How to get better at pattern folding on the DAT
Updated October 29, 2026
Pattern Folding, officially called 3D Form Development, shows a flat pattern and four 3D figures. You pick the figure the pattern folds into.
You don't need to mentally fold the whole pattern. A few quick checks rule out wrong figures much faster: which faces are opposite, which faces meet at a corner, and which way the markings point.

The method, step by step
- 1
Remember you're seeing the outside
The pattern shows what will be on the outside of the folded figure. Exactly one of the four figures can be made from it.
- 2
Find the distinctive faces
Pick out faces with a unique shading, marking, shape or size. These are your anchors.
- 3
Find the opposite faces
On a cube pattern, two faces with exactly one face between them in a straight line end up opposite. Opposite faces can never be seen at the same time, so any figure that shows both is wrong.
- 4
Check a corner
Pick a corner of a remaining figure where three faces meet. Find the same three faces around one corner of the pattern, and check they appear in the same clockwise order. Mirror-image order means the figure is wrong.
- 5
Check the direction of markings
An arrow, a line or a half-shaded face has to point the right way relative to the faces next to it. Distractors often turn a marking by 90 degrees.

Pattern Folding tips and tricks
Start with elimination
Opposite-face checks are the fastest. They often rule out two options in a few seconds.
Shared edges stay shared
Two faces joined by an edge in the pattern are joined by that edge in the figure. Follow a marking that touches an edge to see which neighbour it must point toward.
Match sizes and counts for other shapes
The real test also uses prisms, pyramids and irregular shapes. Count the faces of each type and check their sizes: edges that join must be the same length.
Fold one face at a time
If you need to fold, pick one face as the base and fold its neighbours up around it, one at a time, rather than folding everything at once.
Common mistakes and how to fix them
A two-week plan to improve
Days 1 to 3: opposite faces
Do 15 pattern folding practice questions a day. Before choosing, name the opposite pairs. PAT Grind's explanations highlight them for you.
Days 4 to 7: corners and markings
Keep going in adaptive mode as the markings get subtler. On every miss, decide whether it was an opposite-face, corner or direction error.
Days 8 to 14: speed
Do sprint sessions at 40 seconds per question.
Measure it
Take a check-up before and after to see your pattern folding score change.
Pacing on test day
Budget about 11 minutes. Pattern folding comes last, so protect time for it by staying quick on angle ranking and hole punching.
Questions
Is the pattern the inside or the outside of the figure?
The outside. The DAT tells you the pattern shows what is seen on the outside of the folded figure.
What shapes appear in DAT pattern folding?
Cubes are common, and the real test also includes prisms, pyramids and irregular shapes. PAT Grind's practice uses cube patterns, but the same checks apply to every shape.
What's the fastest pattern folding trick?
Find the opposite faces first. Two faces that end up opposite can never be seen together, which rules out wrong figures in seconds.
