Counting Money: Pounds and
Piastres
In this video, we’re going to be
learning how to find the value of a group of notes and coins in pounds and
piastres. This is Dalia, and this is her
savings tin. She’s been saving for a while
now. And she’s hoping she’s got about 30
pounds. Let’s open the tin to count the
money that Dalia has. There we are. No wonder her tin was so heavy. As well as notes, Dalia’s tin also
contains some coins. Before we count them, we need to
check that we recognize these notes and coins.
The notes that Dalia has are all
the same value. Can you see? They’re all worth five pounds or
five LE. Then if we look at her coins, we
can see that she has three one-pound coins. But this coin is slightly
different. If we zoom in on it, we can see
that it’s worth a number of piastres, not pounds. This coin is worth 50 piastres. So to find the total value of these
notes and coins, we’re going to need to count the pounds and then the piastres.
Let’s start with the pounds. And if we add our pounds in order
of value, it’s going to be a little bit easier for us to find a total. So we’ll start with the largest
amount. And these are our four five-pound
notes. What are four fives worth? Five, 10, 15, 20 pounds. Now don’t forget because we’re
trying to find the total number of pounds we’ve got, we can’t just stop with the
notes because some of our coins are worth pounds too. We need to add on three more
pounds. 20 pounds plus three more pounds
equals 23 pounds.
Finally then, we need to count how
many piastres Dalia has. But because we can see the only
coin we need to think about is this one worth 50 piastres, we don’t need to draw a
number line. Dalia can say that she saved 23
pounds and 50 piastres. It’s not quite the 30 pound she was
hoping for, is it? But she’s getting there.
By the way, did you notice what
skills she needed to be able to find this total amount of money? Firstly, she needed to be able to
identify the different notes and coins that she had, then to be able to put them in
order first the pounds and then the piastres to make them easier to add. And then, thirdly, we used the
skill of skip counting where possible. We had four five-pound notes. Instead of adding five plus another
five plus another five and so on, we just skip counted in fives four times, much
quicker.
Meet two of Dalia’s friends, Karim
and Mariam. Who do you think has the most
money? Well, if we look really quickly, we
can see that both friends have four notes. But Mariam has more coins. But we know that just because
somebody has more notes or more coins doesn’t mean they have more money. We need to start looking at the
value of these notes and coins.
Let’s begin with Karim. And let’s think about those three
skills that we’ve talked about already. Firstly, let’s identify the notes
and coins that Karim has. There are two 10-pound notes. And this next note is an
interesting one. It’s a lot of money. Let’s look at it more closely. I wonder, have you ever seen one of
these before? This note has a value of 200 LE or
200 pounds. Just because this is the first time
you may have seen one of these, this is what the front of this note looks like. So as well as his two 10-pounds and
one 200-pound notes, Karim also has a 20-pound note. And if we look carefully at his
coins, we can see that this coin is worth another pound too.
So all these notes and coins
represent amounts of pounds. But we can also see that Karim has
this coin worth 50 piastres too. So now that we’ve identified all
these notes and coins, we need to put them in order before we add them. Perhaps you can see that this time
we’re not given the notes in order. The note with the greatest value,
that’s that 200-pound note we spotted, is hidden between the 10-pound note and the
20-pound note. So let’s add these amounts in
order.
Now because we know the note with
the greatest value is 200 LE, we could start counting from 200 rather than zero. 200 plus 20 equals 220. And now we need to add two notes of
the same value. So we can apply our third skill of
skip counting, 230, 240. And if we add our one-pound coin,
we can see that Karim has 241 pounds. And not forgetting the coin that’s
worth 50 piastres, Karim has 241 pounds and 50 piastres.
Now let’s see whether Mariam’s
larger pile is worth more or less. She has a 100-pound note, two
50-pound notes, a 20-pound note, two one-pound coins, and two coins worth 25
piastres each. Now we’ll start by adding the
number of pounds that Mariam has. And once again, we’re going to put
them in order. We won’t start counting from zero;
we’ll start counting from the note with the largest value. That’s the 100-pound note. Now we need to skip count twice in
50s, 150, 200. Add the 20-pound note takes us to
220. And instead of adding on one twice,
we can simply add another two pounds for our two-pound coins. Mariam has 222 pounds.
Now we’re already in a position
really to see who has most money. But let’s just add how many
piastres she has. We know that 25 plus 25 equals
50. And so Mariam’s two coins have a
value of 50 piastres. Mariam has a total of 222 pounds
and 50 piastres. Now when we compare two amounts of
money like this, we first look at the amount of pounds. Pounds are worth more than
piastres, so they matter more when we compare them. Karim has 241 pounds. Mariam has 222 pounds. And because we know 241 is greater
than 222, we can say that the person with most money is Karim.
Let’s have a go at answering some
questions now where we have to find the value of a group of notes and coins in
pounds and piastres.
Complete using the symbol for is
equal to, is greater than, or is less than.
