This activity teaches perimeter and area in the real world. Students are asked to work in pairs to find the perimeter and area of items around the classroom or around the school. They must first think about the best unit of measurement for each object they choose. Then, they must make an estimate of the perimeter and area of the objects. This allows for great student discourse around making educated estimates and about the difference between perimeter and area. Finally, students will take rulers, yard sticks, or measuring tape, and actually measure objects in order to find the perimeter and area. This allows them to apply the concepts of perimeter and area to real world objects. Once a student has found the actual perimeter and area of an object (as opposed to on a worksheet) they will be able to easily recall how to find perimeter and area of any object. I suggest teachers begin with square or rectangular objects, and move to objects with less than or more than four sides once students have a grasp of the concept.
