Quick Draw: Poses

I found this idea on the Campaign for Drawing site. Neat idea that we can also do, maybe in one of the Art Workshops?

Poses
20-second poses, pupils using black paper and chalk. After each drawing, children moved three places and drew again on someone else’s drawing in a different coloured chalk. Gallery time prompted discussion about the experience and the drawings. Pupils returned to their original drawing and had to change it into something else. What could they see coming from the drawing? Drawings were held aloft so that pupils could share.
