Hello, my name's Mrs. Cornwell and I'm going to be working with you today and we're going to be finding out all about money.
So I would imagine you already know quite a lot about money because we see it all around us every day, don't we? All different types of coins and notes.
So we're going to find out how we can use money in different ways.
We can use it to pay for items, we can add up how much money we've got.
And so the learning we do today is going to be really useful for us, isn't it? So I'm really looking forward to working with you.
I know you'll work really hard.
So let's get started.
So today's lesson is called calculate the total value of the coins in a set of 5 p coins.
And it comes from the unit unitizing and coin recognition: value of a set of coins.
So in our lesson today, we're going to skip counting fives and use that skip counting to find the value of a set of 5 p coins.
And hopefully that will help you when you are trying to find out how much money you have if you've got a set of five pence coins.
Okay, so let's get started.
So our keywords today are five pence coins.
My turn, five pence coins, your turn.
And value.
My turn, value, your turn.
And 5 p, my turn, 5 p, your turn.
And fives, my turn, fives, your turn.
Well done.
Excellent.
So in the first part of our lesson today, we're going to find the value of five pence coins using five-spot tokens, okay? And in this lesson, you'll meet Sofia and Jun and they're going to be learning about five pences with us as well.
So Jun and Sofia are counting some coins from their toy shop.
You can see them there, can't you? They sort the five pence coins and the one pence coins into two groups.
There's the five pence coins and there's the one pence coins.
Jun says, "I will count the one pence coins.
One pence, two pence, three pence, four pence, five pence." So Sofia says, "Well, I must have 5 p too." Jun says, "That can't be right." Let's think about why.
We know that each 5 p coin represents a group of five one pennies.
So a 5 p coin doesn't have the same value as a 1 p coin, does it? So we see 5 p, but we think 5 pennies.
Each coin can be represented by a five-spot token.
There we go.
The five-spot tokens remind us of each group of five pennies, don't they? I wonder how we could count the 5 p coins.
Do you have any ideas? We can count the 5 p coins in two ways.
One five penny, two five pennies, three five pennies, four 5 pennies, five five pennies.
There are five coins.
Each coin has a value of? That's right, 5 p.
That means we can also count in fives, doesn't it? When objects are in fives, we can count them.
Count them in fives.
5 p, 10 p, 15 p, 20 p, 25 p.
This is 25 p.
"The coins I had were worth 25 p," says Sofia.
Sofia finds some more five pence coins.
Let's find their total value.
"I will use the five-spot tokens to help me," she says.
One five penny, two five, pennies.
Three five pennies.
Four five pennies.
There are four coins.
Each coin has a value of 5 p.
That's right.
"That means I can count them in fives," she says.
5 p, 10 p, 15 p, 20 p.
This is 20 p.
Okay, so now it's time to check your understanding again.
Collect the five-spot tokens to help you count the groups of five pennies and then complete the stem sentences and find the total value of the coins shown.
All right, so you've got to decide whether the total value of that set is A, 6 p, B, 3 p, or C, 30 p.
So pause the video now while you try that.
Okay, and what did you think? Let's have a look.
So there's the five-spot tokens to represent the coins.
One five penny, two five pennies, three five 5 pennies, four five pennies, five five pennies, six five pennies.
So there are six coins.
Each coin has a value of? That's right, 5 p.
So this is? So we know we can count them in fives, don't we? 5 p, 10 p, 15 p, 20 p, 25 p, 30 p.
So it is 30 p.
So well done if you did that.
Each coin represents five pennies.
So we can count them in fives.
Jun counts these coins.
"This is 30 p," he says.
Do you agree? Hmm.
I wonder what you think about that.
Let's represent the coins with tokens to check.
So there we can see there's some five-spot tokens there.
But then Sofia says she's noticed something important.
Did you notice anything? Not all of the coins are 5 p coins.
So we can't count them all in fives, can we? The 1 p coins will need one-spot tokens and there they are.
Now we can count, can't we? 5 p, 10 p, 15 p, 20 p.
But then now we must count on it in ones.
21 p, 22 p.
So well done if you noticed that.
There is 22 p.
So now it's time to check your understanding again.
Which set of coins can you count completely in fives? Okay, so have a look.
