Lesson video

Well, hello, Maths friends.

It's Mrs. Khaira and my fantastic Maths helper, Elvis, and why I wonder how you're feeling today? I am feeling particularly happy because it's sunny outside.

And when the sun is shining, I always feel good.

Now in this lesson, we're going to be counting up equal groups and adding them together.

I hope you're ready to begin our learning.

We certainly are, let's go.

Now in this lesson, you're going to need the following items. You're going to require some counting objects.

So I've got some counters that I'm going to use.

It also need some coloured card or some coloured pieces of paper or a copy of the groups of animals resource, which is available in today's lesson resources.

Now, if you haven't got these things ready, please press the pause button now.

Collect what you need and then resume the video when you're ready.

Well, let's have a look at the big picture for this unit.

It comes from "Old McDonald Had A Farm" and here is old MacDonald's farm.

I wonder if you can help me to ask some questions about the big picture.

Let's look really carefully at the big picture.

I would like you to tell me how many horses you can see in each field.

You might need a moment to count them.

If you do press the pause button now, and then we'll resume.

So did you manage to count the number of horses in each field? I think we can do this together.

Let's start with the top left field, the light green one.

I can see that there are three horses in this field and I've put a red circle around them.

One, two, and three.

Let's have a look at the middle yellow field.

How many horses are there in that field? Well, look again, there all three horses in that field.

I've put the blue circle around so you can see them really clearly.

Let's move along to the third field.

Now let's see how many horses there are in that field.

Well done, if you said three, there they are.

Let's move down into the bottom left-hand corner.

How many horses can you see in that field? Well, if you said three you'd be absolutely correct.

There's a pink circle around each of the three horses there.

And then the last field, I wonder if you can tell me how many horses there are? Great work, if you said three again.

There are three horses there.

One, two, and three, and I've put a tack with circle around them.

I wonder what you can spot about the number of horses in each field.

We use a special word in Maths to describe, the same number of an item in each group.

So in our five fields, we can see that there are three horses in each one.

That means that there are five groups of three.

The number of horses and each field is equal.

Great work everyone.

This time, we going to have a look at a different animal.

Wait and see how many cows there are in each of old McDonald's five fields.

So have a good look at the big picture.

How many cows can you see in each field? You might need to pause the video to help you to do this.

So let's have a look at the first field at the top left-hand corner.

How many cows did you spot in that field? Oh well, Elvis has an answer.

If you spotted four, then you are absolutely correct.

One, two, three, and four.

I've put a red circle around them.

Let's move along to the second field.

The yellow field.

How many cows did you spot there? Can you shout the answer at the screen? Great work.

Well, if you said four you would be correct again.

Look there they are.

One, two, three, and four.

There are four cows in the second field.

What about in the third field? On the other side with a blue tractor? How many cows did you spot there? I wonder if you can shout the answer loud to the screen again.

Great work.

Now if it's a four, you wouldn't be wrong.

There are one, two, three, and four cows in the third field.

This time let's have a look at the fourth field.

I wonder if you can whisper the answer to your partner.

How many cows do you spot there? I wonder if you're right Elvis.

Let's check together.

That's right.

There are four cows there.

One, two, three, and four.

Four cows in the fourth field.

And in the fifth field, I wonder if you can shout out the answer at the screen.

How many cows did you spot? Great work everyone.

There are four cows there as well.

So you might notice a bit of a pattern.

In our five fields or our five groups there are four cows in each one.

That means that there are five groups of four cows.

We can also represent this using some counters on a map of old McDonald's five fields.

Let me show you now.

So here, our old McDonald's five fields.

One, two, three, four, and five.

Here are the counters that will represent the cows.

Now let's put four counters into each field because there were four cows in each field.

Can you help me count them out? One, two, three, and four.

Four counters in the first field.

One, two, three, and four.

Four counters in the second field.

One, two, three, and four.

Four counters in the third field.

One, two, three, and four.

Four counters in the fourth field.

And one, two, four, and four.

That's four counters in the fifth field.

The counters represent the cows.

And I wonder if you can see how many cows are there altogether in the five fields? Let's count them up together to check.

One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20.

That means there are 20 cows all together in old MacDonald's field.

There are five groups.

And each group contains four cows.

So let's have a look at the Talk Task for today.

For this activity, you are going to need the following things.

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

So I've got Elvis ready to help me.

You're going to need some pieces of coloured card or coloured papers.

So I've got some pieces here already.

You're going need some counters, as I've got here.

If you don't have counters, you can use any other counting object.

And you're also going to need the cards which are resourced in today's lesson resources.

You've got one example of a sheep in the field, on the screen in front of you.

So let's have a look at what we're going to do.

Elvis has picked a card for me, and there it is on the screen.

I wonder if you can have a look and tell me how many sheep you can see in the picture.

Perhaps we can use our careful counting fingers to count them out together.

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

There were eight sheep altogether in the field on the picture.

That means I'm going to represent them using my counters.

