Lesson video

Hello, my name's Mrs Cornwell and I'm going to be helping you with your learning today.

I'm really looking forward to working with you and I know together we're going to do brilliantly.

So let's get started.

Welcome to today's lesson on 'More Than and Fewer Than' which comes from the unit counting, recognising and comparing numbers zero to 10.

You're going to be using some of your counting skills to help you face new challenges.

And by the end of today's lesson, you will know how to compare 2 or more groups of objects and describe them using more than and fewer than.

So here are the words that are going to be important for our learning today, more than, fewer than, equal and compare.

And we're going to be using those words throughout the lesson to help us today.

So the first part of today's lesson is to compare 2 groups using more than and fewer than.

When comparing groups of objects by counting, one group can contain more objects than the other, and one group can contain fewer objects.

If we have a look there, we can see 2 groups.

I can count 3 bricks in that first group.

I can count 1 brick in that second group.

So we say that this first group has more because there's a larger amount of objects and this second group has fewer because there's a smaller amount of objects.

So here's Jun, and Jun is having a birthday party.

He wants to give each of his friends a hat.

There are his friends and there are some party hats.

Are there enough hats for everyone? He needs to find out.

Think, are there more children or more hats? I wonder how he can find out.

In comparing groups of objects, first put one group of objects in a line so we can see that the children are lining up here, Jun and his friends.

Then match them to compare.

So we're going to match 1 hat to each child that's there.

So when we do that, we can see that there are more hats than children because the hat line, once they've been matched is longer than the children's line.

So there's the extra hat and there are fewer children than the hats.

We can see the children's line is shorter once they've been matched to the hats, isn't it? So there must be fewer because there's not as many of them.

So there Jun's found out, hasn't he? I have enough hats for everyone.

Here are Jun's presents.

He's got a group of yellow and blue presents.

"When I counted, I had fewer yellow presents than blue presents", he said.

Is Jun right I wonder.

What do we think we could do to find out? Jun says, "I will place the presents in lines to compare them." So he's remembered our learning that we've been doing today, hasn't he? So here he is, he puts his yellow presents in a line.

And then he matches 1 blue present to each yellow present.

And then he counts 1, 2, 3, 4.

There are 4 yellow presents.

1, 2, 3.

There are 3 blue presents.

He didn't need to count because when you've matched the objects you can see that the line with longer has more in the group and the shorter line has fewer in the group.

But he counted as well just to make sure didn't he? So he found out there are more yellow presents than blue presents.

And there's the extra yellow present.

There are fewer blue presents than yellow presents.

So he's corrected himself there.

He says, "I have more yellow presents than blue presents." He found out by comparing them and matching, didn't he? His 2 groups of objects, which group has more? So we can see a group of yellow presents.

And they're very large, aren't they? They're very big.

And a group of smaller blue presents.

I wonder which group has more, what can we do to find out? That's right.

First put the presents in a line.

We can see we put the yellow presents in a line there.

I wonder what we'll do next.

That's right, we match them up, don't we? We match 1 blue present to every yellow present that's there.

And when we do that, we can see that the blue line is longer.

So what does that mean? 1, 2, 3, 4 yellow presents.

1, 2, 3, 4, 5, 6 blue presents.

So he's also counted them and he can see that even though the yellow presents are larger, there are more blue presents than yellow presents.

He counted and he could see there were more.

But also when he matched and compared, he could see the blue line was longer.

So that means it had more presents.

And the yellow line presents was shorter.

So that means it had fewer presents.

And there's the 2 extra blue presents.

And now here's Sofia and she says, "There are fewer green hats than orange hats." So look, she's lined her 2 sets of objects, her 2 groups of objects up, hasn't she? But what is her mistake? What has she forgotten to do? I wonder.

Sofia placed the hats in a line but did not match them up.

So here's her green hats that she's put in a line.

And she's matched 1 orange hat to each green hat that's there.

Then she counts as well, doesn't she? 1, 2, 3, 4, 5 green hats.

1, 2, 3, 4 orange hats.

And she says there are more green hats than orange hats when she matches each of the groups to each other.

Show all the orange hats to the green hats.

She can see that there are more green hats and there are fewer orange hats.

Here's Izzy, and she says, "We can easily see how many are in each group if we match them to the numerals on a number track." Here's a number track with the numbers 1 to 10.

And she's matching her hats to each number.

So 1 hat to each number on the track.

And then when she's done that she can see that there are more green hats than orange hats because if you look, there are 5 green hats and there are only 4 orange hats there aren't there? So there are fewer orange hats than green hats.

So here we have 2 sets of objects.

We've got a set of presents and a set of party hats.

