As preliminary exercises, students worked on value scale drawings in pencil. They also did blind contour and contour drawings of their hands, and learned about shading techniques such as hatching, cross-hatching, and blending.
After they had experimented with various shading techniques and were comfortable with the new art terminology, they produced small drawings in pencil, using several different animal skulls as subject matter. The skulls were placed in the center of each table, and students rotated around the table to draw the skulls from different positions.
After they had drawn several small views of the skulls, they then completed one larger pencil drawing and at least one drawing in charcoal--an art material that was used in prehistoric times!
