Lesson video

In progress...

Well, hello there, math stars.

It's Mrs. Khaira, and it's my wonderful assistant, Patch.

Now today, we're looking at knowing one more than any given number within 15.

Now, Patch and I practised this this morning when we had our breakfast.

Shall I show you what we mean? Now, here is Patch, and here is his cereal.

Now, for breakfast, Patch normally likes to eat six pieces of cereal.

One, two, three, four, five, and six.

But today, he was feeling extra hungry.

He asked for one more piece of cereal, so I gave him one.

How many pieces of cereal does Patch have now? Well, I think we can count them up to find the answer.

One, two, three, four, five, six, and seven.

One more than six is equal to seven.

Now, for today's lesson, you're going to need the following items. Firstly, you're going to need some countable objects.

So, I'll be using cubes today, but perhaps you might have a bead string or some counters handy that you can use instead.

And secondly, you'll need the number cards, which have been provided in today's lesson resources.

Now, if you haven't got these things ready, please press the pause button now, go and get the items you need, find a quiet spot, and then resume the video when you're done.

Now, let's have a look at our big picture for this unit.

It comes from Old Mother Hubbard, a nursery rhyme.

Shall we sing the first verse together? Get your singing voices ready! ♪ Old Mother Hubbard ♪ ♪ She went to the cupboard ♪ ♪ To fetch her poor doggy a bone ♪ ♪ But when she got there ♪ ♪ The cupboard was bare ♪ ♪ And so the poor doggy had none ♪ Aww, poor Patch.

Hungry again.

Well, I wonder if we can cheer him up by looking closely at the big picture and answering some questions.

I think you could help me with this.

So, let's have a look at the picture then.

I want to know how many trees there are in the picture.

I've put a circle around one so you can see it.

How many trees can you spot? Let's see if you're correct.

Let's use our careful, counting fingers to find the answer.

One, two, three.

There are three trees in the picture.

Can you help me represent them using our bead string? So, let's represent the number three using our bead string.

One, two, and three.

There we have our three beads representing the three trees in the big picture.

That was great counting, everyone.

I wonder if you can help me out with one more question.

This time, I want you to see how many cups of orange juice you can count in the picture.

Have a good look.

Hmm.

I wonder if you got the same number that I did.

Let's count together.

Let's go.

One, two, three, four, and five.

I can see that there are five cups of orange juice.

Let's represent these cups of orange juice using some lolly sticks this time.

Are you ready? Let's count them out together.

Here we have one, two, three, four, and five.

These five lolly sticks represent the five cups of orange juice.

Well, let's have a look at our new learning.

Today, we're going to be finding one more than any given number within 15.

And there's a reason why I need your help on this.

It's because every time I give Patch a bone, he asks me for one more.

What a greedy dog.

Well, I wonder if you could help me with this example and help me find out what one more than this number might be.

So, we're going to pick a number card.

Let's see what number card we picked.

Ooh, the number 13.

Now, I'm going to represent the number 13, and I'm going to use my cubes to help me do that.

Can you help me count 13 cubes? Are you ready? One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13 cubes.

I have represented the number 13 using 13 cubes.

Now, we want to identify what one more than 13 is.

Do you think you know how we might do that? I think Patch might have an idea.

Oh, Patch, you are so smart.

He said if we add one more cube, then we will find more than 13.

So, let's do that.

There we go.

We've added one more cube to our tower.

Now, how many cubes do we have all together? Can you shout the answer out to the screen? Great work, everyone.

That's right! One more than 13 is 14.

That's because 13 plus one more is equal to 14.

Great work, everyone.

Now, it's your turn to have a go.

For today's Talk Task, you're going to need your number cards and some cubes to represent the number you pick.

You're also going to need the help of your talk partner.

So, Patch, are you ready to go.

Patch is nodding.

Right, Patch is going to pick me a number card.

So, let's see which one he has chosen.

Oh, he's picked a nice, big number.

He has picked the number 10.

Great work, Patch.

Now, let's have a go at representing the number that Patch has picked.

We will need 10 cubes to help us do that.

Are you ready to help me count them out? Let's go.

One, two, three, four, five, six, seven, eight, nine, and 10.

All together, I have got 10 cubes representing the number 10.

Now, I want to find one more than 10.

So, can you remember what we need to do to do that? That's right.

We have to add one more cube.

Let's do that together now.

I wonder how many we have all together now on the screen.

How many cubes do we have? That's correct.

We have got 11 cubes.

That's because one more than 10 is equal to 11.

10 plus one more equals 11.

Now it's your turn to have a go.

So, in a moment, you're going to gather all your equipment and press pause button.

Once you've had a go at the activity with your talk partner, resume the video, and we'll carry on with our learning.

Great work, team.

Now, let's explore the concept of one more than in a little bit more detail.

Let's see which number we've picked for this example.

We have got the number 14.

Now, let's see if we can represent the number 14 using our cubes.

I'm going to need your help to count them.

Are you ready? One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, and 14.

Great counting, everyone.

Now, there's my number 14 represented in cubes.

Now, we want to find one more than 14 cubes.

So, we are going to add one more cube to our tower.

How many cubes do we have now all together? Can you should out the answer? That's great, everyone.

Correct! One more than 14 cubes is equal to 15.

That's because 14 plus one more is equal to 15.

Great work, everyone.

Now, we might also choose to represent this using a number line.

So, have a look at the number line.

Can you find the number 14? And point to it for me.

Good work, everyone! There is the number 14.

Now, when we look on a number line, we use the language of one greater than.

One greater than 14 is the number that comes straight after it.

So, can you see which number comes after 14? Great work, everyone.

That's correct! The number that comes after 14 is the number 15.

One greater than 14 is equal to 15.

Great learning, everyone.

Well, now it's your turn to have a go.

So, using your number cards, your cubes, or other manipulatives, and the use of the number line, have a go at exploring the language of one more than and one greater than.

Once you've had a go at the activity, you can resume the video, and we'll finish off with our learning for today.

Welcome back, everyone.

I hope you enjoyed the activity as much as Patch and I did.

We had a great go of it earlier.

Now, let's revise our learning from today by having a look at one more example.

So, here we have the number card with the number seven on it.

Let's represent the number seven using our cubes.

We're going to count seven cubes out together.

Let's go.

One, two, three, four, five, six, and seven.

Now, I want to find out what one more than seven is.

I know that I have to add one more cube.

All together now, I can see that I have got eight cubes.

That's because one more than seven is equal to eight.

Great work, everyone.

Now, we can also see this on our number line.

Here, we have a number line from one to eight.

Can you point to the number seven for me? That's right, there it is.

Let's put the circle around it.

Now, when we talk about numbers on our number line, we use the language of one greater.

One greater than seven is eight.

And that's because number eight comes straight after the number seven.

Fantastic learning, everyone.

I think we've got that down.

Now, in lesson five, we'll be looking at identifying one fewer than any given number within 15.

Patch and I look forward to seeing you then.

Bye for now!.
