Introducing line graphs
In this lesson you will learn how to read values from a line graph.
This lesson includes:
- two videos
- two activities
In this lesson you will learn about a type of graph you might not have seen before. It’s called a line graph.
We’ll start by questioning why we use graphs. Why don’t we just present the data in a table?
Watch the video below to see how a graph tells a ‘story’. Then you will learn about the different parts of the line graph.
Now you will learn how to read the information accurately by thinking about the horizontal axis and the vertical axis.
You will compare line graphs with bar graphs and think about why we need different types.
Have a look at the worksheet below. In question 1C, 2:30 pm is not marked on the horizontal axis. How will you find the temperature at 2:30 pm?
Write your answers on paper or print out the worksheet and fill it in.

These questions will build your confidence in reading values from a line graph.
Do you notice that the line is flat between 90 minutes and 120 minutes? Why do you think this is?
Write your answers or paper or print out and fill in the worksheet.
