A square of paper is folded, a hole is punched through it, and the child pictures the sheet opened flat again. It sounds simple until you meet one: the folds have to be undone in reverse, and every fold doubles the holes. These are the same puzzles that appear on the CogAT nonverbal battery and in olympiad logical reasoning papers.
No account needed. Fresh questions every time you press for five more.
Worth saying out loud the first few times. The order matters more than the speed.
One fold is two layers and two holes. Two folds are four layers and four holes. Doing this before looking at the options rules out most of them immediately.
A line down the middle mirrors left to right. A line across mirrors top to bottom. Two lines do both.
Undo the last fold first. Place the new hole the same distance from the line as the original, on the other side.
This is where most wrong answers live: the right number of holes, in the right quarters, but bunched near the middle instead of out by the corners.

These are not guesses. They are what the wrong options in a real question are built from, which is why each one feels reasonable at the time.
The fix: The punch goes through every layer. Count layers before anything else.
The fix: A fold running down the paper mirrors sideways. A fold running across mirrors up and down. Read the dotted line before you move anything.
The fix: The new hole is exactly as far from the line as the punched one. Measure it against the picture rather than eyeballing the quarter.
The fix: Two layers give two holes, not three. If an option has more holes than the paper had layers, it is out.
A square of paper is folded one or more times, a hole is punched through the folded stack, and you work out where the holes are when the paper is opened flat. It tests spatial visualisation: holding a shape in mind and transforming it, rather than recalling anything.
As many as there were layers. One fold gives two layers and two holes, two folds give four layers and four holes, three folds give eight. Counting layers first eliminates most wrong answers before you think about position at all.
The CogAT nonverbal battery includes paper folding, CAT4 covers it in its spatial content, and it appears in SOF olympiad logical reasoning papers from around class 3. It is also a staple of the DAT perceptual ability test, though that is an adult dental admissions exam with much harder items.
Around seven or eight for single folds, where the reasoning is one mirror image. Two folds are noticeably harder because the mirroring compounds, and most children need the single-fold version to be automatic first.
With paper. Fold a sheet, punch it with a hole punch, and let the child predict before opening it. The prediction is the whole exercise; opening the paper marks it instantly, and the physical version builds the mental one faster than any worksheet.
Almost always because they mirrored across the wrong line, or kept the right side but the wrong distance. Those are two different errors with two different fixes: read the dotted line first, then match the distance to the fold rather than to the edge.
It is one kind. Spatial visualisation covers rotating, combining and reflecting shapes in general; paper folding is the reflection case, made concrete. Children often find it the friendliest entry point because they can check their answer with real paper.
The underlying spatial ability develops slowly, but performance on these items improves quickly with familiarity, because a large part of a first attempt is spent working out what is being asked. Removing that cost is what practice does here, and it is worth doing before a test rather than during it.
One skill at a time is how you fix a weakness. A full timed test is how you find out whether it is fixed.
