About this method

Seeing it move

Work out where the pieces land after a fold, cut or stack.

In this one. Small plane shapes can join without gaps to form a larger shape.

ABCDEFa straight strip of three: the two ends land opposite

How to spot it

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.

Common mistake

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.
