Lesson video

Hello.

My name is Mrs. Behan.

And for this lesson, I'm going to be your teacher.

We're going to have a look at digital time.

My watch, shows digital time.

Do you have a watch? Does your watch show analogue time or digital time? By the end of the lesson, whatever digital clock you have in your house or nearby, you will be able to read minutes past on the digital clock.

Let's begin by looking at the lesson agenda.

We're going to start by looking at, the days of the month rhyme.

Then we're going to tell the time on a digital clock.

You're then going to practise reading digital time.

And at the end of the lesson, there will be an independent task for you to have a go at.

Don't worry.

I will go through the answers with you.

I know you are keen to find out how you got on.

You just need two things for this lesson, something to write to with, a pencil or a pen and something to write on.

If you don't have those things to hands now, pause the video here, whilst you go and get them.

Remember, try to work in a place where you aren't going to be disturbed.

Here is the days of the months rhyme, you might be thinking why are we learning rhymes about days of the months.

I don't know if you know but different months have different numbers of days in them.

It's very important we know how many days there are in each month.

We don't make plans for a day that doesn't exist.

I'll tell you now, if you try and make plans for the 30th of February, you will be the only one, because 30th of February is not a time that exists in our calendar.

The rhyme goes like this, 30 days have September, April, June, and November.

31, the others date, except in February, 28, but in a leap year by design, February has 29.

Why does February have one extra day every four years? And a leap year is after every four years.

In one year there are actually 365 and a quarter days.

That quarter is added off after four years to create an extra day.

And because February only has 28 days, we add it onto there.

On a leap year, February has 29 days.

A 29th of February only exists once every four years.

Join in with the rhyme with me.

Let's go.

30 days have September, April, June, and November.

31, the others date, except in February 28, but in a leap year by design, February has 29.

Here's some clocks that I have in my house.

This is an analogue clock.

On the analogue clock, we have two scales to read.

There's this scale here, which tells me the hours that have passed.

And this is the hand that indicates the hours.

There is this also this outer scale here, that tells us the minutes.

You can see a number 60 there to indicate that 60 minutes passes in one hour, and here is an hour, sorry, a minute hand to lets us know how many minutes have passed the hour.

This is a digital clock.

I wear this on my wrist.

This is from my watch.

And in this lesson, we're going to get rid of the analogue clock and we're going to focus on the digital clock.

Very briefly, I'm going to bring back the analogue clock.

And this is because I'd like you to compare the analogue time and the digital time.

What's the same about these two? You've probably noticed that both show the number of hours that have passed and the number of minutes that have passed since that hour.

On the analogue clock, we have this indicator here or this hour hand, that shows us how many hours have passed.

And we have this minute hand here, that shows us how many minutes have passed the hour.

And our digital display, these two digits here, show us the number of hours that have passed.

And this digit here, these two digits here shows the number of minutes that have passed since that hour.

But what's different about with two of them? Just have a little think.

They're quite a few differences between the analogue and the digital clocks.

On a digital clock, only the digits for the current time are visible.

On the analogue clock, if we compare, we can see all of the hours in the AM or the PM.

We can see that there are 12 hours.

We can see all of the display, but here we can only see the hour and the minutes.

That is the current time.

The numbers look different on a digital clock.

You will find that because the digital they're electronic, they look like this.

It is just the way that the clocks are made, and an analogue clock we use hands.

These could be made of plastic that move around.

That the numbers made on the digital clock do look different.

They look a little bit strange.

Any of the differences? What's about the Venus scale on the analogue clock? Like we said, we can see all of the time shown on an analogue clock, we can't see it on a digital, but there is a scale for us to read.

When we reading the minute hands we can count in fives.

This clock here actually shows our clock.

But if the minute hand was pointing over here, we could say five minutes past, 10 minutes past, 15 minutes past, or quarter past.

On the digital clock, we just see the digits.

We would just see number 15 here, if it was quarter past three, because 15 minutes have passed.

It's just something that we have to learn and understand.

There's another difference.

There is a colon on the digital face, and this colon here separates the hours from the minutes.

As I said earlier, these two digits here both represent the hours and here the digital display represents the minutes.

Our focus in this lesson is to look how the minutes change, because that will tell us how many minutes have gone past the hour.

Just like the minute hand tells us how many minutes have gone past the hour over here.

Let's have a go at this.

How many minutes have passed the hour? The hour is five or five o'clock, we can see here, the digit five is shown and the minute shows how many have passed the hour.

13 minutes past the hour.

13 minutes past five.

Can you have a go with the next one? How many minutes past the hour? That's right.

The time shows 20 minutes past 10.

How many minutes past the hour? Can you tell me the time? It is 28 minutes past 11.

We can get creative in the way we say digital time, we can say 11:28, 11:28.

And we understand that that means 28 minutes past 11.

How many minutes past the hour? That's right.

There are seven minutes past the hour.

The time is seven minutes past 11.

How many minutes past the hour? That's right.

19 minutes have passed.

The time is 19 minutes past two.

You are getting the hang of this now.

I'm going to give you some things to have a think about now.

Have a look at the digital clock.

Here is Michael and Michael says the clock shows seven minutes past 10.

The clock shows seven minutes past 10.

But his friend Zara thinks he has made a mistake.

If you were Zara, what would you say to Michael? Pause the video here whilst you have a think.

Take as long as you need and when you're ready, come back to me.

Okay, then.

You've had a bit of time to think.

Michael said the clock shows seven minutes past 10, but can you spot Michael's mistake? Zara said that the clock shows 10 minutes past seven.

Michael has read the hours as minutes.

He said it is seven minutes past 10.

We've got to remember that.

When we read time on a digital clock, we say the minutes first, 10 minutes past seven.

The time is 10 minutes past seven.

We could also say the time is seven 10.

And we understand that that means there are 10 minutes past seven.

You now know enough about digital time to have a go at the independent task.

I'd like you to match the digital and analogue clocks, and then write the time in words.

You can see a digital clock.

You can see an analogue clock, you need to find the matching times.

And then once you've done it, write the time next to the analogue clock.

Write the tiny words here.

Pause the video here to complete your task.

When you're ready, come back to me and we will go through the answers together.

Well done for having a go at your independent task.

Let's see the answers.

Our first clock shows us 13 minutes past five.

It matches up to this analogue clock and in written format, it says thirteen minutes past five.

What's the time on our second clock? Did you work it out? These two clocks match and the time is four minutes past three.

Our next clock, matches it with this analogue clock and the time is nine minutes past twelve.

Here are our last two matching clocks.

And the time reads twenty seven minutes past one.

Well done for completing your independent task.

If you'd like to, please ask your parents or carer to share your work on Instagram, Facebook, or Twitter, tagging at @OakNational, @LauraBehan21 and hashtag #LearnwithOak.

And now we're at the end of our lesson, well done.

You can now read time on a digital clock.

Make sure you look around your house for digital times and practise.

See you again soon.

Bye bye.
