Lesson video

Hello there, my name is Mr. Tilstone.

I'm a teacher and welcome to my favourite time of the day, maths time.

Today's lesson is going to be all about time.

Time can be quite a tricky concept, but don't worry, I'm here to guide you through it every step of the way.

And with a positive attitude, anything's possible.

So if you are ready, let's begin.

The outcome of today's lesson or the target for the lesson is this, I can use both hands on a clock face to show what hour it is and when it is half past the hour.

You might have had some recent experience of doing that with just the hour hand.

Today we're going to use the hour hand and the minute hand.

Our keywords, which we're going to do in a my turn, your turn style are, my turn, hour hand.

Your turn? My turn, minute hand.

Your turn? My turn, o'clock.

Your turn? If you don't know what those words mean at the moment, don't worry, we're going to practise them lots in this lesson.

By the end you'll be an expert.

Our lesson today is split into two parts or two cycles.

The first one is going to be telling the time to the hour, that's using both hands.

And the second telling the time to the half hour, again using both hands.

But if you are ready, let's start by telling the time to the hour.

Let's go.

In today's lesson, you are going to meet Izzy, Jun, and Lucas, and maybe you've met them before.

They're here today to give us a helping hand.

Have a look at these two clocks and tell me what's the same about those clocks and what's different? You might want to take a few moments to have a look, see what you can notice about them.

Well, they've definitely got something in common, something that's the same about them.

And I'll give you a clue, look at the hour hand, have you spotted it? The hour hand on both clocks is pointing to one.

So they're both showing one o'clock.

It's just that perhaps the minute hand dropped off the first one.

And that's what's different about them.

The clock on the right's also got a minute hand, that longer hand.

When the minute hand is pointing to 12, it is o'clock.

So that's a special place for the minute hand to be.

And when it's pointing at 12, it's o'clock.

The minute hand is longer than the hour hand.

Can you see that? So the hour hand is shorter, the minute hand is longer.

It's sometimes called the long hand.

We're not going to call it that today, we're going to call it the minute hand.

The hour hand is shorter than the minute hand.

It's sometimes called the short hand.

But again, we are not going to call it that today, we're going to call it the hour hand.

Let's have a quick check.

Let's see if you can remember those facts.

Have a look at that clock.

A is pointing to one of the hands and B is pointing to a different hand, but which is which? So A is the hmm hand and B is the hmm hand? Pause a video and I'll give you the answer in a second.

Well, let's have a look.

A is the minute hand.

So the minute hand is longer.

And B is the hour hand.

The hour hand is shorter.

In one hour the minute hand moves around the clock once, one time, from 12 to 12.

The hour hand moves more slowly to the same time between one hour and the next.

So they're both moving all the time, just at different speeds.

We've got a stem sentence here.

I'll say it, then we'll say it, then you say it.

So the sentence is this, the hour hand is pointing directly to hmm, so it is hmm o'clock.

Can you say that with me? Let's go, the hour hand is pointing directly to hmm, so it is hmm o'clock.

Now just you say it, off you go.

What do you think we can say about this clock? Where's the our hand pointing? Let's have a look.

To one.

So the stem sentence is the hour hand is pointing directly to one, so it is one o'clock.

Can you say that with me? The hour hand is pointing directly to one, so it is one o'clock.

Now we're going to make a little change to that stem sentence.

The hour hand is pointing directly to hmm, and the minute hand is pointing directly to 12, so it is hmm clock.

Hmm, let's have a look.

So the hour hand is pointing directly to one, just like before.

And the minute hand is pointing directly to 12, so it's one o'clock.

So we are showing one o'clock again, but this time with the minute hand.

Let's try that again.

The hour hand is pointing directly to hmm, and the minute hand is pointing directly to 12, so it is hmm o'clock.

What do you think? How can we fill it in this time? The hour hand is pointing directly to two and the minute hand is pointing directly to 12, so it is two o'clock.

Will you say that with me? Are you ready? The hour hand is pointing directly to two and the minute hand is pointing directly to 12, so it is two o'clock.

Let's do another one.

The hour hand is pointing directly to hmm, and the minute hand is pointing directly to 12, so it is hmm o'clock.

What do you think? How can we fill it in this time? Like this, the hour hand is pointing directly to three, and the minute hand is pointing directly to 12, so it is three o'clock.

Will you say that with me? Ready? The hour hand is pointing directly to three and the minute hand is pointing directly to 12, so it is three o'clock.

So just like before when you learned that the hour hand points straight to a number for o'clock, it's still the same thing, but this time the minute hand is pointing to the 12.

Let's have a look at this one.

Is this clock showing four o'clock? Hmm, and why? What do you think? It could be because the hour hand is pointing directly to the four, but it's actually not.

No, the minute hand is pointing to 1, not 12.

So when it's o'clock, the minute hand points to 12, to the top of the clock.

Is the clock showing four o'clock this time, and why? Have a look.

Hmm.

Again, it could be, it partly is, because the hour hand is pointing directly to four.

But look at the minute hand, is it pointing directly to 12? No, it's not.

It's not in the right place.

The minute hand should be pointing directly to 12.

Not near it, on it directly.

Is the clock showing four o'clock? Why? Hmm, have a look at this one.

Well, I can see a hand pointing directly to 12, and I can see a hand pointing directly to four, but are they the right hands? They're not.

The hour hand should be pointing to four, not the minute hand.

And the minute hand should be pointing to 12, not the hour hand.

So they need swapping over.

Is the clock showing four o'clock this time? Why? Have a look.

It looks right this time, doesn't it? Yes, it is showing four o'clock.

And we can use our stem sentence again.

The hour hand is pointing directly to four and the minute hand is pointing directly to 12, so it is four o'clock.

Will you say that with me? The hour hand is pointing directly to four and the minute hand is pointing directly to 12, so it is four o'clock.

Let's have a little check shall we? Use the stem sentence to give the time.

So that stem sentence again.

The hour hand is pointing directly to hmm, and the minute hand is pointing directly to 12, so it is hmm o'clock.

So I want that whole sentence, please.

Pause the video, practise it, maybe do it two or three times, and I'll see you soon for some feedback.

Did you manage to get it? Let's have a look.

The hour hand is pointing directly to five and the minute hand is pointing directly to 12, so it's five o'clock.

Very well done if you've got that, you are on track, you're doing really well.

Izzy is looking at this clock and she says, "I think the hour hand has fallen off the clock." Hmm, is she right? I certainly can't see the hour hand, can you? I can see the minute hand, can't see the hour hand.

The hour hand though is actually right behind the minute hand, and I'll show you that, 'cause let's take away that minute hand, look, and there it is, there you can see it.

And we'll put the minute hand back on in a sec, but there is that shorter hour hand.

So let's use our stem sentence this time.

The hour hand is pointing directly to hmm and the minute hand is pointing directly to 12, so it is hmm o'clock.

So think about the hour hand, how can we fill it in this time? The hour hand is pointing directly to 12 and the minute hand is pointing directly to 12 as well, so it is 12 o'clock.

So it looks like it's fallen of, but it's not, it's just behind the minute hand.

They were both at exactly the same position.

So every day, twice a day, in fact, that happens to the clock.

Let's have another check.

It is seven o'clock, but the hands have fallen off the clock.

Izzy, Lucas, and Jun have tried to put the hands back on, who is right? So they're all trying to show seven o'clock, but only one of them's right, can you spot it? And the ones that are wrong, can you explain to them how they've gone wrong and where they've gone wrong? Give them some good advice.

Okay, pause a video and have a go.

Who was right then? Let's have a look.

Well, not Izzy.

Izzy's mixed up the hour hand and the minute hand.

Yes, I can see that.

So they are both pointing straight to the numbers as they should, but she's mixed up the hands, so that's not right.

