Lesson video

Hello, my name's Mrs. Cornwell and I'm going to be helping you with your learning today.

We're going to be finding out all about money.

So we're going to find out how we can use what we already know to help us with our learning, and we're also going to find out how we can work in the most efficient way.

Okay, so I know you're going to work really hard in today's lesson and I'm really looking forward to it, so let's get started.

So our lesson today is called Recognise and understand the value of different coins, and it comes from the unit, Recognise coins and use the pounds and pence symbols.

So in our lesson today we're going to be looking at the values of different coins, some silver coins and some bronze coins, and we're going to be working out how we can find their value, and what we can use that we already know to help us with that.

So let's get started.

So here are our key words for today.

Value, my turn, value.

Your turn.

And worth, my turn, worth.

Your turn.

And coin, my turn, coin.

Your turn.

Well done.

Okay, so in the first part of our lesson we're going to find the total of a set of same-value coins, okay? And in our lesson we've got a lot of people helping us with our learning today, haven't we? We've got Jacob and Jun and Sofia and Izzy.

So the children have been collecting coins so they can visit the amusement arcades.

That sounds like fun, doesn't it? I wonder if you've ever visited the amusement arcades? Let's see what we already know about each coin they collected.

And here are some of those coins.

So first of all, this one.

Hmm, what do we know about this? That's right.

This is a 1 p coin.

It has a value of 1 p or 1 pence.

It is bronze and you can use it to pay for items, can't you? Now this one is a 2 p coin, isn't it? What else do we know about our 2 p coin? That's right, it has a value of 2 p or 2 pence.

And it's bronze as well, isn't it? And you can use it to pay for items as well.

Oh, now this one is a 5 p coin, isn't it? That's right.

And what do we know about this? It has a value of 5 p or 5 pence, that's right.

It is silver and you can use it to pay for items, can't you? And this last one, that's right, is a 10 p coin.

It has a value of 10 p and it is silver.

And you can also use that to pay for items, can't you? So well done, if you thought of those things.

Perhaps you could collect a set of these coins together and ask what is the same and what is different about them all.

You could carefully have a look at them and see what else you notice.

So Izzy counts the 1 p coins.

Sofia counts the 2 p coins, Jacob counts the 5 p coins, and Jun counts the 10 p coins.

There, they've sorted them there, haven't they? Sofia and Jacob both think they have the most money.

Hm, let's have a look at the coins they've got there.

Sofia says, "I will have the most money because my coins are the largest." So the 2 p coins are larger than any of the other coins, aren't they? And Jacob says, "No, I will have the most money because I have the most coins." So he's got more coins than anybody else there.

Jun and Izzy disagree.

Let's find out who is right.

I wonder what you think about this.

Well, we need to decide the value of each coin before we can count them, don't we? So there's Izzy with her coins and her coins are, that's right, 1 p coins.

The 1 p coins are easy to count.

Each coin has a value of 1 p, so we can count them in ones, can't we? Each coin has a value of 1 pence.

Each coin can be represented by a one-spot token.

And that's one spot just reminds us of the 1 pence it represents.

So let's count: 1 p, 2 p, 3 p, 4 p.

"The coins I had were worth 4 p," says Izzy.

Now let's look at Sofia's coins.

I wonder how much those are worth.

2 p coins have a different value.

We don't count those in ones, do we? So here are the 2 p coins.

We know that each 2 p coin represents a group of two 1 pennies, don't we? We see 2 p, but we think 2 pennies.

Each coin can be represented by a two-spot token.

And the two spots on the token just remind us of the 2 pennies, don't they? Each coin has a value of 2 p, so we can count them in twos.

2 p, 4 p, 6 p, 8 p, 10 p.

Well done, if you spotted that and you'd already worked that out.

So there's Sofia and she's just saying, "The coins I had were worth 10 p." Now let's find the value of the 5 p coins, Jacob's coins here, he had the most coins, didn't he? I wonder if he's got the highest value? So there are his 5 pence coins.

We know that each 5 p coin represents a group of five 1 pennies.

We see 5 p but we think 5 pennies.

Each coin can be represented by a five-spot token.

Each spot on the token reminds us of a penny, doesn't it? So we know each token is worth 5 pennies.

Each coin has a value of 5 p, so we can count them in fives.

5 p, 10 p, 15 p, 20 p, 25 p, 30 p, 35 p, 40 p.

"The coins I had were worth 40 p," says Jacob.

Now let's find the value of the 10 pence coins.

Oh, so I wonder if Jacob did have the most? So there are the 10 pence coins.

We know that each 10 p coin represents a group of 10 1 pennies.

We see 10 p, but we think 10 pennies.

Each coin can be represented by a 10-spot token, can't it? Just to remind us of the value.

Each coin has a value of 10 p, so we can count them in tens.

10 p, 20 p, 30 p, 40 p, 50 p.

So, "The coins I had were worth 50 p," says Jun.

So who did have the most money there then? Even though there were more 5 p coins and the 2 p coins were larger, the 10 p coins had a greater value, didn't they? So they were worth more.

And we can see, there they are, we had, only had five coins, but they were worth 50 pence, weren't they? So they were worth the most.

So well done, if you spotted that.

Okay, so now it's time to check your understanding again.

Predict which set of coins has the greatest value.

Then count them to check you were right.

So we can see that there are six 10 pence coins, six 5 pence coins, and six 2 pence coins.

So pause your video now while you decide which set will have the greatest value.

Okay, and which set did you predict would have the greatest value? Did you predict the 10 pence coins? That's right.

There are the same number of coins in each set, but 10 pence is worth more than 5 pence or 2 pence.

So we can predict even before we count that the 10 pence coins will be worth more, can't we? And now let's count them to see if we were right.

10 p, 20 p, 30 p, 40 p, 50 p, 60 p.

So the 10 pence coins were worth 60 p, weren't they? What about the 5 pence coins? 5 pence, 10 pence, 15 pence, 20 pence, 25 pence, 30 pence.

So the 5 pence coins were worth 30 pence.

And then finally the 2 pence coins.

2 p, 4 p, 6 p, 8 p, 10 p, 12 p.

So we know that the 2 pence coins were worth 12 p.

So well done, if you noticed that.

Our prediction was correct, wasn't it? The set of 10 p coins are worth more because each coin has a greater value.

Okay, so here's the children again.

Each child collects some more money.

Let's see how much money each child has.

Sofia has only 2 p coins.

We see 2 p, but we think 2 pennies, we must count them in twos.

So 2 p, 4 p, 6 p, 8 p, 10 p, 12 p, 14 p, 16 p, 18 p.

Sofia has 18 p.

Jacob has only 5 p coins.

We see 5 p, but we think 5 pennies.

We must count them in fives.

So let's try, 5 p, 10 p, 15 p, 20 p, 25 p, 30 p, 35 p, 40 p, 45 p, 50 p, 55 p, 60 p, 65 p.

So Jacob has 65 p.

And then Jun has only 10 pence coins.

We see 10 p, but we think 10 pennies.

We must count them in tens.

So here we go.

10 p, 20 p, 30 p, 40 p, 50 p, 60 p, 70 p, 80 p.

Jun has 80 p.

So even though Jun had the fewest amount of coins, he actually had the most money, didn't he then? The highest value, because his coins are worth more, the 10 pence coins.

Well done, if you noticed that.

Okay, so now the children are going to play a game.

This sounds like fun, doesn't it? The children play a game where they hide their coins from each other but describe the number of coins.

The other children have to work out their value.

"I have seven 2 p coins." says Sofia, "How much money do I have?" Oh, I wonder if you could think about that.

Jun has a strategy to work it out.

He says, "I will use my fingers to represent each coin." So each time he puts a finger up that will represent one of her 2 p coins.

"There are seven coins, so I will hold up seven fingers." And there are the seven fingers, look.

"I will count in twos until I have counted 7 fingers," because each finger is representing 2 p, isn't it? Okay, 2, 4, 6, 8, 10, 12, 14.

"You have 14 p altogether," says Jun.

Hm, that was a good strategy, wasn't it? "I will draw the coins and record this as a multiplication equation," says Jun.

So he draws the seven 2 p coins, and have you noticed he's put in a number 2 inside each coin instead of drawing the two dots? Because that's more efficient, it's quicker, isn't it? And then he's written a multiplication, 7 x 2 p = 14 p.

Now Jacob poses a problem for Sofia.

