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
Using coins, we can make £4 using four £1 coins.
So £4 could be written as 4 × £1.
Using coins, 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.
Which coins could be used to make £2.24?
To make £2.24, we would need two £1 coins.
We would also need to make 24 pence, which could be done in several ways.
Here is one way: 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.
