Lesson video

Hello, everyone.

How are you doing today? It's Mrs. Khaira and it's Elvis, my fantastical mathematical buddy.

Now in this lesson, we are recognising the connection between grouping and sharing, and we're going to practise that skill looking at some practical problems. Sounds exciting.

I can't wait to begin, so let's start now.

Now for this lesson, you're going to need the following items. You'll require some counting objects, so I'll be using counters, but you can use whatever you have to hand.

You'll also need the activity cards available in today's resources.

Now please ask a parent or carer if you need some help cutting out some of the cards, especially if you're using scissors.

Now if you haven't got these things ready, please press the pause button now, go collect what you need and then resume the video.

To warm our math brains up, let's have a look at some grouping.

Here are some animals on Old MacDonald's farm.

Let's count up to see how many animals are all together.

Can you help me do this? One, two, three, four, five six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16.

There are 16 animals all together on Old MacDonald's farm.

Now he wants to group them up into different numbers of animals.

Now we're get to pick a number card and we want to see if we can group the animals up into that number.

We want to know if there'll be any animals left over.

Let's pick a number card now then.

Hmm, perhaps we can try this number first.

I have picked the number three.

We're going to get our animals into groups of three and see if there are any left over.

Let's do this now.

One, two, and three.

That's one group.

One, two, and three.

That's two groups.

One, two, and three.

We've made three groups.

One, two, and three.

There's four groups.

One, two, and three.

There's five groups.

But look, there is one animal left over.

So we have made one, two, three, four, five groups of three animals, but there's one animal left over.

This time let's try making groups of two, right.

Can you help me put animals into groups of two? I'm going to need your counting skills.

Let's go.

One and two.

There's a group of two.

One and two.

There's a second group of two.

One and two.

Three groups of two.

One and two.

Four groups of two.

One and two.

Five groups of two.

One and two.

Six groups of two.

One and two.

Seven groups of two.

One and two.

That makes eight groups of two.

And look, there are no animals left over.

When we grouped 16 animals into groups of two, we get one, two, three, four, five, six, seven, eight groups of two and no animals are left over.

So let's have a look on new learning for saying.

Here is a picture of Old MacDonald's two fields.

Old MacDonald has been very lucky.

He has got six new horses.

I'm going to represent those six new horses with six counters, and there they are.

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

My six counters represent my six horses.

Now Old MacDonald wants to share the six horses equally between the two fields.

I wonder if he went to put all of his six horses into the first field, would that be fair? Maybe you can tell a talk partner are someone near you whether you think that would be fair.

I'm going to speak to Elvis.

Well, Elvis and I agree that we don't think it's very fair because there are all of the six horses in the first field and there are no horses in the other field.

That's not equal because there aren't the same amount in both fields.

We're going to have to have a think about how we can share the six horses out equally between the two fields.

Here are the six horses.

I have an idea, Elvis.

Perhaps we can take each horse or each counter at a time and place them into one of the two fields.

That way we might be able to share them out equally.

What do you think? I think Elvis agrees.

So let's start.

Let's take the first counter and I'm going to put it into the first field like that.

I'm going to take the second counter and I'm going to put that into the second field.

So now both fields have got one counter or one horse in them.

Let's take the third counter.

I think we should put that in the first field and the fourth counter should go into the second field.

Now doesn't that look a lot better? The first field has two counters and the second field has two counters.

So far, the amount of counters in both fields are equal.

So we've got two counters left.

I think we'll take the fifth counter and we'll put it into the first field like that.

That must mean that we'll take the last counter, number six, and put it into the second field.

Now I can see from looking at the picture that both of my two fields have got three counters in each.

That will mean that there will be three horses in each field.

That looks equal.

That's because two groups of three horses are equal to six.

Let's have a look at our talk task for today.

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

You'll need the activity one and activity two cards.

You'll also need a selection of counting objects, so I've got my counters.

And you need the help of your talk partner.

I've got Elvis here to give me a helping hand.

We're going to start by looking at the first card.

Now we need to be able to count up the number of animals we have on this card.

We've got one, two, three, four, five, and six.

There are six sheep on this card.

I am going to represent these six sheep using my counters.

So I'm going to put a counter onto each one.

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

There are my six sheep represented by my six counters.

Elvis is going to help me with the next part.

He has got the next card that we need to look at.

It matches the same animal that we have in our first card.

Elvis is going to help me explain the groupings that have been done in this second card.

We're going to use our counters again to help us do this.

So we're going to move our counters from this card to the other, looking at the groups that we create in the process.

I can see that the first group here has got one and two sheep in it.

I can see here the second group has got one and two sheep in it.

