Tonal Shading – Polygon Shapes Worksheets

This printable art resource helps students practice tonal shading using a series of geometric polygon forms. Each worksheet presents a 3D polygon rendered with light-to-dark tonal values alongside a line drawing version for students to shade. A value scale is also included on each page for tone reference and blending practice.
What’s Included:
Multiple worksheets (10 PDF) featuring different polygon forms (cube, sphere-like polyhedrons, complex star forms, etc.)
Each page includes:
A fully shaded reference example
A blank polygon outline for students to shade
