Draw a skyline with roofs of Dutch canal houses on the white sheet. Cut it. Choose a colour to stencil with. Rub chalk on the stencil. Use a tissue or your finger to rub the chalk off the stencil on the black sheet, to create the soft looking skyline.
Turn the stencil and take another colour to repeat this process. Students may also exchange the roof with your neighbour, to get different skylines.
Draw a moon with chalk pastel. Draw windows in the houses and colour them with a yellow and/or white pencil.
