Perimeter and area

A day before testing began, I had one day left to review any math concepts from the year, and what do I decide to do? Took each math class out on the field and had them line up shoulder to shoulder, the length of the side of the rectangular shaped field (the base), and then the other side of the field (the width).
Since I only had about 26 students per class that day, the children kept moving down the line, to form new parts of the line, to cover the entire base and width of the field.
At first I made them hold hands so they'd stay in straight lines, but then they got the hang of what we were doing and just followed each other making up the new parts of the sides.
Our results were that it would take 764 students standing shoulder to shoulder, to make the perimeter of the field at our school covered.
Next we found area by multiplying the base X the height, and found it would take 32,760 students standing shoulder to shoulder to fit on the inside, in the area of the field!
I hope the students remember the difference between area and perimeter now!
