Students interview a partner acquiring information and draw a coded representation of the information. These glyph pictures can be used to convey information about classmates. The pictures can be displayed in class, and make a great "getting to know you" activity. From the information, students can make Venn diagrams showing similarities and differences.
A good introduction to coding, and a nice introduction to how humans have created glyphs (hieroglyphics) to represent data since ancient times.