"I have five 5 pence coins.

How much money do I have?" Oh, I wonder if you can use his strategy that he used before.

"There are five coins, so I will hold up five fingers," says Sofia.

So there's the five fingers.

This time each finger is representing a 5 p coin.

So she needs to count in fives, doesn't she? "I will count in fives until I have counted five fingers." 5, 10, 15, 20, 25.

"You have 25 p altogether," she says.

"I will draw the coins and record this as a multiplication equation." And this time she writes a number 5 instead of drawing five dots, doesn't she? And then she writes the multiplication, 5 x 5 p = 25 p.

Okay, so now it's time to check your understanding.

Counting tens on your fingers to find the total value of Jun's coins.

And he tells us how many he's got there, doesn't he? "I have eight 10 p coins.

How much money do I have?" Perhaps you could predict using your multiplication facts to help you first and then use your fingers to find out if you're right.

So pause the video now while you have a try at that.

Okay? And let's see how you got on.

So there are eight coins, so you had to hold up eight fingers.

I will count in tens until I have counted eight fingers.

10, 20, 30, 40, 50, 60, 70, 80.

You have 80 p altogether.

So well done, if you did that.

We can draw the coins and record this as a multiplication equation, can't we? So how many coins will we draw? That's right, eight coins.

Each one's worth 10 pence, so we'll write a number 10 in each coin, and then the multiplication is 8 x 10 p = 80 p.

So well done, if you did that.

Okay, so here's the task for the first part of our lesson.

Play a game with a partner.

You will need a bag of ten 2 p coins, a bag of ten 5 p coins and a bag of ten 10 p coins.

"We will take it in turns to pick out a handful of coins from one bag, say which bag it was picked from, and how many coins were picked out," says Jun.

"When you pick the coins, I will skip count on my fingers in either twos, fives, or tens to find the total value of your coins," say Sofia.

"I will also use skip counting to see if you're right," says Jun.

"Then I will record it as a multiplication equation, for example, saying 4 x 5 p equals 20 p." Okay, so if you don't have that many coins, you could always use different coloured counters to represent the coins, couldn't you? Or you could imagine how many coins you've picked out of a bag and say, for example, "I've picked five 2 p coins," and then you could count on your fingers to work out the value and then draw them to represent it.

So now it's time for the second part of your task.

Jun and Sofia have a bag of 5 p coins.

Use the clues to find out how much money could be in the bag.

Well, we know they are 5 p coins and here are some clues.

There are fewer than 10 coins in the bag.

There are more than 5 coins in the bag.

Then draw the coins and write a multiplication equation to show the amounts.

So you're finding all the different possible amounts, aren't you? Work systematically in an order to find all the possibilities.

And again, if you don't have the coins available, you could use counters to represent the coins, and counting fives for each counter, couldn't you? Okay, so pause the video now while you try that.

So let's see how you got on.

You may have done this.

Here's Jun saying, "I have five 5 p coins." And there's Sofia saying, "I will put up five fingers to represent those coins and skip count in fives using one finger for each number counted." So there's the five fingers.

5, 10, 15, 20, 25.

So the total value of your coins is 25 p.

"I will draw the coins and record the multiplication equation." So there's the five 5 p coins, and 5 x 5 p = 25 p.

So well done, if you did that.

Okay, so now let's look at the second part of our task.

You may have done this.

So we've got a bag of 5 p coins, and we know there are fewer than 10 coins in the bag, but more than 5, don't we? So Sofia says, "I will think about which numbers are between 5 and 10." That will help us.

6 is between 5 and 10, there could be six coins.

So let's draw six 5 p coins, and the multiplication will be 6 x 5 p = 30 p.

So there could be 30 p in the bag.

Okay, so what else could be in the bag then? So between 5 and 10, that's right, 7 is between 5 and 10, there could be seven coins.

Okay, and how will we work out the total value of these coins then? So 5 more than 30 p is 35 p.

So we knew six 5 p coins was equal to 30 p, so 5 more would be 35 p.

So there could be 35 p in the bag.

And the multiplication equation for that is 7 x 5 p = 35 p.

What could be next then? We've had six coins, seven coins, that's right, 8 is between 5 and 10.

