Teacher introduces the topic of value and value scales. Teacher does a demo on how to create a range of values. Students practice creating value scales in their sketchbook. Students choose a base object (keep it simple and large) to sketch in their sketchbook. The students divide up the page and practice creating a full range of value in each shape created by the crossing lines. Once they understand, the students create it on the final. Optional to blend their values with a tortillion stump or cross hatching. Focus on the change of value every time they cross a line.