There's three sets of coins there, okay? And remember to count completely in fives.
Think about what you will be looking for.
Okay? Pause the video now while you try that.
Okay, and let's have a look.
How did you get on? That's right.
Did you spot it? C.
To count the whole set in fives, every coin must be a 5 p coin.
So C was the only one where they were all five pence coins.
So well done if you spotted that.
Sofia wonders how she can check she has counted the coins accurately here.
She says, "I think this is 20 p." Jun has an idea.
"You could count back to the start." Let's check.
5 p, 10 p, 15 p, 20 p, 20 p, 15 p, 10 p, 5 p.
And there's Sofia saying, "I was right!" She knows she was right.
She counted accurately because she got back to the start, didn't she? Back to the number where she started.
So now it's time for another check.
Collect the five-spot tokens to represent the five pence coins and count them, then count back to the start to check you counted them accurately.
So you're counting the total value of the set, aren't you? So pause the video now while you do that.
So first of all, you need to collect the tokens, don't you, for the five-spot tokens to represent the coins.
Then you need to count them in fives, 5 p, 10 p, 15 p, 20 p, 25 p, 30 p, 35 p, 40 p.
And then we need to count backwards to check we counted accurately.
40 p, 35 p, 30 p, 25 p, 20 p, 15 p, 10 p, 5 p.
So well done if you did that.
So now here's the task for the first part of our lesson.
Use real coins to make each card.
Make sure you use the same coins that are on the card.
Then tick each card that can be counted completely in fives.
So draw the five-spot tokens for the cards you ticked and find their total value.
Remember to count backwards to check you were right.
That's really important to check that you counted accurately.
So pause the video now while you try that.
And let's see how we got on with that then.
So we're looking for sets that can be counted completely in fives.
So those sets will have to be made up of completely of 5 p coins, won't they? So is A only made of five pence coins? No, we can see some 2 p coins there.
So A can't be counted completely in fives.
What about B? Yep, B is made up of just five pence coins.
So you can count that in fives.
What about C? Yep, C also you could, couldn't you? What about D? That's 10 pence coins.
So it would be more efficient to count those in tens, wouldn't it? What about E? Again, that's got a mixture of fives and tens, so you wouldn't count it completely in fives, would you? And what about F? That's right, that's also made completely of fives.
So you would count that in fives.
So well done if you spotted that.
Each of these sets had only five pence coins, so they could be counted completely in fives.
And let's look at how we would draw the tokens for those sets.
So if you look at this first set B, you can see that there are seven five pence coins.
So you would need to draw seven tokens.
And we just write a five in the middle because it takes a long time to draw five, the five spots, doesn't it, in each token.
And then we can count in fives to find the total value.
5 p, 10 p, 15 p, 20 p, 25 p, 30 p, 35 p.
And then we can count backwards to check that we counted accurately so that we know it was 35 p.
And now let's check we were right.
35 p, 30 p, 25 p, 20 p, 15 p, 10 p, 5 p.
So we were right, weren't we? Well done.
Okay, and then let's look at C.
So we've got eight five pence coins there, haven't we? So we need to draw eight tokens and then count them in fives.
5 p, 10 p, 15 p, 20 p, 25 p, 30 p, 35 p, 40 p.
Okay, and then we need to count backwards to check, don't we? So we need 40 p, 35 p, 30 p, 25 p, 20 p, 15 p, 10 p, 5 p.
So we know we were accurate, so well done.
And then we can see we've got five 5 p coins at the bottom here, haven't we? So we need five tokens and then we say 5 p, 10 p, 15 p, 20 p, 25 p, and then count backwards to check, 25 p, 20 p, 15 p, 10 p, 5 p.
Well done.
Excellent work.
So the second part of our lesson is where we're going to find the value of a set of 5 p coins.
So let's see what we're going to do with this.
Jun wants to find out the total value of the coins in his pocket, but this time, he has no tokens to help him.
Hmm, but there's Sofia and she's saying, "I don't think we need them." Let's think about what we know about each coin to help us.
What is the value of each coin? One five pence coin, two five pence coins.
Three five pence coins.
There are three coins.
Each coin has a value of 5 p.
That's right.
We know when pennies are in groups of five, we can count them in fives.
5 p, 10 p, 15 p.
This is 15 p.
"The coins in my pocket are worth 15 p," says Jun.
The children put their coins together.
What is the total value of their coins now? So there are nine coins, aren't there? Each coin has a value of 5 p.
Now, each 5 p represents five pennies.
So that means we can count them in fives, can't we? So we can say 5 p, 10 p, 15 p, 20 p, 25 p, 30 p, 35 p, 40 p, 45 p.
This is 45 p.
Okay, so now it's time to check your understanding again.
Complete the stem sentences, then find the total value of the coin shown.
So the stem sentence is there to help you.
So you've got to decide if it's 35 p, 25 p or 20 p.
Pause the video now while you do that.
Five coins.
That's right.
Okay, each coin has a value of 5 p.
So this is 25 p.
Let's just check.
5 p, 10 p, 15 p, 20 p, 25 p.
So well done.
Each 5 p coin represents a group of five pennies.
So I can count them in fives.
Jun and Sofia each emptied their piggy banks.
Who has more money? Hmm, I wonder.
Sofia says, "I will move the coins into a line to help me count" 'cause it's quite tricky to compare them like that, isn't it? So she puts them both into a line.
"Each coin is worth 5 p.
So I will count them in fives," she says.
5 p, 10 p, 15 p, 20 p, 25 p, 30 p, 35 p.
So she had 35 p and then 5 p, 10 p, 15 p, 20 p, 25 p.
So Sofia says, "I have 35 p and Jun has 25 p, so I have more money." But Jun says, "I knew that, I didn't need to count." I wonder how he knew.
Did you spot anything that could help? That's right, every coin has the same value, and when lined up, we can see Sofia has more coins than Jun, so she must have more money.
So now it's time to check your understanding again.
Here are Jun's 5 p coins.
Tick the set that is worth less than Jun's coins.
Pause the video now while you have a think about that.
Okay, and then let's see what you thought.
Did you get it, C? You can see that Jun has five five pence coins, and we know that C has four five pence coins.
And so that must be worth less than Jun's coins, mustn't it? So well done if you spotted that.
Sofia knows there are nine five pence coins left in the till.
She wants to know how much money that is.
"I can't see the coins.
How can I find their value?" she says.
Jun says, "I have an idea.
We could represent each five pence coin as a step of five on a number line." Oh, that is a good idea, isn't it? So there's a number line, and we know there are nine coins, aren't there? Each coin has a value of 5 p.
So we need to do nine steps, don't we, representing the nine coins.
And each step is worth five.
Each step represents five pennies.
So I can count them in fives.
5 p, 10 p, 15 p, 20 p, 25 p, 30 p, 35 p, 40 p, 45 p.
So she has 45 p.
There's 45 p in the till.
Perhaps you could use that strategy to work out the value of some of other sets of five pence coins.
So now let's check your understanding of that.
Use the stem sentences to help you draw the steps on the number line and find their total value.
And Jun has given us a clue there to help us, isn't he? He's saying, "I have four five pence coins in my pocket." So pause the video now while you try that.
Okay, and let's see how you got on.
So there are four coins.
Each coin has a value of 5 p.
So let's see what that is.
So we need one, two, three, four steps on our number line to represent the four coins.
And each step has to be worth five, doesn't it? 'Cause they're five pence coins.
And now we can count in fives.
5 p, 10 p, 15 p, 20 p.
So this is 20 p.
He must have 20 p in his pocket.
Jun has hidden some five pence coins in a bag.
He has eight coins.
Sofia tries to find their total value.
"I have an idea we could draw the coin," says Jun.
"It will take me a long time to draw the coins.
I have a different idea," say Sofia.
"I'll use my fingers to represent each group that I count.
There are eight five pence coins, so I will put up eight fingers." Each finger's going to represent a coin, isn't it? So there's the eight fingers, there are eight coins.
Each coin has a value of 5 p.
So we're going to count them in fives.
And then we'll know how much the total value is.
5, 10, 15, 20, 25, 30, 35, 40.
So this is 40 p.
So that was a good strategy to use.
Very useful, wasn't it, if you can't see the coins.
