3rd grade value and form drawings

3rd graders studied the difference between two-dimensional and three-dimensional objects in art. Together we drew three forms-- a cube, a sphere and a cylinder. We then discussed how light affects and changes the way things look. We imagine the sun was shining in the top fit corner of our drawing and after completing a value scale in pencil, we shaded our forms. The last part was the background. Using only one marker, we created an abstract design that was 50/50 white/color of our choice.
