Lesson video

Hello, maths friends.

How are you all doing today? It's Mrs. Khaira and for this unit I've got a brand new friend to help me.

This is Elvis, everybody.

He is a sheep.

He is very small, but he is very clever and he is going to be my partner in today's activities.

Now in this lesson, we are exploring the concept of equal groups.

I hope you're ready to begin because we are definitely ready to start.

Let's get going.

Now for this lesson, you're going to need the following items. You'll need some counters and you'll also need Old MacDonald's farm as is available in today's lesson resources.

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

Now let's have a look at our big picture for this unit.

You might recognise this picture from a nursery rhyme that you might sing, this is Old MacDonald's farm.

Now I'm going to need you to look really carefully at the big picture and help me to answer some questions.

It might help to put your detective glasses on because you're going to need to look really carefully.

Are you ready to have go? All right, well, can you see the yellow field in the middle of Old MacDonald's farm? Great work, everyone.

I wonder if you can tell me how many barns you can see in the yellow field? Have a good look now.

Well, I think Elvis might have an answer to the question.

I wonder if you can use your careful counting fingers to help me check the answer.

One, two, and three.

There are three barns in the yellow field.

Well done everyone.

Here's another question.

Look really carefully at the yellow field, how many trees can you see in that field? Have a moment to have a look now.

Well, I wonder if you got the answer as quickly as Elvis and I did.

Let's check again using our careful counting fingers.

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

There are six trees in the yellow field.

Great work, everyone.

This time, I'm going to need you to look really carefully.

I wonder if you can see how many horses there are in that yellow field.

Have a good look now.

Elvis knows for sure.

Are you ready to check? One, two, and three.

There are three horses in the yellow field.

The number of horses and the number of barns are equal.

Great counting, everyone.

So you might know the nursery rhyme 'Old MacDonald had a farm'.

Shall we sing the first verse together? Are you ready? ♪ Old MacDonald had a farm ♪ ♪ Ee i ee i o ♪ Great singing everyone, I could hear you all the way from here.

Now, this is Old MacDonald's farm and he has got five fields.

Let's count them out together.

One, two, three, four, and five.

Now Old McDonald has also got 20 cows and he wants to arrange the cows into his fields.

We're going to help him to count out and arrange the 20 cows into his field.

Are you ready to help me count? Use your best counting voices and your counting fingers to help you.

Let's go now, one, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, and 20.

There are Old MacDonald's twenty cows and he has arranged them into his fields.

So there are five fields That means that there are five groups.

Now I wonder if you can tell me, are the number of cows in each group equal? That means are they the same, have a look now.

Well, let's have a look carefully together.

We can see that the lilac field and the turquoise field, they have both got three cows each in them.

I can see that the pink field has got four cows inside it and the purple field and the green field have got five cows in each of them, so that means that the number of cows in each field is unequal, they're not the same, but we know all together that we have arranged Old MacDonald's 20 cows into the five fields.

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

Here is Old MacDonald's farm, here are his five fields.

One, two, three, four, and five, and here are Old MacDonald's 20 cows.

I have represented them using 20 counters.

Let's see if I've counted out the number of counters correctly.

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

Now, we are going to have a go at arranging the 20 cows onto the five fields.

How you choose to do this is up to you.

I'm going to show you one way in which you might choose to arrange your cows.

So I'm going to start with the first field here.

I'm going to put in one, two, three, four, and five cows into that first field, one, two, three, four, and five.

Into the second field, I'm going to pop in one, two and three cows, one, two, and three.

Into the third field here, I'm going to put in one, two, three, four, and five cows again.

Into my fourth field, I'm going to put it in one, two, and three cows and into my last field, field number five, I'm going to put in one, two, three, and four cows so I have arranged my cows into the five fields like so.

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

So perhaps with a talk partner, have a go at arranging your 20 cows into the five fields then once you're done, tell your partner how you have arranged your counters.

Once you've had a go, switch over and then when you both had a go, please resume the video and we'll carry on with our learning.

Well, I hope you had a good go at that activity and I wonder how many different ways you found of arranging the 20 cows.

Let's look at this example, just here.

I wonder if you can help me to count out the number of counters on each field.

We know that we have our five fields and they represent the five groups.

One, two, three, four, and five.

Let's have a look at the first field.

Let's count how many counters I've put onto the first field.

We have one, two, three, four, and five.

They represent the five cows on the first field.

What about on the second field? One, two, three, and four.

There are four counters on this field.

On the third field, how many counters can you see? One, two, three, and four.

There are four counters on our third field.

On the fourth field, there are one, two, three, four, and five counters representing five cows, and on the last field, there are one and two counters representing two cows.

I wonder if you can tell me whether our five groups are equal or unequal? Perhaps you can shout the answer out to the screen.

That's right, they are unequal that's because each group has a different number of cows in it.

This time, Old MacDonald has decided that he wants the same number of cows in each field.

Let's see if we can have a go finding out what number of cows we need to put on each field.

Let's take our counters away and let's try again.

Well, this time, I think I'm going to put three counters onto my first field, one, two, and three.

I think I'm going to need to put the same number of counters on the next field, because if Old MacDonald wants an equal number on each field, that means I need to have the same number on each of my groups.

So let's put three counters here as well, one, two, and three.

I'm going to need to put three counters at each of my other fields, let me do that now.

One, two, and three, one, two, and three, and one, two, and three, oh dear, that doesn't quite work.

Look, we still have got some counters leftover, that must mean that we need more than three cows on each field so now it's your turn to have a go.

How about you go perhaps with your talk partner? Rearrange your 20 counters onto the five fields in order to create five equal groups.

I wonder how many counters you might need to use on each field? Once you've had a go at this activity, you can resume the video and we'll carry on with our last bits of learning for today.

Great work for today, everyone.

Elvis and I are so proud of how you've been getting on.

Now, to finish off, we're going to have a look at one more question.

This time Old MacDonald has 15 cows and he wants to arrange them onto his five fields.

Let's see how he's done it, can you help me to carefully count out using your careful counting fingers, the 15 cows? Let's go now, one, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, and 15.

Great counting, everyone.

There are Old MacDonald's 15 cows.

Now, I have a question for you, I wonder if you can look very carefully at each of the groups on the screen, in each of the five fields has Old MacDonald put an equal number of cows in each? Have a look now to see if you can find the answer.

Well, I think we can check to see how many cows are in each field to find out if the number is equal with each group.

Let's check now so in the first field, there are three cows, one, two, and three.

In the second field, there are three cows again, one, two and three.

In the third field, if you look really carefully, you'll see there are three cows again, one, two, and three.

In the fourth field, there are also three cows and in the fifth field, there are also three cows, that marks me and Elvis that Old MacDonald had arranged his cows into equal groups.

There are five groups of three cows each.

Great work, everyone.

Now in lesson two, we'll be practising counting in equal groups and then adding them together, Elvis and I are looking forward to seeing you then, bye for now.
