Lesson video

Hello mathematicians, it's Miss Charlton here, and my talk partner Hedwig, and we are back for some more exciting learning.

Let's find out what we're going to do today.

We are going to use the Make 10 strategy.

Now, when we do, Make 10, we have to go, make 10! And making 10 will help us solve equations.

We're going to recap on number bonds to 10.

Those are very important.

And then we're going to understand and use the Make 10 strategy.

And then you'll do your independent task and your end of lesson quiz.

In today's lesson, you'll need a pencil, some paper, and a pole, pole! I just swapped those letters over there.

A whole part model, not a pole heart model.

A part whole model.

Let's get ourselves warmed up.

I think I need my brain warming up because clearly I'm getting my letters swapped over the wrong way.

So we're going to get ourselves warmed up by having a look at these equations and figuring out which ones are less than 10, which ones are more than 10, and which ones are equal to 10.

Pause the screen now.

Have a look at those equations and then we'll come back and check them together.

Are you ready to explore? Let's have a look.

So first of all, let's look at five plus six.

I know that five plus five, double five, is equal to 10, and six is more than that.

So it must be more than 10.

Five plus six is equal to 11.

What about this one, a four plus five? Well, I know that double four is equal to eight, so I know that four plus five must be equal to nine, which is less than 10.

And this equation, three plus nine? Well, I can use count on because there's not many ones there, nine, 10, 11, 12.

That's more than 10.

It's good to use different strategies to try and solve these.

Well, nine plus four? Well, I know 10 plus four is equal to 14, so nine plus four must be equal to 13, which is more than 10.

Another strategy there.

And then, two plus six? Well, that's easy just to count on.

Six, seven, eight.

That's less than 10.

And this one here, we know our number bonds to 10.

Eight plus two is equal to 10.

That's a number bond to 10.

Are you all nice and warmed up now? Hopefully you are.

Look at all those presents, and those cheeky elves.

Do you think they're being helpful in wrapping them or do you think they're being a bit sneaky and just playing with them? Have a look and choose which present you would like.

Oo, I think maybe I like the Jack In A Box today, that looks a bit fun.

We are going to use those ideas to help us solve some equations today.

So our first equation is here.

We've got a number bond filled with presents.

What strategy could we use to add eight and six? Hmm, eight plus six.

Well, it's a little bit tricky to do count on because there would be so many jumps on the number line.

And if we have to do lots of jumps, it means there's more chance that we could make mistakes.

So what we could do is use the strategy, Make 10! Can everybody do that? Make 10! Once we've made 10, it makes it much easier to be able to count on.

So let's use the Make 10 strategy.

I've got a 10's frame here to help me.

And I've got one of my parts, one of the presents.

You remember the parts here? We've got one of the parts over here.

We've got the eight red presents.

So there's eight, that's one of the parts, and we need to add six.

Can you see the six blue presents over there? So what we do first is make 10.

Let's move those presents over to make 10.

Now, can we add it more easily? Are you ready? 10 add four more is 14.

10, 11, 12, 13, 14.

Now isn't that easier than adding eight and six? Eight and six.

You'd have to try and go eight, nine, 10, 11, 12, 13, all the way up.

But this way we can just do a group of 10, make 10, and add the ones.

10, 11, 12, 13, 14.

10 plus four is equal to 14, eight plus six is equal to 14.

There it is represented as a number bond.

The whole is fourteen, the parts are eight and six.

Let's have a little think and develop that a bit more.

This little girl says, I have 13 red and blue presents in total.

Five are blue.

How many are red? I have 13 altogether in total.

Five are blue.

How many are red? So we know the whole, and we need to figure out the parts.

Let's see if we can use the strategy to solve that equation.

Here it is.

Here's my part, here are my one, two, three, four, five blue presents.

So she said that five are blue.

And there are five blue presents.

And she said that we have 13 altogether.

But we need to figure out what the missing part might be.

The whole is 13.

The parts are one, two, three, four, five.

And, can you pause the video now and see if you can figure out what the missing part might be.

Remember to use Make 10! To see if you can help.

