There are four books on one shelf and five books on another. How many books are there altogether?

There are five books on this shelf and four books on this shelf. How many books are there altogether? We need to work out what five plus four is. We can use a number line to help us.

We can start counting at number five and add four more. To do this, we need to count forward four times: one, two, three, four. Five plus four equals nine. There are nine books altogether.
