Lesson video

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

In today's lesson, we will explain that a whole can be split up into parts.

So let's have a look at today's lesson outcome.

Here's the outcome of today's lesson.

I can explain that a whole can be split into two or more parts.

Here are the key words for today's lesson.

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

Your turn.

My turn, part.

Your turn.

My turn, split.

Your turn.

My turn, combine.

Your turn.

Well done.

You might have seen some of these keywords before.

Do you know what they mean? Let's look at the meanings of the words.

So we've got whole.

You could make a big circle with your hands to show that you have got a whole object, it means you've got all of it.

And then we've got part.

This is a piece of a whole object, so you might want to make a small part with your fingers to show that you've just got a piece of the whole.

Then we've got split.

You might want to make your hands go apart so that you are splitting a whole object into parts, or into pieces.

And then we've got combine.

That means that you're putting the pieces back together.

So you might want to bring your hands back together to show that you are putting those pieces back together to combine them to make the whole.

Well done.

Look out for those words in today's lesson.

Here's today's lesson outline.

So we will explain that a whole, a whole object can be split into parts, and we'll start off by splitting a whole into parts, and then we will be combining the parts to make the whole.

So let's have a look at the first part of the lesson.

Here are some children that will help us with today's lesson.

We've got Andeep and Izzy.

Let's start on the lesson.

Here is a whole carrot.

Can you see the whole carrot? I can see the stalk as well.

A whole can be represented by one object.

An object is whole when we have all of it.

Can you see all of the carrot? A whole can be split into two or more parts.

So here the carrot has been split into two parts.

Do the parts look the same? Not really.

Do they? These parts look different.

Izzy said the parts look different.

Are the parts smaller or larger than the whole.

That's right.

The parts are smaller than the whole.

The whole was much bigger, wasn't it? So a whole can be split into two or more parts.

The parts could look the same or different.

The parts could be different in size and shape.

The parts are smaller than the whole.

Here we've got an apple that has been split into two parts.

A whole can be split into two or more parts.

Do the parts look the same? Andeep thinks the parts look different.

Are the parts smaller or larger than the whole? That's right, the parts are smaller than the whole.

So this is what we've learned.

A whole can be split into two or more parts.

The parts could look the same or different.

The parts could be different in size and shape.

The parts are smaller than the whole.

Here's a pizza that's been split into parts.

Can you say the stem sentence with me? A whole can be split into two or more parts.

Do the parts look the same? Izzy thinks the parts look the same.

Are the parts smaller or larger than the whole? That's right, the parts are smaller than the whole.

Let's say our stem sentences together.

A whole can be split into two or more parts.

The parts could look the same or different.

The parts could be different in size and shape.

The parts are smaller than the whole.

Andeep and Izzy are cutting a banana.

What do you notice about the parts? Andeep said we have split the banana into two parts.

Izzy said the parts are about the same size.

What do you notice about the parts now? Andeep said the parts are a different size and shape.

Izzy said one part is big and one part is small.

Here is Andeep's part of of the banana.

Andeep said, "My part is smaller than the whole." Izzy said, "I have eaten my part." Is the banana still whole? No.

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

We can't see all of it anymore, can we? Let's check your understanding.

Andeep and Izzy are cutting a banana.

Who is right? Andeep said, "I can only cut the banana into two parts." Izzy said, "I could cut the banana into more than two parts." Who do you agree with? That's right, Izzy is correct.

We could cut the banana into more than two parts.

Here, Andeep and Izzy have cut a banana into three parts.

Andeep wants to know are the parts the same size and shape? Izzy thinks the parts look different.

Izzy said the parts are smaller than the whole.

Let's check your understanding.

Is this a whole or a part of a carrot? Pause the video and think about this one.

That's right, it is part of a carrot.

We can't see all of the carrot.

Some of it is missing.

Izzy said it is smaller than the whole.

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

Let's check your understanding again.

Is this a whole or a part? See if you can make the action for the right answer.

