Lesson video

Hello, I'm Mrs. Cayley and I'm going to be your teacher today.

So, in today's lesson we will explain that numbers can represent the amount of objects in a set.

So, let's have a look at today's lesson outcome.

Here's the outcome of today's lesson.

So, by the end of the lesson you'll be able to do this.

I can recognise how many objects are in a small set without counting them.

So, this is also called subitising, so we'll practise our subitising skills today.

Here are the key words for today's lesson.

You might have seen these before.

The first one is count.

Can you repeat that after me? My turn, count, your turn.

The second word is subitise.

Can you repeat that after me? My turn, subitise, your turn.

Then we've got the numbers zero to ten.

Can you repeat those after me? So, my turn, zero, your turn.

My turn, one, your turn.

My turn, two, your turn.

My turn, three, your turn.

My turn, four, your turn.

My turn, five, your turn.

My turn, six, your turn.

My turn, seven, your turn.

My turn, eight, your turn.

My turn, nine, your turn.

My turn, ten, your turn.

Well done, we'll be practising all the numbers from zero to ten today.

Let's think about the keywords and what they mean.

Count means that we say the numbers in order to find out the total amount in a set.

Subitise means that we try to see the amount without counting, so we instantly know or recognise how many objects were in a set without having to count them, and we practise these skills today.

Let's look at the lesson outline.

So today, we will explain that numbers can represent how many objects there are in a set, and we'll start off by counting and then we'll move on to subitising.

Let's start on the first part of the lesson.

Here are some children that will help us today.

We've got Aisha and Lucas.

Let's practise saying the number words in order.

Can you say them along with me? One, two, three, four, five, six, seven, eight, nine, ten.

I wonder if you can hold up your fingers while we say them? Are you ready? Should we try it again? Get your fingers ready.

One, two, three, four, five.

That's one hand done.

Six, seven, eight, nine, ten.

Both hands, well done.

Let's try saying the number words in order again.

This time we'll see some cubes to match the numbers.

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

Can you see the cubes to go with each number? It's like a staircase.

They're getting bigger each time.

Do you know some counting rhymes? Let's sing this number rhyme together and watch the raindrops as they fall.

You might have heard this song before.

It goes like this.

♪ One little, two little, three little raindrops ♪ ♪ Four little, five little, six little raindrops ♪ ♪ Seven little, eight little, nine little raindrops ♪ ♪ Ten little raindrops falling down ♪ Can you sing it again with me? Let's put our fingers up as we count the raindrops.

Are you ready? Get your fingers ready.

♪ One little, two little, three little raindrops ♪ ♪ Four little, five little, six little raindrops ♪ ♪ Seven little, eight little, nine little raindrops ♪ ♪ Ten little raindrops falling down ♪ Well done.

Do you know any other counting rhymes? I know a counting song about potatoes.

It goes like this.

♪ One potato, two potato ♪ ♪ Three potato, four ♪ ♪ Five potato, six potato ♪ ♪ Seven potato, more ♪ ♪ Eight potato, nine potato ♪ ♪ Ten potato all ♪ ♪ Ten potatoes in the potato store ♪ Can you sing it along with me? You might want to count on your fingers as we sing the song, or you can make potatoes with your hands and put them in a pile.

So, let's try it again.

Are you ready? Start with one potato.

♪ One potato, two potato ♪ ♪ Three potato, four ♪ ♪ Five potato, six potato ♪ ♪ Seven potato, more ♪ ♪ Eight potato, nine potato ♪ ♪ Ten potato all ♪ ♪ Ten potatoes in the potato store ♪ Here's the potatoes again.

Shall we count them one more time? One potato, two potatoes, three potatoes, four potatoes, five potatoes, six potatoes, seven potatoes, eight potatoes, nine potatoes, ten potatoes.

I wonder if you've got some real potatoes that you can count.

I know another counting song called "1, 2, 3, 4, 5, once I caught a fish alive".

Do you know this song? In the song we do not count objects.

How could we represent the numbers in the song? Lucas thinks we could use our fingers as numerals.

Let's have a go at singing the song and join in with your fingers.

Are you ready with your first finger? ♪ 1, 2, 3, 4, 5, once I caught a fish alive ♪ ♪ 6, 7, 8, 9, 10, then I let it go again ♪ ♪ Why did you let it go ♪ ♪ Because it bit my finger so ♪ ♪ which finger did it bite ♪ ♪ This little finger on my right ♪ Well done, that's a nice song, isn't it? Do you know any other counting songs? Remember, our fingers can be used as numerals to represent the numbers in our count.