Can you see where our missing
symbol belongs? It’s in between one, two groups of
money. And we’re going to have to find the
total of each group to be able to compare them. Perhaps you spotted that we were
going to need to find some totals by these little addition symbols that’re in
between the notes and the coins.
To start with, let’s look at our
first group. We can see that this group contains
both notes and coins. And they all have a value of a
different amount of pounds. Can you spot them? Firstly, we’ve got a 200-pound
note. Then we have three notes that are
worth all the same amount, 10 pounds. And each of these four coins are
worth one pound. So what is 200 plus three lots of
10 plus four lots of one? Let’s use a number line to help
us. And rather than starting from zero,
we could start from our first note, 200. Now to add our three 10-pound
notes, we could skip count in 10s three times. 210, 220, 230.
Now finally, we could add our four
one-pound coins one at a time, but it might be a bit quicker just to add four all in
one go. 230 plus four is 234. The total of our notes and coins on
the left is 234 pounds.
Now let’s look at the amount of
money on the right. This time, we haven’t got any coins
to add. Our first two notes are worth 100
pounds each. Then there are four 10-pound notes
and two five-pound notes. This time, the value of our largest
note is 100 pounds. So let’s start counting from
there. And we can begin by adding our
second 100-pound note. That takes us to 200. Now we’ve got four 10-pound notes
to add, so let’s skip count in 10s four times. 210, 220, 230, 240.
Finally, we need to add our two
five-pound notes, so we’re going to skip count in fives twice. 245, 250. So our first group was worth 234
pounds, but our second group has been worth 250 pounds. And we know that 234 is less than
250. So the value of our first group of
notes and coins is less than the value of the second. The correct symbol we need to use
to compare these two groups of money is less than.
Count the amount of money
shown.
In this picture, we can see a group
of notes and coins. And to find out the amount of money
shown, we need to add them together. Shall we start with this one-pound
coin and then perhaps add some of the other amounts of money? Well, it doesn’t really make sense
to do this. When we’re working out an addition,
it’s a little bit easier if we start with the larger number first. And in the picture that we’ve been
given, the note or the coin with the largest value are these notes here. They’re 10-pound notes.
Now, if we start counting from one
of our 10-pound notes and add the other one, we have 20 pounds altogether. Next, we need to add this
five-pound note. 20 plus five is 25. But we can’t just stop counting the
pounds there. One of our coins is worth an amount
of pounds too, one pound. So 25 pounds becomes 26 pounds. Now we’ve counted all the notes and
coins that have a value of pounds, but we’ve got one coin left. Do you recognize it? It’s worth 50 piastres. So the amount of money that we can
see here is a number of pounds and some more piastres.
We used a number line to help us
find the total amount of money shown. And that amount is 26 pounds and 50
piastres.
A toy store has the following items
for sale at the following prices. How much does the teddy bear
cost? How much does the ball cost? And how much does the train
cost?
This question is all about three
toys that are for sale in a toy store: a teddy bear, a ball, and a train. Now not only can we see these three
items, but we can also see how much they cost. We’re shown their prices. Now normally, when you go to shop
and you see the price of something, you might see a little label with some numbers
on it. This question is a little bit
different because if we want to work out these prices, we’re going to have to add
together the picture of the notes and the coins that we can see underneath each
object. It’s obviously a toy store for
people who love maths because we’ve got to do some working out to find out these
prices.
Our first question asks us the
price of the teddy bear. How much does this cost? Well, let’s take a moment to look
at the notes and the coins underneath the teddy bear. What can you see? Our note is worth 10 pounds. And we’ve also got three one-pound
coins. That’s worth three pounds
altogether, isn’t it? And we know that 10 plus three
equals 13. The teddy bear costs 13 pounds.
Next, we’re asked about the
ball. How much does the ball cost? Again, let’s look carefully at the
notes and the coins that we have and add them together. We’ve got a 20-pound note and then
a five-pound note. Add 20 plus five equals 25. That’s all the notes sorted
out. But what about the coins? Although we’ve got 25 pounds
already, one of our coins is also worth an amount of pounds. It’s a one-pound coin. This takes us up to 26 pounds. But can you see our second coin is
worth less than a pound? It’s worth 50 piastres. Our ball costs an amount of pounds
and some more piastres. It costs 26 pounds and 50
piastres.
Finally, we need to work out how
much the train costs. The price of this train is only
represented by two notes. Do you think this means it’s going
to be cheaper than the other toys? Let’s find out. Our first one’s a big one; this is
a 50-pound note. And our second note is a five-pound
note. And 50 plus five equals 55. It looks like it doesn’t really
matter how many notes or coins you have, but what value they are. That 50-pound note at the top there
really made this train very expensive.
We’ve calculated the prices of
these three toys by adding up the value of the notes and the coins underneath. The teddy bear costs 13 pounds, the
ball costs 26 pounds and 50 piastres, and the train costs 55 pounds.
What have we learned in this
video? We have learned how to find the
value of a group of notes and coins in pounds and piastres.
