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: : cm on the map is 50000cm in real life. This means that 1cm = 500m or 0.5km

Geography Maps Draw 5 horizontal lines on your page. Let’s imagine a scale of 1: cm 8 cm 5 cm 3.2 cm 8.6 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.

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.

What is the distance of the A811? 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. Give a four figure grid square where the relief is: (a) Very steep(b) steep(c) gently sloping(d) flat
