Children get three pieces of grey drawing paper. They have to draw the same snowmen face or part of the face from different points of view: frontal, of the side, from above, from the bottom, upside down etc. The snowmen must be coloured with oil pastels. Of course the colours of all drawings have to be the same. Outline everything with black oil pastel. Glue the three snowmen close ups on a matching coloured cardboard.
