Lesson video

Exploring numbers with a difference of one to two, using a number line.

Hello, everybody I'm Miss Sidhu, and I'm working with Mrs. Bramble to help you with your math today.

Now in this lesson, you will be comparing two sets of objects and finding out the difference between them using a number line.

Now let's get started.

In today's lesson, you will be comparing numbers, finding the difference using a number line, an independent task, and end of lesson quiz to see everything that you have learned.

In the lesson today, you will need a pencil and a paper and a number line.

Sometimes in the video, you may need to pause to have a go at some of the activities yourself.

Now let's see what we have today.

Let's begin this lesson by looking at odd numbers.

What can you tell me about them? What patterns can you see? I want you to pause the video and have a look and what do you notice about the odd numbers? So pause, have a think and then tell the person next to you.

How did you do? what did you notice about the odd numbers? Looking at the odd numbers.

They all end in one, three, five, seven, or nine.

And it starts at an odd number and then skips a number which is an even number, and then goes to the next odd number.

Let's have a look at this number line.

Let's try and find some pairs of numbers, which have a difference of one.

Let's have a think for a moment.

What does that mean? A difference of one? I think it means that there is only one number between them.

For example, we have the number 4, and here we have the number 5.

There is a difference of one between these two numbers.

Let's see what that looks like as an equation.

So we've got 5 take away 4 is equal to 1.

This is showing us that there is a difference of one.

We could also do 5 take away 1 is equal to 4.

So we've got 1 being the difference.

It's a difference of 1.

Using the same number line, I want you to have a go at finding a pair of numbers, which have a difference of 1.

It's like doing a jump forwards or backwards by 1 from a number.

I want you to pause the video and have a go.

So how many pairs of numbers have a difference of 1? How did you do? Here are some examples of what you could have had to show a difference of 1.

You can have 1 and 2, which has a difference of 1.

So this time you've jumped forward to plus 1, and then we have 20 minus 1 is equal to 19 so 20 and 19 have a difference of 1, but this time the jump is going backwards.

You might've found some others.

Having a look at this block.

Does this block show a difference of 1? How do you know? Looking at the block, does this block show a difference of 1? And how do you know? Can you shout it out? You're right.

It doesn't show a difference of 1.

It's actually showing a difference of 2.

So you've got 0 plus 2 is equal to 2.

So from 0 to 2, there's two jumps.

So it's a difference of 2.

Now let's find some other ways of finding a difference of two.

Can you pick a number between 0 and 12? Let's use 0 and 12.

Shout it out at the screens.

And the first number I hear I'll put a circle around it.

Ready, steady, go! A number from 0 to 12.

Wow, I heard so many numbers, but the first one I heard was 8.

Okay, so now we've got a starting point.

We need to find it's partner to show a difference of 2.

We could go forwards or backwards on the number line, but whichever way we decide to go, it needs to be two steps or two jumps in order to show a difference of two.

Let's try it together.

Let's do a jump of two from 8.

Are you ready? One, two, and we've landed on the number 10.

Now let's put that into an equation 8 plus 2, so the difference of 2 8 plus 2 is equal to 10.

We could also go the other way on the number line.

So instead of going forwards from 8 to 10 doing two jumps, we can go backwards and make a subtraction equation.

Like this, are you ready? Let's look at 8.

Let's do two jumps going backwards.

We've got one, two, and we even landed on the number 6.

Now let's put that into a subtraction equation.

8 minus 2 is equal to 6.

Now I think you're ready for the independent task today.

For today's task, I want you to use a number line and write as many equations as you can with a difference of one or two.

So that's doing one jump or two jumps between the two numbers.

There aren't any answers today.

As I want you to explore as many equations as you can, with a difference of one or two, you may want to use the number lines to help you and to draw the jumps between the numbers.

Remember we are doing difference of one or two.

So you have one jump or two jumps.

Remember you can go forward or backwards.

I want you to pause the video to complete your task and resume once you've finished.

If you'd like to share your work with Oak National, please ask your parent or carer to share your work on Twitter, Instagram, or Facebook tagging @OakNational and #LearnwithOak.

Hope you had super fun with looking at the difference between the numbers.

You did some great exploring.

Now I want you to complete the quiz to see everything that you have learned, and now that's bye from me.

Bye!.
