Lesson video

Hello, I'm Mrs Cayley and I'm going to help you with your learning today.

We're going to be explaining what a whole is.

Here's the lesson outcome for today.

So by the end of the lesson you'll be able to do this.

I can explain what a whole is and what it is not.

Here are our keywords for today's lesson.

Can you say them after me? My turn, whole.

Your turn.

My turn, all of it.

Your turn.

My turn, not whole.

Your turn.

My turn, part.

Your turn.

Well done.

We'll be using these keywords in today's lesson.

You might have seen some of them before.

Let's check the meanings.

So the first one is whole.

Now this doesn't mean a hole in the ground, it means something different.

So when we say this whole, I'm going to make a circle with my hands around an imaginary object.

Can you try that and can you say whole? Whole.

And that means that we have got the whole object, we've got all of it.

Then we've got not whole.

So I'm going to make a cross.

We've not got the whole object because we have not got all of it.

Then we've got part.

This means we've got a small piece of the whole, but we have not got all of the whole.

So look out for those words in today's lesson.

Here's the lesson outline for today's lesson.

We will be explaining what a whole is and we'll start off my looking at a whole and then we will look at not whole.

Here are some children that are going to help us in today's lesson.

We've got Lucas and Jun.

Here are some objects.

What do you notice? What can you say about the objects? Lucas said, I can see one apple.

Jun said, I can see one carrot.

What did you notice about the objects? Lucas and Jun are wondering what a whole is.

Can you help them? Lucas has got a whole apple.

Jun has got a whole carrot.

Can you see them there? Lucas said, this is a whole apple because I have all of it.

Jun said, this is a whole carrot because I have all of it.

Do you agree? A whole can be represented by one object.

An object is whole when we have all of it.

Let's check your understanding.

Is this a whole apple? What makes this a whole? Why is it a whole apple? Is the stalk part of the whole apple? Can you find anything else that is a whole? So pause the video and think about these questions.

What did you think about the apple? Do you think it's a whole apple? I think it is.

It doesn't look like there's any parts missing.

It looks like we've got all of it.

So what makes this a whole? Have we got all of it? Why is it a whole apple? We've got all of it, haven't we? Is the stalk part of the whole apple? I think it is, but some apples don't have a stalk, do they? Can you find anything else that is a whole? Have a look around you.

Can you see anything that's a whole? You might have a whole pencil.

You might have a whole piece of fruit.

You might have a whole packet of sweets.

You might have a whole class of children with you.

What have you got that's a whole? What do you notice here? We've got two bananas.

Lucas wants to know, are these whole bananas? I can see we've got one small banana and one bigger banana.

Are they both whole bananas? Yes they are.

Wholes can be different sizes.

It doesn't matter if it's big or small, it can still be a whole.

What do you notice here? We've got some different sized carrots, haven't we? Are they all whole carrots? What is the same about them? And what is different? Is the small carrot a whole carrot? And how do you know? Yes, it is.

Wholes can be different sizes.

Jun said they are all whole carrots.

Let's check your understanding.

Who do you agree with? Lucas said, we both have a whole banana.

Jun said, my banana is small so it is not a whole banana.

Have a look at their bananas and who do you agree with? That's right, Lucas was correct, we both have a whole banana.

Even though Jun has got a small banana, it's still a whole banana.

Let's check your understanding.

Which images here are showing a whole pizza? So look at the three pictures and decide which ones are showing a whole pizza.

Pause the video and think about this one.

What did you think about the pizzas? I think the first one is showing a whole pizza because I can see all of it.

What about the second picture? Yes, that's also showing a whole pizza.

I can see all of it still, even though it's been cut up into slices.

What about the last picture, is that showing a whole pizza? No, that's just part of a pizza, isn't it? Some of it has gone.

I cannot see all of it.

An object is whole when we have all of it.

Let's check your understanding again.

Which images here are showing a whole cake? Pause the video and think about this one.

What did you think about this one? Which images were showing a whole cake? The first picture is showing a whole cake because I can see all of it.

The second picture is not showing a whole cake.

I can only see one slice of cake there, that's just part of the cake.

The last picture is showing a whole cake, it's got some candles on this time.

I can see all of the cake.

An object is whole when we have all of it.

Lucas is asking a question.

Are the candles part of the cake? Do you think they're part of the whole cake? Some cakes have candles on, don't they? So it might be part of the whole cake.

Here's a task for you to have a go at.

Can you have a look around you and find some objects that are whole? And think about, what do you notice? Are they the same or are they different? You might want to draw some pictures or take some photos of your whole objects, or make a collection of them.

Here's a stem sentence to help you talk about your objects.

Can you try to use the stem sentence to tell someone why you think this is a whole object? So the stem sentence says this is a whole something because and think about how you know it's a whole object.

