# Lesson video

In progress...

Hello everybody, it's Miss Sidhu here.

You might have met one of the new teachers this week, but we are all working together to do lots of fun Maths with you.

Now, today's a very exciting day because today we're going to be going to the Toy Shop.

Who's been to a Toy Shop before? What did you buy from the Toy Shop? We're going to be learning about the concept of change, and we're going to be buying some items from our Toy Shop and giving and receiving change.

Some of the items in our Toy Shop might even be my friend Humpty Dumpty, can we say hello to Humpty Dumpty? Or they might even be able to buy some Lego.

Who likes Lego, super.

Now, let's see what other things you might have.

In today's lesson, we are going to calculate the amount of change needed.

Now, this is Lesson Nine of the topic of Money.

Money, Money, Money.

You will need some paper and a pencil.

And there are times when you will have to pause the video to have a go at some of the activities yourself.

Now, let's get started.

Today we're going to look at our key vocabulary.

That means our star words.

Introducing the concept of change.

Independent task and answers, and finally a quiz to see everything that we have remembered.

Star Words! Star Words! Now, I know that we remember how we do our star words.

My turn first, then your turn.

Buy, sell, change pence, pounds, total, cost.

Super, and we're going to be using our Star Words in today's lesson.

Now, first we need to warm our brains up.

We've got a Brain Teaser here.

We have the number bonds of 10 represented, but we have some number equations, but the numbers are missing in some of these equations.

Can you help me find the missing numbers so that they add to 10? You can use your number bonds.

Number bonds, number bonds, who knows their number bonds.

Now, I want you to pause the video, have a think to remember your number bonds of 10.

And then I want you to explain your answers to the person next to you.

How did you get along with all of those number bonds of 10? Now, let's go through them together.

The first one, the missing number is five.

Five plus five is equal to 10.

Five and five, glad I'm alive.

The next one, four plus six is equal to 10.

Four and six are like tricks.

Three plus seven is equal to 10.

Three and seven, angels in heaven.

Two plus eight is equal to 10.

Two and eight, cake on a plate.

One plus nine is equal to 10.

One and nine, now I'm fine.

Now zero and 10 is equal to 10.

So zero plus 10 is equal to 10, zero and 10 my pet hen.

Now, how did you do? Who got them all correct? Can you shout it out if you've got it all correct? Super, give yourselves a pat on the back, well done.

Now, today is such a super exciting Maths lesson because we are going to the Toy Shop.

Now I'm going to choose a toy from the Toy Shop, but I only have a 10 pound to spend.

So I have 10 pound to spend.

Now, what things could we buy from the Toy Shop? Ooh, there's a trumpet, there's a Jack in the box.

Ooh, look at those shoes, I love those shoes or a football.

There's a kite and a windup car.

I wonder what we might choose.

But lots of those items have a tank and on those are the prices of the toys But all of them are different and none of them are the same as a 10 pound.

So when we do not have the exact amount to pay for an item, the shopkeeper gives us change.

The change is the amount of money leftover when the shopkeeper has taken away the value of the item.

The shopkeeper has extra notes and coins in the till for change.

Now, which one shall we buy today? Can everyone point to and shout to which item shall we buy today? Ooh, some of you said the kite.

I'm feeling very musical today.

I'm going to choose the trumpet.

I know lots of you were shouting at the trumpet as well.

I want you to listen really carefully to my Math story of when I went to the Toy Shop and I bought a trumpet.

Can everyone do the trumpets sound? Now, first I had a 10 pound note and then I bought a trumpet for three pound.

How much change will I need from the shopkeeper? So the shopkeeper will keep the 10 pound note, but they need to take away three pounds because that is how much the trumpet costs.

Now, the shopkeeper can't take away from the 10 pound note.

So they will have to exchange it for 10 pound coins and we've looked about exchanging coins this week.

So here we've exchanged a 10 pound note for ten one-pound coins.

Now, the shopkeeper must then give back the amount that is leftover once they've taken away the three pounds.

Now, how can we express this as an equation? So what can be the equation for our Math story? I want you all to have a think.

Can you shout it out? Okay, let's explore the equation under our Math story.

So, what is the whole? I know the whole has to be a 10 pound because we have a 10-pound note.

That's how much money we have.

And the other part is how much the item costs.

So the item costs how much? The trumpet costs, three pounds well done.

Now, I need to find out the other part.

I know I can use my number bonds of 10 to help me that we did in our Brain Teaser.

I know that seven and three make 10.

So I can use the number bonds that we practised rather than counting back in ones.

So the shopkeeper must give back seven pounds in change.

