Lesson video

Welcome to your maths lesson with me, Mrs. Harris.

Together, we'll be exploring one fewer within six.

This is our lesson agenda.

It means what we're going to do in the lesson.

So, we're going to start it off with a song, then we'll have our new learning, a talk task where you get to talk about your new learning, and then we'll develop our understanding of one fewer, and then we'll finish off with some independent learning so you can show me everything you've learned in the lesson.

Let's find out what you need.

It would be great if you could have some counters.

If you haven't got any counters at home, it doesn't matter what colour they are, I've put green on the screen, but mine are red or yellow.

You could use buttons if you don't have counters.

Even the chocolate ones.

You could also use coins or really anything you've got around.

I'd like you to have the printed worksheets, and under the supervision of your parent or carer, I'd like you to have a pair of scissors, please.

So, if you don't have any of them things with you right now, pause the video, go and find them, and then come back to me.

I'll be waiting.

The song I've chosen is There's Six in the Bed.

So, let me just check we've got six in the bed.

One, two, three, four, five, six we have, so let's lay them down.

♪ There's six in the bed ♪ ♪ And the little one said roll over, roll over ♪ ♪ So they all rolled over and one fell out ♪ ♪ There were five in the bed ♪ ♪ And the little one said roll over, roll over ♪ ♪ So they all rolled over and one fell out ♪ ♪ There was four in the bed ♪ ♪ And the little one said roll over, roll over ♪ ♪ So they all rolled over and one fell out ♪ ♪ There were three in the bed ♪ ♪ And the little one said roll over, roll over ♪ ♪ So they rolled over and one fell out ♪ ♪ There was two in the bed ♪ ♪ And the little one said roll over, roll over ♪ ♪ So they all rolled over and one fell out ♪ ♪ There was one in the bed ♪ ♪ And the little one said ah, good night ♪ I like that song.

Thanks for singing it with me.

In that song there were fewer and fewer people in the bed, weren't there? There's quite a few songs like that.

The one about the speckled frogs on the speckled log is like that, too, where we get fewer and fewer frogs every time.

Let's sing that one together, and let's start with counting how many frogs are going to be on the log because a little bit of counting's always good in a math lesson.

So, we've got one, two, three, four, five, and six frogs.

So, our song is going to be just like there were six in the bed.

We're going to have six speckled frogs.

♪ Six little speckled frogs sat on a speckled log ♪ ♪ Eating some most delicious grubs, yum, yum ♪ ♪ One jumped into the pool where it was nice and cool ♪ ♪ Then there was five little speckled frogs, glug, glug ♪ ♪ Five little speckled frogs sat on a speckled log ♪ ♪ Eating some most delicious grubs, yum, yum ♪ ♪ One jumped into the pool where it was nice and cool ♪ ♪ Then there were four little speckled frogs, glug, glug ♪ ♪ Four little speckled frogs sat on a speckled log ♪ ♪ Eating some most delicious grubs, yum, yum ♪ ♪ One jumped into the pool where it was nice and cool ♪ ♪ Then there were three little speckled frogs, glug, glug ♪ ♪ Three little speckled frogs sat on a speckled log ♪ ♪ Eating some most delicious grubs, yum, yum ♪ ♪ One jumped into the pool where it was nice and cool ♪ ♪ Then there were two little speckled frogs, glug, glug ♪ ♪ Two little speckled frogs sat on a speckled log ♪ ♪ Eating some most delicious grubs, yum, yum ♪ ♪ One jumped into the pool where it was nice and cool ♪ ♪ Then there was one little speckled frog, glug, glug ♪ ♪ One little speckled frog sat on a speckled log ♪ ♪ Eating some most delicious grubs, yum, yum ♪ ♪ One jumped into the pool where it was nice and cool ♪ ♪ Then there were no little speckled frogs, glug, glug ♪ Did you notice in this song we got fewer and fewer frogs every time? Just going to ask the frogs to come back, though.

Come back, frogs! Frogs! One, two, three, four, five, six.

They're all back.

We were counting forwards, weren't we? When we have fewer, it means there's going to be less frogs, fewer frogs.

And every time one jumps into the pool, we have one fewer.

So, at the moment, we have six frogs.

One's going to jump into the pool, so we'll have one fewer than six on the log.

Let's see what I mean.

So, frog number six, could you jump into the pool where it is nice and cool? And we'll have one fewer on the log.

There he is.

He's gone, and now we have one fewer on the log.

We have one, two, three, four, five frogs on the log.

Five is one fewer than six.

Another one is going to jump into the pool, so we'll have another one fewer.

We'll have one fewer than five.

And one fewer than five is four.

Hmm, if our fourth frog, frog number four jumps into the pool, we'll have one fewer on the log.

How many will we have when he's jumped into the pool? That's right, we'll have three flow.

Oh, tongue twister.

We will have three frogs left on the log.

Ooh, did it.

So, we have three frogs in total.

We'd like one fewer on our log.

So, one is going to jump into the pool, and we will have one fewer than three.

Two is one fewer than three, and one is one fewer than two.

What's one fewer than one? It's none! No frogs on our log.

Well done.

You're getting great at finding one fewer.

So, now you know how to find one fewer.

I'd like you to use your counters and I'd like you just to get a few in your hand.

I've got this many.

I'm going to count them.

