Thank you for the post. I think the key issue here is the ratio conversion not necessarily scale. Most students understand that ratio colons ":" means "to", But some students try the hard conversion by trying to change cm to km while it is much easier to do the opposite. I agree they do know what a ratio is but I'm less sure they're familiar with ratios in the contexts of maps, which is why this particular GCSE question threw them. Thanks for a very interesting post.

Scale drawings are used to represent larger or smaller objects, drawings, images or maps. There are 6 skills you need to learn for scale drawings. Take a pre-assessment and understand what topic areas you need to work on to ensure you pass for level 2 maths exam first time. Scale factors are used to accurately scale up or down an image. Scale drawings will come with a key, or a scale factor, that tells you what a dimension in the drawing is equal to in real life.

Scale drawings represent real objects with accurate lengths reduced or enlarged by a given scale factor close scale factor The ratio of corresponding edge lengths, drawing to real life. Scale drawings close scale drawing An accurate drawing, or model, of a representation of a physical object in which all lengths in the drawing are in the same ratio to corresponding lengths in the actual object. Scale drawings may also be a larger representation of small objects such as parts for a watch or a medical instrument. Scales are expressed in ratio close ratio A part-to-part comparison. In a scale drawing, all dimensions have been reduced by the same proportion and measurements are most often in centimetres and millimetres. For example, 1 cm on a scale drawing representing 1 metre in real life is a scale of 1 : When writing and using scales, understanding conversion between units, simplifying ratios and solving ratio and proportion problems can help.

Here we will learn about scale drawings, including creating scale drawings, using scale factors, and word problems. An enlargement changes the size of an object by multiplying each of the lengths by a scale factor to make it larger or smaller. In order to interpret and produce scale drawings we need to know the scale factor and the actual lengths of the object.
