Aims:

1.  To know what is meant by the national grid

2.  To locate OS symbols on a map using grid references

3.  To give the correct grid references for features on an OS map.

The lines running across the page, ie from east to west are called Northings

The lines running and down the page, ie from north to south are called Eastings.

Every single square in the British Isles has a unique reference number. Some grid squares show very little:
