Lesson video

Hello there Maths friends, it's Mrs. Khaira and my marvellous mathematical maestro Elvis.

Now in this lesson, we are going to be practising counting in groups of five.

I wonder if you're ready to begin.

We certainly are.

Let's do this.

Now in this lesson, you're going to need the following items. You will require a bead string some counting objects, such as counters, and also you'll need a dice.

You will also require a copy of the activity sheets that are available in today's lesson resources.

Now, if you haven't got these things ready, please take a moment to go and collect what you need, and then resume the video.

Well, to start the lesson off, we're going to practise counting in fives.

On the table in front of me, I have a number line that starts at zero and works its way all the way to the number 20.

Now, when we count in fives, we don't count all the numbers, we count every fifth number.

and I have shown you where every fifth number is by putting a counter on top of it, like so.

So, let's practise reading these numbers, counting in fives from zero.

Are you ready? Off we go.

Zero, five, 10, 15, 20.

Well done everyone.

I wonder if you can help me say the numbers a little bit faster.

Zero, five, 10, 15, 20, brilliant.

I wonder if you can say the numbers in your quietest whisper voice.

Are you ready? Zero, five, 10, 15, 20.

Great work everyone.

How about we practise saying them in your loudest voices? Are you ready? Zero, five, 10, 15, 20.

Great work everyone.

We can also represent the numbers that we count in fives using some cubes.

So let's do that now.

Zero, we don't need any cubes here.

Five, I'm going to pop in a tower of five cubes.

10, I can add five more cubes in.

15, I can put a third group of five in.

And 20, here I can pop in my last tower of five.

Now, how many groups of five do we have altogether? I wonder if you can help me count them.

One group of five, two groups of five, three groups of five and four groups of five.

There are four groups of five.

Four groups of five are equal to 20.

And we can check that by counting up the number of cubes we have altogether.

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

Four groups of five are equal to 20.

So let's have a look at the talk task activity for today.

Here is an example of old McDonald's field.

Now old McDonald wants to group all of his animals into fives.

So let's see how many animals we have on our field at the moment.

So we've got two blue pigs.

We have got one yellow sheep and we have got a one purple cow.

Can you tell me how many animals there are altogether on old McDonald's field? Perhaps we can use our careful counting fingers to check.

Let's do this now.

One, two, three, and four.

There are four animals on old McDonald's field, but he wants to have five animals on each field.

We have still got some space on this field, so let's see if we can fill it up to make five animals on this field altogether.

Now, here are our choices.

We can either add in one, two or three orange ducks.

We could add in one or two green cockerels or we could add in one red horse.

So, let's pick one and see how many animals we have in the field altogether.

Let's pick the two green cockerels.

I'm going to move them together onto this spare spot.

Now, how many animals do we have altogether in old McDonald's field? Let's check to see if we've got five.

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

Oh dear, that's too many animals.

We're going to have to put the two green cockerels away.

Hmm, what happens if we add in the three orange ducks? Let's pop them into the farm and see.

So, I've put them into old MacDonald's field.

Do we now have five animals on this field? Let's check.

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

Oh dear, that's too many animals.

We might have to try another set.

Let's put these three orange ducks away.

Perhaps that means that we need to add our one red horse.

Well, let's pick him up and put him into the field.

Let's see what happens now.

I wonder if we've got five animals this time.

Let's check and see.

One, two, three, four, and five.

Yes, we've done it.

Old McDonald has got a group of five animals in his field.

So now it's your time to have a go at the activity.

In a moment, you're going to pause the video and you'll need to collect the activity sheet from today's resources that looks like the one on the screen in front of you.

With the help of a parent or carer, carefully cut out the five fields and cut each field into its four sections.

Then have a go rearranging each field so that you've got five animals in each one.

Altogether, you're looking for five groups of five animals.

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

Great work everyone.

Now let's have a go at practising counting groups of five using our bead string.

Now, I wonder if you have your bead strings in front of you.

Can you show me one group of five? If not, let's have a go together.

One group of five.

So I'm going to need to count out five beads.

Can you help me do this? One, two, three, four, and five.

Here is one group of five.

