Four Figure Grid References

A four-figure grid reference is a handy way of identifying any square on a map. Grid references are easy if you can remember that you always have to go:

"along the corridor before you go up the stairs"

To find the number of a square first use the eastings to go along the corridor until you come to the bottom left-hand corner of the square you want. Write this two-figure number down. Then use the northing to go up the stairs until you find the same corner. Put this two-figure number after your first one and you now have the four-figure grid reference, which looks like this: 2951

Six Figure Grid ReferencesDuring your expedition you will be expected to use 6 figure grid references, which are the same as 4 figure grid references but a little more precise.

If you want to pinoint an exact place on a map, such as your own house, you will need to use six-figure grid references.

First find the four-figure grid reference for the square and write it down with a space after each set of numbers, like this:

62_ 33_

Now imagine this square is divided up into 100 tiny squares with 10 squares along each side (almost like a decimal system in maths). Still remembering to go along the corridor and up te stairs, work out the extra numbers you need and put them into your four-figure grid referencelike this
