By the end of the lesson students should be able to -understand you can give your position using a grid reference -explain some tasks/jobs that require a grid reference to be used -to give 4 & 6 figure grid references

1. Lesson objectives:
Knowledge:
All will understand you
can give your position
using a grid reference
Most will explain some
tasks/jobs that require a
grid reference to be
used
Skills:
All will be able to give a 4
figure grid reference
Most will be able to give
4 & 6 figure grid
references
Some will combine grid
references & direction to
give a location on a map

2. Keywords for today's lesson:
Compass
Direction
Grid reference
Map
Key phrase for today:
“Along the
corridor and
up the stairs”

3. First, let’s revise our compass directions …

9. 4 Figure Grid References
Used in Ordnance Survey maps to
locate a position

10. Northings
They run from North to South

11. Eastings
They run from one West to East

12. Grid References
Joined together they form a grid

13. Co-ordinates
These help us identify the line by having a
number on them
23 24 25 26

14. Co-ordinates
We do the same with the
Eastings
01
02
03
04

15. Grids
Remember we joined the Northings and Eastings
together before. We do the same again including the
numbers

24. How well did you do?
10 Outstanding!
7-9 Tremendous
6-8 You’re doing OK
4-5 Keep practicing
0-3 Ask for some help

25. 6 Figure References
These are used to give an accurate
position. Usually accurate to a 100
metres.

26. A 6 Figure reference looks like
this
GR 234678
Grid Reference Northings and Eastings

27. How do we get a 4 figure Grid Reference?
First we identify the square like we did before
22 23 24 25 26
01
02
03
04

28. Square 2402
We divide the square up into 10 equal lines
Eastings

29. Square 2402
Now we add the Northings

30. The Square 2402
Now we add the Northings and Easting numbers
1 2 3 4 5 6 7 8 9 0
1
2
3
4
5
6
7
8
9

31. 22 23 24 25 26

03
04
We read the Easting first = 24
Next we read the Northing = 02
Reading the reference

32. Reading the reference
Now we have the Northing and Easting
numbers, write it down like this
24 02
Leave a space for the third number
and last number shown in yellow

33. Reading the square 2402
1 2 3 4 5 6 7 8 9 0

1. Like in the grid
before read the
Eastings first
2.Then read
the
Northings
= 5
= 4

34. Now What?
REMEMBER
24 025 4
1.Easting
2.
Northing
Then we put the Northing 4 into the last place
We put the easting 5 into the third space

35. The 6 figure reference
The reference is now complete
