Lesson video

Hello, I'm Mrs. Kaylee and I'm going to help you with your lesson today.

So in today's lesson we're going to be skip counting in odds and evens.

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 skip count in odd and even numbers.

Here are our key words for today.

Can you repeat them after me? My turn, odd, your turn, my turn even, your turn.

My turn, skip count, your turn.

My turn, pairs, your turn.

Do you know what these words mean? So odd numbers are numbers that cannot be made of pairs.

They end in one, three, five, seven and nine.

An even number is a number that can be made of pairs.

They end in zero, two, four, six and eight.

Skip count means that we're going to count forwards or backwards, but not counting in ones, we're going to be counting in a different number.

Today we're going to be counting in twos.

Then pairs, that means things that come in twos, they come together in a group of two so we can have pairs of socks or shoes.

They come in twos, don't they? Here's the lesson outline for today.

We're going to be skip counting in odds and evens.

First of all, we will skip count using representations and then we will skip count and we'll be using a number line in the second part of the lesson.

Let's start on the learning.

Here are some children that are going to help us today.

We have Sam and Lucas.

Here's a number line.

Can you count along with the cubes and think about what do you notice? So we're going to start at zero and count in ones.

Can you count with me? Zero, one, two, three, four, five, six, seven, eight, nine, 10.

Can you see the cubes to represent each number? What do you notice? Sam has noticed that we are going up by one each time.

Lucas has noticed that we are saying odd and even numbers.

I wonder which ones are odd and which ones are even.

Let's count along with the cubes again and think about what do you notice this time? So we're going to start at zero.

We're going to count in ones, zero, one, two, three, four, five, six, seven, eight, nine, 10.

What do you notice this time? Can you see I've put some of the number shapes at the top and some are at the bottom.

I wonder which ones are at the top.

Sam said that odd numbers are shown at the top.

So which numbers are at the bottom? Even numbers are shown at the bottom.

Is that what you saw? What do you notice this time? We're going to start at two.

Let's see which numbers we're going to say two, four, six, eight, 10.

What do you notice about those numbers? Sam said these all have pairs so they are even, can you see the pairs of cubes in each number? Sam said we are going up by two each time.

Lucas said we are saying even numbers.

So we are missing out the odd numbers and we are saying the even numbers.

What do you notice this time? We are going to start at one, one, three, five, seven, nine.

What do you notice about those numbers? Sam has noticed that these do not have pairs, so they are odd.

We are still going up by two each time.

Lucas said we are saying odd numbers.

So can you see that we've missed out the even numbers and we're saying all the odd numbers.

Let's check your understanding.

Can you spot the mistakes? Here's a number line with some numbers on.

Sam said we are going up by two each time.

Lucas said we are saying even numbers.

Can you spot any mistakes? Pause the video while you have a look.

So I can see on the number line we've got two, five, seven, eight, and 10.

Are we going up by two each time? And are we saying even numbers? Sam has noticed that five and seven are not even numbers.

Lucas said they are both odd numbers.

It should be four and six.

Is that what you thought? So instead of five and seven it should be four and six.

So now is it correct? Are we going up by two each time and are we saying even numbers? We've got two, four, six, let and 10.

That's better.

Let's check your understanding again.

Can you spot the mistakes here? So look at the number line and the numbers marked on the number line.

Sam said we are going up by two each time.

Lucas said we are saying odd numbers.

Pause the video while you have a look.

Did you spot any mistakes here? So here we've got one, seven, five, three and nine.

Are we going up by two each time? Sam thinks three and seven are the wrong way round.

Lucas said they are both odd numbers but three comes before seven so let's swap those two numbers round.

That's better, isn't it? Now are we going up in twos and saying odd numbers, we've got one, three, five, seven and nine.

That's better.

Did you spot those? Here's a task for you to have a go at.

Can you complete the number lines with odd and even numbers and can you draw a picture to represent each number? So on the top number line, can you mark on even numbers? And on the bottom line can you mark odd numbers? So pause the video and have a go at your task.

How did you get on with your task? Did you complete the number lines with odd and even numbers and draw a picture to represent each number.

So here I've got on the top line some even numbers two, four, six, eight and 10.

And I've drawn number shapes to go with each number.

On the bottom line I've marked the odd numbers, one, three, five, seven and nine and I've drawn a representation for each of those odd numbers.

What did you do for yours? Let's move on to the second part of the lesson.

We're going to be skip counting.

Let's count along the number line.

We are going to start at one, one, two, three, four, five, six, seven, eight, nine, 10.

What do you notice about those numbers? So I can see some of them have got a purple circle and some are green.

Sam said, can you say the even numbers and whisper the odd numbers.

So let's have a go at this.

We're going to say the even numbers loudly and whisper the odd numbers.

So we're going to start by whispering the number one.

Are you ready? one, two, three, four, five, six, seven, eight, nine, 10.

Which numbers did we say loudly and which numbers did we whisper and what do you notice? Lucas has noticed that between two even numbers there is an odd number.

