Lesson video

In progress...


Hello, everybody.

I'm back again for some more exciting learning.

And of course, I've got Hedwig with me my wonderful talk partner.

Hopefully she won't fall asleep as much during this lesson but I'm sure we can help her at the end if not.

Now, before we start our lesson I wanted to share some exciting news with you.

Look what I managed to grow in my garden.

This is a strawberry and I managed to grow it all by myself.

And I'm very, very proud of myself.

Sadly, there's only one because the slugs ate the rest of them.

But I suppose it's nice to share, isn't it? Even if it is with slugs.

Have you done anything this week that you've been really proud of as well? Maybe you could tell the person in your room or your talk partner, or you could shout it at the screen to let me know what you've done.

Let me hear you all.

I bet you've done some wonderful things.

Now, are you ready to get started with our maths? Today we are going to find the total cost of two items. This is lesson eight in the topic of money and you're going to need some paper and a pencil.

And there will be times when you need to pause the video so that you can have a go at the activities yourself.

First, we'll go through our key vocabulary.

And you're going to need to use your knowledge of coins to identify them to find the total.

You're going to need you to use your knowledge of addition and subtraction using money just like we have done the past two days.

And then you're going to do an independent task and check the answers.

And then a final quiz to see what you have learned at the end.

Let's check our Star Words together.

These are the words you're going to need to be able to complete the lesson.

Hands up, Star Words! Let's punch them out.

Buy! Sell! Altogether! Pence! Pounds! Total! Cost! I wonder how many times you'll use those words throughout this lesson.

Let's start off with our brain teaser to get ourselves warmed up.

What I want to know is which of these items is the most expensive to buy and how do you know? So look very carefully at the items. Which one is the most expensive? Pause the screen and have a go.

Did you identify it? I think that the comic is the most expensive and I use my knowledge of tens and ones to help me figure out why.

So I can see that if I split that 54 pence up into tens and ones, I've got five tens and four ones.

Now, there's nothing else in that list that has as many as five tens so the comic book must cost the most.

We are back at the market.

Now, has anyone ever been to the market or to a shop and they have bought more than one item while they've been there? I certainly have.

Today that's exactly what we're going to be doing.

We're going to go shopping to buy more than one item.

We're going to buy two items and we're going to add together the cost to find out how much it costs us altogether.

The exciting thing is that we visit Fairyland Market.

Look at this long list of things here that we could buy.

And you can choose anything you want from this list later in the lesson to be able to buy and then add up how much it costs.


I'm going to start off.

I can see that I've a whole long list of things but I want to buy the cake and then the apple because then I've got something healthy to go with my cake as well.

So I'm going to look very, very carefully to see how much these items cost so that I can find the total amount of the two of them together.

So if you look carefully, you can see that the cake all the way along that dotted line, costs 40 pence.

So that's one of my parts that I put in my whole-part model.

And the apple costs 20 pence.

So I've got the items individually.

Now I need to add those together to find the total cost of those items. I know that four plus two is equal to six.

So 40 plus 20 must be equal to 60.

Let's check that on the place value.

I've got my ones and I've got the tens.

So 40 pence is four tens and zero ones.

20 pence is two tens and zero ones.

Zero plus zero is equal to zero.

Four plus two is equal to six.

I was right.

It's 60 pence.

The whole is 60, the parts are 40 and 20.

Now, I know that my items cost 60 pence but which coins can I use to pay for it? That's the tricky bit.

Let me look at all my coins again and see if I recognise them.

I've got a one pence, a two pence, a five pence, a 10 pence a 20 pence, a 50 pence, and a one pound.

Now my items cost 60 pence all together.

What I want you to do is look very carefully at the choices of coins there and work out which coins you could use to equal 60 pence.

I'll give you a clue.

There's more than one way of doing it.

Pause the screen now, and see if you can have a go.

Did you find all the same answers that I did? So I could have 50 pence and 10 pence.

Five plus one is equal to six, so 50 plus 10 is equal to 60.

You could have had 20 pence, 20 pence, and 20 pence.

Two plus two plus two is six, so 20 plus 20 plus 20 is 60.

You could have had the option in the purple box.

I'm going to start off adding with the biggest number because remember I told you yesterday it's much easier to start counting with the biggest number.

So I can see that I've got a 20 pence and another 20 pence.

So two plus two is four, 20 plus 20 is 40.

So that's 40 pence.

Add my 10 pence is 50.

50 add five is 55, and then add another five is 60.

So that's another way to get to 60 pence.

And the final way over there in the corner in the green box I've got a 50 pence coin and then.

I bet you could roll your twos with me actually.

So I've got 50, 52, 54, 56, 58, 60.

So we found another way to make 60.

Can you see all of those options? It doesn't matter if you didn't get them all.

Have a look at them now and see if you can figure out how they all add up to 60.

Now it's your turn.

You can choose whatever is that you want to buy during your independent task from the Fairyland Market store.

Your job is to find out how many different pairs of items you can find to find the total cost.

So I chose originally to buy the cake and the apple and we added up the 40 pence and the 20 pence and then we worked out which coins we could use to make 60 pence.

But you might like to choose something different.

For example.

Hmm, I rather fancy a chocolate biscuit.

Do you fancy a chocolate biscuit as well? Me.

Maybe you fancy something else.

What else would you like? Oh, some of you are going for another apple.

Some of you want the sandwich.

Some of you want a banana.

Well, I'm going to try with the chocolate biscuit and the milk because I like chocolate biscuits and milk together.

So what I need to do is find how much each of those items costs for a start.

I can see that the milk costs 40 pence and the chocolate biscuit costs 10 pence.

Four plus one is equal to five so 40 plus 10 is equal to 50.

Now I need to think really carefully.

My items cost 50 pence altogether.

Which coins could I use to make 50 pence? Well luckily, there is a 50 pence coin.

So if I have one of those, I could just use 50 pence.

Some of you might like to challenge yourself and see if you can figure out other ways of making 50 pence using different coins.

Now, there is a task sheet here to help you with all of the different coins on, to support you in it.

There's also a whole-part model for you to use to try and find the parts and the whole.

Remember to put each of the costs of your items in the parts and add them up to find the hole.

If you need a little bit of extra help there are some addition equation boxes already written out for you that you could use to add your totals together.

Pause the video now and see how many different ways you can find of adding up those two items. How did you get on? Did you manage to find lots of different combinations? I bet you bought lots of things from the Fairytown Market store today.

I had a really, really lovely time adding those items up with you.

Sadly, Hedwig fell fast asleep again.

Should we wake her up? Everybody quickly, say, "Wake up Hedwig! Wake up!" Oh, she's a bit grumpy after being asleep.

Shall we explain to Hedwig what we learned today because she slept through the lesson? Have a little think.

See if you can tell your talk partner what you learned today.


Now, today I used my knowledge of coins, the value of coins to be able to figure out which ones I needed to buy certain items. I also decided to buy two items at any one time today.

So I needed to use my knowledge of number bonds and addition to add those two items together to find the total.

Does that make sense, Hedwig? I think it does.

I wonder what Hedwig would have chosen if she'd gone shopping at Fairyland Market store today.

See you all again very soon.