And we want to compare the different groups.

We're going to find out are there more hats or more presents at the party? Perhaps you could use cubes to represent your presents and counters to represent your party hats.

And then you can use what you find out to help you to complete the stem sentences.

So you can see that one there.

There are more mm than mm.

There are fewer mm than mm.

Okay, so pause the video while you try and have a try at the activity.

Well done.

So let's see how we did.

So that's right.

First you had to line them up, didn't you? So there you can see we're lining up the yellow presents.

Then we have to match them.

We need to match 1 party hat to each present.

And when you do that, you can see that there are more party hats and presents because that line is longer when it's been matched.

And you can see that there are fewer presents, can't you? Remember, if we match them to a number track, we can easily see how many are in each group.

So we can see there that there are 4 presents because we've matched 1 present to each number on the number track.

And we can see that there are 5 hats.

So there are fewer presents than hats.

There are more hats than presents.

Here's Izzy and she says, "There are fewer children than hats." So have a look, she's lined both of her groups up again, hasn't she? So do you agree with Izzy? Do you think there are fewer children than hats? Perhaps you could use some counters to represent the hats.

Some green counters maybe and some counters to represent the children.

So you can compare the 2 groups.

Pause the video while you have a try.

Well done.

Okay so let's see what you did then.

We need to match the hats to the children to check, don't we? 1, 2, 3, 4, 5 hats.

And when we match a child to each of the hats and we can see there are more children than hats.

So Izzy did put them in a line, didn't she? But she forgot to match them up.

So she spread her hats out and it looked like that line was longer but she hadn't matched them.

So when you match them up, you can see actually that line's shorter and there are fewer hats than children, more children than hats.

And there's the extra child there, we can see.

So, but we could also use a number track to compare.

We can see, we can match a hat to each number and a child to each number.

When you do that you can see that there are more children than hats and there are fewer hats than children.

So here are some presents from Jun's party and it says are there more yellow presents or more blue presents? What do you think? Look carefully at those groups and think about what we've been doing to compare so far.

Ah did you spot it? Yes, that's right.

Both groups have the same amount, don't they? So when 2 groups have the same amount of objects, we say that they're equal.

There is an equal amount of yellow and blue presents at Izzy.

So neither set has more and neither set has fewer.

They both have an equal amount.

So yes, let's use that learning and see if that can help us solve this problem.

Which 2 groups of presents are equal? So we've got 3 groups there, haven't we? Can you spot which 2 groups are equal? So you could use some counters, blue counters to represent the blue presents.

Yellow counters to represent the yellow presents.

And pink counters to represent the pink presents, couldn't you? So pause the video while you have a try.

Well done.

Did you spot it? That's right.

So the blue presents have an equal amount to the pink presents.

The length of the line is the same, isn't it? So they both have the same amount once they've been matched.

So we could put them on a number track, couldn't we? And we can see that they both have an equal amount.

They both have 5.

So there is an equal amount of blue presents and pink presents.

The blue group has the same amount as a pink group.

So they are equal.

That's right.

Well done.

So Jun has these cups for his party and we can see his cups there, can't we? And he says, "I have more straws than cups at my party." How many straws could there be? So think about what he's going to have to do to compare his group of cups to his group of straws.

That's right.

So first of all, to find out how many straws there could be, he needs to put one group into a line.

So you can see he's put his group of cups into a line there, can't you? I wonder what he'll do next.

So we can explore this together using our pencils to represent the straws, can't we? I think that's probably what Jun will have done.

He will have got the straws and he will have tried to match them up to compare won't he? So we can see that there are 6 cups there and we start with 1 straw for each cup.

So we don't need to count because we know that if we have 1 straw for each cup, there will be an equal amount.

They will both have 6, won't they? So we start our count at 6 and we count 6, 7.

So Jun could have 7 straws.

6, 7, 8.

Jun could have 8 straws.

6, 7, 8, 9.

Jun could have 9 straws.

6, 7, 8, 9, 10.

He could have 10 straws, couldn't he? Because all of those are more than the 6 cups.

Could he have more than 10 straws, do you think? That's right, he could couldn't he? There are lots of numbers that are more than 10.

Could have had 11 or 12 or some much bigger numbers.

But we just looked at the ones that we've got on our number track today.

But there were lots of other answers you could have had to that as well.

Well done.

So Jun has these balloons for his party.

Can you see his balloons there? Jun says, "There are fewer children than balloons left at my party." So some of them must have gone home.

So he has fewer children than the balloons there.

How many children could there be? So let's explore this together using counters to represent the children.

Remember this time there are fewer children than balloons.

