Perspective drawing is all about creating an illusion of space in an artwork - there are lots of different ways to show 3-D perspective. 5th graders drew buildings using two vanishing points on the horizon. They personalized their drawings with details of their own after learning the steps.
Fourth graders learned to draw a landscape using one vanishing point on a horizon line.
Third graders experimented with a horizon line, a road connecting to a vanishing point, high and low placement, and size changes - all help to create near and far space.
