#### Worksheet Overview

We might sometimes think that we don't really need maths, but we are using it all the time, often without realising it!

Just think about going to the shops.  We need to make sure we have enough money to buy the things we want and check we are given the correct change!

What about playing a board game - we need to be able to add up the scores!

These are just two examples of how we use maths every day.

In this activity, we are going to practise using addition and subtraction to answer everyday word problems.

In some of the questions we will have to do more than one calculation, so reading the question carefully is very important!

Example

John and Carl take part in a competition to see how many books they can read over the summer.

How many more books did Carl read than John?

First, we need to identify the key information.

The question asks us how many more books Carl has read, so we need to find the difference, which means subtraction.

22 - 16 = 6

Carl read 6 more books than John.

Now let's look at another example, but this time we need to do more than one calculation!

Pens cost 50 pence each and pencils cost 25 pence each.

How much would 3 pens and 2 pencils cost altogether?

First, we need to work out the cost of 3 pens.

50 + 50 + 50 = 150 = £1.50 (150 pence is the same as £1.50)

Next, we work out the cost of 2 pencils.

25 + 25 = 50p

Finally, we add together the two totals.

£1.50 + 50p = £2.00 (200 pence)

The total cost is £2

Now, why don't you have a go at some questions like these?

Remember to read the question carefully and highlight the important information!
