The document discusses visual puns, which are images that depict objects or arrangements of objects in a way that suggests a play on words based on the names of the objects. An example given is a notebook, which is a visual pun because it depicts an actual notebook. The document then instructs students to brainstorm ideas for their own visual puns by sketching concepts based on suggested pun ideas or their own, then developing their favorite into a digital image. Students are provided a list of pun ideas to consider for their sketches.
