Dibujo a lápiz de figuras con líneas y sombreado

In this class the students will learn how to create a simple volume to add a two dimensional art on a piece of paper.
I will teach them how to draw shapes and have the feeling of the volume of real images. All on the single piece of paper. 
My style is pretty easy, each step includes a live demonstration with an image. In general it will include drawing lines and shades to experience the negative space. The level of difficulty is featured for 8-10 years old but some examples are good for older kids.
 Simple clear  object are involved to add an artistic look.
There will not be necessary any drawing experience for the class, any levels are accepted. Any creative attempts and desire will be an advantage.
Week ONE - drawing with teachers' step-by-step instructions
Week TWO - creating a new composition with own theme and teachers help.
