Map Scale & Distance

Starter: Draw a quick (really quick) map of the classroom in your books.

L.O: Identify distances on maps of varying scales – Local, national, global.

Distance – Large vs Small Scale

Maps are simply smaller drawings of any area.

They may be large or small scale maps Large scale maps show things as being

fairly large Small scale maps are more zoomed out

to show a large area.

For example…

Distance - Scales

Maps are made as small representations of what we can see

Scale drawing allows us to draw large objects on a smaller scale while keeping them accurate.

All scale drawings must have a scale written on them. Scales are usually expressed as ratios.

Example: 1cm : 1km

The ratio 1cm:1km means that for every 1cm on the scale drawing the length will be 1km in real life

Distance - Scales

Maps will always have a scale as a ratio as explained, and usually also have a linear scale for use to measure from.

To use this linear scale, place a piece of paper on the map and mark point A and point B, then work out distance on the scale.

For curves you can use a piece of string.

Where are we on our progress line?

How much progress have you made?

I fully understand the LO

I’m not really sure what the LO is about

Homework

Using ‘Google Earth’ calculate the following: Distance from your house to ACS

Cobham in a straight line The distance using roads (indirect).

You will need to do this on a PC as the iPad app doesn’t allow for route marking.