And let's have a look, not Jun either.

Can you see what he's done wrong? He's not been accurate, the hour hand should be pointing directly to seven, not near it, directly on it.

And the minute hand should be pointing directly to 12, not near it.

So that means Lucas is right, the hour hand is pointing directly to seven and the minute hand is directly to 12, so that is exactly seven o'clock.

So very well done to Lucas, and well done to you if you spotted that too.

Izzy's teacher is calling out some times.

Izzy's creating the times on her paper clock, and you might have access to one of those paper clocks too that looks just like this.

And she's going to use a stem sentence to help her.

So that stem sentence again, the hour hand is pointing directly to hmm, and the minute hand is pointing directly to 12, so it is hmm o'clock.

So let's see what the teacher calls out.

10 o'clock.

Okay, Izzy's got to make 10 o'clock using her paper clock.

Let's see what she does.

She's using a paperclip to represent the hour hand, so that shorter hand, paperclips are perfect for that.

She makes sure the hour hand is pointing directly to 10, not near it, just like that.

She's going to use a pencil this time to represent the minute hand, and that's a good choice, because the pencil is going to be longer than the paperclip.

So we've got a short hand and a long hand, or an hour hand and a minute hand.

She makes sure the minute hand is pointing directly to the 12, not near it.

So it's going to be directly pointing to it, just like that.

So she has created the time 10 o'clock with her paperclip and her pencil.

And that stem sentence will be, the hour hand is pointing directly to 10 and the minute hand is pointing directly to 12, so it is 10 o'clock.

Well done, Izzy.

Let's have a check shall we? Using either a mini clock with movable hands, maybe you've got one of those in your classroom or school, or a paper clock that looks just like this one, show the time.

So you can use something like a paperclip and a pencil or something that shortens something that's long.

Say the stem sentence as well.

And the time being called out is eight o'clock.

Pause the video and have a go.

Hmm, did you manage to get that right? Where did you put the minute hand, where did you put the hour hand for eight o'clock? Let's have a look.

Well, if you used a paperclip, the shorter one, that should be pointing directly at eight, just like that.

And if you used a pencil, something longer, it should be pointing directly at 12, just like that.

And that stem sentence, the hour hand is pointing directly to eight and the minute hand is pointing directly to 12, so it is eight o'clock.

Very well done if you've got that.

You're doing very, very well.

I think it's time for some practise.

And I think you are ready for this, because you've been brilliant.

Tick all of the clocks that show the time to the hour.

So I can see lots of clocks, there's six to be precise, but not all of them are showing the correct time to the hour, they're showing different times, which ones are something o'clock? And again, we can use that helpful stem sentence.

And number two, what time do the clocks say? So for the first one, we've given you the o'clock bit, so it's something o'clock.

But for B and C you've got to write the o'clock in yourself.

Okay, so what times are they showing? Have a look where the hour hand is, have a look where the minute hand is.

And for number three, you're going to draw the times on the clocks using both hands.

So the first one's seven o'clock, and you've been given a little bit of help because the dot is right in the centre, but it's not there on B and C, you've got to put it in there, 'cause remember, that's where the hands begin.

So on seven o'clock for A, two o'clock for B, and 11 o'clock for C.

Good luck with that, you've got this.

Pause the video and I'll see you soon.

Welcome back.

How did you get on with that? Let's have some answers.

So the clocks that show the time to the hour.

The first one is this, and we could use this stem sentence.

The hour hand is pointing directly to five and the minute hand is pointing directly to 12, so it is five o'clock.

And there were some others.

The next one was quite tricky, 'cause you can't see both hands, but they're both pointing to 12.

So that's showing 12 o'clock.

And this one, hour hand pointing to eight, minute hand pointing to 12, is eight o'clock.

And the last one is this one, hour hand pointing to 4, minute hand pointing to 12, it is four o'clock.

What time do the clock say? The first one says nine o'clock.

