This is a one-page PDF that gives a brief overview on value and shading in artwork. It features a completed 5-step gradated value scale, then asks the student to complete a blank value scale to match the tones.
I use this as a tool for students to practice using pressure to show value. When completed, students then use their scale as a reference for their drawing projects to ensure they've used at least five values in their work.
