This 2 page worksheet set is a good introduction for students learning about tint and shade, light and dark, and how shadows are seen in a 2D plane. This worksheet set is a good reinforcement for students who have missed relevant classes or require further reinforcement.
This page includes a shaded value scale and a blank value scale for practice, as well as a more complicated shape for the first applications of shading.
This page is an intermediate level worksheet where students take the knowledge they learned about value, and apply it to the idea of light and shadow. Students will shade the four small images with their previous value scale, applying varying levels of darkness where they see fit.
