Lesson details
Key learning points
- A line graph is a way of representing the relationship between two variables.
- One variable is represented by the x-axis and the other by the y-axis.
- Points are plotted like coordinates with a value on the x-axis and a value on the y-axis.
Keywords
Line graph - A line graph is a graph where the points are connected by lines. It shows how something changes in value, usually over time.
Variable - A variable is something that changes and can also be measured.
X-axis - The x-axis is the horizontal line on a graph which goes through zero.
Y-axis - The y-axis is the vertical line on a graph which goes through zero.
Common misconception
Pupils may not understand that line graphs are only used for continuous data, where the points between those that are plotted have meaning.
Show children examples of graphs where there is no meaning between divisions on the x-axis (e.g. heights of children). Here, the points cannot be joined to make a line graph.
