Count only distinct final positions.

How do I solve two folds?

Undo the second fold first, reflect every hole, then undo the first fold and reflect the expanded pattern again.

How do I identify opposite cube faces?

On a valid net, fold around one chosen face. Faces landing across from one another are opposite and can never appear adjacent in a cube view.

What makes a spatial distractor tempting?

It preserves one feature—such as count—while reversing the wrong direction, changing adjacency, or moving a mark the wrong distance.

Separate paper-folding errors from cube and rotation errors; they require different correction strategies.
