Video summary
We see a demonstration of converting distance on a map to real-life distance and learn how to calculate scale factor given the actual distance on a map.
Reading coordinates and placing coordinates on a set of axes is explained, which leads on to enlargement using scale factors on a coordinate plane.
An example of calculating unknown sides of an enlarged shape is shown.
The end sketch illustrates the idea of proportion.
This clip is from the series Kick Sum Maths.
Teacher Notes
Pupils could use scale factors to enlarge shapes on a coordinate plane or to read maps.
They could create scale drawings and models of objects or places, for example a map of the school.
These clips could be used for teaching Maths at KS2 or at a beginner level in England, Wales and Northern Ireland and 1st and 2nd Level in Scotland.
