Use compass directions
Theory
A compass has four main points, north, east, south and west, and four in-between points: north-east, south-east, south-west and north-west. This Year 5 maths page shows how to give the direction of one place from another, how to describe routes, and how to work out which way you face after a quarter, half or three-quarter turn.
Going clockwise around the compass: N, NE, E, SE, S, SW, W, NW. Each main point is a quarter turn (\(90^\circ\)) from the next main point.
The opposite of a direction is a half turn away: north and south, east and west, north-east and south-west, north-west and south-east.
“The lookout is north-east of the tent” means: stand at the tent and face the lookout; you face north-east.
A quarter turn is \(90^\circ\), a half turn is \(180^\circ\), a three-quarter turn is \(270^\circ\) and a full turn is \(360^\circ\). Clockwise is the way clock hands move; anticlockwise is the other way.
Turns and opposites:
Opposites: N and S, E and W, NE and SW, NW and SE.
How to give the direction of B from A
- Stand at A (the place after “from”).
- Look towards B: is it up or down the page (north or south), left or right (west or east)?
- Combine: up and right is north-east, down and left is south-west.
How to make a turn
- Start at the direction you are facing on the compass rose.
- Move around it: a quarter turn is two steps of the eight points, a half turn four steps.
- Go clockwise or anticlockwise as told.
C is to the right of T in the same row: east.
L is 2 squares right and 2 squares up from T: north-east.
The opposite of north-east: south-west.
B1 to B3, then B3 to E3.
(ii) Facing north-west, you make a quarter turn clockwise. Which way do you face?
(i) North
(ii) North-east
| \(3 \times 90\) | \(=\) | \(270^\circ\) |
West, then south, then east: you face east, having turned \(270^\circ\).
The opposite direction: north-west.
The direction depends on where you start. From the lookout, the tent is down and to the left, so it is south-west of the lookout.
Common pitfalls
Frequently asked questions
What are the eight compass points?
North, north-east, east, south-east, south, south-west, west and north-west.
What is the opposite of north-east?
South-west.
How do the turns compare?
A half turn is two quarter turns, a three-quarter turn is three quarter turns, and four quarter turns make a full turn.
Which way is clockwise?
The way the hands of a clock move: from north towards east.
How do you find the direction of one place from another?
Stand at the first place named after “from” and see which way you would face to look at the other place.
