Overview

GOAL: To use the battlefield as a vehicle for the study of math.

Objective(s)

The student will be able to determine the area and perimeter of a given rectangle or square with given dimensions.
The student will be able to solve word problems involving area and perimeter.
The student will distinguish between the concepts of perimeter and area (that perimeter is the distance around and area is the measure of a covering).
Be sure students can convert feet to inches and inches to feet. Students should know that there are 12 inches in one foot.
Students should be advised that all sides of a square are of equal size.

Background

After touring the sites at the Cowpens National Battlefield, students will be given the following worksheet. It contains dimensions of different items within the park. All the items are either rectangles or squares. Give students the formulas for finding area and perimeter of rectangles and squares.

To find the area of a square or a rectangle, multiply the length times the width. (A = L x W)

To find the perimeter of a square or a rectangle, calculate the sum of all the sides. (P = S+S+S+S)

NOTE

Make sure students understand that in calculating area, the results are in squared units.

Before computing, have the students make sure that the units are the same, i.e., inches times inches, feet times feet, etc.
