# Lesson video

In progress...

Hi everyone, my name is Miss Sabzvari and I'm really excited that you decided to join me today for our maths lesson.

The unit that we're studying is time.

In today's lesson, we'll focus on knowing how many hours are in one day.

So when you're sitting comfortably and when you're ready, let's begin.

Great, so let's have a look at today's lesson agenda.

First, we'll begin by looking at hours in a day.

Then we'll move on to a talk task.

After that we'll look at analogue clocks and finally, you will complete your independent task.

Before we begin today's lesson, you will need the following items. You'll need a dice and you will need a clock.

Now, if you don't have a clock don't worry.

So please pause the video now and get the items that you need.

Hours in a day.

Have a look at the photographs on your screen.

I would like you to answer the following question.

What time of day might these photos have been taken? Pause the video now and share your answer with the screen.

Great work, so we can see that the first one is easy because we can see that the sky is dark.

So we know that it's nighttime.

And in the second picture, we can see that the sun is either rising or setting, okay? So it's either early in the morning or evening time.

And in the third picture, we can see blue sky.

So we know that it is day time, okay.

So midday, good work.

Have a look at the diagram on your screen, okay.

So we can see that there are lots of clocks around it, okay.

And they all show the number of hours in one day.

So let's count them together and see how many hours are in a day.

Are you're ready? Let's count together.

One, two, three, four, five, six, seven, eight, nine, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24.

So there are 24 hours in one day.

My turn, your turn, there are 24 hours in a day.

Good job, okay.

So what I would like you to do is answer the following question, which hours are day time and which hours are nighttime? Pause the video now and share your answer with the screen, good job.

So we know it's day time when the sun is out and there's light outside and we know it's nighttime when the moon and the stars are out and it's dark, okay.

So day time is around six or seven in the morning all the way to seven or eight o'clock at night and nighttime is from six or seven, or seven or eight o'clock in the evening all the way to six or seven in the morning, okay, good job.

When does a new day begin? Pause the video now and share your answer with the screen.

Good job, so a new day begins.

Normally, a new day begins when we wake up.

But officially, a new day begins at 12 o'clock midnight, okay.

So after that, we're going to the next day.

So 12 o'clock at midnight is when the next day begins.

Do we do the same things every day? And if not, which days might be different? Pause the video now and share your answer with the screen, great work.

So not every day is the same.

From Monday to Friday, we go to school, okay.

Although the structure of the day is similar, the things that happen in the day and the things that we learn are very different.

And two days in the week are very different.

The weekends are Saturday and Sunday are very different because we don't go to school and we do things that we like, okay, so good job.

What time of day do we see the sun? And what time of day do we see the moon and the stars? Pause the video now and share your answer.

Great job, so we see the sun when it's day time, okay.

And we see the moon and stars when it's nighttime, good job.

What I would like you to do is to decide what time would be appropriate for each event, okay? So on the right hand side of the screen, you can see three pictures, okay? And they all have clues as to what time of day they might be.

And what I would like to do is to match them to the clock, so a diagram, whether it's in the morning, noon, afternoon, evening, or nighttime.

And as you're doing this, I would like you to use this sentence structure to tell me why.

How do you know that that is the time that that activity normally happens or takes place? And the sentence structure is, "This person is sleeping so it is nighttime.

You might sleep from eight o'clock at night until seven o'clock in the morning." And when you're ready, we will go through the answers together.

Great job, so as we discussed, we know that this is nighttime.

So this person is sleeping.

So it is nighttime.

So you might sleep from eight o'clock at night until seven o'clock in the morning.

And this person is getting ready for bedtime.

And this normally happens in the evening around eight o'clock at night.

And this person is waking up in the morning.

And this normally happens around seven o'clock in the morning.

Great job if you got all of that correct.

Analogue clock, this is an analogue clock.

So my turn, your turn, analogue clock.

Good job, great job.

So, here we can see some examples of an analogue clock.

What I would like you to do is to pause the video and to tell me how many hours are in one day? Good job, there are 24 hours, okay? But you might wonder that there's only 12 hours marked on a clock.

12 hours are marked in a clock therefore the hands must go around the clock how many times do you think? Tell your screen, good job.

The hands on the clock need to go around the clock twice in one day, okay.

Because if this is 12 midnight, so it's really dark, and we're all fast asleep.

Then it's dark and then it's in the morning we wake up, we get ready.

We're in school, we're having lunch.

And then we're getting ready to come home from school.

It's in the evening.

We're having our dinner.

Then we're going to bed.

And then it's 12 midnight again.

So we go around the clock twice, okay.

So the hands of a clock go round the clock twice in one day because there are how many hours in one day? 24, that's right.

Good job, so have a look at the clock on the screen.

What time is the clock showing? Tell your screen.

Good job, it's three o'clock, okay.

So I know it's three o'clock because the hour hand is pointing to three and the minute hand is pointing to 60.

But how could you tell if it's three o'clock in the morning or if it's three o'clock at nighttime, tell your screen.

Great, so three o'clock in order to know if it's three o'clock in the morning or three o'clock at night, I would look at my window, okay.

So if it's daylight, then I know it's three o'clock daytime and if it's dark outside, I know it's three o'clock nighttime, good job.

What might you be doing at three o'clock in the morning? Pause the video now and tell your screen.

Good job, three o'clock in the morning will be very dark so we'd all be asleep, okay, good work.

And what might you be doing at three o'clock in the afternoon? Great job, so three o'clock in the afternoon we'd be getting ready to finish up with school and getting ready to go home, great work.

What I would like you to do is to roll a dice and to move forward that many hours, okay.

And then you're going to decide on an event that would match the time you have you landed on.

So for instance, you going to roll your dice.

Everybody's going to start on 12 noon, okay, so midday.

You're going to roll your dice and let's say I landed on three, okay.

So I'm going to go one, two, three.

What would I be doing at three o'clock? Day time, I know.

At three o'clock, I would be getting ready with my class to read them a story.

So what might you be doing on a typical day at school? And that's it everyone.

Well done, you have worked extremely hard and you should be very proud of yourselves.
