Masks are a wonderful way to express hidden parts of oneself, show the personalities of characters, and understand the human face.
Have students work with paper, colored pencil, scissors, or an media available. You may want to provide a template. It can also be helpful to draw masks from characters and ideas. Provide vocabulary words to illustrate an idea, like "storm" or "porcelain". You may want to provide clippings of story-book excerpts for individual characters. You can also have the students list the characteristics of story characters.
A nice way to begin is to draw up related textures and patterns. I'll be posting swatch-book photos of patterns and textures soon. Swatch books are a great class project to work on that students can reference their explorations. More on that soon.
