Lesson video

Hello there everyone, it's Mrs.Khaira and my fantastic mathematical assistant Elvis.

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

Sounds exciting, doesn't it? Let's begin now.

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

So I'll be using counters, but you can use whatever you have at hand, and you'll also need the worksheets and items provided in today's lesson resources.

Now please ask a parent or carer to help you cut out the cards if you were using scissors.

So if you haven't got these things ready, please take a moment now to go and pause the video, collect what you need, and then resume your learning for today.

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

I wonder if you could remember which nursery rhyme it comes from.

That's right, It comes from Baa baa black sheep.

Now I wonder if you can help me to sing the first verse of the nursery rhyme in your best singing voices.

Are you sitting up straight? Are you ready? Alright, 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 your fantastic singing voices all the way from here.

Give yourselves a pat on the back if you joined in.

Now, I wonder if you can help me out with a question.

Can you see the balls of grey wool that I've put a red circle around in the big picture? I wonder if you can tell me how many balls of grey wall there are in that pile? You need to count very carefully.

So I'll give you a moment to have a look now.

Alright, let's see if you counted correctly.

Let's use your careful counting fingers to help me.

Are you ready? One, two, three, four, five, six, seven, eight, and nine.

There are nine balls of grey wool.

Now, Baa baa black sheep would like to share those nine balls of wool, between the dame, the master and the little boy.

Now, on the table in front of me, I've got three pieces of coloured paper.

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

And I want to see if I can share these nine balls of wool equally between them.

That means that they all need to have the same amount of balls of wool.

I'm going to represent my balls of wool using some coloured counters.

Can you help me to count out nine coloured counters? Off we go.

One, two, three, four, five, six, seven, eight, I'm going to put one here, and nine.

There are my nine coloured counters that represent the nine balls of wool.

Now I want to share them out equally between the three characters.

I'm going to do this by giving them one each, until all the counters as finished off.

So let's start with the dame.

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

One for the dame, one for the master, and one for the little boy.

One for the dame, one for the master, and one for the little boy.

I wonder if you can tell me, if I have shared the balls of wool equally? Well let's count and check.

The dame has got one, two, three balls of wool.

The master has got one, two, and three balls of wool.

And the little boy has got one, two, three balls of wool.

That means that I have shared my nine counters equally between the dame, the master and the little boy.

I have made three groups of three counters.

Alright, so let's have a look at another example.

Now, Baa baa black sheep's wool has become so popular that so many more people are interested in buying his wool.

At the marketplace today, there were five customers, who wanted to buy 20 bags of wool.

So, in my example, I have got five pieces of coloured paper, and these represent the five customers, The five people that want to buy his wool.

And I represented the 20 bags of wool using 20 counters.

Now, I want to make sure that the amount of bags of wool, that every customer gets is fair.

That means that they need to be equal, they all need to have the same amount of bags of wool.

So, can you help me to share out my counters equally between the five customers? Now we're going to give one counter to each of the customers one at a time until we finished all of the counters off.

Are you ready to help me? Alright, let's begin.

So we'll give one, to customer one, another one to customer two.

Let's give one to customer three, one to customer four, and one to customer five.

Now all of the customers have one counter each.

Let's give a second one to customer one, a second one to customer two, a second one to customer three, a second one to customer four, and a second one to customer five.

Now all of the customers have got two counters each.

So far, so good.

Let's keep going.

We're going to give a third counter to customer one, a third counter to customer two, a third counter to customer three, a third counter to customer four, and a third counter to customer five.

Everyone has got three counters each.

So far everything looks fair and equal.

Now let's give out the last few counters.

Let's see if we can do that equally.

The fourth counter goes to customer one, the fourth counter goes to customer two.

a fourth, counter to customer three, a fourth counter to customer four, and a fifth counter to customer four as well.

Is that right? Well, Elvis is shaking his head, he disagrees.

He thinks I've made a mistake.

Can you spot where I've gone wrong? That's right.

I've put an extra counter here on customer four's card.

So am going to move one over to customer five, like I should have done to begin with.

Now, I think that all of the customers have equal numbers of counters.

Let's check to see customer one has got one, two, three, and four counters.

Customer two has got one, two, three, and four counters.

Customer three has got one, two, three, four counters.

Customer four has also got four counters and customer five has also got four counters.

So, that means I shared my 20 counters equally between my five groups.

And each of the groups have got four counters each.

Now let's have a quick look at our talk task for today.

For this activity, you're going to need the number cards that are provided in today's lesson resources.