So 10 pound takeaway three pound is equal to seven pound.

So there's our seven pounds all made from one-pound coins.

Did you get the same as me? Wow, you're doing some super duper Maths today? I will definitely be taking you when I go to the shops.

We're back at the Toy Shop.

What shall we choose this time? We've already chosen a trumpet.

Now, can you point to the screen, what item shall we choose now? Shout it out.

Ooh, I heard somebody say a kite.

Ooh, I heard somebody say a car.

Ooh, lots of you said a football, I love football.

Do you like football too? Let's buy the football with a 10 pound note.

I think that you can help me this time.

Let's have a go at the Math story.

So first I have 10 pound.

Then I buy a football for five pound.

Now, how much change will I need from the shopkeeper? Remember, we had to exchange the 10-pound note for ten one-pound coins and think about the whole and the parts to fill in the equation.

I want you now to pause the video, have a think and then say your answer to the person next to you.

Remember thinking about the whole and the parts.

How did you do? What equation did you get? Okay, so first I have 10 pound and then I buy a football for five pounds.

How much change will I need from the shopkeeper? So, I know I need to exchange the 10-pound note for ten one-pound coins, and then I need to take away the amount for the football.

So I know the whole is 10 and I know one of the parts is the cost of the football, which is five pound.

Using my number bonds of 10.

Five and something makes 10.

What could the other part be? Can you shout it out? Super, the other part must be five as well.

So we need to do 10 takeaway five and the other part is five.

Did you get the same as me? Wow, super duper.

Let's give ourselves a double clap.

Well done, now let's see what we have now.

I know you're doing super, super Maths.

So I'm going to make it a little bit harder now.

This time instead of a 10-pound note, we are going to be shopping with a 20-pound note.

20 pound, aren't you very lucky.

We're going to be going to our Toy Shop.

What shall we choose at the Toy Shop first? Can you shout it out? Ooh, I heard lots of people saying a football, but we've already done a football.

This time, I heard somebody who said it the loudest a Jack in the box, let's buy a Jack in the box.

So, first I am going to have a 20-pound note.

So first I have a 20-pound note.

Then I buy a Jack in the box which costs six pound.

How much change will I get? So, as you can see, we need to exchange the 20-pound note for 20 one-pound coins and then take away the cost of the Jack in the box.

We need to write an equation for this Math story.

Remembering, we need to remove the six pounds because that's how much the Jack in the box costs.

And the rest of the money will be given back to the customer, to you, as change.

Now, you've got lots of information there to help you to do the equation now, have a think.

What could the equation be? Can you shout it out? Super, 20 pound take away or subtract, so 20 pounds subtract six pound is equal to 14 pound.

So the shopkeeper will give me 14 pounds.

Now, 14 pound, that's a lot of one-pound coins.

What notes or coins could the shopkeeper give back as change instead? Is there another way to give 14 pound as change? Everybody have a think.

So is there another way the shopkeeper could give 14 pounds as change? Can you shout it out? A little bit louder.

Super, lots of great ideas there.

I've chosen one of your ideas.

I heard lots of you say, instead of 14 pound in one-pound coins, you could give a 10-pound note and four one-pound coins.

And that is the same as 14 pound, super.

You have done some amazing Maths today and you've done some great counting.

Now, let's have a look what it is today.

Like we did before, we have 20 pounds to spend at the Toy Shop.

We need to find out the equations and write the whole and the parts to help us.

Then we need to write the change that we will get from the shopkeeper.

There might be an easier way to give back the change.

So here we've got the 20-pound note, take away five pound because the football cost five pound, which is equal to 15.

So the change, instead of 15 one-pound coins, the shopkeeper can give a 10-pound note and a five-pound note.

You can have a go with a Jack in the box and buying a kite that costs nine pound.

But then I've got a super challenge.

I know that all of you are super, super, clever and you are all ready for your super challenge.

Now, Karina started with 20 pound.

She bought two toys from the shop and she received nine pound change.

So which two items did she buy? So thinking about the whole and the parts.

So I'm thinking about which two items that she bought.

The Jack in the box.

Now, I bought that from the Toy Shop.

So how much has change would I get? Super, 14 pound change.

And the kite, how much change would I get? 11 pound, super.

What about the challenge? Did you get it correct? Remember the two parts are nine pound because that's how much change we got.

And then the other is 11 pound, which is the total cost of the two items. Karina could have bought a Jack in the box and a football, or she could have bought the lovely jubbly shoes and the trumpet.

Wow, you have done some super duper Maths today.

I hope you had fun at the Toy Shop.

Now I want you to complete your end of lesson quiz and I will see you tomorrow, bye.
