Lesson video

Hi everyone, it's Mrs. Khaira and it's Lemony Lamb.

And look, it's a very special day today because it's Lemony's birthday.

He is turning five today.

Could you put your hands up if you are already five or will be turning five this year? Look at all those children! Lots of children turning five or are five already.

Fantastic! Well today we are going to be looking at continuing with our understanding of subtraction as take away.

Shall we begin? Great, let's go! Brilliant.

Well for today's lesson, you will need the following items. You will need a number track, which is available in today's lesson resources.

You will need some countable objects like cubes or counters or blocks, whatever you have to hand.

And then you will also need some real-world countable objects too.

So I've got some pencil crayons here but you can use whatever you have to hand.

So if you don't have these items ready, please press the pause button now, go and collect what you need, find a quiet space, and then press play when you're ready to resume.

Well done, everyone.

Let's have a look at our big picture for this unit.

Do you remember where it comes from? That's right, it's Mary Had A Little Lamb! From the nursery rhyme! Now I'm going to look really carefully at my big picture and I'm going to count something.

I'm going to give you a clue.

Let's see if you can help me figure out what it might be.

I have counted something in the picture and there are fewer than six.

So a smaller number than six.

Do you think you can have a guess as to what it is I'm counting? Well, if you said the yellow flowers on the screen, then you would be correct! There are one, two, three, four yellow flowers.

I'm going to represent those four flowers using my cubes.

How many cubes will I need? Let's see if I'm correct.

There's one, two, three, four cubes to represent my four yellow flowers.

Well done if you got that correct! Now I'm thinking about something else in the picture.

And I know there's only one of these objects.

What could I be counting? Hmm.

Well if you said the red scooter, then you would be correct.

There is one red scooter in the picture.

How would I represent that using my cubes? Hmm.

Well let's see if I'm correct.

Great! That's one cube to represent my one scooter.

Great work, everyone.

You have done amazing counting.

Right well let's have a look at a learning for today.

We're going to be practising take away using our number track to help us and some cubes to represent the numbers.

Lemony is here on-hand to give us some help.

So let's have a look at this question.

So first, Lemony has four candles to blow out on his cake.

Lucky Lemony! Then he blows out one of them.

Now, how many candles does Lemony still have to blow out? Well, let's use our number track and our cubes to help us.

So first there were four candles to blow out and there are my four cubes to show those four candles.

One, two, three, and four.

Then Lemony takes a big blow and blows out one of them.

So let's take one of those cubes away.

Now, let's see how many candles Lemony still has to blow out.

Well, I can see there are one, two, three cubes left on my number track.

That must mean, Lemony, that there are still three candles to blow out.

Great work! That means that four take away one is equal to three candles.

Great work, everyone.

Well done, Lemony! Let's have a look at one more example together.

Lucky Lemony, he's got eight cupcakes to eat all by himself.

Well it is his birthday.

So first, Lemony had eight cupcakes to eat.

Then he was feeling a little bit generous and he decided to share five of them with his friends.

So there are eight cubes on our number track to show our eight cupcakes and then Lemony wants to share five of them with his friends.

Now I wonder how many cupcakes Lemony has left afterwards.

So first there are eight cupcakes and there are eight cubes on the number track.

Then Lemony is going to share five of them so let's take five of those cubes away.

Can you help me? One, two, three, four, and five.

Brilliant.

Now, how many cupcakes do we have left over? Well, Lemony, do you agree? We can see that there are one, two, three cubes left on the number track.

That must mean, Lemony, that there are still three cupcakes left to eat.

That's because eight take away five is equal to three.

Fantastic, everyone! You've got the hang of this really quickly.

Well now it's your turn.

Lucky Lemony is having a big party and some of his family are going to be coming to join him.

Let's see how many of his family are in the picture.

We're looking at the sheep in the field.

Let's count together, using your careful counting finger.

We have one, two, three, four, five, six, seven.

So first, there were seven sheep in the field, on their way to Lemony's party.

Let's represent those seven sheep on to our number track using our cubes.

Have I done that correctly? Let's check.

One, two, three, four, five, six, and seven.

My seven cubes are in place.

Then some of those sheep find their way to Lemony's party.

So then three of those sheep manage to get to the party! Hooray! Now we want to work out how many sheep are left over.

How many sheep are left in the field.

So let's see.

Then three of those sheep make it to the party so I think we can take away three of our cubes.

Can you help me? One, two, three! Great work, everyone.

Then three of the sheep make it to the party.

Now how many sheep are left in the field? I wonder if you can help me find the answer.

Well I can see, Lemony, that there are one, two, three, four cubes left on the number track.

That must mean that there are four sheep still left in the field.

Great work, everybody.

Now what I'd like you to do is pause the video and I'd like you to use the talk task sheet, your number track, and your cubes to help you work out the answers to your very own take away first, then, and now stories.

Once you have completed the task, resume the video and we'll carry on with our learning.

Welcome back everyone.

Well for today's independent task, you are going to have a go at representing your very own first, then, and now take away stories using pictures to help you.

You are then going to check your answers using your number track and your cubes.

So let's have a look at this first question.

Lemony gets six presents for his birthday.

What a lucky lamb! Then he opens four of them.

Now, I wonder how many presents he has left to open.

So I'm going to use my pencil and I'm going to draw out my six present to begin with.

Are you ready to help me count? One, two, three, four, five, and six.

Thank you very much.

So there are Lemony's six presents.

First, Lemony had six presents.

Then he opened four of them.

So let's cross four of those pictures out to show Lemony has opened four of them.

Can you help me? One, two, three, and four.

Now, I wonder how many presents Lemony has got left to open for his birthday.

Well I know that I can use my number track and my cubes to help me find the answer.

So let's do this together now.

First, Lemony had six presents and there they are! One, two, three, four, five and six cubes to represent his six presents.

Then he opens four of them.

So let's take four of those cubes away.

Can you help me count? One, two, three, and four.

Great counting everybody.

Now how many presents does Lemony have left to open? Well I can see that Lemony has got one, two cubes left on the number track.

That must mean that he has got one and two presents left to open.

And that's correct! In my drawing, I can see I haven't crossed out two of the presents.

Great work, everyone! Now what I'd like you to do is press the pause button and I'd like you to have a go at representing your very own first, then and now stories using pictures to help you and then track your answer using your number track and your cubes.

Once you're done, you can resume the video and we'll finish off the last little bit of the lesson.

Welcome everyone.

Now in this final part of the lesson, we are going to play a true or a false game.

I'm going to tell you a first, then, and now story and I want you to tell me if you think the answer is true or false.

Let's have a look, shall we? So first, there were five children and they were playing musical statues at Lemony's party.

One, two, three, four, five children.

I'm going to represent them using five cubes on my number track.

One, two, three, four, and five.

Great! Then three of the children were out of the game.

I think we can remove three of those children.

Let's say goodbye to them.

One, two, and three.

And let's take away three of our cubes from the number track to show that three of those children are out of the game.

One, two, and three.

Now, there are three children left in the game.

Is that true or is that false? Can you show me that with your thumbs? Great work, everyone.

That's false.

Now there are two children playing the game.

I can see that there are two cubes on my number track and two children in the picture still playing the game.

That's because five take away three is equal to two.

Great work, everyone.

Now in lesson five of this unit, we will be continuing with using a number track to help us with our addition and our subtraction.

Lemony and I hope to see you there! It's bye from me and it's by from Lemony.
