Value Scales and Spheres!

Hi everyone!  This week I am teaching 5th grade how to do a value scale and a sphere shape with shadow.  We are using ebony pencils.  These kids have had an extreme lack of teaching in the shading world so I thought this would be a good start.  Their main objective is to create a value scale and then to draw a sphere with a horizon line, light source, and a shadow.  I'm hoping this lesson goes over well!  I created a demo video to show them how to do it and to free up my hands for when they need help!

This is actually my first lesson with ebony pencils so please, if you have any tips and tricks, comment below with your suggestions!  I love the feedback!