You'll also need some paper plates or some coloured pieces of card and you'll need some counting objects, so I've got my counters here to help me.

You'll also need your talk partner.

So here is Elvis ready to give me a hand.

Now, Elvis has picked one of the number cards from today's lesson.

He has picked the number 16.

The number 16 represents the number of bags of wool that I need to share.

And then there are four people's faces on the card.

That means I need to share 16 bags of wool between four people.

So, here are my four pieces of coloured card.

They represent the four people.

I'm going to count out 16 counters to represent the 16 bags of wool.

Let's do that together now, one, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, and 16.

There, are my 16 counters to represent my 16 bags of wool.

Now I want to see if I can share them out equally between the four customers.

Let's do this now.

Remember we want to make sure that the groups are fair and equal.

So the same number of counters in each group.

Let's go now.

So let's give one, to each of them first of all, three and four.

So each of the customers have got one bag of wool.

Let's do the same again.

One, two, three, and four.

Now each of the customers have got two bags of wool.

Let's go again.

One, two, three, and four.

Can you tell me how many bags of wool each of the customers have now? Shout the answer out at the screen.

That's right, they each have three bags of wool.

So let's carry on.

Let's do the last counters, one, two, three and four.

There, I have finished off all of my 16 counters.

Let's check to see how many they each get.

Well, this person has got one, two, three and four bags of wool.

This person has got one, two, three and four bags of wool.

This person here has also got four bags of wool.

And the last customer here has also got four bags of wool.

That means that I have shared my 16 counters equally between four groups.

Each group contains four counters.

So, in a moment it's your turn to have a go.

So you're going to press the pause button, collect all the resources you need for this activity and have it go with your talk partner.

And then once you both have a go at the activity, you can resume the video and carry on with our learning for today.

Great work, everyone.

Now let's have a look at developing our learning on a little bit more.

For today's independent tasks, you're going to need the activity cards, which are available in activity two of today's resources.

Here's one on the screen in front of you to show you what I mean.

Now, for this activity, we're looking at sharing a number of bags of wool equally between the number of people displayed on the card.

So, let's look at this card carefully.

I wonder if you can count out how many bags of wool there are on the picture card? You'll need to use your careful counting fingers to help you.

I'll give you a moment to have a go now.

Shall we have a go at counting them together? So, working from left to right let's count them out now.

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

There are nine bags of wool.

We want to share those nine bags of wool between the three people drawn on the card.

Between the dame, the master and the little boy.

So, I have represented the dame, the master and the little boy, using my story pieces of coloured card.

I'm going to represent the nine bags of wool using nine coloured counters.

Let's count them out now.

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

There are my nine counters.

They represent the nine bags of wool.

Now, let's share them out equally between the three characters.

Let's do this now.

So one for the dame, one for the master, one for the little boy.

One for the dame, one for the master, one for the little boy.

One for the dame, one for the master, and one for the little boy.

So, let's check what we've got.

The dame has got one, two and three counters.

She has three bags of wool.

The master has one, two, three counters.

He also has three bags of wool.

And the little boy has one, two, three counters.

He also has three bags of wool.

So let's have a go at filling in that statement.

Nine bags of wool sheared equally between three groups is equal to three, because each group received three counters.

So now it's your turn have a go.

in a moment, you can just pause the video and collect all the resources you need.

So once you've had a go at sharing out the bags of wool equally between the number of customers on each card, you can resume the video and we'll finish up our learning for today.

Right, super learning everyone for today.

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

I want to share my 15 bags of wool equally between my three customers.

The three customers are represented by the three coloured pieces of cars.

And my 15 customers are represented by my 15 counters.

Now, let's see if we can share out the 15 counters equally between my three customers.

Let's do this now.

So let's do one for each of my customers like so.

Two bags for each of my customers like so.

Three bags for each of my customers like so.

Four bags for each of my customers like so.

And a fifth bag for each of the customers like so.

So, let's check to see how many bags of wool, or how many counters each customer gets? Customer one gets one, two, three, four, and five bags of wool.

Customer two gets one, two, three, four, five bags of wool.

And customer three gets one, two, three, four and five bags of wool.

That means that my 15 bags of wool shared equally between three customers is equal to five.

That means that each of my three groups has been given five counters.

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

Because three groups with five counters in each of them, give us a total number of 15 counters altogether.

As ever, amazing effort for today, everyone.

Now, in lesson nine, we will be recognising the connection between sharing and grouping and solving some practical problems. Elvis and I look forward to seeing you then.

Bye for now.
