Direction and Scale
© Boardworks Ltd 2001
Starter
• A compass rose is a design on a map that shows
directions. It shows north, south, east, west,
northeast, northwest, southeast, and southwest.
On the compass rose, only north is filled in.
• Fill in the rest of the directions on the compass
rose, using the standard abbreviations:
• N=North,
S=South,
• W=West,
NE=Northeast,
• NW=Northwest,
E=East,
SE=Southeast,
• SW=Southwest.

Directions
• When north is at the top of the
compass rose (as it often is),
south is at the bottom, east is on
the right, and west is on the left.
Northeast is between north and
east, northwest is between north
and west, southeast is between
south and east, and southwest is
between south and west.

Lesson Objectives
• To understand what the compass
rose is and how we use it.
• To know why we use scale on maps.
• To be able to use scale to measure
distances.

Scale
• What is a scale used for on a map?
• Are all maps at the same scale?

The scale on a map can be written in different ways:
A scale line
Use ‘ : ’which means represents
0
1km
1 : 25000
This means 1 cm/metre/kilometre on the map
represents 25000 cms/metres/kilometres on land

Using a scale
• "Take a look at this map! It
gives a statement of
equivalency: One cm = four
miles. The shortest distance
between the two towns is a
straight line (along Bo Ring
Way)! First, place a ruler
marked in centimetres (cm) on
the map and measure how
many cm separate the two
towns on the map! The two
towns are about 2.5 cm apart!
• Since each cm on the map
represents about 4 miles on the
ground, Louberg and Luluville
are about 2.5 cm times 4
miles per cm = 10 miles apart
on the ground!"

Bar Scale
Another form of scale is a
bar scale. All you have to do
is take a piece of paper, mark
off miles from the bar scale
onto the edge of the paper,
and then hold the edge of the
paper so that it lies along Bo
Ring Way from Louberg to
Luluville. If Louberg is at the
zero miles mark (red arrow),
then you can see that
Luluville is about 10 miles
away (other red arrow)
