The lesson focuses on understanding map scale and converting map measurements into real-world distances. Students will learn to measure both straight and curved line distances using techniques like the 'magic strip' method. By the end of the lesson, they will achieve various levels of proficiency in applying these skills.

1. Lesson objectives:
Knowledge:
All will understand what
we mean by scale
Most will explain how to
covert it into real world
distance
Some will explain the
technique to measure a
curved line on a map
Skills:
All will be able measure
straight line distances on a
map and covert them into
‘real world’ distance
Most will be able to
measure curved distances
(roads & rivers) and
convert them into ‘real
world’ distance

2. Keywords for today's lesson:
Scale
Distance
Kilometres (KM)
Centimetres (CM)
Measuring
Accuracy

3. Why do we use scale?
When we make a map … we shrink the real
world so that it can fit on a page
We use scale to do this…
Simply put, scale is how much the person
making the map has shrunk the real world

4. So how does it work?
Simply put, scale is how much the person
making the map has shrunk the real world
1cm on the map 4km in the real world

5. 0 1 2 3 4 5 6
Kilometres

6. 2cm = 1km
You can measure the
distance in cm
Try to be exact!
(Each extra mm = .1)
Then … divide by 2 to
change to km

8. 4cm = 1km
You can measure the
distance in cm
Try to be exact!
(Each extra mm = .1)
Then … divide by 4 to
change to km

12. Convert these scales
Scale 2cm = 1 km
1) 2cm
2) 4cm
3) 6cm
4) 7cm
5) 5cm
Scale 4cm = 1 km
1) 4cm
2) 2cm
3) 6cm
4) 7cm
5) 5cm
Quick recap

13. Answers
Scale 2cm = 1 km
1) 1km
2) 2km
3) 3km
4) 3.5km
5) 2.5km
Scale 4cm = 1 km
1) 1km
2) 0.5 km
3) 1.5km
4) 1.75 km
5) 1.25 km
Quick recap

14. How do we measure something
that isn’t straight?
Things like roads and rivers are bendy, but our
ruler is straight…
How can we measure them?

15. How do we measure something
that isn’t straight?
Step forward our hero

16. Activity
We are going to measure the distances between
points on your map using the ‘magic strip’
technique we have just watched
You need:
-Your ruler
-Pencil
-Your ‘Magic strip’
