Lesson video

Hello, my name is Robson.

In this lesson we are going to be ordering two or more numbers within 10.

We're going to start by recapping comparing quantities, which is something that we covered in one of our previous lessons.

Then we're going to work on ordering two numbers.

Then we're going to order three numbers within 10, and then your task will be to investigate some more ordering.

All you will need for this lesson is a number line to 10.

You might also find it helpful to have some things nearby like cubes, counters, or blocks that you could use to make the numbers, to compare them if you're finding ordering numbers a bit tricky.

Pause the video now to collect the resources that you need and when you're ready, press play.

We're going to start by recapping what comparing quantities looks like.

So I'm going to make a few different numbers using my cubes and I'm going to describe them using the words more than, and fewer.

So I'm going to stop by counting how many bowls there are in the picture.

Let me get my pointer.

There we go one, two, three, four, five.

There are five blue bowls.

I'm going to represent that with five blue cubes.

One, two, three, four, five.

Then I'm going to count how many chairs there are one, two, three, four, there are four chairs.

I'm going to represent that using some orange cubes.

To compare the quantities, all I need to do is put those two towers that I've made side by side.

So here they are standing next to each other.

I can see, because the cubes are the same size and they're starting at the same place.

I can look at them physically, one of them is taller, but also knowing that this is made up of five cubes and this one's made up of four cubes.

I know that there are fewer chairs than there are bowls and there are more bowls than chairs.

When we compare quantities, it can be helpful to make them, but today we're going to look at how to do that on a number line.

When we talk about ordering numbers, we will be asked to either order them from greatest to smallest or from smallest to greatest.

Today, we are going to be ordering them from smallest to greatest.

So every time I ask you to order some numbers, whether that's now or in your task later, I'm always looking for the smallest one first and the greatest one last.

Let's start by comparing these two numbers.

So, they do have cubes underneath them to help us in the beginning.

I've got the number three and I've got the number five.

I can also see on the screen is a number line and both of these numbers have been circled on the number line.

Our number line starts at zero and this one goes to 10 and the more jumps I do on the number line, the larger the number.

So I can see that the number three is smaller, here's the number three, because the number five has more jumps on the number line.

And if I look at the cubes underneath the number, there are more cubes there too.

So five is greater than three.

Five is bigger than three.

If I were to order these numbers from smallest to largest, I would put the number three first and then I would put the number five after.

I'm going to give you two numbers now and I'd like you to find them on the number line and have a go at figuring out which one is the smaller and which one is the larger of the two.

Here you have the number seven and the number three.

Find them on the number line and make them using some cubes if you think that would help you and try to figure out which one is the smallest and which one is the greatest.

You can pause the video now to work that out if you like.

I made the numbers, so I have seven cubes here and I have three cubes here and I also found them on the number line.

So using my pointer, here is the number three and here is the number seven.

Remember we started at the number zero and the more jumps along the number line that you have to do to reach a number, the greater that number is.

So I can see the number three is here and then further along the number line is the number seven.

I've also made them because that helps me too.

So here I have the number three and here I have the number seven.

I've ordered them from smallest to greatest, smallest to tallest, even with my towers while I'm looking at them like this.

So I can see that three is less than seven and seven is greater than three.

Now we're going to think about applying this skill to ordering three numbers.

It's very much the same skill, but instead we have three numbers to think about.

So we might need to find all three on the number line, or sometimes we like to start by finding the biggest and the smallest when there are three and then the other one, we should be able to find in the middle.

So jumping along the number line, I can see that when we start at zero, the first number that we come to.

So the one that involves the least jumps is the number three.

So here is the number three, that's first.

Then we have the number five, five is the next number that we come to when jumping along the number line.

So here is the number five, three, then five.

Then we keep jumping along the number line and we get to the number seven.

Here is the number seven.

So I have ordered them from smallest to biggest, least to most.

Three, five, seven, like I said before, if you are a bit stuck and you'd like to check, I sometimes like to find the smallest.

So I know the smallest number there is three and the biggest, I know the biggest number there is seven and so therefore five will fit nicely in between those two numbers, when I'm ordering three.

Let's try one more of those and this time it will be your turn to have a go.

Here you have the number of six, two and nine.

I'd like you to have a go at ordering them from the smallest to the greatest.

You can pause the video now, to work this out on the number line or using some cubes, if that helps and when you're ready, press play.

So, I made those numbers and I found them on the number line.

Can you tell me what number is first? What's the smallest number? The first one that you come to when you're jumping along the number line.

The smallest number is, let me grab my pointer.

So we start at zero, jump jump.

The smallest number is two.

I made two, here they are.

Then we keep jumping along the number line.

What number did you come to next? Next is the number six.

We've used the number two already.

Here we go, the smallest.

So we had to find out which one came next, nine or six.

We jumped along the number line until we found six, six is the next number.

Here I have six and here I have my two and I can see that two is definitely smaller than six.

So I keep jumping along the number line just to check that the next number, the greatest number of these three is nine.

So here is nine.

So I had two, six, nine.

If I was writing those as an answer on a piece of paper, I would need to put them in the right order.

So first I would write two, then I would write to six, then I would write nine.

Let's take a look at what that looks like.

Here are the numbers written in order two, six, nine, and you can see my working out on the number line too.

You can see where I've circled the different numbers as I hopped along and then in order, I come first to the number two, then to the number six and then last I get to the number nine.

Nine is my greatest number, two is my smallest and six is in the middle of those two.

Your task for today is going to be to do just this with some different numbers that I've supplied you.

You first need to figure out two numbers, ordering them from smallest to greatest.

Then you have a challenge of ordering three numbers and ordering them also from smallest to greatest You can use your number line to help you, you can also use some cubes, if you think that would support your understanding.

It's time now to pause the video, to complete your task.

When you're finished, press play.

I hope you enjoyed your task.

Before we finish today, we're going to play a quick game of I'm thinking of a number.

So I'm going to have a number in my head I'm going to give you some clues and they might involve things like greater than, less than.

And do you need to try and figure out what number I'm thinking of? So, my first number.

It is smaller, it is less than six, less than six, but it is greater than four.

Less than six, greater than four.

Use the number line to help you if you need.

What number do you think I'm thinking of? It's the number five.

Let's check that.

So I said that it was less than six, so I had to be jumps backwards from six, but greater than four.

So jumps forward from four.

So there's only one number that is less than six, but more than four, one less than five is four and one more than five is six.

Let's play one more time.

This time I'm thinking of a number that is more than seven, greater than seven, but less than nine, greater than seven, but less than nine.

Have a think.

Use the number line if you need.

What do you think my number was? It was the number eight.

Let's check by using the number line.

So it was more than seven.

So it had to jump on further than seven, greater than.

So we go this way, it could have been eight, nine or 10, but it was less than nine.

So here's the number nine, less than nine.

There's only one number that is greater than seven, but less than nine.

And that's the number, eight.

So one more than eight is nine, one less than eight is seven.

Of the two numbers I just gave you, eight was the greater number.

It was the bigger number that I was thinking of.

You can play games like greater than, less than, or you can challenge your talk partner or parent or carer to order two or three numbers using an number line.

You've done some fantastic learning today.

I hope that you've enjoyed learning about ordering two or more numbers, as much as I have.

Why not share your work with us? If you'd like to, please ask your parent or carer to share your work on Twitter, by tagging @OakNational and using the hashtag, Learn with Oak.

We'd love to see what you've been getting up to.

Don't forget to go and complete the quiz.

Thanks again for joining me and see you next time.