So there's one of the children and we can see the set of balloons, we can see that there are 6 there 'cause they've been matched to the numbers on the number track.

So we start our count at 1 this time and we count.

So 1, there could be 1 child.

That 1 child would be fewer than 6 balloons.

There could be 2 children.

There could be 3 children.

There could be 4 children.

There could be 5 children.

Could there be 6 children? What do you think? Explain how you know.

That's right.

There couldn't be 6 children could there? Because if there was 6 children, the group of balloons and the group of children would be equal.

So to be fewer than 6, we've got our answers there, haven't we? There could be 1, 2, 3, 4 or 5.

So here's your task for today.

Here's Jun and he says, "I have 5 candles on my cake." 'At my birthday party, I had more candles on my cake than Jun", says Alex.

And there's Alex in the corner there.

So how many candles could Alex have had? He had more candles than Jun and Jun had 5, didn't he? So you could use some pencils again to represent your candles, couldn't you? While you try and work that out.

, pause the video while you have a try.

Okay, and then we have got Jun again here for the second part of your task.

And he says, "I have 5 candles on my cake." And there's Andeep this time.

And Andeep is saying, "At my birthday party, I had fewer candles on my cake than Jun." How many candles could Andeep have had? So Jun had 5 but Andeep had fewer.

So again, you could use your pencils to represent the candles and compare the groups, couldn't you? So have a think about what you will have to do for that problem.

Pause the video while you try.

Let's have a look at the first part of our task then.

How many candles could Alex have had? So we can see Jun's 5 candles there.

We can see against the number track that there are 5.

And Alex had to have more candles, didn't he? So we're going to use pencils to represent Alex's candles.

And there are the 5 pencils to represent Alex's 5 candles.

And he has to have more than 5, doesn't he? So how many could Alex have? So Alex could have, we start our count at 5, don't we? 'Cause we know that would be equal to Jun's candles, and we count.

5, 6.

Alex could have 6 candles.

5, 6, 7.

He could have 7 candles.

5, 6, 7, 8.

He could have 8 candles.

5, 6, 7, 8, 9.

He could have 9 candles.

And 5, 6, 7, 8, 9, 10.

He could have 10 candles, couldn't he as well? 'Cause all of those would be more than 5 candles.

Could he have more than 10 candles, do you think? That's right.

There are lots of numbers that are more than 10.

We've just shown the ones on the number track.

But you may have had some much larger numbers.

Well done.

You've worked hard with that.

So now let's have a look at how many candles Andeep could have.

So we can say, see Jun's 5 candles there.

And we know Andeep had to have fewer candles than Jun.

So there are Jun's 5 candles and we're going to again use pencils to represent Andeep's candles.

We start our count at 1 and we count.

So Andeep could have 1 candle.

1 candle would be fewer than 5 candles.

He could have 2 candles, 3 candles, 4 candles.

Could he have 5 candles? I wonder, what do you think? No, that's right.

He has to have fewer than Jun doesn't he? So he couldn't have 5 candles because 5 candles would be equal to Jun's group.

That's right.

Well done.

You've worked really hard in the first part of our lesson and I hope you've found out lots about comparing and matching.

And we're going to use that in the next part of our lesson.

So the next part of our lesson is using what we've already found out so far today.

And we're going to use that to compare more than 2 groups using the language more than and fewer than.

So here are the hats Jun has for his party.

We can see he's got a set of green hats, a group of green hats, a group of orange hats and a group of blue hats.

Let's use our learning to describe which group has more and which group has fewer.

So to compare the groups, arrange them in a line and match them.

We can see we've got a number track there to help us see how many are in each group.

So we can match the green hats, one to each number and the orange hats and the blue hats.

Okay, and then when we've got them matched in their lines, we can compare to see which set has more, which group has more and which group has fewer.

Okay, so remember the line that has more will be the longer line when they're matched.

And the line that has fewer will be the shorter line.

So what could we say to describe those groups? That's right, we could say there are more orange hats than green hats.

'Cause we can see the orange line is longer than the green line.

We could say there are more orange hats than blue hats 'cause the orange line is also longer than the blue line, isn't it? We can see that there are fewer blue hats than green hats.

The blue line is shorter than the green line.

We can see there are fewer blue hats than orange hats, can't we? 'Cause the blue line is also shorter than the orange line.

And there are more green hats than blue hats.

So did you get any of those sentences? Well done if you did.

See if you can use what we've learned to help you solve this problem.

So we've got 3 groups of presents again here, haven't we? And we want to describe them, compare them and then describe using the language there are more mm presents than mm presents.

And there are fewer mm presents than mm presents.

So perhaps you could use cubes or counters.

