Lesson video

Today, we are going to be learning to find one more or one less and 10 more and 10 less.

This is lesson five.

For the topic of numbers to 100 and beyond.

You will need, a paper and a pencil.

There are times when you will have to pause the video to have a go at some of the activities yourself.

Let's get started.

We are going to be looking at a quick starting quiz, some key vocabulary, our star words, counting one more and one less than a given number, counting 10 more and 10 less than a given number.

Writing numbers up to 100.

An independent task is going to answers and a final quiz to see what we have learnt.

Here, we have our star words, star words.

That means we need to do some of the star words in our lesson today.

I am going to use my star word.

And when I say the star word, then I want you to say after, One more.

One less.

One fewer.

Ten more.

Ten less.

Ten fewer.

Good job, let's get started.

Begin today's lesson with great copying some of our counting skills.

How many pencils are there in the picture? I want you to pause the video.

Did you find out how many pencils they are? Shout out your answer.

Was it the same as mine? There are 13 pencils.

Great job, I like that you counted the tens and the ones that we've done before.

What happens if we add one more pencil? I know that you're really, really good at counting and using your counting knowledge, put it in your heads.

And we're going to count one more.

Are you ready? One more than 13, can you shout out your answer? Great work, one more than 13 is 14.

There are now 14 pencils.

Wow, let's have a look at it in a sentence.

Something is one more than 13.

I know you've just done that to help me.

We've just said the number out loud.

14 is one more than 13.

Good job, let's see if we can do the next sentence together.

13 is one fewer than, can you say nice and loud for me? That's right, I know that 13 is one fewer than 14.

Good job, let's see if we can practise our skills a little bit more.

Here, we have some more pencils.

As you can see, there is one fewer pencil in one picture compared to the other picture where there is one more.

I would like you to pause the video and count how many pencils there are? And which one has one more? Good job, did you manage to find out the pencils? The first pack has 16.

Let's check that, it's the correct number.

So one pack of 10.

That means there's 10 pencils.

So one 10 and one, two, three, four, five, six, single pencils, so I know that one, 10 and six ones is equal to 16.

Let's have a look at the next picture.

I know that there's one pack of 10, which means one group of 10.

And let's count the other pencils.

One, two, three, four, five, six, seven, one 10, and seven ones is equal to 17.

Looking at the number 16 and 17.

I know the second picture has one more pencil because I know that 17 is one more than 16.

What's happened now? Look at the pictures.

I can see there are 10 more pencils in each picture.

So if we had 16 before and 17, what do we have now? I want you to think about that we've just got 10 more.

So I want you to think about our tens and ones.

Pause the video to find out how many pencils we have now.

How did you get along? Did you manage to find out what 10 more is? Let's have a look together.

Before in the picture we had 16.

Now we had 10 more.

That means we've added 10 more pencils making the new amount, 26.

I know it is 26 because the ones have not changed.

We have added one 10.

Then we had 17 pencils.

Now we added one more 10.

So that means there are now 27 pencils.

I noticed 27 pencils because the ones haven't changed and we have added one more 10.

Now let's see what it would look like on our place value chart.

I want you to have a look.

What's the same? What's different? They are showing you what the differences between each number.

So for example, here is the number 16.

When we add one more, we change the ones to make 17.

So 16 and one more make 17 and we only changed the ones.

Then we added 10 more to 16.

The tens column has changed from the one 10 to two tens, making it 26.

We also added 10 more to 17 changing the one 10 to two tens, which makes the number 27.

I want you to have a look.

Can you see? Good job, let's see if we can use all this information to help us to do our independent tasks today.

We are going to be looking at the ones and the tens.

Let's see.

So for your test today, I want you to fill in the missing numbers.

I want you to have a look at what is one fewer and one more than a number 10 fewer and 10 more.

Then I want you to complete the sentences using the supports or using the dienes below.

So looking at the numbers, if you want something to help you, you can count, but you don't have dienes you could try making your own and you can use objects around you.

Yesterday I used some of my pens to help me to count.

You might be able to use the same, or you might have something else to help you.

Have it go.

Well done for completing it so quickly.

Let's have a look at the answers.

Make sure you check if you have done one fewer or one more, 10 fewer or 10 more.

Well done, give yourselves a whoosh, whoosh I hope you had lots and lots of fun.

Now, you have to complete your end of lesson quiz to see how well you have done today, bye.
