    Study Notes

    Understanding Scale Maps

    • A scale map is a map that contains a scale, which is a ratio of two numbers that relates the map's measurement to the real-world measurement.

    How Scale Maps Work

    • A scale is typically represented as a ratio, such as 1:18,000, which means one unit on the map is equivalent to 18,000 units in real life.
    • The ratio can be used to convert between units, such as inches to feet.

    Converting Units

    • To convert units, divide the actual distance in inches by 12 to get the distance in feet.
    • Example: 18,000 inches ÷ 12 = 1,500 feet.

    Measuring with Everyday Objects

    • On a scale map, you can use everyday objects to measure distances, such as a pinkie finger or a pen.
    • The measurement must be consistent, and the scale ratio is used to convert the measurement to real-life distances.

    Creating a Scale Map

    • Step 1: Find a map of an area you want to use.
    • Step 2: Find the actual and measured distances of two points on your map.
    • Step 3: Divide the actual distance by the measured distance on the map to get the scale.
    • Step 4: Place the scale numbers on the map.

    Example of Creating a Scale Map

    • Find a map and measure the distance between two points (e.g., 2 inches).
    • Find the actual distance between the two points (e.g., 800 feet).
    • Convert the actual distance to inches (e.g., 9,600 inches).
    • Divide the actual distance by the measured distance to get the scale (e.g., 1:4,800).
