Worksheet Overview

In this activity, we're going to be practising reading and comparing information in a selection of bar graphs.

Here is a bar graph showing the favourite subjects of a group of children:

What this graph is telling us:

- The range of subjects

- The number of children who liked each subject best (at the end of each bar)

- We have two labels to tell us what the information is representing (subjects and number of children)

Tip:  The total number is not usually included - we need to use the scale to read this information.  However, in this graph the total number for each subject has been included.

Example

How many more children like maths than English?

We find the bar for maths and read the total and do the same for English.

Maths = 10 children

English = 6 children

Subtract 6 from 10 to find the answer.

Four more children prefer maths.

Top Tip:  Check the scale on graphs - they do not always increase in ones.

Good luck with the following questions.