I can see that the third group here has also got one and two sheep in it.

Elvis is going to have a good look at what we've just done and he is going to explain to me what we have done in this picture.

Elvis has just told me that we can explain this picture in two ways.

We can say that our six sheep have been shared equally between three groups.

Six shared between three groups is equal to two because there are two sheep in each group.

Elvis is also very clever.

He has just spotted that we can also say something else.

We could also say that three groups of two counters each are equal to six.

Now it's your turn to have a go.

With your talk partner, you're going to need the cards that we've used in this activity.

Now it's your turn.

With your talk partner, you're going to need to get a set of the cards that we've used in this activity from the resources today.

Have a go at grouping the animals and then explaining to your part how you've grouped and how you've shared the counters out.

Once you and your partner have had a go, you can resume the video and we'll carry on with our learning.

Let's have a look at moving our learning on a little bit more.

We're going to carry around exploring the relationship between grouping and sharing.

For this activity, you're going to need the activity three worksheet that's available in today's resources.

I have got one of the cards here on the desk in front of me.

Let's have a look at what the picture shows.

All together, how many pigs can you see in this image? We can count them up to check.

I can see that there are one, two, three, four, five, and six pigs.

I've represented those six pigs using six counters.

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

Now I can see that the pigs have been grouped into two equal groups.

I'm going to represent those two groups using two pieces of coloured paper.

Here's my first group and here is my second group.

Now I want to share my six counters equally between the two groups.

So let me do this now.

I'm going to put one counter here and one counter there.

One counter here and one counter there.

One counter here and one counter there.

Let's have a look at what's happened.

In my first group, I can see that I've got one, two, and three counters.

That's the same as the picture.

In the first group, there are one, two, and three pigs.

In the second group, I can see one, two, and three counters.

That's the same as the second group.

I've got one, two, and three pigs here.

I shared six counters equally between two groups.

How many counters are there in each group? That's right.

There are three counters in each group.

Now we can use that information to help us fill in this first sentence.

Six shared equally between hmm is equal to hmm.

Here are my six counters and I shared them equally between two groups.

So I'm going to put the number two into that first box.

Six shared equally between two is equal to how many counters were in each group? Can you shout the answer out at the screen? That's right.

There were three counters in each group.

So six shared equally between two is equal to three.

Now we can also create a sentence that looks at groups.

Mm groups of mm are equal to hmm.

So how many groups do we have in total all together? Can you shout the answer out at the screen? That's right.

We've got two groups and how many are there in each group? Shout the answer out at the screen again.

Great work.

We could say that two groups of three counters are equal to or how many counters were there all together? We can count them up just to remind ourselves.

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

Two groups of three counters each are equal to six.

Now it's your turn to have a go.

You'll need activity sheet three from today's resources and some counting objects.

Perhaps you can use some cubes or some counters to help you.

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

Let's have a look at the last bit of our learning for today.

Here are 12 animals that are on Old MacDonald's farm.

Now Old MacDonald would like to put these animals into fields but he wants the same number of animals in each field.

He's left it up to us to decide whether we want to group the animals into equal numbers or share the animals into equal numbers.

If we wanted to group the animals into equal numbers, we would need to identify a number of animals that we would like to put into each group.

So let's pick a number.

Let's try the number six.

Now let's see if we can group the animals into sixes.

We want to see whether there are any animals left over.

Let's do this now.

Can you help me count out groups of six animals? One, two, three, four, five, and six.

Here is one group of six animals.

I wonder if we have enough animals for another group of six? Let's check now.

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

Here is a second group of six animals.

So we were able to group our 12 animals into two groups of six.

Now let's try sharing the animals instead.

If we wanted to share the animals, we would need to know the number of fields we have to begin with.

Let's assume that we have one, one, and two fields.

We want to share our animals into two fields.

So we would have to share them out equally by placing one animal into each field until we've run out of animals.

We'll put one animal here and one animal in this field.

One animal goes here and one animal goes here.

One animal goes here and one animal goes here.

One animal goes in the green field and one in the orange field.

One in the green field and one in the orange field.

One in the green field and one in the orange field.

So how many animals do we have in each field? We've got one, two, three, four, five, and six animals in the green field.

And we've got one, two, three, four, five, and six animals in the orange field.

By sharing our 12 animals between two fields, we've been able to make two groups of six.

So we have been able to group and share.

Perhaps you can investigate the differences between sharing and grouping.

Maybe using your very own set of animals to find out the answers.

Great work for today, everyone.

Elvis and I are so proud of you.

Now in lesson 10, we'll be consolidating our learning of grouping and sharing.

Elvis and I are looking forward to seeing you then.

Bye for now.
