NARRATOR: Hello Snoot, hello Finn.
ALIENS: Alien language.
NARRATOR: I see you’re at the intergalactic market. Has anything caught your eye?
ALIEN: (Alien Language.)
NARRATOR: That looks like a toy puppy from Planet Earth, great choice!
What about you Finn?
ALIEN: (Alien Language.)
NARRATOR: Ah yes, on Earth, that’s called a squirt gun, it shoots water.
It looks like you’ll have to change your credits into Earth money if you want to buy anything from this stall.
On Earth, money comes in pounds and pence, and every pound is worth 100p.
That there is a ten pound note, which is worth ten one pound coins.
But will it be enough to buy the things you want?
Alien: Er……
NARRATOR: Let’s see, the puppy costs £3.50 and the squirt gun costs £5.50. Let’s start with the puppy.
£10 take away £3 will leave you with £7. Take away 50p and you’ll get £6.50.
Now for the squirt gun.
Take away £5 from £6.50 and you’ll have £1.50 left over. Take away 50p and there’ll be £1 change.
ÂŁ3.50 for the puppy, plus ÂŁ5.50 for the squirt gun makes ÂŁ9 altogether.
So you can buy both toys with your ÂŁ10 note.
£10 is £1 more than they cost together, so you’ll get £1 in change.
ALIENS: Ah ha!
NARRATOR: Finn! Don’t do it…
Oh dear.
Pounds and pence
Money comes in pounds and pence. One pound is the same as 100 pence.
Pounds are written with a ÂŁ before the number:
- for example two pounds is written as ÂŁ2.
Pence are written with a p after the number:
- for example twenty pence is written as 20p
Sometimes pounds and pence are written together as ÂŁ then the number of pounds then a dot then the number of pence.
- for example one pound and fifty pence is written as ÂŁ1.50
How do you add and subtract money?
If you are just working with pounds, or just working with pence, you can add and subtract just like with ordinary numbers.
If you are working with pounds and pence, remember that 100±č=ÂŁ1
Bridging through 100 can help. Here's what to do:
work out what you need to add to your first number of pence to make 100
add 1 to the pounds for the 100 pence
subtract what you added from the second number
the number you have left says how many pence you have
add this to the number of pounds you have for the final answer
Example
What is 70p + 40p?
What do you need to add to 70p to make 100p?
70p + 30p = 100p
This makes ÂŁ1.
Take 30p away from 40p
40p - 30p = 10p
Add this to the pounds to make ÂŁ1.10±č
