What does four-figure grid references mean?
A 4-figure grid reference contains 4 numbers. The first two numbers are called the easting, which is the number you would look for at the bottom of the map. The second two numbers are called the northing and represent the numbers you would look for on the side of the map.
How do you explain grid references?
Grid references are used to locate a particular square on a map. This is important as it is a universal way for us to describe where things are on a map. The horizontal lines are called eastings as they increase as you move eastwards. The vertical lines are called northings as they increase as you move northwards.
How do you teach grid references?
Grid references
- First, find the four-figure grid reference but leave a space after the first two digits.
- Estimate or measure how many tenths across the grid square your symbol lies.
- Next, estimate how many tenths up the grid square your symbol lies.
- You now have a six figure grid reference.
How many figures does a grid reference have?
six
Grid references comprise six-figure numbers. Like an area reference, the first two figures in a grid reference are eastings. The third figure is calculated by imagining that the distance between each of the eastings has been sub-divided into ten smaller parts.
What is the golden rule for finding a grid reference?
The golden rule for reading grid references is always go along the X axis (the bottom) first and record those numbers first, then go up the side and record those numbers second. ‘Along the corridor & up the stairs’. Six Figure grid references allow you to locate a particular location on a map.
What is the difference between 4 figure and 6 figure grid references?
four-figure grid reference, such as ’19 45′, indicates a 1 km by 1 km square on the map; and. six-figure grid reference, such as ‘192 454’, indicates a 100 m by 100 m square on the map.
How do you read a 4 and 6 figure grid reference?
Things to remember:
- First, find the four-figure grid reference but leave a space after the first two digits.
- Estimate or measure how many tenths across the grid square your symbol lies.
- Next, estimate how many tenths up the grid square your symbol lies.
- You now have a six figure grid reference.
What are the four ways that scale can be expressed on a map face?
There are three main ways that scale is indicated on a map: graphic (or bar), verbal, and representative fraction (RF).
