The Rules…
1. Read the HORIZONTAL coordinate BEFORE the VERTICAL one… ‘Along the corridor & up the stairs’‘The baby crawls before it walks’
2. You read the coordinates from the BOTTOM LEFT HAND CORNER of the square you want to describe.

6 Figure Grid References
• To be even more accurate, we can divide grid squares up into smaller squares…
• Imagine that each grid square is divided into another 10 rows and 10 columns…

How do I use 6 figures?• You now use 6
numbers to describe a position…
• After you give the
main coordinate eg. 24, you then add a number 0-9 to describe where exactly the position is.
• For example,X=248115Z=242118