The second one says three o'clock and the third one says ten o'clock.

And in all three cases, because it's o'clock, the minute hand is pointing straight to the 12.

And drawing the times on looks something like this.

So for the first one, seven o'clock, the minute hand's pointing to 12, the hour hand's pointing to seven.

For B, the minute hand's pointing straight to 12 and the hour hand pointing to two.

But make sure that you started those hands in the centre of the clock.

And then for C, minute hand pointing to 12, hour hand pointing to 11, that is 11 o'clock.

You are doing really well so far.

Shall we make a start on cycle two, that's telling the time to the half hour? Have a look at these clocks.

What's the same and what's different about them? Hmm.

Well, I can definitely see something that's the same about them.

I'll give you a clue again, it's the hour hand.

The hour hand on both clocks is pointing to half past one.

The clock on the right is different because it also has a minute hand.

When the minute hand is pointing to six, it is half past the hour, and we're going to practise lots of examples of that.

Half of the hour is gone and half of it is left.

So they're both showing half past one, but the second clock has got a minute hand.

We've got the stem sentence.

The hour hand is halfway between hmm and hmm, it is half past hmm.

And in this case that is the hour hand is half between one and two, it is half past one.

But let's extend that stem sentence.

I'm going to say it, then we'll say it together, then just you.

The hour hand is halfway between hmm and hmm, the minute hand is pointing directly to six, it is half past hmm.

That was a long sentence wasn't it? But let's have another go together.

The hour hand is halfway between hmm and hmm, the minute hand is pointing directly to six, it is half past hmm.

Now let's fill it in.

So in this case the hour hand is halfway between one and what do you think? Two.

And the minute hand, as you can see, is pointing directly to six.

So that big hand's pointing to six.

It is half past one.

The minute hand has travelled halfway round the clock.

Let's do a different one.

Same stem sentence.

What do you think this time? So the hour hand is halfway between hmm and hmm, halfway between two and three.

The minute hand is still pointing directly to six.

So it's half past, what do you think? Shout it out if you know it, half past two.

What about this one? Same sentence.

So this time the hour hand is halfway between hmm and hmm, what and what do you think? Halfway between, shout it out, three and, shout it out, four.

The minute hand is still pointing directly to six, so therefore it's half past, what do you think? Half past three.

Time for a check.

We're going to use a stem sentence to give the time.

There it is, pause the video and have a go.

Did you manage to complete it? Well, let's have a look.

So let's look at the hour hand to start with, that short hand.

The smaller hand, it's halfway between two numbers.

What are those two numbers? Seven and eight.

And the minute hand is pointing directly to six, so it's half past seven.

Very well done if you got that, you are on track.

Let's have a look at this clock.

Is this clock showing half past four? What do you think, and why? Have a little look at it, is that half past four? I don't think it is, do you? No, the minute hand is pointing to seven, not six.

So remember, when it's exactly half past, the minute hand, the long hand, points to six, always.

What about this one? Is the clock showing half past four and why? Hmm, what do you think? Well, it's a little closer to the six, but it's not directly on it is it? So no, the minute hand should be pointing directly to six or straight at that number, and it's not, it's not quite there.

So we can't say that's half past.

Is this clock showing half past four, and why? What do you think? Have a look at the hands.

Hmm, well, there is a hand that's pointing directly to six, but it's not the right one is it? It's supposed to be the minute hand that does that, but the hour hand is pointing to it in this case.

So I think we've got the hands the wrong way round.

The hour hand should be pointing between four and five and the minute hand should be pointing to six, so they're the wrong way round.

Well done if you spotted that.

Is this clock showing half past four? What do you think? Have a look at it.

Does that look like half past four? Yes, it does.

Can you explain why? Let's use our stem sentence.

So the hour hand is halfway between something and something.

It's halfway between four and five.

The minute hand is pointing directly to six still, so that's showing half past, it's half past four.

Let's have a check.