So we could have eight coins, couldn't we? How can we work out the value of those eight coins, I wonder? That's right, we could think, "Oh, it's five more than the seven coins." So 5 more than 35 pence is 40 pence.

So there could be 40 p in the bag, couldn't there? And the equation is 8 x 5 p = 40 p.

What's next then? That's right, nine 5 p coins would be next, wouldn't it? Okay, and the value of nine 5 pence coins would be, that's right, 8 fives are 40, so 5 more than 40 pence is going to be 45 pence.

There could be 45 p in the bag, couldn't there? 9 x 5 p = 45 p.

So you may have added one more 5 pence each time like I did there, or you may have already known how many would be there from your multiplication facts.

So well done with that.

Now, in the second part of our lesson we're going to find the total of a set of coins with different values.

The children put their coins together, so now there is a mixture of 2 p, 5 p, and 10 p coins.

How will we find the total value of this set? Hmm, I wonder? "I will put the coins of the same value together so they're easier to count," says Jacob.

So he puts the 2 pence coins together, the 5 pence coins together, and the 10 pence coins together.

That's a good idea, isn't it? "Then I will count the greater value coins first." So which are the greater value coins? That's right, the 10 pence coins have the greatest value.

We see 10 pence, but we think 10 pennies, so we count them in tens, don't we? Are you ready? 10, 20, 30.

40.

So we've got 40 pence there.

Now I will count on from 40 in fives.

So we know we've already got 40 pence, so let's use our 5 pences to count on.

45, 50, 55, 60, 65.

So so far we have 65 p.

So now I will count on from 65 in twos.

Hm, we have a strategy for counting on from odd numbers in twos, don't we? When I add 2 to an odd number, I will reach the next odd number, won't I? So 65 and 2 more will be 67, then 69, 71, 73, 75.

So there's 75 pence there altogether.

Sofia finds a different way to find the total value of the coins.

So she also counts the tens first and then adds on the five by counting on.

But then, after counting the fives, and knowing she has 65 pence, she notices that she has five 2 pence coins, which she knows is 10 p.

So 65 + 10 = 75 p.

So the total value of the coins is 75 p.

So now it's time to check your understanding again.

Collect a set of coins like this and find their total value.

Remember the strategies we've used to count more efficiently.

Okay, pause the video now while you try that.

Okay? And let's see how you got on.

So first we separate the coins by value, don't we? And count the greatest value coins first.

So what's the greatest value coin there? That's right, the 10 p coins have the greatest value.

10, 20, 30, 40, 50, 60.

So we've got 60 p there, and you may have already known that 6 tens would be 60.

Now we can count on from 60 in fives.

So we've got 60, 65, 70, 75, 80.

And then we have to count on in twos, don't we? So we're at 80, 82, 84, 86, 88.

So altogether there was 88 pence there.

Well done, if you did that.

There is 88 pence altogether.

Here are three purses or bags.

Which purse would you rather have? I think I'd like the one with the most money in, would you? Hmm, so which one will that be? Jun says, "I know without counting which bag has the most." I wonder how he knows.

Hmm, what's he thinking about to help himself, I wonder? "I will think about what's the same and what's different." That's a good idea, isn't it? So let's have a look what is the same in all of those bags? So Sofia notices that each bag contains a five p coin and a two p coin.

Hmm, so that's what's the same.

So now we can look at what's different to help us, can't we? So Sofia says, "I will look at the other coins in the bag to decide which has more." So we can see that that bag has two 2 p coins.

Then we've got two 5 p coins in the middle bag, and two 10 p coins in the third bag.

Hmm, so what do we know about the value of those coins? That's right, we know that 10 p is worth more than 5 p or 2 p.

So the two 10 p coins will have a higher value.

That bag must be worth the most.

It must have the most money.

Well done, if you spotted that.

So let's find out exactly how much each bag is worth.

So here's this first bag and we can see we've got three 2 p coins.

So that's equal to 6, isn't it? 6 p and then there is also a 5 p coin.

6 + 5 is a near double, so I know the total value is 11 p.

What about this second bag? So there are three 5 p coins, which is equal to 15 p, isn't it? 3 fives are 15, and there's also a 2 p coin.

15 + 2 = 17, so we know there's 17 p in the bag.

And let's have a look at this third bag now.

There are two 10 p coins, which is equal to 20 p.

