Lesson video

Hello, my name's Miss Jones, and I'm going to be teaching you math today.

I'm going to start with telling you a joke.

Are you ready? Why were the two fours not hungry? Go and tell me why you think the two fours might not be hungry.

Should I tell you? The two fours were not hungry because they already ate.

Let's start today's lesson.

Today we're going to be consolidating and reviewing learning on capacity and volume.

Here's the lesson agenda.

We'll start with the new learning where we'll be recapping capacity, volume, and temperature and reading scales, as well as looking at word problems. Then there'll 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 today's lesson.

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

Let's start by looking at temperature.

Here we have two thermometers.

Thermometer A and thermometer B.

What is the temperature on this thermometer showing? Now, to find the temperature we need to remember we need to look at the intervals the scale is going up in and what each mark represents.

Pause the video whilst you work out the answer for this reading.

Are you ready? Let's look at it together.

Let's count the intervals the scale is going up in.

Count with me.

Zero, five, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80.

Go on tell the screen the number the scale is going up in.

Well done.

The intervals are going up in five.

Now we need to find what each mark represents.

Count with me, let's start with ones.

One, two, three, four, five, and I landed on five so I know that each mark represents one.

Now let's look at the reading that we've been given.

The red line indicates how hot something is and the line stops here, which is one above 45.

One more than 45 is, go and tell the screen.

Well done, 46.

This recording on this thermometer reads as 46 degrees Celsius.

Can you say that back? Well done.

Now let's look at thermometer B.

The temperature is 10 degrees higher than thermometer A.

Show this on the thermometer.

I'm going to pause again to give you time to show where this mark might be.

Can you point to where that would be on the thermometer? Great! Well, you're right.

The mark would be at 56.

10 more than 46 is 56 degrees Celsius.

Now let's look at some problems involving temperature.

Read this one with me.

The temperature in Portsmouth is 22 degrees Celsius.

It is three degrees warmer than the temperature in Birmingham.

What is the temperature in Birmingham? The temperature in Birmingham is, and then your answer would go here.

Let's read the second one together.

The temperature in Cardiff is five degrees colder than the temperature in Brighton.

The temperature in Brighton is 21 degrees Celsius.

What is the temperature in Brighton? The temperature in Brighton is.

Pause the video whilst you work out the answers for these two questions.

You may wish to draw a bar model to help you.

Don't forget the unit of measure.

Are you ready? Can you tell me the temperature that it would be in Birmingham? Go on, whisper it to the screen now.

Well done.

The temperature in Birmingham would be 19 degrees Celsius.

The whole number would be 22 degrees and it's three degrees warmer.

So three of those parts are taken away.

Three less than 22 is 19.

How about the temperature in Brighton? Go on, whisper to the screen now what you thought the answer would be.

Super! Well, you're right.

It is 16 degrees.

The temperature is going down.

It's getting colder.

So 21 and five less is 16.

Now we have some measuring jugs.

On these measuring jugs, they've got some of their intervals on the scale not marked up.

Can you tell me what each mark represents and record it on your piece of paper.

Remember to look at the intervals carefully to see what the scale is going up in and what each mark represents.

Pause the video whilst you complete this task.

Click Resume when you are ready.

Let's go through the answers.

Let's look at the intervals on this scale together.

Count with me.

Five, 10, 20, 25, 30, 35, 40, 45.

Did you notice what the scale is going up in? You're right.

It's going up in fives.

So it would be five, 10, 15 millilitres.

Now let's look at the second container.

Count with me.

Two, four, six, eight, 10, 12.

Can you work out what it's going up in? Go and tell me.

Super, it's going up in twos.

Let's continue counting until we find the missing value.

14, 16, 18.

Tell the screen.

Brilliant! 20 millilitres.

And then the final container.

Let's look at the intervals together.

10, 20, 30.

It's going up in tens.

So the next number would be.

Go on, whisper it to the screen.

Great work! 40 millilitres.

Now it's time for your talk task.

For your talk task today, I would like you to convert the following measurements.

3000 millilitres is the same as how many litres.

Six litres is the same as how many millilitres.

And half a litre is the same as how many millilitres.

Remember the fact, if I know that there are in one litre, I know that.

Pause the video whilst you complete your talk task.

Click Resume when you are ready.

Let's go through the answers.

Let's talk about this fact first.

If I know that there are 1000 millilitres in one litre, then I know that 3000 millilitres is the same as, tell the screen, three litres.

Well done.

Six litres is the same as 6,000 millilitres.

And half a litre is the same as 500 millilitres.

Now let's look at some word problems. Read this one with me.

Alex had 100 millilitres of water.

Claire had half the amount of water that Alex had.

How much water did Claire have? Joe had some water.

He had half the amount of Becky, who had 200 millilitres.

How much water did Joe have? Don't forget your units of measure.

And remember you can draw bar models on your piece of paper to help.

Pause the video whilst you have a go at these word problems. Click Resume when you are ready.

Are you ready? Let's go through the answers.

Alex had 100 millilitres of water.

Half this amount, that would be 100 shared into two parts.

That means Claire had 50 millilitres.

50 millilitres and 50 millilitres equals 100 millilitres.

Joe had half the amount of Becky.

Becky had 200 millilitres.

Half means there will be two equal parts.

200 shared into two equal parts is 100 millilitres.

Joe had 100 millilitres.

Now we're going to recap using the less than or greater than symbol to make the statement true about the volume of water in each beaker.

Look at the volume of water in each beaker carefully and decide which symbol you would use in this equation.

Pause the video whilst you do this task.

Let's talk about it together.

Can you tell the screen now which amount is the greatest amount? Great.

Now can you tell me why? Brilliant.

473 millilitres is greater than 369.

473 is greater because 473 has more hundreds than 369.

Now it's time for your independent task.

For your independent task today, you have two word problems to solve.

Here's the first one.

Let's read it together.

Each cup holds one litre of water.

Here are the cups.

Bucket A, here's the bucket A, holds how many litres of water? Bucket B holds how many litres of water? Bucket B holds how many litres more than bucket A? Then your second question.

There are 10 ladles of soup in a large pot.

The soup is poured into three small bowls, A, B and C.

Bowl A has more soup than bowl C.

Bowl B has more soup than bowl A.

Can you estimate how many ladles of soup are in each bowl? Remember the ladles have to total to 10.

Can you find more than one answer? Pause the video to complete your task.

Resume once you're finished.

Let's go through the answers.

If each cup holds one litre of water, then we have one litre, two litre, three litres for bucket A.

If bucket B has one, two, three, four, five cups, then it will hold, the bucket will hold five litres of water.

If bucket B has five litres and bucket A has three litres, then bucket B has two more litres than bucket A.

How many ladles are in each bowl? Bowl A has three ladles, Bowl B could have five ladles and Bowl C could have two ladles.

If you've found any more ways, can you tell the screen now? Great work! Well done for working so hard.

I hope you've enjoyed solving all those problems and I hope to see you again soon.

Bye!.