One group of five is equal to one, two, three, four, five beads.

How about if we make two groups of five? So I've already got one group of five.

Let's count out another five beads.

Can you help me do this? One, two, three, four, and five.

Here we have two groups of five.

Two groups of five are equal to how many beads I wonder? We can find out by counting them.

Let's do that now.

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

Two groups of five are equal to 10 bead, great work.

What about if I was to add another group of five? Let's count out another group of five beads now.

Can you help me do this? One, two, three, four, and five.

Here I have one, two, and three groups of five.

Three groups of five are equal to how many beads I wonder? Well, perhaps you can help me to count them.

Are you ready? Let's use our careful counting fingers.

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

Three groups of five are equal to 15 beads.

I think we're going to try one more group of beads.

Can we add one more group of five? Let's do this together now.

Count out five beads with me.

Off we go.

One, two, three, four, and five.

Now, we have one, two, three, and four groups of five.

Four groups of five are equal to let's count and check.

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

Four groups of five are equal to 20.

Great work everyone.

Now let's have a look at up independent activity for today.

You are going to need your bead string and you'll also need a die.

So I've got mine here, a one to six die.

So, old farmer McDonald would like to find out how many animals he has on his fields altogether.

Now the number of dots on the die that we roll is going to represent the number of fields.

And in each field, we know that they're going to be five animals.

So, let's have a go at the activity.

The first thing we're going to do is roll the die.

So let's do that now.

Cool, how many spots can I see on my die? I have rolled the number one, two, three, four, and five.

I rolled the number five.

That means that we need to find out how many animals there are on five fields.

So we're going to count out five groups of five.

Can you help me do this? Are you ready? Let's count our first group of five.

One, two, three, four, and five.

Our first group of five.

Let's do another one.

One, two, three, four, and five.

Two groups of five.

Remember we need to make five groups of five.

Let's do another one.

one, two, three, four, and five.

We have one, two, three groups of five.

We still need to make some more don't we? Let's do another.

One, two, three, four, and five.

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

I think we still need to make one more group of five to make five groups of five.

Let's do that now.

One, two, three, four, and five.

Here, we have our five groups of five.

One, two, three, four and five.

Now, let's find out how many animals there are altogether in our five fields.

So, five groups of five is equal to how many beads? Let's count and check.

You'll need to use your careful counting fingers here.

One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, and 25.

Five groups of five are equal to 25.

Great work everyone.

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

So, using your die and your bead string you're going to have a go at rolling the die to find out how many fields you need to find out groups of five for, and then make that number of groups of five.

Once you've done that, count to see how many animals there are altogether in old McDonald's fields.

Once you've had to go to the activity and maybe recorded your answers down, please resume the video and we'll carry on with the next part of our learning.

Great learning everyone.

Now, let's have a look at one last problem.

Now in my classroom today, there were 26 children present.

I have represented those 26 children using 26 cubes.

Well, let's have a look and see if we can count to make sure I've got the right number of cubes.

Have I got 26? Let's check together.

One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19 20, 21, 22, 23, 24, 25, and 26.

There are 26 cubes.

They represent my 26 pupils.

Now, I want to see if I can get my pupils into groups of five.

I want to know if there are going to be any leftover.

I wonder if you can help me to group them into fives.

We're going to count out fives and put each group on the side.

Can you help me make my first group of five? Let's do that now.

One, two, three, four, and five.

There's my first group of five.

Let's do that again.

One, two, three, four, and five.

I have two groups of five.

Let's do another one.

One, two, three, four, and five.

I have one, two, and three groups of five.

Let's see if I can make anymore.

One, two, three, four, and five.

Now I've got one, two, three, and four groups of five.

Can I make another one I wonder? Let's check.

One, two, three, four, and five.

Now I've got one, two, three, four, and five groups of five.

But look, I've got one leftover.

So, how many children have I been able to put into groups of five? Let's count in fives to find out.

Five, 10, 15, 20, and 25.

Five groups of five are equal to 25.

Fab learning for today everyone.

Now in Lesson 6, we will be exploring sharing objects into two equal groups, Elvis and I look forward to seeing you then.

Bye for now.
