Lesson Objectives: Students will learn how to use value to create shading to indicate a light source.

Time Required: 1 hour

Artist: Wayne Thiebaud, Cake Window, French Pastries


Black Construction paper 8” wide and 22 “ long

Oil pastels

Cardboard cut in half to reveal the corrugated center (optional)

Elmer’s glue (optional)


Discuss value: the amount of light in a color. High values are high in light, resulting in a lighter color. Low values are low in light, resulting in a darker color. Discuss how a light source makes the side of the object closest to the light lighter, while the side further away is shadowed or darker.


  1. Pass out the black paper. Write name on back. Orient vertically.
  2. Choosing an oil pastel color/flavor of ice cream, draw an outline of one scoop of ice cream at the top of the page, leaving room for a cherry on top.
  3. With a red oil pastel, draw the cherry outline plus a stem.
  4. Continue on down the page drawing outlines of ice cream scoops with different colors to reflect different flavors of ice creams.
  5. Leave enough room at the bottom for a cone. The cone can be drawn in with brown oil pastel, or a triangular piece of cardboard could be cut out and glued down for the cone.
  6. Determine which side of the ice cream cone the light source is on. With an oil pastel color that matches the outline, color in the scoop so that one side is lighter and the other side is darker.
  7. The side closest to the light source can be made lighter by blending in a lighter shade of the same color or white. The side furthest from the light source can be made darker by pressing harder with the oil pastel or blending in a darker shade of the same color.
  8. The more you add oil pastel, the creamier it gets and the easier it is to blend.
  9. The lighter sides of the ice cream scoops should all be on the same side!
  10. Embellishments may added: chocolate chips, etc.