There is also a 5 pence coin and a 2 pence coin.

So 20 + 5 + 2 = 27.

So I know there is 27 pence in the bag.

Okay, so now it's time to check your understanding again.

Which bag here contains more money? Remember to think about what is the same and what is different in each bag to help you.

So pause the video now while you try that.

So what did you think? Did you think it was B? Each bag has one 5 p coin and one 10 p coin, so we must look at the other coins.

So that's what's the same about them all, and if we look at the other coins, we can see A has a 2 pence, B has a 10 pence, and C has a 5 pence.

And we know that 10 p is worth more than 2 p or 5 p, so B must be the bag with the most money.

So well done, if you did that.

So here's the second part of this check.

So now find the total value of the coins in each bag.

So pause the video now while you try that.

Okay, and what did you think? Let's have a look.

In bag A, there is a 10 p, a 5 p, and a 2 p coin.

I know 10 + 5 = 15.

Then 15 + 2 = 17 p.

So bag A contains 17 p.

In bag B, there are two 10 p coins and a 5 p coin.

Two 10 p coins are equal to 20 p.

Then 20 p + 5 p = 25 pence, isn't it? So bag B contains 25 pence.

Then in bag C, there are two 5 p coins and a 10 p coin.

Two 5 p coins are equal to 10 p.

Then 10 p + 10 p = 20 p.

So bag C contains 20 p.

So well done, if you did that.

Here's the task for the second part of our lesson.

Find the value of each set of coins, counting coins of the same value together and starting with the greatest value coins first.

Remember to look for any patterns to help you.

You could use coins or draw the coins in a different order to help you as well, couldn't you? So there's A, B and C to work out there.

And then there's also another three sets here as well.

So pause the video now while you try that.

Let's see how you got on.

Did you do this? So let's have a look at set A.

We can see we've got two 10 p coins, they're the greatest value coins, so we put those first.

And then we've got the two 5 pence coins, and then we've got the 2 p coins there, haven't we? When we add them up, we've got 20 p, 10 p and 8 p.

You can count the coins of the same value by counting in tens or counting in fives or twos, couldn't you? Then when you add that up, 20 pence + 10 pence = 30 pence, and then 30 pence + 8 pence = 38 pence.

Then let's look at B.

So we put the same value coins together again, don't we? And then we've got 20 pence, 10 pence and 10 pence.

And 20 + 10 = 30, and 30 + 10 = 40 pence, isn't it? And then C, we've got 2 tens are 20, 2 fives are 10, and then we've got 6 twos are 12, haven't we? So 20 + 10 pence = 30 pence.

30 pence + 12 pence = 42 pence.

The number of 10 pence coins and 5 pence coins were the same in each case.

Did you notice that? That may have helped you.

But there was an extra 2 p each time, so each time the total value was 2 p more.

So if you spotted that pattern, instead of adding sets B and C, you may have realised that you just had to put an extra 2 pence on each time.

So well done, if you did notice that.

Now let's have a look at the next three sets.

So we'll put the like value coins, same value coins together.

And we've got 30 pence, 3 tens are 30 pence, and 3 fives are 15 pence and 3 twos are 6 pence.

30 p + 15 p = 45 p.

And then let's look at the next set.

So we've got 30 pence, 20 pence, 6 pence.

30 pence + 20 pence = 50 pence.

50 pence plus another 6 pence = 56 pence.

And then finally, we've got 30 pence, 25 pence, and 6 pence.

And when we put them together, 30 p + 25 p = 55 p.

55 p + 6 p = 61 p.

So well done, if you did that.

So did you spot any patterns there that could help you? If you thought about what was the same and what was different, you may have spotted in each case there is one extra 5 p coin.

So the total value increased by 5 p each time.

So well done, if you noticed that.

So now let's think about what we've learned in today's lesson.

Skip counting can be used to help you count coins of the same value.

When you have a set of coins of different values, you can count coins of the same value together, starting with coins of the greatest value first.

You can use what you know about the value of coins to help you compare sets of coins without calculating, can't you? To help you work more efficiently.

Okay, so well done.

I've really enjoyed today's lesson.

You've worked really hard and hopefully now you're feeling much more confident about counting and calculating with sets of coins and about comparing groups of coins in the most efficient way, so well done.
