Lesson video

Hello there math geniuses, it's Mrs. Khaira, and it's Elvis, my fantastic mathematical helper.

Now in this lesson, we're going to be exploring sharing objects between equal groups.

I hope you're ready, because we certainly are.

Let's get cracking.

Now for this lesson, you're going to need the following items. You'll need some counting objects, such as counters or cubes, and you'll also need the number cards which are available in today's lesson resources.

Please ask a parent or carer to help you cut out the cards if you're using scissors.

Now, if you haven't got these things ready, please pause the video here, collect what you need, find a quiet spot to sit in and then resume our learning for today.

So let's have a look at our big picture for today.

Can you remember which nursery rhyme it comes from? That's right, it comes from "Baa, Baa, Black Sheep." Shall we have a go at singing the first verse together? Let's get your best singing voices ready.

On the count of three, one, two, three.

♪ Baa, baa, black sheep ♪ ♪ Have you any wool ♪ ♪ Yes sir, yes sir ♪ ♪ Three bags full ♪ ♪ One for the master ♪ ♪ One for the dame ♪ ♪ One for the little boy ♪ ♪ Who lives down the lane ♪ Great singing, everybody.

I could hear you all the way from here.

Now, here is a piece of wool from one of baa baa black sheep's bags of wool.

Now the dame and the master want to share this piece of wool equally between them.

That means they want the same amount.

So I'm going to have a go at cutting this into two equal pieces, so hopefully the dame and the master both get the same length of wool.

Wish me luck.

I have cut the wool into two pieces.

There's one for the dame, and one for the master.

Do you think these two pieces of wool are equal? Maybe you can give me a thumbs up if you think yes or a thumbs down if you think no.

Well, well done.

But all those people that put their thumbs down, you were correct.

These two pieces of wool are not equal, because they're not the same.

The dame is going to get a shorter piece and the master is going to get a longer piece.

That means that the two pieces do not have the same equal value.

Now, let's have a look at our new learning for today.

We are having a look at sharing equally between more than two groups.

So having a look at the big picture, you'll notice that the sheep has got four bags of wool.

There's two on the left and two on the right.

Now the sheep wants to take some of those bags of wool to the market, but only those bags that have enough wool to share equally between the dame, the master and the little boy.

So we're going to help him to do that.

Let's have a look at the set up on the table.

I've got some number cards and I've got three different coloured post-its to represent the master, the dame and the little boy.

Now, let's pick one of the number cards.

That will represent the number of balls of wool in one of the bags.

I think I might pick this one.

I have picked the number five.

So let's represent the number five now using some counters.

Let's count out five counters together.

One, two, three, four and five.

Now my counters represent the five balls of wool in one of the bags.

I want to try and share those out equally between the master, the dame and the little boy.

So I'm going to go ahead and give each one a ball of wool.

That's one for the master, one for the dame and one for the little boy.

Let's see if I can do the same again.

One for the master, one for the dame, but oh no! No more left for the little boy.

Well, let's see how many balls of wool each of them get.

The master gets one, two balls of wool.

The dame gets one, two balls of wool.

But the little boy only gets one ball of wool.

Do you think that they get an equal amount of balls of wool? That's right, if you said no, you would be correct.

The master and the dame have more balls of wool than the little boy.

That means that they do not all get an equal amount.

So now it's your turn to have a go.

You're going to need the number cards that are available in activity one of today's resources.

You're also going to need some counting objects like counters, and the help of your talk partner to give you a helping hand.

So Elvis is on the ready.

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

First of all, one of you is going to pick a number card.

I think Elvis is going to do that job for me.

Let's see what he has chosen.

Good choice, Elvis.

He's picked the number six.

Now it's my turn to have a go at representing the number six using my counting objects.

Can you help me to count six counters? One, two, three, four, five and six.

There are my six counters.

They represent the number six.

Now, we want to share the six counters out between three of the characters in the story.

So between the dame, the master and the little boy.

A look, there they are.

I'm going to try and do this equally by taking a counter at a time and sharing it one by one between the three characters until I have no more left.

Let's see if you can help me do this.

We're going to use our ordinal numbers to count out the counters.

