When I was growing up, I spent hours on the tire swing in our backyard - swingin', thinkin' and watchin' the world around me.
Using a variety of pictures for reference, my young students drew a tree, a horizon line (where the sky meets the ground), a tire swing and clouds. How they arranged their composition was up to them.
Then, we went in with our No. 2 pencil! Depending on which part of the drawing we were working on, we used our pencil in different ways to create light, medium and dark values (shading) and a variety of textures (how something would feel if we could touch it).
It was actually snowing and blowing outside while we worked on these drawings. So - using masonite boards to support our paper, we gathered around the fireplace to create! :)
