Activity 01
Demonstration: Additive and Subtractive Demo
Model additive coiling to raise forms and subtractive carving for details on a sample tile. Pairs practice on small slabs, testing textures with handheld lights. Groups share one success and challenge.
Analyze how light and shadow interact with textured surfaces.
Facilitation TipDuring the Additive and Subtractive Demo, pass around a sample tile and ask students to trace the raised and carved areas with their fingers to feel the differences.
What to look forStudents display their finished clay tiles. In small groups, they use a checklist to assess each other's work, focusing on: Is the personal story clear? Are both additive and subtractive techniques visible? How effectively does light and shadow enhance the relief? Students provide one specific suggestion for improvement.
