Maps and Locations — Reading Maps and Using Directions
A map is a drawing that represents a real place, seen from above, drawn to a smaller size. Maps help us find places, understand distances, and give directions.
Key Ideas on a Map
Scale: A scale tells us what a distance on the map represents in the real world.
For example: Scale 1 cm = 10 m means that 1 cm on the map equals 10 metres in real life.
Directions: We use compass directions to describe location — North (N), South (S), East (E), West (W), and the intermediate directions NE, NW, SE, SW.
Grid / Coordinates: Many maps use a grid with letters for columns and numbers for rows (like a chess board). A location is given as a letter-number pair, e.g., B3.
Reading a Map
- 1.Find the scale.
- 2.Identify landmarks.
- 3.Use the grid to locate specific places.
- 4.Use compass directions to describe the position of one place relative to another.

On a map with scale 1 cm = 5 km, two towns are 4 cm apart. What is the actual distance?
Actual distance = 4 x 5 = 20 km
The library is at B4 and the park is at D4. In which direction is the park from the library?
Both are in row 4, but D is to the right of B — so the park is East of the library.
The school is North of the market. The hospital is South of the market. In which direction is the school from the hospital?
School is North of the hospital.
On a map, the river runs from grid C1 to C5. In which direction does it flow?
From C1 to C5, it moves from South to North — the river flows Northward.
Map scale is 1 cm = 2 km. The post office is 3.5 cm from the bus stand on the map. What is the real distance?
Real distance = 3.5 x 2 = 7 km
Common mistakes
- Reading the scale as "1 cm = 1 m" without checking what the scale actually says.
- Confusing East-West with North-South on the map.
Summary
Maps use a scale to represent real distances. Directions (N, S, E, W) and grids help locate places. Always multiply the map distance by the scale factor to get the real distance.
