Work out where the pieces land after a fold, cut or stack.
In this one. A small cube is painted on exactly the block faces it touches — so "0 faces" means strip a 1-cm skin off all six sides and count what is left, and "2 faces" means it lies on an edge but is not a corner.
Words like 'folded', 'cut along the dotted line' or 'stacked' appear beside a shape, and the question asks for a length or angle that only makes sense once the pieces are in their new positions.
Children try to calculate the answer before working out where the pieces actually end up, skipping the visualisation step that the whole question depends on.
