Build or Design a Doll House
"When you get to things like area and perimeter, build or design a real or hypothetical doll house or house. Go to your home improvement store and determine a materials list. Figure how much you need of what and how much it will cost. Need 58 square yards of carpet? Convert that to price per square foot (trickier than you might think). Wallpaper? How many rolls? Now, you're covering art, architecture, engineering, and so on and so forth." - FlattSpurAcademy
