Lesson video

Hello, everyone, I'm Ms Cayley and I'm going to help you with today's lesson.

So today we're going to be explaining where six, seven, eight, and nine lie on a number line.

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

Here's the outcome of today's lesson.

I can explain how six, seven, eight, and nine lie between five and 10 on a number line.

So let's have a look at today's keywords.

Here are the keywords for today's lesson.

Can you repeat them after me? My turn, number line, your turn.

My turn, order, your turn.

My turn, one more, your turn.

My turn, one less, your turn.

Well done, do you know what these words mean? So a number line is aligned with the numbers written on in the correct order and the correct position.

Order means that we're going to put some numbers in order from smallest to largest or largest to smallest.

The order always stays the same.

One more means that there's a greater amount by one in a set and one less means that there's a smaller amount by one in a set.

Let's have a look at today's lesson outline.

Here's the outline of today's lesson.

We will be explaining where six, seven, eight, and nine lie on a number line.

First of all, we will order numbers and then we will be finding numbers on a number line.

So let's start on the first part of the lesson.

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

We've got Sofia and Jun.

Jun and Sofia are ordering the numbers from one to 10, here they've got some number cards with the numbers from one up to 10.

You could try this if you've got some number cards or you could write 'em on a piece of paper.

Jun is asking, "Which numbers will go near the start?" Sofia is asking, "Which numbers will go near the end?" You could try this with number cards.

So Jun and Sofia are ordering the numbers from one to 10.

Think about which numbers might go near the beginning and which numbers might go near the end.

Jun said, "I think one will be first "because it is the smallest." Sofia said, "10 will be last because it's the biggest." Do you agree? So they've put one at the beginning and 10 at the end.

I wonder which number's going to go next to them.

Jun said, "Two is one more than one, "so it will go next to one." Sofia said, "Nine is one less than 10, "so it would go before 10." Do you agree? Jun and Sofia have ordered the numbers.

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

Have they made any mistakes? Pause the video and have a look.

Jun said, "Four and five are in the wrong order." Do you agree? Sofia said, "Eight and nine are in the wrong order." Do you agree? So it should have been one, two, three, four, five, six, seven, eight, nine, 10.

Jun and Sofia are ordering some of the numbers, so they're going to go from one up to 10.

I wonder where they're going to put the number three and the number eight.

Jun said, "Three will be near one but not next to it." Do you agree? So Jun has put three on the number track.

Do you think he's put it in the right place? Sofia said, "Eight will be near 10 but not next to it." I wonder where she's going to put it on the number track.

She's put it near the number 10 but not next to it.

Do you think they've put them in the correct place? Yes, they have.

Jun and Sofia are ordering some other numbers now.

So they're going to put the numbers seven and nine on the number track.

Jun said, "Seven will be closer to five than 10." So Jun has put seven on the number track.

Has he put it in the right place? Sofia said, "Nine is one less than 10 "so it would be next to it." So Sofia's put nine next to 10.

Have they put 'em in the correct places? Yes they have, haven't they? Let's check your understanding, put these numbers in order and explain how you know and think about where they're going to go on the number track.

So pause the video while you have a think about this one.

What did you think about this one? Jun is looking at the number three.

He said, "Three is the smallest, "so it will be nearer to one than 10." I wonder if you can point to where it's going to go.

Jun's put it on the number track.

It's near to one but not next to it.

Do you agree? Sofia is looking at the number eight.

She said, "Eight is the largest, "so it'd be nearer to 10 than one." Can you point to where you think it might go? Sofia's put it here on the number track.

Do you agree? It's near to 10 but not next to it.

Jun is looking at the number five.

He said, "Five is between three and eight." I wonder if you can point to where you think it will go on the number track.

Jun has put it there on the number track.

It's near to the number three but not next to it.

Sofia said, "Five is nearer to three than eight." Do you agree? So the smallest one was three, the largest one was eight and five was in between.

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

Can you find some number cards from one to 10? Can you put your cards in order on the track? So starting with the smallest one and going all the way up to the largest one, 10.

When you've done that, take your numbers off and now pick three cards.

Starting with the smallest number, put the three cards in order, put them in the right position on the number track.

Use your reasoning to explain why you are right.

Here are some number cards that you could use.

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

How did you get on with your task? Did you order the numbers one to 10 correctly? So here we've got the numbers starting with the smallest, going from one all the way up to 10.

Jun said, "We put the numbers in the correct order." Sofia said, "One is the smallest and 10 is the largest." How did you get on on the second part of your task? Did you order three numbers correctly? So I've tried the numbers two, five and six and I've put them in the correct order and placed them on the number track.

Do you think I've put them in the right place and how do you know? So Jun said, "Two is less than five but not next to it." Sofia said, "Five and six will be next to each other." Jun said, "Two is one more than one," and Sofia said, "Six is one more than five." Do you think we've got 'em in the right place? We could check by counting all the numbers, even the ones that aren't there.

Do you want to point and check with me? One, two, three, four, five, six, seven, eight, nine, 10.

Yes, they were in the right place.

You might have tried some different numbers.

Here I've tried the numbers six, seven and nine and I've put them where they go on the number track.

