City of Salem Schools
Objectives
Prior to this activity, the students have demonstrated a knowledge of
•The definition of latitude and longitude
•The concept of hemisphere and how the globe is divided into four
hemispheres.
•The Student will draw a compass rose and determine orientation on a
map.
•The student will locate and label latitude and longitude coordinates on a
map of the world
•The student will state the relative location of regions on a map.
•The student will estimate the distance between two points on a map by
using a scale of miles.
•The student will compare maps to understand how the scale ratio
determines the amount of detail on a map.
Orientation
Location or
position relative to
the points on the
compass.
Cardinal Directions– North, South, East, West
Intermediate Directions- Northwest, Northeast,
Southeast, Southwest
Draw a compass rose and fill in the
cardinal and intermediate
directions.

Absolute Location
The global address of a point on the globe is an
absolute location.
The latitude and longitude coordinates define the
absolute location of a point on the globe.
The correct order for global addresses are
North and South followed by East and West
60°N, 120°W is a correctly written address.
Absolute location is the point were lines of
latitude and longitude intersect on a grid.
Longitude lines or Meridians run north to
south but are read east to west.
Latitude lines or Parallel lines run east to
west but are measured north to south.
Step 1. Highlight the Equator
Step 2. Highlight the Prime Meridian.

Step 3. Draw and X where the two lines intersect.
Step 4. Label the hemispheres

Step 5. Locate 20°N, 80° W
• Locate the Northwest hemisphere. Why
• Locate 20° N, draw a line along this line to the Prime Meridian .
• Locate 80° W, draw a line along this line to the Equator
• Where the two lines intersect is 20°N, 80° W

Scale
Ratio between a distance on a
map and the corresponding
distance on the earth

Representative Fraction
• a fraction or ratio between units on the
map and units on the earth’s surface
• format
– 1:1,000,000 OR 1/1,000,000

Graphic or Bar Scale
• a line subdivided like a ruler to show the lengths
of earth distance units on the map.
