1. Objective;To use four figure grid references

2. Four-figure grid references (1)
Four-figure grid references are used to identify and locate particular squares on a map. To create four-figure grid references you use the grid lines on a map 39
The vertical lines on the grid are called EASTINGS and they increase in value as you move EASTwards. 38 37
The horizontal lines on the grid are called NORTHINGS and they increase in value as you move NORTHwards. 36 35

3. Four-figure grid references (2)
In order to locate a particular square, find the bottom left-hand corner and write down the numbers of the lines which pass through the corner
The EASTING (vertical) line is number 24 39 38
The NORTHING (horizontal) line is number 37 37
So, the four-figure grid reference is: 36 24 37

REMEMBER:
Eastings number first
Northings number second

Lets have a look at a couple of other examples. You work out the answer before it appears!
First, a RED SQUARE 39
The EASTING is: 22 38
The NORTHING is: 36 37
The four-figure grid reference is: 36
2236 35 21 22 23 24 25 26

Final chance to practice…..
This time, a BLUE SQUARE 39
The EASTING is: 24 38
The NORTHING is: 35 37
The four-figure grid reference is: 36
2435 35 21 22 23 24 25 26
