Lesson video

In progress...

Hello, my name is Miss Robson.

Today we're going to be practising our number bonds to 10.

We're going to figure out how to partition, to find out what a missing part might be.

And then we're going to play a game of memory with our number bonds.

For today's lesson you'll need 10 things that you can use to represent your number bonds.

These could be cubes, counters, pencils, pens, pasta.

You also need number cards from one to 10.

You could write these on pieces of paper if you need.

Pause the video now to collect the resources that you need.

Today we're going to be talking about number bonds to 10.

Hopefully you've heard before about number bonds.

These are just the parts that make up a number.

We can have number bonds to five, to six, to seven, to eight, to nine, to 10, to 20.

But today we're just going to be practising on number bonds to 10.

These number bonds are really helpful because we can use them later on when we're working out equations, or trying to find missing parts.

So when I'm learning about my number bonds to 10, I need 10 things because that will be my whole.

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

I have 10 blue cubes.

I've stuck them all together.

What I'm thinking about my number bonds, I'm thinking about different parts that I can add together to make 10.

So I've got one here and nine here.

One and nine make 10.

I can also have four and six, four and six make 10.

I can swap the parts around and have six and four make 10.

There are lots of different ways to make 10, and it's really helpful to have some concrete materials to help you figure out the different parts.

If you don't already have your things in front of you, you might want to pause the video and grab them.

I'm going to show you some number bonds, and it might be helpful for you to make them in front of you as well.

Here, I'm going to demonstrate to you systematically the different number bonds to 10.

I have zero and 10.

Zero and 10 makes 10.

And you can join in with your resources, but you can also join in by trying to say it the full sentences that go with the different number bonds.

Zero and 10 make 10.

One and nine make 10, one more time.

One and nine make 10.

Two and eight make 10.

Three and seven make 10.

Remember, I'm not taking any away or bringing any new cubes.

There's always just 10.

Four and six make 10.

Oh, the towers are the same height.

That must mean the parts are equal.

Five and five makes 10.

Six and four makes 10.

Seven and three makes 10.

Eight and two makes 10.

Nine and one makes 10.

And our last number bond.

10 and zero makes 10.

Those are all the number bonds to 10 when we're breaking into two different parts.

Now that we've thought about number bonds, and looked at our number bonds to 10.

We're going to think about how we can partition to find the other part if we only know one part.

If one part of my number bond is eight, what's the other part? If you're not sure you could use your fingers, or you could use those things that you collected earlier, cubes, pencils, pasta, whatever it was to sort into groups to figure out.

If you make one part with your eight, you'll find the leftover will be your other part.

If I know one part of my number bond, but not the other part, there are a few things that I could do.

First I could start with my things.

So I have one, two, three, four, five, six, seven, eight, nine, 10 cubes.

If I know that one part is seven, and I want to know what the other part is.

I can partition to find out.

So I can break the stick.

One, two, three, four, five, six, seven.

If I break there, I have one part as seven.

And my other parts, which is one, two, three.

Seven and three make 10.

I could also count on to 10.

I know I have seven and I'm trying to figure out what the other part is to make ten.

Seven, eight, nine, 10.

Seven and three make 10.

Those are two different ways that you could find out the missing parts.

Now that we've really practised on number bonds, and hopefully we know them a little bit better.

What we're going to do is we're going to play a game of memory with our number bonds.

You'll need your number cards for this because we're going to turn them all over.

And we're going to play a game where you turn one, and you have to find its partner.

On the screen you can see eight and two.

Eight and two more make 10.

They are one of our number bonds to 10.

If I turned over eight, I would be trying to find the number two to turn over, and they match as a pair.

It's your job to try and find as many pairs as possible.

You could play with a talk partner, a parent, or carer, or you could play by yourself.

Like I'm going to today.

To play memory you need to have your number cards from one to 10 on your table, faced down so that you can't see what they say.

Because my light is shining on mine, you can see through them just a little bit, but I can't see through them when I'm looking at them on my table.

What I then need to do is I need to turn over one card.

To start with I'm going to turn over this card here.

This card is the number nine.

I've turned over the number nine, and I need to find its partner.

So I have my cubes and you should have your things with you too, to check and help you if you need.

So I know that one, two, three, four, five, six, seven, eight, nine will be one card, which means that I'm looking for my other part, which is just one.

I have to see if I can find a card that's written one on it.

What about this one? Does that say the number one? No, that's not right.

So I need to turn them both over.

I only get to keep the pair if I find both of them the first time that I turned them over.

If you're playing with someone else, now you would let them have a turn.

But because I'm playing by myself, I'm going to have another turn, and see if I can find a pair this time.

I'm going to turn over the number two.

So, one, two, three, four, five, six, seven, eight, nine, ten.

So, one, two is one part, which means I need to find a card that says one, two, three, four, five, six, seven, eight.

I need a card that says eight.

Oh, didn't I turn over a card that said eight before? Was it this one? No, I don't think it was that one.

Was it this one here? It was, that's the number eight.

So because I have found the two parts that go together to make 10.

Eight and two make 10, and two and eight make 10.

I am going to keep them as a pair.

They go together and I'll pop them over to the side over here.

So now I've got the rest of my cards.

And do you keep playing until all of the pairs have been matched up? Now that you've watched me play number bond memory, it's time for you to have a go.

You can play with a talk partner, or you can play by yourself like I did today.

You'll need to get your number cards, and your things that might help you if you get a bit stuck trying to find the other partner for your one of your cards.

Pause the video now to complete your task.

When you're finished, press play.

Did you have fun playing? Did you find all the pairs? I had a bit of a mystery.

I had one card left that had no partner.

I wonder what is the number bond that goes with 10 to make 10? I might need to use my cubes to figure this one out.

When I played I said that I had this card leftover, but it didn't have a partner, the number 10.

Here are my manipulatives one, two, three, four, five, six, seven, eight, nine, 10, and 10 is a part.

What do you think the other part might be? The other part is zero.

If I have 10 as a part, I have zero in my other hand.

10 as a part and zero, just like if I had one as a part and nine as a part.

The other card that I had that didn't have a partner was this card here.

That's the number five.

It's the number five.

So here are my 10 blocks.

One, two, three, four, five.

Oh, they're the same size.

They must be the same size part.

One, two, three, four, five.

Both of them have a number five.

Five plus five is equal to 10.

This card doesn't have a partner because in a pack of number cards, I only have one card that says five.

To find a pair I'd have to have two cards with the number five written on them.

Did you find any cards that didn't have a partner? If you did, why don't you use your blocks to try and figure out what its partner should be.

I had so much fun today playing memory to practise my number bonds.

I hope you did too.

You've done some sensational learning.

Why not share it 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 LearnwithOak.

We'd love to see what you've been doing.

Thanks again for playing with me today.

See you next time.
