Have students explore what it would mean to be a two-dimensional being
instead of a three-dimensional being. Ask a volunteer to come up to the

The most common mistake that people make is with the placement of
the flatlander's eyes. A person's first attempt at drawing a flatlander
usually has the eyes on the inside of the head:
If this happens, ask the students, "How will the flatlander see another
Also, people usually draw the mouth on the inside of the head, too. Then
how will the flatlander eat? A reasonable second attempt at a flatlander
head could look something like this:
Either continue discussion as a class, or let students explore possibilities in small groups using the questions on the activity sheet provided.
