This is in the ActiveInspire Flipchart format and is meant to demonstrate to the students how to shade each of the five forms (cube, cone, cylinder, sphere and pyramid) in a general way. It breaks down how the light effects everything and discusses the difference between shading a form and not shading a form.
Every other page has a blank form (i.e. a Sphere) waiting to be shaded, then the next page shows an example of an actual shaded form object (i.e. a basketball). At the end of the flipchart, I have all of the shaded forms that we did together so that if they missed any, they can catch up while I would walk around to help them individually.
I have my students work on a coinciding worksheet, which I also sell in my store, where they can follow along and shade on their own. Otherwise, you could just have them draw the form on a paper and practice shading.
