This Geography scheme of work video demonstrates how to calculate the length of routes on maps using scale bars. Teachers are shown how to apply this skill to both straight and curved lines by first measuring the route (either with a ruler or a piece of string) and then converting the measurement using the map’s scale bar.

The video explores how the scale bar shows a ratio between map distance and real-world distance, typically in kilometres. It explains how straight-line distances can be measured and multiplied using the map’s ratio, while curved lines (like a river or winding road) require a flexible tool such as string to follow the shape before measuring. These techniques can be applied to a range of maps including Ordnance Survey (OS) maps, helping children to interpret geographical data and apply mathematical reasoning when analysing maps. This cross-curricular link supports both Geography and Maths objectives.

This video is part of Kapow Primary’s Geography – Fieldwork and map skills videos. It equips teachers with the confidence and clarity to model map measurement skills effectively.
