Lesson video

Hello mathematicians is Ms. Charlton here and my talk partner Hedwig.

Have you got your talk partner ready for the lesson? If not, quickly go and get someone now.

It's important to be able to practise your mathematical thinking with them.

Let's get started and see what we are going to learn today.

So we are going to compare, numbers to 20.

First of all, we're going to compare some teens numbers like 13, 14, 15, 16.

Then we're going to use the language of comparison.

So you're going to learn some new language today to use.

Then you'll do your independent task, and an end of lesson quiz.

Today you're just going to need a pencil and some paper.

I don't know about you, but I need my brain warming up a little bit today.

Let's start off with a brain teaser.

We've got some numbers down the side, and then we've got the written words on the other side and we need to match up the ones that go together.

Hmm, let's have a look carefully.

The first one says 15.

Can you find the word representation of 15? Let's all look at those now.

And then we'll check the answers together.

Hmm.

Let's go through them, shall we? Are you ready? 15, there's 15, fifteen.

Can you say 15, 15? Well done, it's a bit funny that one, isn't it? Because I can see that it's number five.

We don't say five-teen, we say fifteen.

Now 17 is a little simpler, because I can hear the words seven there, S-E-V-E-N, seven-teen.

12 is a tricky one as well, because that's a number two.

And that doesn't sound like 12, twelve, well done.

And then 11 is a bit tricky as well.

11, 11 is one 10 and one one, that's eleven.

Hopefully you're nice and warmed up now, ready for our lesson.

Get your hands ready to do our star words.

Hands up star words! Greater, less, more, compare, fewer.

Those are the languages, the words, of the language of comparison, that we were talking about just before, that we're going to need for today's lesson.

We've got a giant there and he is busy counting his money.

He looks quite happy with the amount of money he's got.

But what we're going to do, while he's busy counting his money, we're going to look at the flowers.

So let's look very carefully the flowers.

Hmm, how many can we see? Let's try and count them carefully.

Let's count the blue ones first.

One, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen.

Oh, and there's one up near his elbow, that's number 15.

So there are 15 blue flowers.

I nearly missed that one by his elbow.

So those are the blue flowers.

There are 15 blue flowers.

Well done.

Now let's count the red flowers, let's count them carefully.

One, two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen.

There are 13 red flowers.

Can you say that? Well done.

There was another one hiding up by his elbow as well, I nearly missed that.

Now what we need to do, is compare, the number of blue flowers and red flowers.

Compare, means to see which one has a greater value, and which one has a smaller value.

Let's look more carefully.

I'm going to play this video, and I'm going to show you, how I used, breadsticks to represent the tens, and raisins, to represent the ones, to show you how I could compare the two numbers.

So, first of all, I drew out my tens and ones and I knew I needed to compare the number 13, and the number 15.

So let's have a look.

13 has got one ten.

So I use a breadstick to represent my tens.

There's one 10, and it's got three ones.

So my raisins, I needed three raisins.

one ten and three ones.

Then I had look at the 15.

I can see it's got one ten and five ones.

So I counted up, five raisins to represent my ones.

One, two, three, four, five.

I can see that 13 has one ten and three ones, and 15 has one ten, and five ones, which means that there are more ones here.

So 15 has a greater value.

Can you see how we compared the two different amounts there? So I can see that there are 15 blue flowers and 13 red flowers.

Let's have a look at that, using the language of comparison.

Now we go to on cubes, there were 15 blue flowers, the cubes show a group of ten and five more, just like I did with the breadsticks and the raisins, a group of ten with the breadstick and five more, five raisins.

And the red flowers, there are 13 red flowers, a group of ten and three more.

Remember how we saw that on the tens and ones, one breadstick and three raisins.

15 has got one ten and five ones.

13 has got one ten and only three ones.

So there are more blue flowers than red.

Can you say that? There are more blue flowers than red.

Well done.

There are fewer red flowers than blue.

That's the language of comparison.

Those are all star words.

More, fewer.

There are more blue flowers than red, because the blue flowers, there are 15 and 15 has got five ones.

But the red flowers, they're only 13, and 13 has only got three ones.

Lets have a go at comparing something else.

Now it's your turn.

Can you have a look at the number of flags, and the number of windows on the castle, and see if you can compare, how many flags there are, and how many windows there are.

If you want to just use the picture to count, you can, maybe you might like to use some counting objects yourself.

So if you do want to do that, you could use raisins like I did, and breadsticks, or you might have coins, or buttons at home or counters.

You could even use pieces of pasta to count as well.

Otherwise, just use the picture provided.

Pause the video now, and then come back and we'll check them together.

Did you get the same as me? I counted the windows, and I saw that there were 18.

The windows were those tiny blue triangles there.

It was quite tricky to count them, wasn't it? So, we had 18 windows.

18 is a group of 10, and eight ones.

But there were 11 flags.

11 is one group of ten, and one one.

18 has got one ten and eight ones.

11 has got one ten and one one.

It sounds a bit funny saying one one, doesn't it? But you need to remember that, that's how we represent the ones.

So you can still say one one.

So, let's use the language of comparison.

There are more windows than flags, there are fewer flags than windows.

Let's say that together.

There are more windows than flags, There are fewer flags than windows.

Fantastic use of that language, I think we need a celebration.

Shall we have a Hulk clap? Ready? Hulk! Brilliant job.

Now it's your turn to compare some different prices.

Now you're so lucky, you get to go to the sweet shop.

Well, the pretend sweet shop anyway.

You've got lots of different sweets here and chocolates, and you get to compare the prices of them.

What I want you to do, is choose two different sweets to compare, and have a look at how much they cost.

You can use the tens frame to help you, if you want to count out, using raisins to help.

Otherwise, you can identify the tens and the ones.

So for example, if I wanted to compare this sweet here, the red one, and the pink and yellow sweet at the bottom, I can see that the red sweet, is 11 pence.

It's got one ten, and one one.

Let's count right out.

Here's my group of 10, one ten, and one one.

And the pink and yellow sweet, has got one ten, six, seven, eight, nine, ten.

That's my group of ten.

And three ones, one, two, three.

So which one costs more, huh? I can see the pink and the yellow sweet costs more, than the red sweet.

Pause the oop! Pause the video now, if you want to have a go at your activity and then come back, and work out about it afterwards.

Now you will all have compared the different sweets in a different way.

So we can't check our answers together, because you'll all have done different comparisons.

But I want to know who compared the chocolate, and the pink and yellow spotted sweet? pop your hand up, if you compare those two.

Did you find that the chocolate costs more than the pink and yellow spotted sweet? You should do because the chocolate has got two tens and the pink and yellow spotted sweet has just got one ten and seven ones.

Who compared the red sweet and the green sweet, the green and yellow sweet? Put your hand up, if you compared those.

Hopefully you had a really great time using the language of comparison, at your sweet shop.

You're did a really great job learning today everybody, should we wake up Hedwig up and tell her what we learnt about? Wakey, wakey Hedwig.

Wakey, wakey.

Now, what did we do today? Well, we learned some new vocabulary, the language of comparison.

We needed to identify how many tens there were and how many ones there were in a number, so that we could then say which one there were fewer of, and which ones there were more of.

Do you think you understand? I think she enjoyed the lesson.

Well done everybody.

You did a fantastic job, go on do your quiz and I'll see you again very soon, bye.