It is half past seven, but the hands have fallen off the clock, oh dear.

Izzy, Lucas, and Jun have tried to put them back on, but only one of them has done it right.

See if you can spot who it is, is it Izzy, is it Lucas, or is it John? Pause the video.

Did you manage to find out which one got it right? Well, let's have a look.

Wasn't Izzy, I'm afraid.

Izzy mixed up the hour hand and the minute hand.

So they were pointing to the right numbers, but the wrong hands.

So good try, Izzy, but not quite right.

And it's not Lucas this time.

He's almost there, he's got his minute hand in the right place but not the hour hand.

Can you spot what's not quite right about it? It's not halfway between seven and eight, so it just needs to move that little bit.

But good try, Lucas, you were close.

And let's have a look at Jun.

Yes, Jun has got it.

Jun's right, the hour hand is halfway between seven and eight, and the minute hand is pointing directly to six.

So he's got it bang on.

Well done, Jun.

Izzy's teacher is calling out times again.

The hour hand is halfway between hmm and hmm, the minute hand is pointing directly to six, it is half past hmm.

So she's going to call out a time.

Let's have a look.

Half past 10.

Izzy makes sure the hour hand is pointing exactly halfway between 10 and 11, because that will show half past.

So there we go, she's using her paperclip to show that, that's representing the hour hand.

So the hour hand's halfway between 10 and 11.

The minute hand is pointing directly to six.

So we need to make sure that we've got a minute hand pointing to six, not near it, but on it.

And we're going to use a pencil for that, 'cause it's longer.

So it's half past 10, and that's how we show half past 10.

Let's have a check.

So using either a mini clock with movable hands, you might have one of those in your school, in your classroom, or a paper clock that's been printed out for you, show the time and say the stem sentence.

So this time the teacher's saying, ready, half past five.

Can you show that on your clock please? Use that stem sentence.

Pause the video.

How did you get on? Let's have a look.

Well, if you had a paperclip, you would've put your paperclip hopefully here.

So halfway between five and six, because it's half past five.

And the minute hand pointing directly to six, that's when we show half past, so it's half past five.

So if your clock looked like that, very well done, you are on track, you're doing really, really well.

Let's do some practise.

Tick all of the clocks that show the time to the half hour.

So some do and some don't.

And there's that stem sentence to help you out.

And number two, what time do these clocks say? Number three, draw the times on the clock using both hands.

So we want a shorter hand for the hour hand and a longer hand for the minute hand.

So you're going to draw half past four, half past nine, and half past six.

Good luck with that.

Pause the video and I'll see you soon for some answers.

Welcome back.

How did you get on with that final set of tasks? Let's have a look.

So using that stem sentence, you might have spotted the first one.

Did show the time to the half hour and the stem centres will be, the hour hand is halfway between 9 and 10, the minute hand is pointing directly to six, so it is half past nine.

And the other ones that showed half past where this one, that's showing half past three, and this one, that one's showing half past 12.

And what time do these clocks say? A says half past 11, B says half past 8, and C says half past 12.

And in all of those cases, the minute hand is pointing to six and the hour hand is halfway between two numbers, exactly halfway.

And then draw the times on the clock.

So A, half past four looks like this.

Half past nine looks like this for B.

And half past six looks like this for C.

So again, make sure your minute hand is pointing to the six, please.

We've come to the end of the lesson.

I've had a lot of fun today learning about this, I hope you have too.

So our lesson has been about telling the time to the hour and half hour using the hour and minute hands.

So that long minute hand points to 12 when it's o'clock and to six when it's half past.

The short hand points directly to a number when it is at o'clock.

And exactly halfway between two numbers when it's half past.

So we've got some examples here.

Look, the first clock is showing three o'clock, so have a look at where the hands are for that.

And the second one is showing half past three.

Very well done on your achievements today.

It's been a great pleasure working with you.

Hope to see you again soon for another maths lesson.

But until then, have a great day, take care, and goodbye.
