Creating depth with shading in ink

This is a project I had to do myself when I was taking art-class in 8th grade.  It's till fun rummaging through the old projects my mother couldn't throw away.  I'm grateful she didn't, there are some hidden gems in the pile!

With this project shading with ink is practiced.  The children have to learn that shading with ink and coloring with ink is totally different than shading with paint.  They tend to fill the whole space and as you see the darkest part of this drawn is still showing some background.

On an A5 sized piece of drawing paper the children should draw at least 3 see through walls with windows and/or doors.  They should fill the walls with shading in ink.  Discuss with them where the shading should go.
In the front there is a figure in profile.  Tell them how a profile of a figure should look.

Instead of ink they can use waterproof markers too, it depends on what your goal is (the shading or the technique of ink).

When the shading is done and the ink is dry they can color the walls with watercolor or colored ink.  The darkest shade is at the front, the more they go to the back, the lighter the shade will get.