Help me count out eight counters.

Let's do this now.

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

We can get rid of the other ones.

There are my eight counters.

They represent the eight sheep.

Now how many groups can you see on the picture? Well, if you said two, you would be correct.

There are two fields in the picture and they represent our two groups.

Now I'm going to be representing our two groups today using pieces of coloured paper.

Now, how many sheep can you see in each field? Let's have a look at the first field.

I can see that there are one, two, three, and four sheep.

That means I'm going to be representing the sheep in that first field, onto my piece coloured of paper.

So let's do that now.

One, two, three, and four.

These are my four sheep.

And this is my first field.

This is a group of four.

How many sheep can you see in the second field? Let's have a count together and see if you're correct.

One, two, three, and four.

There are four sheep in the second field.

So I'm going to be representing my four sheep using the other four counters.

Let's put them into the second field.

One, two, three, and four.

There are my second group of four sheep.

Now altogether, you can see that there are two groups and each group has got four inside it.

Two groups of four is equal to eight sheep altogether.

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

So in a moment, you're going to press the pause button, get all the resources you have in front of you and have a go at the activity with your talk partner.

You're going to have a go representing the picture cards, using your concrete materials.

Once you've had to go and your partners had to go, please resume the video and we'll carry on with today's learning.

So let's have a look at another example this time.

This time we've got some cows in some fields.

Now how many cows do we have altogether across the fields? Let's use your careful counting fingers to count them out.

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

Let's represent those six cows using some counters.

Can you help me count six counters out.

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

They're on my six counters.

They represent the six cows.

Now how many groups can you see on the picture? The groups are represented by the number of fields.

Well done.

If you said three fields, you would be correct.

There are three fields on the picture and these are represented by my three pieces of coloured card.

One, two, and three.

Now we're going to have a look to see how many cows are in each field.

Let's have a look at the first field.

How many cows can you see in that field? Well done.

There are two cows in the first field.

Let's represent them using two counters on the first piece of coloured card.

One and two.

These are my two cows in the first field.

What about in the second field? The middle field? How many cows can you see there? That's correct.

There are two cows in the middle field.

Let's represent this using the counters on the coloured card.

One, and two.

And what about in the last field? How many cows can you see there? Correct.

There are two cows in the last field and there are two counters left over.

That must mean I have to put these two counters into the last field.

So can you see, there's a bit of a pattern emerging.

We have got three groups and each group has got two cows in them.

That means we have three groups of two.

Each of our groups are equal.

Now we can also represent the groups using pictures.

Here you can see my three fields.

Each group is represented by one of the fields in the picture.

I can also represent the cows using dots in each field.

So let's have a look at the first field.

I can see that there are two cows or two counters in my first group.

That means I can just draw two dots into my first field.

These two dots represent the first two cows.

In the middle field or in the middle square of coloured paper I can see that there are two more counters.

I'll just draw two more dots into the middle field.

They represent the two cows in the middle field.

And then in the third field, I can see that there are also two counters.

That is representing my two cows in the third field.

I'm going to draw in two dots to represent them on the picture.

Now it's your turn to have a go.

Using the resource cards from today's lesson, the concrete materials you have in front of you and drawing your own pictorial representation, have a go at representing the number of animals in each group.

Once you've had a go resume the video and we'll carry on with our learning.

Great work, everyone.

Let's have a look at one more example together.

So here represented by my counters and my coloured pieces of paper are my three groups.

Let's have a look at what we can see in each group.

How many counters do we have altogether first of all? Well, let's count them up to find the answer.

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

There are nine counters altogether.

They are representing nine sheep in the fields.

Now, something is going wrong with my groups.

I wonder if you can tell me what's happened? Well, I think you're right.

If you've said that the groups are unequal, then you would be absolutely correct.

In our first group, we've got one, two, and three sheep.

In our second group, we've got one and two sheep.

And in our third group, we've got one, two, three, and four sheep.

The numbers of sheep in each field are unequal.

What can we do to make that right? Great idea Elvis.

I think you're absolutely correct.

Elvis has said, if we take one of our counters or one of our sheep from this group and put it over here, then we'll have an equal number of sheep in each group.

Let's check to see, he is correct.

There are three sheep in this group, three sheep in this group and three sheep in this group.

The numbers of sheep in each group are equal now.

Thanks Elvis.

Now we can also represent those sheep using our pictures.

So here are my three fields.

Let's draw the number of sheep as dots in each field.

So in my first field, there are one, two, three sheep.

I'm going to draw them down as one, two, and three dots.

In my second field, there are three sheep.

And again, I'm going to draw them down as one, two, and three dots.

My three dots represent my three counters, which represent the three sheep.

And in the third field I've got one, two and three counters.

I can represent them using three dots in my picture.

There are my nine sheep represented by three sets of three dots.

I've had a fav learning for today everyone.

Now in lesson three, we will be exploring counting in groups of two to find the total.

Elvis and I are looking forward to seeing you there.

Bye for now.
