Glyphs are pictorial symbols that convey information without words. Common examples of glyphs include wheelchair symbols to indicate accessibility and male/female bathroom signs. Glyphs can be used creatively in activities with friends, where each person designs their own unique glyph using shapes and designs to represent different attributes about themselves. Comparing and analyzing each other's glyphs can provide an entertaining way for students to learn without speaking. The document provides instructions for students to each create their own star glyph by drawing different facial features and other shapes to secretly code personal preferences about gender, favorite foods, and feelings about school versus vacation.