So we were saying odd, even odd, even odd even and so on.

Let's count along the number line again.

one, two, three, four, five, six, seven, eight, nine, 10, this time can you clap the odd numbers and whisper the even numbers? So let's start at one.

Is that an odd or an even number? It's odd.

So we're going to clap for the number one and whisper the even numbers.

Are you ready? One, two, three, four, five, six, seven, eight, nine, 10.

Which ones did we clap and what do you notice? We clapped the odd numbers this time, didn't we? Lucas has noticed that between two odd numbers there is an even number.

What do you notice this time, we're going to start at one.

This is odd.

So we've got one, two, three, four, five, six, seven, eight, nine, 10.

We've got even and odd numbers, haven't we? Sam said it goes odd, even odd, even odd and so on.

Lucas said odd and even numbers alternate.

That means it changes from one to the other.

Sam has noticed that between two even numbers, there is an odd number.

Lucas has noticed that between two odd numbers there is an even number.

Is that what you saw? We're going to start at zero and count in twos.

Zero, two, four, six, eight, 10.

Can you see the jumps of two that we've made? Sam said we are skip counting.

Lucas is asking can you see the jumps of two when we skip counting twos from zero? All the numbers after zero are even.

So the even numbers are two, four, six, eight, and 10.

Let's try starting at one and counting in twos.

So we're going to skip count starting from one, one, three, five, seven, nine.

Sam said we are skip counting.

Lucas is asking can you see the jumps of two when we skip counting twos from one? All the numbers are odd.

So one, three, five, seven and nine.

They're all odd numbers.

Let's check your understanding.

Here is a number track going from one to 10, which numbers are odd? Pause the video while you have a think, that's right, the blue ones are odd.

one, three, five, seven and nine.

Which numbers are even pause the video and have a think.

That's right, the yellow ones are even, two, four, six, eight, and 10.

Let's try skip counting in twos from the number one.

So we're going to start at number one and skip count.

So it goes one, three, five, seven, nine.

Let's try skip counting from the number two.

Can you do it with me? Two, four, six, eight, 10.

What do you notice? When you count in odds and evens, you count in jumps of two.

So we skip counting in twos.

Here are some even and odd numbers.

Can you see the even numbers at the top and the odd numbers at the bottom? Can you say the even numbers with me? Two, four, six, eight, 10.

Let's say the odd numbers.

One, three, five, seven, nine.

What do you notice? Lucas has noticed that two, four, six, eight and 10 are even, one, three, five, seven and nine are odd.

Let's check your understanding.

Sam and Lucas are skip counting.

Who has made his mistake? So Sam said one, three, five, seven, nine.

Lucas said two, four, six, eight, nine.

Has anybody made a mistake? Pause the video while you have a look.

That's right, Lucas made a mistake.

He should say two, four, six, eight, 10.

Let's check your understanding again.

Sam and Lucas are skip counting.

Sam is saying one, three, five, seven, nine.

Lucas is saying two, four, six, eight, 10.

Who is saying odd numbers and who is saying even numbers? Pause video while you have a think.

That's right, Sam was saying the odd numbers.

one, three, five, seven, nine.

And Lucas was saying the even numbers, two, four, six, eight, 10.

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

Can you see the number tracks here? Can you fill in the missing numbers? So the top track says two, four, 10 and the bottom track says one, seven, nine.

See if you can skip count and fill in the missing numbers and then work out which numbers are odd and which numbers are even.

Here's the second part of your task.

Can you fill in the missing numbers on the number line? So we are skip counting in groups of two.

Can you see the missing numbers there? And fill them in on the number line and then work out which numbers are odd and which numbers are even.

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

How did you get on with your tasks? Did you fill in the missing numbers on the number track? So the first number track says, two, four, six, eight, and 10.

The bottom number track is one, three, five, seven, and nine.

We skip counting in twos.

Which numbers are odd? Is the bottom number track, one, three, five, seven, and nine? Which numbers are even? That's the top number track, two, four, six, eight, and 10.

Is that what you thought? How did you get on on the second part of your task? Did you fill in the missing numbers on the number lines? So we are skip counting in groups of two.

The missing numbers on the top number line were one, three, five, seven, and nine.

The missing numbers on the bottom number line were two, four, six, eight, and 10.

Which numbers are odd? They're shown on the top number line, one, three, five, seven, and nine.

Which numbers are even they're shown on the bottom number line, two, four, six, eight, and 10.

How did you get on with that? We've come to the end of our lesson.

We've been skip counting in odds and evens.

This is what we found out.

Numbers that can be made out of pairs are even numbers.

Numbers that cannot be made out of pairs are odd numbers.

You can skip count using a number line.

When you count in odds and evens, you count in jumps of two, odd and even numbers alternate.

That means it changes from one to the other and back again, between two odd numbers, there is an even number and between two even numbers there is an odd number.

Well done everyone, see you next time.
