This works well with young kids. Have them stand in front of the wall in a
pose, possibly using props (shooting a basket with a ball, painting with a
paintbrush, etc.). Cast their shadow on the wall using a bright light.
Have one or two other students use a pencil to trace the sillohuette. Have
students paint the drawings (solid primary colors work well for younger
students) and add background if you wish. You can create a whole scene
using any theme (playing sports works well). I had a student stand on a
box and we traced his sillohuette, leaving the box out. We then added a
jump rope in his hands as if he were in mid-jump. This can be a great
lead-in to simple figure drawing.