So pause the video and have a go at your task.

How did you get on with your task? I asked you to find some objects that are whole.

You might've found some objects like I did.

Did you use the stem sentence to help you? So the first object I found was a carrot and I said this is a whole carrot because I have all of it.

Then I found a tomato and I said this is a whole tomato because I have all of it.

Then I found an egg and I said this is a whole egg because I have all of it.

Then I found a pencil, this a whole pencil because I have all of it.

Then I found a balloon, this is a whole balloon because I have all of it.

Then I found an apple, this is a whole apple because I have all of it.

And I found a pizza, this is a whole pizza because I have all of it.

Finally, I found a ball, this is a whole ball because I have all of it.

What objects did you find? Are they all the same size? Or did you have some big wholes and some small wholes? Well done, let's have a look at the second part of the lesson where we'll be thinking about not whole.

Lucas has cut his apple.

Jun has cut his carrot.

Do you think they're still whole objects? Lucas said this is not a whole apple because I do not have all of it.

Jun said this is not a whole carrot because I do not have all of it.

Do you agree? If some of the object is missing, it is not a whole.

Who has a whole apple? Is it Lucas or Jun? That's right, it's Jun.

This is a whole apple because I have all of it.

Lucas said this is not a whole apple because I do not have all of it.

An object is whole when we have all of it.

Who has a whole carrot? Is it Lucas or Jun? Have a look at their carrots.

That's right, it's Lucas.

Lucas said this is a whole carrot because I have all of it.

Jun said this is not a whole carrot because I do not have all of it.

An object is whole when we have all of it.

Let's check your understanding.

Is this whole or not whole? Look at the picture.

That's right, this one was a whole pizza.

An object is whole when we have all of it.

Let's check your understanding again.

Is this one whole or not whole? Pause the video and think about this one.

That's right, this one was not whole.

This is not a whole pizza.

If some of the object is missing, it is not a whole.

I think someone has eaten some of this pizza.

Let's check your understanding again.

Is this pineapple a whole or not whole? Pause the video and think about this one.

That's right, this is a whole pineapple.

An object is whole when we have all of it.

Let's check your understanding again.

Is this lemon a whole or not whole? Pause the video and think about this one.

That's right, this one is not a whole lemon.

If some of the object is missing, it is not a whole.

Let's check your understanding again.

Is this lemon whole or not whole? Pause the video and have a look at this one.

That's right, this is a whole lemon.

An object is whole when we have all of it.

Let's check your understanding here.

Which images show a whole apple? Pause the video and see if you can find the ones that are showing a whole apple.

I can see some whole apples here.

Can you? We've got one, two, three whole apples.

Some of them are big and some of them are small, but they are still whole apples.

Wholes can be different sizes.

Let's check your understanding again.

Which images show a whole carrot? Pause the video and see how many whole carrots you can find.

Did you find some whole carrots? I can see we've got one, two, three whole carrots.

Some of them are big and some of them are small, but they're still a whole carrot.

Wholes can be different sizes.

Here's task for you to have a go at.

Can you cut up some pizza slices to make a whole pizza? So there are some pizza slices here that you could cut up or you could draw your own and see if you can put them back together to make a whole pizza.

And think about, how do you know if it's a whole pizza or not? Here's the second part of your task.

Can you sort the cards into whole or not whole? So you can see some pictures here, pizzas, lemons, and carrots.

Some of them are whole and some of them are not whole.

So see if you can put them in the right place and think about, how do you know? Pause the video and have a go at your tasks.

How did you get on with your tasks? So first of all we asked you to make a whole pizza from the pizza slices.

So here are some ways that I've put the pizza slices together to make a whole pizza.

How did you cut up your pizzas? And how did you make the whole pizzas? And how can you check that they are a whole pizza? Hopefully you remember our stem sentence, we know it's a whole pizza because we have got all of it.

Lucas wants to know, if I ate a slice, would it still be whole? No, it would not be whole, would it? If he ate a slice, it would not be a whole pizza because he would not have all of it.

How did you get on in the second part of your task? We asked you to find the objects that were whole and the objects that were not whole.

I found a whole carrot, a whole lemon, and a whole pizza.

And I know it's a whole because I can see we have all of it.

Then I found a not whole piece of carrot, a piece of lemon, and a piece of pizza, and I can see that they are not whole because we have not got all of it.

How did you get on? Perhaps you can find your own objects that are whole and not whole and add them to your collection.

We've got to the end of our lesson, well done everyone.

Today we were explaining what a whole is and this is what we've learnt.

A whole can be represented by one object.

An object is whole when we have all of it.

If some of the object is missing, it is not a whole.

Wholes can be different sizes.

Well done everyone.