So now let's check your understanding of that, counting fives on your fingers to find the total value of Sofia's coins.
Okay, there's some stem sentences there to help you.
And here's Sofia's clue.
She's telling you, "I have five pence coins." So count on your fingers to find out the total value of her six five pence coins.
Pause the video now while you try that.
So there are six coins.
Each coin has a value of 5 p.
Sofia's told us that.
So we need to find out the total value.
So she's put five fingers up first and she counts in fives.
5, 10, 15, 20, 25.
But then we know that she's got six five pence coins.
So she needs another finger, doesn't she? So she needs to put up six fingers.
So she counts on another five from her 25, and that will be 30.
So this is 30 pence.
So well done if you did that.
So here's a task for the second part of our lesson.
Play a game with a partner.
You will need a set of 10 five pence coins.
"I will pick up a handful of coins from our set and tell you how many coins I have," says Jun.
And then Sofia will skip count on her fingers in fives to find the total value of Jun's coins.
"I will count my coins in fives," says Jun "to see if you were right." And then we will both draw the coins and write their total value to prove we were right.
Okay, so pause the video now while you have a try at that.
And here's the second part of our task.
here is a bag of 5 p coins.
Jun and Sofia both look in the bag, and they give us some clues to help us work out how many coins are in the bag.
Jun says, "There are fewer than 10 coins in the bag." Sofia says, "There are more than five coins in the bag." How much money could be in the bag? And then think about working systematically in an order to find all the different possibilities so now know you've found them all.
And then draw the coins to show the amounts and find their total value.
Pause the video now while you have a try at that.
So let's see how you got on with the first part of our task.
You may have done this.
I have five coins.
So Jun must have picked up five coins out of the set.
And so Sofia puts up five fingers and skip counts in five, using one finger for each number counted.
So there they are.
And then she goes, 5, 10, 15, 20, 25.
"And then the total value of your coins is 25 p," she says.
So she draws the tokens to represent 25 p, the five tokens.
So well done if you did that.
Now, the second part of our task, you may have done this.
So we know there were fewer than 10 coins in the bag, but more than five.
So Sofia is working systematically.
She says, "I will think about which numbers are between five and 10.
Six is between five and 10.
There could be six coins." So she draws her six coins.
"So there could be 30 p in the bag," says Jun.
5 p, 10 p, 15 p, 20 p, 25 p, 30 p.
Then Sofia tries seven, doesn't she? Seven is between five and 10.
There could be seven coins.
And she draws her seven coins.
And Jun says, "Five more than 30 p is 35 p, so there could be 35 p in the bag." Did you notice what Jun did there? He used a very efficient strategy, didn't he? Instead of counting in fives again from the start, he realised that there was just one extra 5 p.
So he just counted five pence more from 30, didn't he? So that was a very good strategy to use.
Okay, and then Sofia's thinking she's tried six coins, seven coins.
So now she's going to try eight coins.
Eight is between five and 10.
There could be eight coins and she draws them.
Oh, I wonder what strategy Jun will use to work out the total value of those eight coins.
That's right.
Five more than 35 p is 40 p.
So there could be 40 p in the bag.
I wonder how many coins Sofia will try now.
So she's tried six coins, seven coins, eight coins.
That's right, she tries nine coins, doesn't she? Nine is between five and 10.
So there could be nine coins and she draws them.
And then can you predict what the total value of those nine five pence coins will be? That's right.
Five more than 40 p is 45 p.
There could be 45 p in the bag.
So well done if you did that.
Excellent work.
You've worked really hard in today's lesson and hopefully you've found out lots about using five pence coins.
And also, you've found some efficient strategies you can use to help you when you're working.
So well done.
So now let's think about what we've learned in today's lesson.
We can use five-spot tokens to remind us that a 5 p coin has the same value as 5 pennies.
We can skip counting fives to find the total value of a set of 5 p coins.
We can check we have counted accurately by counting backwards.
We can only skip counting fives if all the coins in the set are 5 p coins.
So well done.
Excellent.
You've worked really hard in our lesson and I've really enjoyed finding out all about money and 5 p coins with you.
And perhaps the next time you go to the shop, you'll be able to help count some of the money.