Let's practise counting with our fingers.

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

Well done.

Do you know any other counting rhymes? Perhaps you could sing them with your friends.

Aisha knows a song called "One, two, buckle my shoe".

Lucas knows a song called "Here is the beehive".

Which songs do you know? Now, we have practised counting.

Let's count the apples.

Can you count the apples with me? One apple, two apples.

There's the number 2.

There are two apples on the plate.

Can you hold up two fingers to show two apples? Let's count the oranges.

Can you count them with me? One orange, two oranges, three oranges, four oranges.

There's the number 4.

There are four oranges on the plate.

Can you hold up four fingers? Let's check your understanding.

How many lemons are on the plate? Can you count them on your fingers? That's right.

One lemon, two lemons, three lemons.

There are three lemons on the plate.

Let's check your understanding again.

How many bananas are on the plate? Can you count 'em on your fingers? That's right.

One banana, two bananas, three bananas, four bananas, five bananas.

There are five bananas on the plate.

We can count any object.

Wonder how many pieces of fruit there are here? How many bananas are there? Can you count the bananas? One banana, two bananas.

There are two bananas.

How many potatoes are there? Can you count the potatoes? There are zero potatoes.

I didn't put any potatoes on that picture.

How many oranges are there? Can you count the oranges? There are one, two, three oranges.

There are three oranges.

How many apples are there? Can you count the apples? One apple.

There is one apple.

How many lemons are there? Can you count the lemons? One lemon, two lemons, three lemons, four lemons.

There are four lemons.

We can count any object to find the total.

How many pieces of fruit are there in the whole? Let's count all of the pieces of fruit.

Can you count them with me? You might want to point to the fruit as we count them or use your fingers as we count along.

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

There are 10 pieces of fruit altogether.

Counters can be used to represent the pieces of fruit.

So, we could put counters on top of each piece of fruit as we count them.

Let's count 'em together.

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

There are 10 counters altogether.

So, there are 10 pieces of fruit altogether.

It can be easier to count objects when they're in a line.

So, let's put the counters in a line.

Can you count them with me? 1, 2, 3, 4, 5 6, 7, 8, 9, 10 counters altogether.

There are 10 counters altogether.

Let's check your understanding.

Aisha says, "There are 4 counters in total." Is she right? Pause the video, and think about whether she's right or not.

She wasn't right.

There are not four counters there.

Let's count them together and see how many there are.

One, two, three, four, five counters.

There are five counters in the set.

Lucas says "There are 5 counters in total." Is he right? Pause the video and think about whether he's right or not.

Yes, Lucas was correct.

Let's check together.

One, two, three, four, five counters.

There are five counters in total.

Here's a task for you to have a go at.

First of all, can you count the fruit and write the total amount on each plate? So, on the first plate, can you count how many apples there are, then count how many oranges there are, and then count the lemons? And write the total amount for each plate.

Here's the second part of the task.

Can you count the fruit? So, we've got some apples, oranges, lemons, bananas and potatoes.

See if you can write down how many of each piece of fruit there are.

And then finally, find out how many pieces of fruit there are altogether.

You can use your fingers or you could use counters to help you check.

So, pause the video and have a go at your tasks.

How did you get on with your task? Did you count the pieces of fruit and write the total amount for each plate? So, on the first plate we had some apples.

Should we count the apples together? We've got one apple, two apples, three apples, four apples, five apples.

There are five apples altogether.

Now, let's count the oranges.

Can you count them with me? One, two, three, four oranges.

There are four oranges on the plate.

Let's count the lemons together.

One lemon, two lemons, three lemons.

There are three lemons on the plate.

How did you get on with that one? This was the second part of your task.

Did you count the fruit? So, let's see how many pieces of the fruit there are.

There are two apples.

I can see one, two apples.

There are four oranges.

I can see one, two, three, four oranges.

There is one lemon.

I can see one lemon near the top.

There are three bananas.

One, two, three bananas.

There are zero potatoes.

And altogether there are 10 pieces of fruit.

Let's check by counting all of the fruit.

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

There are 10 pieces of fruit altogether.

Let's start on the second part of our lesson.

We will be subitising.

This means that we're going to try to see the amount without counting.

Subitising is when we know how many there are without counting.

Aisha is asking, "Can you see how many there are without counting?" Lucas said, "I know there are 2 counters." Did you know that was two? Can you see how many there are without counting here? Lucas said, "I know there are 3 counters." Is that what you thought? Subitising is when we know how many there are without counting.