Pause the video and think.

That's right.

This one is a part of a banana.

Izzy said it is smaller than the whole.

We can't see all of the banana, can we? If some of the object is missing, it is not a whole, it's only a part.

Let's check your understanding again.

Is this a whole or a part of a carrot? Pause the video and see if you can do the right action.

That's right, this is a whole carrot.

Izzy said, "It is the whole carrot, because I can see all of it." An object is whole when we have all of it.

Let's check your understanding again.

Is this a whole or a part of a banana? Pause the video and see what you think.

That's right, it is the whole banana.

Izzy said, "It is the whole, because I can see all of it." An object is whole when we have all of it.

Here is a pizza.

Is this a whole or a part of a pizza? That's right, it is the whole pizza.

Andeep said, "It is the whole pizza because I can see all of it." An object is whole when we have all of it.

Is this a whole or a part of the pizza? That's right, it is a part of the pizza.

Andeep said, "It is smaller than the whole." If some of the object is missing, it is not a whole.

I think someone has eaten most of that pizza, haven't they? Which is bigger, the part or the whole? Have a look at the pictures.

We've got a part of a pizza and we've got a whole pizza.

Which one is bigger? That's right, the whole is bigger than the part.

The part is smaller than the whole.

Andeep said, "I could not eat the whole pizza." It must be too big.

Andeep said, "I will eat a part of the pizza." Let's check your understanding.

Which two pictures here show the whole carrot being split into two parts? Pause the video and think about this one.

That's right, the first two pictures showed the whole carrot being split into two parts.

It's been split into two parts in different ways, but it's still been split into two parts.

The other two pictures are not showing the whole carrot split into two parts.

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

Can you split the objects into parts? So we've got some pictures here of an orange, banana, apple, and pizza.

You could cut up the pictures, or you could draw your own, or you could use some real objects.

See if you can split the objects into parts, and think about these questions.

Are the parts the same? Are the parts bigger or smaller than the whole? And try with some other objects if you can.

Here's the second part of your task.

Split the wholes into parts in different ways.

Here we've got some bananas.

Can you try to split the bananas into parts in different ways? Here's some questions for you to have a think about.

Can you make parts that are the same? Can you make parts that are not the same? Can you make a part that is really big? Can you make a part that is bigger than the whole? How many ways can you do it? Try it with real fruit too.

If you've got some real bananas or some real fruit, you could try it with these.

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

Did you get on with your tasks? So first of all, I asked you to split the objects into parts.

So I have split the whole orange, and the whole banana, and the whole apple, and the whole pizza into different parts.

How did you split your objects, and did you try it with different objects? Are the parts the same or are they different? Are the parts bigger than or smaller than the whole? The parts are smaller than the whole, aren't they? Well done.

How did you get on with your bananas? You might have tried splitting the whole bananas in different ways.

Here are some ways that I tried.

You can make parts that are the same.

You can try to split the banana into two parts that look about the same size and shape.

You can make parts that are not the same.

You could have one part that's big and one part that's small.

You can make a part that is really big.

Did you try that? So you might end up with one really big part and one tiny part.

You cannot make a part that is bigger than the whole.

That's not possible, is it? There are lots of ways to do it.

How did you do it? Did you try it with real bananas as well? What would happen if you put the parts back together? That's right, you get the whole again.

Well done, everyone.

Let's move on to the second part of our lesson.

We'll be combining the parts to make a whole.

A whole can be split into parts in different ways.

Here's a whole pizza and we are going to split it into parts.

The parts may look the same or different.

Each part will be smaller than the whole.

The parts can be combined to make the whole.

That means they're put back together to make the whole.

Here's two parts of a pizza.

We are going to combine them to make the whole pizza.

It is a whole if we have all of it.

Izzy said, "If I eat both parts, will I eat the whole?" Yes, if she eats both of these parts of pizza, she will be eating the whole pizza.

A whole can be split into parts in different ways.