So the first counter, I'm going to take that, and I'm going to give that to the dame.

The second counter, I'm going to take that, and I'm going to give that to the little boy.

The third counter is going to go to the master.

The fourth counter gets to the dame.

The fifth counter goes to the little boy, and the sixth counter goes to the master.

Is that right, Elvis? I think so.

So let's see how many each of those characters have received.

How many counters did they each get? So the dame, she has got one, two counters.

That represents the two balls of wool.

So the dame receives two balls of wool.

The little boy has got one, two counters.

He also receives two balls of wool.

And the master, he's got one, two counters.

That must mean he also gets two balls of wool.

I think that must mean, Elvis, that we have been able to share our six balls of wool, or our six counters, equally between the three characters, because they all get the same amount.

Once I've had a go, it's going to be Elvis's turn to have a go.

So in the moment, I would like you to press the pause button, and I'd like you to try this activity.

You're going to need counting objects and your number cards to help you.

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

So let's develop our learning on a little bit further.

For today's independent task, you are going to require the following things.

You're going to need your counting objects and you'll also need the number cards which are available in activity two of today's resources.

So I've picked the number 15.

Now I know that the number 15 can be shared between three, between the master, the dame and the little boy, but I want to help the sheep to find out how many each of them will receive.

So here are my 15 counters.

They represent the 15 balls of wool that we want to share.

Let's check that we've definitely made 15.

One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15.

So these are my 15 counters, representing the 15 balls of wool.

I'm going to start sharing them out equally between the master, the dame and the little boy.

I'm going to be giving them one each until we run out of counters to share.

Can you help me do this? So let's start here, shall we? So let's give one to the master, one to the dame and one to the little boy.

Let's give one to the master, one to the dame and one to the little boy.

Let's give one to the master, one to the dame and one to the little boy.

Let's give one to the master, one to the dame and one to the little boy.

Let's give one to the master, one to the dame and one to the little boy.

And there we have it.

We've shared the 15 counters out equally between the master, the dame and the little boy.

Now let's see how many each of them have got.

Let's start with the master.

He's got one, two, three, four, five counters, so he would receive five balls of wool.

The dame has got one, two, three, four, five counters also, so she also would receive five balls of wool.

And the little boy, I think you've guessed it, has got one, two, three, four, five counters, so he would also get five balls of wool.

That means that 15, shared equally between three groups, is equal to five.

15 shared equally between three groups is equal to five.

That's the same as saying that three groups of five are equal to 15.

Now it's your turn to have a go.

In a moment, you're going to pause the video and then using your counting objects and the number cards available in today's lesson resources in activity two, please have a go at sharing out equally between three groups, your counting objects, then have a go at using the modelled in the previous activity.

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

So let's have a look at one more example together before we finish off.

Here is an example where we want to share some bags of wool equally between three people.

We have the dame, the master, and we have the little boy.

Now, there are 18 bags of all there to share.

I've represented the 18 bags of wool using 18 counters.

Let's count them out together to make sure I've got the right amount.

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

These are my 18 counters.

They represent the 18 bags of wool.

And here are my three coloured pieces of card.

They represent the dame, the master and the little boy.

And what I'm going to share, my 18 bags of wool equally between the three characters.

Let's see how much they each get.

So I'm going to do this equally by giving one bag of wool to each character, and then starting again.

So the first bag of wool goes to the dame, then the master, then the little boy.

Let's do the next step.

One, two, and three.

One, two, and three.

One, two, and three.

And the last set of counters, two and three.

Okay, so I've shared out my bags of wool or my counters equally between the three characters.

Let's see how many they each got.

Let's have a look at the dame first of all.

She's got one, two, three, four, five, and six counters, six bags of wool went to her.

For the master, one, two, three, four, five, and six, six bags of wool for the master too.

And for the little boy, one, two, three, four, five, and six.

So each of the three characters received six bags of wool.

That must mean that 18, shared equally between three, is six, and also that three groups of six are equal to 18 all together.

Amazing work for today, everyone.

Now, in lesson eight, we will be exploring sharing quantities into equal groups.

Elvis and I look forward to seeing you then.

Bye for now.