One, two, three, four.

There are four counters all together.

Ooh, slippery ones, too.

There are four counters all together.

I can say that one fewer than four is.

Now, I want to do it without taking one away.

One fewer than four is three.

One fewer than four is three.

I did have to take it away, and it helped me, but I've popped it back so I can do my sentence.

There are four all together.

One fewer than four is three.

So, that's what I need you to do with lots of different numbers all the way up to six.

Find out what one fewer is using your counters, and explain using my sentences.

There are hmm all together.

One fewer than hmm is hmm.

So, pause the video and have a go at your talk test now.

Come back to me when you're done, though.

How did you get on with the talk test? Were you able to find out what was one fewer than the amount of counters you picked up? Wow, you're getting really good at this.

And just to develop your learning that bit further, my friend Vel has come to help.

Hi! Here he is.

And we're going to play a little game together.

We like playing games together, don't we, Vel? Mm-hmm.

And our game is going to use the number track you can see on the screen underneath.

We've got the number one, two, three, four, five, and six.

And we're going to use them to play a little game.

Let me show you.

Vel, would you choose a number, please? Two! Like the number of wings I have.

Well, yes, you do have two wings.

But now, we need to put two counters on my board because Vel chose the number two.

Now, I can use a number.

Thanks, Vel.

But my number has to be next to the two.

It can be the number one or it can be the number three, and I'm going to choose the number three.

Now, I have to put three counters on the board.

One, two, three.

And the winner is the person with the one fewer counter.

Vel's having a look.

Who's got one fewer? It's Vel with his two counters.

Two is one fewer than three.

Oh, well done, Vel.

Good go, good go.

Okay, let's pop these back.

Should we have another go? Yes, let's have another go.

So, hmm.

Is it my go first? I hope it is 'cause I've chosen number four.

I'm going to put four counters on.

One, two, are you checking, Vel? Three, four.

What number are you going to choose, Vel? Hmm.

Ooh.

Three! You chose number three? Hmm, why did you choose number three? Because it's one less than four.

One fewer than four.

Oh, I like how you corrected yourself then.

You said the word fewer instead of less.

Okay, so let me see because if you're right, Vel, you've won this round, as well.

One, two, ooh, and three.

Oh, my counters make it quite clear, don't they? That three is one fewer than four, so Vel is the winner.

Well done, Vel.

Okay, one more round? Let's see.

I'm going to choose the number six.

I had four on the board, so I'm just going to save a bit of time and I'm going to put two more on.

Just check with me.

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

I have six pegs.

Mrs. Harris, on our number track, all the numbers are less, are fewer, sorry, fewer than six.

So, I'm going to choose one fewer than six, five.

You're choosing five, are you, Vel? Okay.

One, two, three, four, five.

Oh, Vel, you won again! Five is one fewer than six! It's easy.

The numbers that are fewer are that way on the number line.

And the numbers that are more are that way on the number line.

Oh yes, Vel.

I can see it now.

You're telling me that.

Oh, they start at the six, Vel.

Six.

Five is one fewer than six.

Four is one fewer than five.

Three is one fewer than four.

Two is one fewer than three.

And one is one fewer than two.

Oh, thanks for helping me develop my learning, Vel.

You're awesome.

Now it's time for you to do your independent learning, and I think you are going to be amazing at it.

You're going to need the worksheets that I said you should get at the beginning of the lesson.

And if you're allowed and you're supervised, that pair of scissors.

I'd like you to look at each of the groups of fruits and vegetables, or the frogs, or the grubs, or the ducks, and the eggs.

I'd like you to count how many you have.

So, if I looked at the oranges I can see right now I would say I had one, two, three, four.

I had four oranges.

Then I'm going to get my scissors and snip one off the end.

Now I have three oranges.

One fewer than four is three.

When you do pause for your independent learning, keep this screen on because it will help you with your sentence starters, and they're really important.

So, pause the video now and enjoy finding one fewer.

Okay, are you back? Let's find out the answers.

Okay, so I did use my oranges, didn't I? And I did chop one off.

One fewer than four is three.

And look, then I had my bananas, and I chopped one off of them, as well! I had three, and one fewer than three is two.

What should I use next? I think I'll chop off one of the ducks.

Hmm, I chose to chop it off the other end.

Does that make a difference? No, it's still making one fewer, wherever I took the one from, isn't it? So, I had five ducks.

I had five ducks.

Now I have one fewer, and I have four ducks.

Four is one fewer than five.

Then I did my eggs, and well, I took it off that end, as well, 'cause I realised it doesn't matter which end I chop it off.

I'm still making fewer.

So, I have four eggs.

Now I have three eggs.

One fewer than, well, one fewer than four is three.

And then I finished everything else off.

I just thought you might like to see how I got on.

I hope you got on just as well as I did.

Sometimes when I'm eating my tea I like to think of one fewer.

Maybe if you've got some fish fingers or sausages and you've eaten one, you've got one fewer, haven't you? Just don't know how many you started with.

We've reached the end of our lesson on finding one fewer within six.

Maybe you'll go on to do it when you're having tea, or eating some biscuits, maybe.

We can always think about one fewer.

If you'd like to share any of your work with me, or with everybody at Oak National, you could ask a parent or carer to share your work on social media, and all the details are on the screen.

Bye!.
