Hello.

My name is Miss Jones.

And I'm going to to be teaching you Math today.

I'm going to start the lesson with a quick joke.

Are you ready? If I had six oranges in one hand and seven apples in the other, what would I have? Go on tell me, by whispering into the screen.

If I tell you, remember it's joke.

Six oranges in one hand, seven apples in the other, I would have big hands.

Let's start today's lesson.

Today we're going be comparing and ordering millilitres and litres.

Here's the lesson agenda.

We start with the new learning, where we look at how many millilitres there are in litres before we order them.

Then there will be a talk task, followed by an independent task, and then finishing off with a post-quiz.

You will need a pencil and some paper for this lesson.

Please pause the video now and collect these items if you haven't done so already.

Let's start with our learning.

How many mililitres are there in one litre? I'm going to pause to give you time to think.

Do you know? Can you say it to the screen? Tell me now.

Well-done.

There are 1000 millilitres in one litre.

1000 millilitres is equal to one litre.

How many millilitres are in there in half a litre? If I know there are 1000 millime.

millilitres in one litre, then how many will there be in half? I'm going to pause again to give you time to think.

Do you know? Tell the screen.

Well-done.

There are 500 millilitres in half a litre.

These are key facts that we will need later on in today's lesson.

Now let's look at doubling amounts.

Here you'll see the hundreds have been doubled.

Can you double the blue dienes? How do you know? I'm going to pause to give you time to think.

Go on.

Tell the screen.

Can you double the blue glu.

blue dienes? How do you know? Great job.

I can double the blue dienes.

When we double, it means twice as much, so I have twice as many blue dienes.

So I started with three, and now I have six.

Now let's look at halving.

Here is a clue with the stars to help you.

Can you halve the blue dienes below? How do you know? I'm going to pause to give you time to think.

are you ready? Tell the screen.

Great job.

You can halve the blue dienes by sharing them into two groups.

When we halve, half means one of two equals parts of a whole.

Now it's time for your talk task.

For you talk task today, you're going to match the cards.

The blue cards match with the read cards.

Blue is half the red card or red is double the blue card.

As you do it, say these sentences out loud.

I have.

Double this is.

I have.

Half of this is.

I'll show you the first example.

I have 100 millilitres.

Double this is 200 millilitres.

I have 200 millilitres.

Half of this is 100 millilitres.

Pause the video, whilst you complete your talk task.

Click Resume when you are ready.

Let's go through the answers.

I have 500 millilitres.

Double this is one litre.

I have one litre.

Half of this is 500 millilitres.

This is where of.

at the start of the lesson, we talked about how many millilitres there are in one litre.

This helps us to convert and compare the amounts.

Because I know that there 1000 millilitres in a litre, which 500 millilitres is half of.

I have one litre.

Double this is two litres.

I have two litres.

Half of this is one litre.

I have nine.

90 millilitres.

Double this is 180 millilitres.

I have 180 millilitres.

Half of this is 90 millilitres.

How did you do? Well-done.

Now we're going to look at comparing and ordering amounts.

Who has the most milk? Who has the lease milk? Explain your answer.

I'm going to pause to give you time to think.

Are you ready? Can you whisper to the screen? Who has the most? The least? And explain why? Off you go.

Well-done.

Who has the most milk? Amy has the most milk.

One litre is the same as 1000 millilitres.

1000 millilitres is greater than 500 millilitres, 180 millilitres and 20 millilitres.

Who has the least milk? Harry has the least milk.

20 lit.

20 millilitres is the least amount.

Can you order these volumes from least to greatest? I'm going to pause again to give you time to think before we go through the answers.

Are you ready? Can you tell the screen? The amount that is the least.

Well-done.

20 millilitres is the least amount.

Here you can see.

We got the greater-than and less-than sign with the least pointing this way.

So this volume is less than the next one.

This volume is greater than 20 millilitres.

What's the next? Tell the screen.

Well-done.

It's 180 millilitres.

And then what's the next amount? Super! 500 millilitres.

And the greatest amount is one litre.

That's why it's important to remember there are 1000 millilitres in a litre.

Can you tell the screen? Now repeat after me.

1000 millilitres equal one litre.

You turn.

Well-done.

Now it's time for your independent task.

For your independent task today, you've got some questions asking you about who has the most and the least amount of milk.

Then you are to order the amounts from least to most.

And just like the task we've just done together, we have the less-than and greater-than sign.

There I would like you to order the amounts.

Don't forget to.

the unit of measure.

Is it measuring in litres or millilitres when you are comparing the amounts? Pause the video to complete your task.

Resume once you're finished.

let's go through the answers.

What has the most milk? Well, the most amount is Ian.

He has 600 millilitres.

Who has the least milk? Well, Nessa has the least milk, because she has 200 millilitres.

That's the least amount our of the four volumes.

Let's put them in order.

Nessa starting with 200 millilitres.

Then it's 400 millilitres.

Then it's 500 millilitres.

And then it's 600 millilitres.

How did you do? Well-done.

Now you needed to order the measurements.

This one was a bit trickier, because you had a mixture of millilitres and litres.

So the least amount was 8 millilitres.

Then it was 80 millilitres.

Then 88 millilitres.

And then 8 litres.

This is the next least amount.

But it's greater than the other amounts, because 8 litres is the same as 8000 millilitres.

And then 80 litres is the same as 80,000 millilitres.

And then 88 litres is the same as 88,000 millilitres.

Well-done on a great lesson.

Now it's time for you to complete your quiz.

I hope you enjoy today's lesson.

And I hope to see you again soon.

Bye.
