ab: Summary: This article discusses an open-ended problem involving
quadrilaterals that is continually used each semester. The task has
been posed to undergraduate and graduate students in methods and
problem solving classes. The task involves drawing all possible four
sided figures with corners at the dots. A four by four array of dots is
included in the instructions and students are asked to develop a system
for knowing when they have identified all the quadrilaterals.
