In this activity, we will be learning how to make amounts in pounds and pence using different coins.

It is useful to remember the following facts:

 

Ten 10p coins = £1

One hundred 1p coins = £1

 

We can make £4 using four £1 coins.

So £4 could be written as 4 × £1.

 

We can make £4.20 with four £1 coins and two 10p coins.

So, £4.20 can be written as 4 × £1 + 2 × 10p

 

To make £4.28, we would need to use four £1 coins, two 10p coins, and eight 1p coins.

So, £4.28 can be written as 4 × £1 + 2 × 10p + 8 × 1p

 

 

Let's try an example question.

 

Example

Which coins could be used to make £2.24?

 

Answer

To make £2.24, we would need two £1 coins (this would give us £2)

 

We would also need to make 24 pence, which could be done in several ways. 

For example, we could use one 20p coin and four 1p coins.

 

So, £2.24 could be written as 2 × £1 + 1 × 20p + 4 × 1p

 

Now you've tried the example, you're ready to try some questions about this.
