Lesson video

Hello everyone! Ms. Charlton and Hedwig here, ready for some more exciting learning today.

Now we've got a really wonderfully challenging lesson ahead of us.

Are you ready? We are going to use the make 10 strategy to add one digit numbers.

Now this is part two of the lessons.

Don't worry if you missed part one, you'll still be able to pick it up now and have a great time exploring with us.

So we're going to recap.

We're going to remind ourselves of the make 10 strategy, and then we're going to practise using the make 10 strategy to solve some addition equations.

Then you'll do your independent task and an end of lesson quiz.

Today you're going to need a pencil and some paper.

It might help for you to have some counting items as well, but you don't have to have them if you haven't got them.

So don't worry.

Let's get ready with our star words.

Hands up, star words.

Make.

10! Partition! Can anyone remember what we did to show make 10? Make.

10! Well done.

Right, we are going to explore with an addition equation for a start, eight plus six.

Now, we've talked about this before, and we said that we could just do eight plus six on our fingers, or we could use a number line.

But, what if the numbers get bigger? We will run out of fingers won't we? What if the equation was 18 plus six? It would make it very, very difficult for us.

So we're going to learn a strategy.

We're going to carry on practising the strategy of make 10.

And to do that, we need to partition.

So eight plus six; the first thing that we need to do is make.

10.

Let's see how we do that.

Let's move those cubes into the tens frame.

Look, we've made 10.

There's a group of 10.

But I still have some cubes left over on the side, so I have partitioned that number six.

There were six cubes.

I've moved, I've parted two of those cubes into the tens frame, and there are four left.

Just like this.

There were six.

I moved two of them.

I partitioned two of them into the tens frame to make 10, and there are four cubes remaining.

Ten plus four is equal to 14.

So eight plus six is equal to 14.

Simple as that.

Let's have a little look at the demonstration.

I used some objects to help me count.

So watch this carefully.

Eight plus six is equal to.

Hm.

Let's start off by making 10.

Eight plus two is equal to 10.

So I'm going to take that six and I'm going to partition it to help me make 10.

So I've got the number six because I'm adding six and I'm going to take two because that will help me make the 10.

Let's show you with raisins here.

One, two, three, four, five, six, there's six raisins.

Now I'm going to take two of them to put into that box to partition.

And there are four to put in the other box.

I've partitioned that six into two and four.

Six; two; four.

Eight plus two is equal to 10.

So I took that two to help me make the 10, I've got that.

And now there's four remaining.

So I'll do the 10 that I've just made.

Plus four is equal to.

14.

So.

eight plus six is equal to 14.

So I use the make 10 strategy to help me solve that simply.

Can we try again with nine plus six? Let's have a look.

Nine plus six.

What do I need to do first? Make.

10! Let's go for it.

I'm going to use that six.

I'm going to steal it to help me make 10 for the nine.

Are you ready? Let's move one from those cubes.

There's six cubes and put it into the tens frame.

So we've made 10.

I partitioned the six into parts.

I needed one to make the 10 and there are five cubes remaining to add.

So 10 plus five is equal to 15, nine plus six is equal to 15, 10 plus five is equal to 15.

We solve the equation by making 10.

Now, it's your turn to have a go.

Let's have a look at one together first, because it's a bit tricky.

So we've got the equation here, seven plus five.

I filled it all in for you so that you can see exactly what you need to do.

Seven plus five.

Hm.

What do I need to do first? Make 10! I know my number bonds to 10.

So I know that to make 10, I need to do seven plus three.

Seven plus three is equal to 10.

Can you see I've written that equation there? So in order to make 10, I'll take the five, the five that I'm adding on and I will partition it.

Put the five in the whole part model.

I know I need, I know I need one of the parts to be three.

So I put three in one of the parts.

And then the remaining part to make five is two.

Three plus two is equal to five.

So seven plus three is equal to 10.

10 plus the remaining two is equal to 12, 10 plus two is equal to 12, seven plus five is equal to 12.

I've managed to make a much simpler equation by making 10 first.

Now it's your go to have a go at the other boxes.

Pause the video now, have a go and then come back and we'll check them all together.

How did everybody get on? Should we go through six plus five? Well, we know our number bonds.

So we know that six plus four is equal to 10.

I was adding five.

So I'm going to partition the five.

Put it in the whole part model.

I know that one of the parts has to be four because I have to have four to make a number bond to 10.

So the remaining part will be one.

The number bond that I partitioned, five partitioned into four and one, six plus four is equal to 10, 10 plus the remaining one is equal to 11.

So six plus five is equal to 11.

Let's have a look at seven plus six.

I know my number bonds to 10.

So make 10.

Seven plus three is equal to 10.

So I know I need to partition the six into three and three.

I have to have three to help me make the number bond.

And the remaining amount is three, because three plus three is equal to six.

10 plus three is equal to 13.

So seven plus six is equal to 13.

Are we getting the hang of it now? It's still a bit tricky isn't it? Let's go through the last one together.

Six plus six.

Right, I need to make ten first.

Six plus four is equal to 10.

So let's partition the six.

Make sure that we've got a four.

And the remaining part is two.

Six plus four is equal to 10.

Take that 10.

Add the remaining two, 10 plus two is equal to 12.

So six plus six is equal to 12.

Really fantastic work.

I think we deserve something special.

Shall we have a rollercoaster clap today? Are you ready? Get your roller coaster ready.

Chicka, chicka, chicka, chicka.

Woo, woo, woo! We definitely deserve that.

Should we wake up that sleepy Hedwig, and tell her all about our learning? Right then, Hedwig, today was a super challenging lesson.

We got to watch a little video as well of how to use different resources to count.

So I used raisins, but you could use nuts, you could use even teabags to help you count.

Be careful not to eat those raisins, otherwise you might get, not get the right amount.

So, Hedwig, we used raisins to help us count out because we were petitioning the ones to help us make 10.

Now, the reason we were making 10 was because it makes it much easier to add up much quicker and simpler to add up.

Once we've learned how to do the strategy really well, we'll be able to be super speedy with it.

Do you think you'd be able to do that, Hedwig? She sounds pretty happy today, doesn't she? Even though it was a challenging lesson.

Now you can go and complete your quiz and I'll see you again very soon.

Bye-bye everybody!.
