3. For today’s session…
You will be recapping on what you learnt for atlas
(page 35)
You will be recapping on how to read scale on a map.
You will be learning some basic map skills
Eastings and northings
Four-figure grid references
Six-figure grid references
Finding directions on a map
4. Question 1
You are to revise what you learnt for
atlas on page 35 – 39 before you do it.
You may refer to the textbook while
you’re doing the question.
6. What is scale? (page 31)
The scale of a map shows the
relationship between a length on
a map and the actual distance it
represents on the Earth’s surface.
(Paragraph 1, line 2)
7. Why do we need a scale when
drawing a map?
Impossible for us to
draw a map the same
size as the actual area.
8. How scale is shown on a map (page 31)
Statement scale Line scale
1 cm represents 1 km
9. Large-scale map VS Small-scale map
Large-scale map Small-scale map
Smaller area of Earth’s Larger area of Earth’s
surface surface
More details Less details
12. As you are going through this,
please highlight in your textbook.
13. What is the definition of a topographical map?
Read the paragraph on page 45
A topographical map is an accurate
large-scale maps that gives details of
the physical and human features in an
area.
14. What are the uses of a topographical map?
You can find the answer on page 45
You use a topographical map to locate
specific places, as well as to understand
physical and human environment.
17. Eastings VS Northings
The numbers here are
increasing towards
North direction, thus
they are called
Northings.
The numbers here are
increasing towards East
direction, thus they are
called Eastings.
19. What is four figure grid reference?
It is a set of four numbers that is made
up of Northings and Eastings.
You should read EASTINGS
FIRST followed by NORTHINGS.
Remember: E comes earlier than N.
Eg. 0450 – 04 is the easting and 50 is
the northing.
20. Four figure grid reference
Step 1: For example, I
want to identify the four
figure grid reference of
this box.
21. Four figure grid reference
Step 2: Draw a cross
at the BOTTOM
LEFT CORNER of
the box.
22. Four figure grid reference
Read the corresponding
grid lines. Should your
answer be 0657 or
5706?
23. If you said 0657…
Give yourself a pat on
your back. You’re right.
IF you got this wrong,
please go back to slide
19 and revise.
25. What is six figure grid reference?
Six figure reference is like a more detailed
version of a four figure grid reference.
As the name suggests, there are SIX numbers.
06 57
The dotted boxes
refers to the
special numbers
that give the
EXACT position of
the feature you Easting Northing
want to find in the
map.
26. Six figure grid reference
Step 1: For example, I
want to identify the six
figure grid reference of
this box.
27. Six figure grid reference
Step 2: Zoom into
that particular box
28. You would
know from Six figure grid reference
earlier that the
four figure grid
reference is 0
0657 . Now we 9
need to find
the 2 special 8
numbers. Step 2: Divide
Step 1: Draw the 7
the grid square 6
mid points as
into ten equal 5
shown. 4
parts.

31. You are done!
NOW YOU NEED TO ATTEMPT
