Grid references are used to locate features on a map using a system of vertical and horizontal lines. Eastings are vertical lines numbered eastward to measure distance, while northings are horizontal lines numbered northward. A location is determined using a four-figure grid reference indicating a feature's location within a grid, using the easting followed by the northing, or a more precise six-figure grid reference dividing each grid into ten parts and including the easting and northing subdivisions.

2. • The network of vertical and horizontal lines used for locating features
on a map.
• Eastings- Vertical lines numbered eastward to measure distance.
• Northings- Horizontal lines numbered northward.
• The location of a place is determined using four figure and six figure
grid references.

3. 1. Four Figure Grid Reference
• It indicates a location of feature on a particular grid.
• Use easting followed by northing while reading four figure grid
reference.

4. 2. Six Figure Grid Reference
• Six figure grid reference is used to find exact location of a feature
within a grid.
• Each grid is divided into ten equal parts.
• Use easting along with its sub division followed by northerning and its
sub division.

6. Learning Activity
