A Backyard Map With a Scale
Mapmakers have a problem. The places they draw are far bigger than any sheet of paper. A backyard may be 60 feet wide, yet a map of it must fit on a page. The solution is a scale.
A scale tells you how a distance on the map matches a distance in real life. Suppose a backyard map says that 1 inch equals 5 feet. That means every inch you measure on the paper stands for 5 feet on the grass.
Now let us use it. On the map, the oak tree is 6 inches from the garden shed. How far apart are they in the yard? Each inch is worth 5 feet, so you multiply. Six times 5 is 30. The tree and the shed are 30 feet apart.
You can also work backward. If you want to know how a 10-foot sandbox should look on the map, divide 10 by 5. The answer is 2, so you draw it 2 inches long.
Scales are not always the same. A map of a whole city might use 1 inch for a mile or more. A small scale lets you see a huge place. A large scale shows a small place with more detail. When you read any map, look for the scale first. It turns a flat drawing into a guide you can measure.
