To Build a Dog Run: The Relationship between Perimeter and Area
Wiest, Lynda
Australian Primary Mathematics Classroom, v10 n2 p21-25 2005
Perimeter and area are important real-world concepts in their own right, and their relationship certainly is no less important. This relationship can be intuitively challenging for both children and adults. In this article, the author explores the relationship between perimeter and area with students from grades 4 to 6. The study of perimeter-area relationships using various types of shapes not only encourages important mathematical explorations, but it also lends itself well to authentic applications beyond the classroom. In the activity described here, students attempt to make sense of the perimeter-area concept through explorations with colour tiles and subsequent decisions about what dimensions they would give a rectangular dog run with a specified amount of fencing. Preparation for this activity includes helping students achieve conceptual understanding of perimeter and area, including how to find each in units or square units, and being able to provide real-world examples of their use (e.g., framing a picture or painting a wall).
