How about setting up a light on various objects either alone or in a
group. Maybe if your students actually see the light source hitting the
object (sphere, cone, or whatever) they will understand the concept more
clearly.

There's an old saying,"When things go wrong, go back to the basics"
Do some lessons on basic drawing with cube, sphere, and cone.

1.Make a value chart with a slip of paper divided into 5 equal parts. Number
than 1 to 5 with 1 as pure white, 5 as darkest value, and 3 as a value
between 1 and 5. Then 2 as a value between 1 and 3, and 4 as a value between
3 and 5. Check by 'sighting' along the spaces by holding up to eyes and
looking along the paper horizontally, they should appear to blend.
2. Draw a cube. Specify a light source. (Sketch a light bulb in upper left
corner of paper) Top left face is a 1. Right face is a 4. Front face is a 3.
And left face a 2.
Value 5 is for shadow. Then go on the other basic forms
Well you know!
But back to basics is the way to go IMHO
