A scale drawing is an accurate drawing of an object or landscape where the sizes have been enlarged or reduced by a given scale factor. Real life examples include technical drawings of objects, floor plans and maps. Scale models can be used alongside scale drawings. Scale models give an accurate 3D representation of an object. As with scale drawings, the real height/length/width of the object is scaled up or down to create the model.Β
When creating a scale drawing, we use a given scale. For example, a scale of 1:50 would mean that the drawing is 50 times smaller than the object. A real life measurement of 150 centimetres would be drawn with a length of 150 / 50 = 3 centimetres.Β
If we are looking at a scale drawing, we can work out the actual lengths using the scale. For example, if we had a map with map scale of 1:10000, a distance of 2cm on the map would give a real life distance of 2 * 10000 = 20000 cm, or 0.2km. The actual distance is 10000 times greater than the distance on the map.Β
Looking forward, students can then progress to additional ratio and proportion worksheets, for example a Β ratio worksheet or a simplifying and equivalent ratios worksheet.
For more teaching and learning support on Ratio and Proportion our GCSE maths lessons provide step by step support for all GCSE maths concepts.Β Β