Can you see how many fingers there are without counting? Lucas said, "I can see 5 fingers held up." "Can you see how many there are without counting?" "I can see 4 fingers held up." Let's check your understanding.

How many can you see? "Can you see how many there are without counting?" That's right, there are three.

"Don't count, see the amount." How many? "Can you see the amount without counting?" That's right, there's one.

"Don't count, see the amount." "Can you see how many there are without counting?" There are five, that's right.

"Don't count, see the amount." "Can you see how many there are without counting?" That's right, two.

"Don't count, see the amount." "Can you see how many there are without counting?" That's right, four.

"Don't count, see the amount." Let's see if you can subitise again.

How many dots can you see? Four dots.

"How do you know?" Lucas said, "I can see 4 dots in a square shape." Did you see a square shape? How many this time? That's right, five dots.

"How do you know?" Lucas said, "I can see 4 dots around the edge and 1 in the middle." So, we've got four dots in a square and one in the middle, that makes five.

How many? That's right, three dots.

"How do you know?" Lucas said, "I can see 3 dots in a line." How many? That's right, two dots.

"How do you know?" Lucas said, "I can see a line of 2 dots." How many? That's right, six dots.

"How do you know?" Lucas said, "I can see 3 dots and 3 dots." Three in a line and another three in a line.

"How many dots?" That's right, 4 dots.

"How do you know?" Lucas said, "I can see 4 dots in a square shape." "How many dots?" That's right, five dots.

"How do you know?" You've seen that pattern before? It looks like 5 on a dice.

Let's check your understanding.

Which image shows 4? Point to the right image.

That's right, four dots.

Which image shows 3? Point to the right image? That's right, three dots on the dice.

Which image shows 5? That's right, five fingers on one hand.

How many dots here? Four dots.

"How do you know? Lucas said, "I can see 2 dots and another 2 dots." How many this time? There are 3 dots.

"How do you know?" Lucas said, "I can see 2 dots and another dot.

It's almost like a triangle in shape." Can you see a triangle shape? How many dots this time? There are 5 dots.

"How do you know?" Lucas said, "I can see 3 dots and 2 dots." We can subitise things in our environment.

So, you could have a look around you and see if you can quickly see how many there are without counting.

How many chicks are at the farm here? That's right, there are 5 chicks at the farm.

"How do you know?" Lucas said, "I can see 3 chicks and 2 chicks." That makes five chicks.

How many this time? There are 4 chicks.

"How do you know? Lucas said, "I can see 3 chicks and 1 chick." That makes 4 chicks.

"There is one fewer than last time." Last time we had five, didn't we? And one must have hopped away.

How many this time? Still 4 chicks.

"How do you know?" Lucas said, "I can see 2 chicks and another 2 chicks." One chick hopped across.

These eggs will hatch soon.

How many chicks will there be? Can you subitise the eggs in the nest? There are five eggs in the nest.

We can count the chicks to check that we have subitise correctly.

Let's count the chicks as they hatch outta the eggs.

1 chick, 2 chicks, 3 chicks, 4 chicks, 5 chicks.

"There are still 5 even though they're in a different arrangement." There were five eggs and now there are five chicks.

Let's check your understanding.

Which group of birds matches the number of eggs? Can you subitise the number of eggs in the nest? There are four eggs in the nest.

So, which group of chicks matches the eggs? That's right, there are four eggs and there are four chicks.

Which group of birds matches the number of eggs now? There are three eggs in the nest and there are three chicks over there.

Here's a task for you to have a go at.

Can you subitise to find the total of each group of objects? Record the numerals, including the number words that represent each number.

So, I've done the first one for you.

We had three pieces of fruit, and I've written the word and written the numeral.

Can you subitise the other groups and write down the numerals? Here's the second part of your task.

Can you use drawings to show these numbers? When you've drawn them? You can cut up the cards and test a friend with their subitising skills.

So pause the video and have a go at your tasks.

How did you get on with your task? Did you find the totals and then record the numerals that represent them? So, we had three pieces of fruit.

We had four counters, and we had five cakes.

Here's the second part of your task.

What did you draw to show the numerals? I've drawn some black counters here.

We've got one black counter, we've got zero counters, and four counters.

Did you cut up the cards and test a friend's subitising skills? We've got to the end of our lesson.

Well done, everyone.

So, numbers can represent how many objects there are in a set.

We can count objects to find the total amount.

The last number we count tells us the total amount of objects.

For small sets, we can subitise to find the total amount instead of taking the time to count them all.

So, you can practise your counting and your subitising.

Well done, everyone.

See you soon.
