# Lesson video

In progress...

Hello, my name is Miss Robson.

In this lesson, we are going to be exploring the number bonds that make up five and six.

We're going to start by exploring five, making different parts to find the number bonds.

Then we're going to explore working systematically to make sure that we found all of the answers before exploring six and then it will be your turn.

For this lesson, you will need six things to help you with partitioning on number bonds.

You might like to have some cubes or some beads on a string.

Pause the video now to collect six things and when you've got them press play.

First we're going to start by exploring five I can see five blue cubes in a tens frame on the screen.

One, two, three, four, five now they are all up to the top of the tens frame just in one row like this aren't they.

So, we're going to look at putting that information into a Part-whole model.

I have five in the top row, and zero in the bottom row.

Five is a part, zero is a part the whole is five.

Let's have a look at that written down.

Five is the whole.

I have five at the top and zero at the bottom.

Five and zero, make five.

Can you repeat that sentence my turn, five and zero make five.

Excellent.

We can also arrange five like this.

At the top, I can see that there are three cubes.

At the bottom of the tens frame there are two cubes.

Three is a part, two is a part, the whole is five.

Let's have a look at that in Part-whole model.

There we go, So I five is the whole three is a Part, two is a part, three and two make five.

Excellent, we're going to look at one more.

How many cubes Can you see in the top row of the tens frame? There are four cubes at the top, four How many cubes there are in the bottom row? One, there's one cube at the bottom.

Four is apart, one is apart, the whole is still five.

So, let's look at that in our Part-whole model.

Five is the whole four is apart, One is a part, four and one make five.

When we break numbers up into parts like this, we call them number bonds.

And the more number bonds we can speedily recall, the more they'll be able to help us later on.

We are going to be exploring in the next few lessons, number bonds to five, six, seven, eight, nine and 10.

And the more that we learn these parts of numbers, the easier we will find different things later on, like subtraction and addition.

When we work with number bonds, it helps to work systematically to make sure that we've explored all of the different parts that we can make.

So here are my five cubes, five is part, zero is apart, then I move one to the other side, four is a part, one is a part, three is a part, two is apart, and I continue to move one to the other half as I explore my different number bonds to five.

Let me show you a little bit closer under the visualizer exploring number bonds to five and you can join in with my full sentences.

So here's my Part-whole model that I drew that you could draw your own or you could print one off if you would like It has two parts and it has one whole.

Now I could add more parts, I could draw more parts if I wanted to investigate more than just two parts, but I'm going to start with two cause that is all I need for right now.

I'm going to start by trying to find the different parts of five.

So I put five cubes in my whole.

I'm going to try and work systematically again today.

That means that I am going to put all of these up at the top first, and one by one I'm going to move them to the other part.

If you don't have a Part-whole model, or if you don't want to draw one, what you can do is just have your table and you can have them at the top and then move them down to the bottom as you move them to your second part and just keep them separate from each other in two groups like that.

That is another way that you can work if you would like.

So, here's my Part-whole model, Five in the whole.

I'm going to start by putting all five in the top part So I've got five and zero, five and zero make five.

Can you repeat that sentence? Fantastic, right.

So I'm going to move one down here, four and one make five, your turn.

Fantastic, move another one, I've got three and two make five, your turn.

Excellent, right, I'm going to move one more down here.

Now it's your turn to count as well, how many are here? And how many are here? So, two and three make five repeat the sentence.

Excellent, and I'm going to put one more down here.

one and four make five, your turn.

And I bet you know what this last one is going to be.

I'm going to put this one up here.

So now I have how many here? Zero and how many in this box? Five, so zero and five make five.

Now that we've explored the number bonds to five together, it's your turn to investigate the number bonds to six, what you will need is six things.

So here I have six cubes, but you could use beads and you could count out six, one, two, three, four, five, six.

And you could break them into different parts, so three and three make six and have a go at systematically.

So remember one by one, So six and zero, one and five, two and four, breaking up the different parts of six.

You could record these as addition equations if you would like to.

So now it's time for you to pause the video and go and investigate the number bonds to six.

If you work systematically you can make sure that you have found all the different number bonds.

We're only breaking this up into two parts.

So if you have a Part-whole model to help you that will be fantastic.

If you don't, you can just make sure that you're making two piles with your objects and try recording them if you'd like to, you can record them as addition equations if you would like.

So, I have five and one, five plus one is equal to six.

So now that you've investigated the different parts of six, I thought I would show you some of the different ways that I represented six using my cubes.

Have a look and see if you can see some of the different parts that I've made with these cubes on the screen.

The top representation has six in a row one, two, three,four.

five, six just like this, six is a part zero is a part the whole is six, six and zero make six or zero and six make six.

The next representation down here is a little bit different.

What different parts can you see in this different representation? I've made this representation here, let me turn around so it's the right way for you one, two, three, four, five, six I still have six altogether, but I've made this funny it's almost like an L upside down, isn't it? This one here can show me a few different things.

Either, this one tower here of four and two stuck on, four and two make six or I could see a row across the top of three, and a little bit stuck on down here three, three and three makes six.

This is a different way to represent one of the number bonds to six.

So now that we've looked at the first two together, have a go at describing what you can see in the bottom representation.

So I've made that representation with my cubes, I have a tower of three, a tower of one, a tower of two.

All together there are still six cubes, but this time there are three parts three is a part, one is a part, two is a part, altogether the whole is six, or I could see it as a little L like this, that's three is a part and three is apart, the whole is six.

There are different ways that we can make the number six.

If you've got some cubes that were joined together like this, you could have a go now at trying to arrange your cubes to make some different ways of seeing the number six, or if you would like you can just rearrange whatever it is that you have whether they're counters or beads on the floor to see if you can find some different ways to make six.

I think I put this one over here.

That's a new way to make six.

I still have six cubes, but I've arranged them in a different way.

If you like, you can go and explore the number six, or the number five that we looked at earlier, and see if you can make some different representations.

Thank you for joining me today to explore the number bonds to make six and five.

I've had a really fun time.

I've loved using my cubes in some new and interesting ways and I hope that you have too, if you like, why not share your work with us.
