Abstract
Teachers in third through eighth grade teach area and perimeter simultaneously to their students every year
and expect the students to know the difference. Recognizing the concern that teachers have for the lack
of knowledge for area and perimeter, as well as their units, we share a lesson that allows the students to
connect the terminology and mathematics to the real world. Specifically, we use an enactive, iconic, and
symbolic lesson to find the cheapest fence for our garden.
