Geography Maps Scale and Using an OS Map [Date] Today I will: - Learn how to use a scale - Bring together the skills I have learned to effectively read a map.
Geography Maps Objects can be scaled up or down in size. On an OS map the scale is written like this: 1: 50000 1 cm on the map is 50000 cm in real life. This means that 1 cm = 500 m or 0. 5 km 1: 25000
Geography Maps Draw 5 horizontal lines on your page. Let’s imagine a scale of 1: 50000 10 cm 8 cm Because the scale is 1: 50000 you work out the distance in real you multiply the number of cm by 0. 5. This will give you an answer in km. 5 cm 3. 2 cm 8. 6 cm
Geography Maps Draw 3 bendy lines on your page. Let’s imagine a scale of 1: 50000 To work out a distance that is not a straight line you use a piece of paper and mark on the points.

Contour lines Numbers for grid references
Geography Maps 1. What symbol is at: (a) 650, 949 (b) 737, 941 (c) 663, 955 (d) 649, 948 2. What is the highest height on the map? Give a six figure grid reference of this point. 3. What is the distance of the A 811? Remember your units. 4. What contour line is at 680, 917? 5. What is the straight line distance between: (a) Little Kerse and Wester Frew (b) Culbeg and Cambusdren? 6. What is the direction from: Little Kerse to Wester Frew (b) Cambusdren to Culbeg? 7.
