The Straw Manikin by Goya
The Philosopher's Lamp by Magritte
The first game the 6th grade did in class this week was "Finish the Picture". Each student got a paper with a section from a famous piece of art from history. They were asked to finish the scene not knowing what it came from. After ten minutes of drawing I showed them the original art.
The next game was "Synchronized Drawing". In pairs the students would fold the paper in half then one would lead the drawing while the other would follow. You get all sorts of interesting drawings with this one.