Yellow ones for the yellow presents and blue ones for the blue presents and pink ones for the pink presents to help you.

So pause the video while you have a try.

Okay, well done.

So let's see what you did then.

So first you have to arrange the objects into a line and match them and we can see that we've done that there, haven't we? And we can see without counting, by looking at the numbers on the number track that the yellow group of objects has 8 in it.

The blue group has 3 and the pink group has 5.

So we can see that there are more yellow presents than pink presents because the yellow line is longer than the pink line.

We can see there are more yellow presents than blue presents as well.

So again, the yellow line is longer when they've been matched.

There are more pink presents than blue presents 'cause the pink line when they've been matched is longer than the blue line.

But there are fewer pink presents than yellow presents 'cause the pink line is shorter than the yellow line when they've been matched up.

There are fewer blue presents than pink presents again.

We can see that the blue line is shorter than the pink line.

And there are fewer blue presents than yellow presents as well, aren't there? Well done.

So here are some of Jun's friends and they've collected some balloons.

So let's compare the balloons Jun's friends collected at his party.

And you can see there's Aisha, Izzy, Andeep and Jacob.

And we're going to compare to think about who has more and who has fewer.

We're going to point to the child who has fewer balloons than Andeep, but more balloons than Izzy.

So remember we can see that the balloons have been matched.

So we can look at how long the lines of balloons are to help us with that, can't we? So first of all, let's see, we know that this child has to have fewer balloons than Andeep.

So there we are.

It has to be fewer than Andeep, but more than Izzy.

So who could that child be? I wonder.

If you put your number track on you can see it has to have fewer than 6, but more than 3.

Have you spotted it? That's right, Jacob has fewer balloons than Andeep, but more balloons than Izzy.

He has 5 balloons, hasn't he? Okay, so let's use what we've learned so far and see if we can use it to help us solve this problem.

So it says, point to the child who has fewer balloons than Aisha, but more balloons than Jacob.

So there are the children, and you can see Aisha's balloons there and Jacob's balloons at the bottom there.

Okay, so have a careful look and think about which child has fewer balloons than Aisha, but more balloons than Jacob.

So have a think about that.

Pause the video while you try and work it out.

So let's have a look.

We've got a number track there so we can see exactly how many balloons each child has.

We can see Aisha's got 8.

Izzy's got 3.

Andeep's got 6.

And Jacob's got 5.

So let's have a look and see which child had fewer than Aisha, but more than Jacob.

So fewer than Aisha there.

So that would be fewer than 8, but more than 5.

Did you spot it? That's right.

It was Andeep.

'Cause Andeep had 6 balloons.

Well done.

So our second task then today is having a look at the cakes that some of Jun's friends ate.

There's Sam and they are saying, "I ate 5 cakes." And there's Lucas.

He's saying, "I ate 10 cakes." Jun says, "I ate more cakes than Sam.

I ate fewer cakes than Lucas." I think there were some hungry children at this party, weren't there? So how many cakes could Jun have eaten? I wonder.

So you could use counters to represent the cakes, couldn't you? To help you work that out.

So pause the video while you have a try.

Let's see how we got on there.

So I'll use counters to represent the cakes.

So we can see there's Sam's cakes and there's Lucas' cakes.

And we've got a number track so we can easily see, can't we? That Sam has 5 cakes and Lucas has 10 cakes.

Jun must have more than 5.

So there we are.

And he must have fewer than 10.

So I wonder how many cakes Jun could have.

"I could have", so let's have a look.

If he had 5, he would be equal to the amount Sam had.

So it can't be 5, but let's see what it could be.

That's right, you could have 5, 6 cakes because that would be more than 5, but 6 would be fewer than 10.

He could have 7 cakes.

He could have 8 cakes.

He could have 9 cakes, couldn't he? How many different answers are there? Could he have 10 cakes, do you think? No that's right.

He couldn't have 10 cakes, could he? Because then he would have the same amount, an equal amount to Lucas.

So how many different answers are there? That's right, there's only four possible answers for that one because there's only four numbers that are in between 5 and 10.

More than 5 and fewer than 10.

So well done with that.

You've worked really hard there and I hope you've learned lots about comparing by matching and finding out.

It's really important to match when we compare.

So let's see what we've learned today then.

So when comparing groups of objects, first arrange them in a line, then match them.

When comparing objects that can be counted we say that the bigger amount has more and the smaller amount has fewer.

When 2 groups have the same amount we say that they are equal.

Well done.

I've enjoyed working with you today and you've worked really hard.

Now you'll be able to use what you've learned today to help you when you are comparing groups of objects.

So well done.
