Values to create a 3D looking face

In third grade children have been studying values. Values are variations of dark and light on a 2D art and can be used to create a 3D look. they began the unit by looking at a simple mug and finding and drawing it's values, as well as creating a value scale using crosshatch. For this particular lesson children had to touch the various 'mountains' on their face, choose a light source and figure out which side of each face 'mountain' would be dark, light and medium values.

We also talked about the idea of contrast and how contrast is often used in art to make the lights appear lighter and the darks appear darker. The artist below created a very deep contrast.
