Question P1 Seeing it move
Two triangles are joined as shown. What larger plane shape do they make?
Answer
square
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.
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.