Do you think I've put them in the right place and how do you know? Jun said, "Six and seven will be next to each other." Sofia said, "Nine is greater than seven but not next to it." Jun said, "Seven is one more than six," and Sofia said, "Nine is one less than 10." Do you think we've got them in the right place? Let's check by counting from the beginning.

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

Yes, they're in the right place.

How did you get on with yours and could you check that you got them in the right place? Let's move on to the second part of the lesson.

We'll be finding numbers on a number line.

Here's a number line.

We can place number on a number line, so we can start at zero and we can place the numbers, one, two, three, four, five, six, seven, eight, nine, and 10 on a number line.

Can you see they're all equally spaced apart? Jun said, "This number line starts at zero." Sofia said, "This number line goes up to 10." We've taken some of the numbers off the number line.

Which number is at the start of this number line? That's right, it's zero.

Zero goes before one.

Zero goes first because it is at the smallest.

Zero is one less than one.

Which number is at the end of this number line? It is 10.

Sofia said, "10 is last, it is the biggest.

"10 is one more than nine." Which number is in the middle of this number line? Jun said, "Five is in the middle of this number line." There it is.

Five is halfway between zero and 10.

Number lines from zero to 10 have five in the middle.

It is the same distance from zero and from 10.

There's five in the middle of the number line.

It's the same distance from zero and from 10.

We can use zero, five and 10 to place other numbers on the number line.

Jun said, "Zero, one, two, three and four "are all less than five." Sofia said, "Six, seven, eight, nine "and 10 are all greater than five." Where does two go on this number line? It goes there, it's more than zero but less than five.

Where does seven go on this number line? It's greater than five but less than 10.

How do you know? Jun said, "Two is between zero and five, "so it will be before five." Sofia said, "Seven is between five and 10, "so it will go after five." Jun said, "Two is closer to zero than five." Sofia said, "Seven is closer to five than 10.

"Seven is five and a bit.

"Seven is five and two more." Where does six go on this number line and how do you know? Where does nine go on this number line and how do you know? Here's six on the number line.

Jun said, "Six is between five and 10.

"Six is one more than five.

"Six is five and a bit." Here's nine on the number line.

Sofia said, "Nine is between five and 10.

"Nine is one less than 10." Jun thinks he has placed the number eight correctly on this number line.

Is he correct? There's the number eight and Jun said, "Eight goes here.

"Eight is nearer to five than 10." Do you think he's right? Sofia said, "Eight is nearer to 10 than five.

"Eight is five and three more." Who do you think is correct? Sofia said, "Eight needs to move closer to 10." Do you agree? There we are, that's better, isn't it? Now I can see that eight is five and three more and it's closer to 10 than to five.

Jun and Sofia are looking at the numbers between five and 10 on this number line.

Can you see five and 10 on the number line? Which numbers are going to go in between them? Here's the number six.

Six is nearer to five than 10.

Six is one more than five.

Here's the number nine.

Nine is nearer to 10 than to five.

Nine is one less than 10.

Here's the number seven.

Seven is nearer to five than to 10.

Seven is two more than five.

Here's the number eight.

Eight is nearer to 10 than to five.

Eight is two less than 10.

Let's check your understanding.

Can you spot the mistakes on this number line? Pause the video and see if you can see any mistakes and think about how do you know? Did you spot any mistakes on the number line? Jun said, "Six should be on the other side of five "because it is one more than five," so it should go there.

Sofia said, "Nine is one less than 10, "so it should be closer to 10," so it should go there.

Is that what you thought? Let's check your understanding again.

Can you spot mistakes here? Pause the video and see if you can see the mistakes and think about where the numbers should be.

Jun said, "Two and three are the wrong way round." Do you agree? Two is one more than three, isn't it? Sofia said, "Seven and eight are in the wrong order." Did you spot that one? Eight is one more than seven, isn't it? Here's a task for you to have a go at.

Can you draw a number line from zero to 10 and think about where each number will go? So you might want to use a ruler or something straight to help you get a nice straight number line and see if you can mark all of the numbers from zero to 10 and think about where you're going to put them.

Jun is asking a question, "How will you put the numbers in the right order?" Sofia said, "You could check on a number track." Jun is asking, "How will you position the numbers "in the right place?" Sofia said, "You could use cubes or fingers "to space the numbers out." Remember, you want them to be spaced out equally along the number line, so pause the video and have a go at drawing your own number line.

How did you get on drawing your own number line? Did you draw a number line from zero to 10? Here we've got all of the numbers from zero to 10 marked on the number line.

How did you know the right order? Sofia said, "I used one more and one less to help me." How did you put the numbers in the right place? Sofia said, "I used my fingers to space the numbers out." How did you get on with your number line? You can use your number line to help you with your numbers.

Well done, we've got to the end of our lesson.

Today, we were explaining where six, seven, eight, and nine lie on a number line.

This is what we found out.

We can order a set of one to 10 cards and find where the numbers six to nine sit in this group.

We can find one more and one less than the numbers one to nine.

We can decide where a given number is relative to one and 10.

A number line can be used to discuss the position of numbers relative to zero and 10.

Well done, everyone, see you next time.