Pause the video now, and then come back and we'll check together.

Let's have a look at that.

I found the missing part was eight.

Because I know that the total is 13, I know that one of the parts was five.

I know that five plus five is equal to 10.

So I needed to do five plus five, is equal to 10, and then three more.

10 plus three is equal to 13, five plus three is equal to eight.

So the missing part was eight.

Let's have a look at that on here, shall we? So we've got our five presents.

We've got our eight presents here, and our five blue presents.

One, two, three, four, five.

Let's see what we can do to solve it.

What we need to do first is to Make 10! Let's move those presents to make 10.

One, two, three, four, five.

So there we go, we've made 10.

And how many are on the outside? How many one's are left? There are three.

10, 11, 12, 13.

10 and three more is 13.

Five plus eight is equal to 13, eight plus five is equal to 13.

Can you see how making a group of 10 makes it much easier to add up those numbers? Now it is your turn to see if you can explore these numbers by the using the Make 10 strategy.

You've got some 10's frames, and you need to add them up and see how many ones are left using Make 10! Every time we make 10, I want you to do the actions of that.

See how many times you do it.

Use that 10 frame to help you.

Pause the video now, and then come back and we'll check the answers together.

How did everybody get on? Let's go through them.

So we had eight plus five, which is the one we've done, which is equal to 13.

A group of 10 and three more presents.

Six plus eight.

I make 10, and there are four more, six plus eight is equal to 14.

Five plus six.

Make 10, and one more is 11.

Four plus seven.

Make 10, and one more is 11.

You have done a fabulous job at making 10 today.

Well done everybody.

Let's have an Incredible Hulk clap to celebrate.

Ready, get your hands ready.

Hulk! Really good job.

Shall we wake up that sleepy owl now? Come on Hedwig, wakey, wakey.

Oh, she's shaking her head.

She doesn't want to wake up.

Are you a bit tired today? I think she's a bit sleepy.

She missed out lots of her learning.

Right, well Hedwig, don't worry, we'll tell you.

What did we do first, children? Let's have a think.

Oh, well, we recapped.

We went over our number bonds to 10 because we knew that that was going to help us in today's lesson.

So we recapped our number bonds.

And then we used the Make 10 strategy.

Did you see our actions for Make 10? Everybody, can you show a Hedwig the actions for Make 10, please? She's watching.

Make 10! Well done.

I think Hedwig wants to try that but she's going to find it tricky because she's got wings.

So we use the Make 10 strategy to solve some addition equations.

Do you think you understand that Hedwig? Oo, she's struggling today.

Do you want to tell me what's wrong? Hedwig, first of all I just want to say you're so brave for telling me what you found difficult, because sometimes it's hard to admit when things are difficult, isn't it? So what Hedwig said to me, do you mind me sharing with them? Okay, she doesn't mind me sharing.

What Hedwig said was that she still struggles with her number bonds to 10.

Which means that she finds other addition equations difficult.

And I think that that's true.

If you still find your number bonds to 10, tricky, then it makes it difficult to do more complicated ones.

So what I'm going to do with Hedwig later after this lesson is I'm going to show her some number bonds to 10.

Like this.

Let me make the screen big so you can see.

So I'm going to go through all of the number bonds to 10 with her.

The whole is 10, the parts are zero and, oh, what would the other part be? Well, zero plus, can you shout it out? Well done.

Zero plus 10 is equal to 10, and then one plus nine, and then two, and then three.

And I'm going to complete all the number bonds with Hedwig, and then we're going to practise them.

We might even make a little song to go with them so that she knows her number bonds to 10.

Because I think she's feeling a bit nervous that she can't do the other maths.

So if you feel that way as well, maybe you'd like to have a little practise.

Just like wonderful Hedwig is.

So, do you think that that will be nice, Hedwig? Would you like to practise your bonds to 10 with me? I think she's feeling much more confident now, knowing that we're going to have a little practise of those bonds to 10.

Now everybody, it is your turn to go and do your quiz, and I will see you again very soon.

Bye bye.