Here's another whole pizza.

We are going to split it into smaller parts.

Can you see I've got lots of parts now? The parts may look the same or different.

Each part will be smaller than the whole.

The parts can be combined to make the whole, so here I'm going to combine my parts, my pieces of pizza, to make them into the whole pizza.

So I've got my small parts and they're going to combine to make the whole pizza.

It is a whole if we have all of it.

Izzy wants to know if I eat all the parts, will I eat the whole? Yes, she will, won't she? Have a look at this part of a pizza? Could this be a whole? Andeep said, "This is my whole slice of pizza." It is a whole slice of pizza.

Sometimes a part can become a whole of something else.

Let's check your understanding.

Andeep and Izzy have parts of a banana.

Can you see their parts of the banana? Andeep said, "The parts will make a whole banana." Izzy said, "The parts will not make a whole banana." Who do you agree with? Pause the video and think about this one.

That's right, Andeep was correct.

The parts will make a whole banana.

Let's watch them being combined to make a whole banana.

There we go.

Now we've got a whole banana.

I can see all of it.

Let's check your understanding again.

Andeep and Izzy have parts of a pizza.

Andeep said the parts will make a whole pizza.

Izzy said the parts will not make a whole pizza.

Who do you agree with? Pause the video and think about this one.

That's right, Izzy was correct.

The parts will not make a whole pizza.

There are not enough parts here.

I think someone's eaten a piece.

Andeep and Izzy are cutting a banana.

Andeep said, "We have split the whole banana into two parts." Izzy said, "If I eat both parts, will I eat the whole?" Andeep said, "Yes.

If you eat both parts, you will eat the whole." Izzy wants to know, "Is the skin part of the whole banana?" Andeep said, "I think the skin is part of the whole banana, but we don't eat it." Do you agree? Let's check your understanding.

Andeep and Izzy have parts of a banana.

Andeep thinks the parts will make a whole banana.

Izzy thinks the parts will not make a whole banana.

Who do you agree with? Pause the video and think about this one.

That's right, Izzy was correct.

The parts will not make a whole banana.

They don't look right, do they? They don't look like they'll make a whole banana, do they? Let's check your understanding again.

Which parts here will combine to make the whole? I can see we've got some parts of an apple, a carrot, and a banana.

Can you match the parts that will combine to make the whole? Pause a video and think about this one.

How did you get on with this one? So you can match the two parts of the apple to make a whole apple, and you can match the two parts of the carrot to make a whole carrot, and you can match the two parts of the banana to make a whole banana.

How did you get on with that one? Here's a task for you to have a go at.

I've got some pictures of parts here.

We've got parts of a pizza, parts of a pineapple, parts of a carrot, and parts of an apple.

Can you combine the parts to make a whole? So you might want to cut out the pictures or draw your own and see if you can combine the parts to make a whole.

Here's the second part of your task.

Here, we've got a slice of cheese.

Can you split the whole piece of cheese into parts? So you might want to draw some lines and cut your slice of cheese into parts.

Then, can you combine the parts to make the whole piece of cheese? So 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 combine the parts to make the whole objects.

Did you combine the parts of pineapple to make a whole pineapple? And did you combine the parts of the carrot to make a whole carrot? And did you combine the parts of the apple to make a whole apple? And finally, did you combine the parts of the pizza to make a whole pizza? You can try this with real objects as well.

How did you get on on the second part of your task? I asked you to split the whole piece of cheese into parts and then combine the parts to make the whole piece of cheese.

You can see the parts that I've made and I've combined them to make the whole piece of cheese again.

How did you get on? We've got to the end of our lesson today.

Well done.

Today, we were explaining that a whole can be split into parts, and this is what we've learned.

A whole can be split into two or more parts in different ways.

The parts may look the same or different.

Each part will be smaller than the whole.

The parts can be combined to make the whole.

The whole will be bigger than the parts.

Well done, everyone.

See you next time.
