  1. Understanding Scale

  2. SCALE:a comparison of distances on a map to distances on the earth • METHODS OF PORTRAYING SCALE ON A MAP: • Graphic Scale = scale bar • Verbal Scale = written statement • Fractional Scale = representative fraction

  3. What kind of scale? “One inch to 5 miles” Verbal scale

  4. What kind of scale? 1:316,800 or 1/316,800 Fractional Scale
