Hi, my name is Mrs Behan and for this lesson, I will be your teacher.
I am wearing my watch and that's so I can keep an eye on the time.
I believe you are good at telling the time, to the hour, quarter past, half past and quarter to, well, after this lesson, you'll be able to tell the time on an analogue clock to the nearest minute.
Let's take a look at the lesson agenda.
We're going to start this lesson with a spot the mistake activity.
Then, I'm going to teach you to read the scale to the nearest minute.
After that, there will be a practise activity and then you'll be ready to do an independent task.
And don't worry, I will go through the answers with you, I know you'll be keen to find out how you got on.
There are just two things you will need to take part in the lesson, you will need a pencil or a pen and something to write on, like some paper.
If you don't have those things to hand, pause the video now, whilst you go and get them.
Remember to try and work somewhere quiet, where you won't be disturbed.
So, it's time for you to show me how good you are at reading time to the nearest five minutes.
On your screen, you will see a picture of a clock, it will flash up and all you have to do is call out the time to me.
Are you ready? Let's go.
The time is quarter past one.
The time is half past three.
The time is half past 11.
I'm just going to say, if you think we're going too quickly, just pause the video as soon as I've shown you the clock, to give you more time to think, then press play again to join in.
The time is quarter to one.
The time is 10 past 12.
The time is 25 past 10.
The time is 20 to nine.
Well done, I'm sure you did a brilliant job there.
Okay, onto our spot the mistake activity.
So, here is a picture of a clock, have a look at the time.
I'm going to read these statements to you and then I want you to pause the video and work out what has gone wrong.
The minute hand indicates four past.
The hour hand indicates between two o'clock and three o'clock.
Therefore, I know the time is four past two.
Pause the video here, whilst you work out what the mistake is and what you would do to put it right.
Okay, let's go through it then.
So, where is the mistake? At what point did this person, writing these statements, make the mistake? That's right, they said that it was four past, it's not four past, is it? Even though this hand here is pointing at number four, is that the hour hand? No, that is the minute hand.
So, what have they done? The mistake they've made is they've read the wrong scale, they should be reading for the minutes where the blue hand goes round, the scale on the outside of the clock that goes round in fives.
Let's count from the top, five minutes, 10 minutes, 15 minutes, 20 minutes.
So, that's the mistake, they should have used the scale on the minute hand to work out that actually the time is 20 past two.
Okay, let's remind ourselves of the different types of clocks.
So, here is my wall clock, that's not actually on the wall at the moment in my house, we call this type of clock, an analogue clock, where we can see our whole clock face and it has two indicators.
One indicates the hours that have passed in the day and one indicates the number of minutes that have passed in the day.
And this here is my digital watch, so we just have hours and minutes displayed with no hands at all, it just tells us how many minutes have passed the hour.
Today, we're just going to be focusing again on the analogue clock.
So, tell me what this is.
That's right, this is the unravelled minute scale, so around the clock, we saw two scales, one that showed us the hours and one that showed us the minutes and we've taken it off and we've laid it out into a line, so it now just looks like a number line.
So, it stops at 60, so this is the minute scale.
Practise reading this scale with me.
So, now it is at 20, so if it was on the clock, it would be 20 minutes past.
What would it be now? 30 minutes past, well done.
Now, it would just be five minutes past.
Oh, so we've now got a division here, it doesn't have a number on it but can we work it out? If each of these divisions goes up in fives, in these large intervals, what are these small markers worth? What's the value of each one? Well, this would be 10, there's four in between and this would be the fifth one, so I'm thinking these are going to go up in ones.
So, all we have to do is say the number one after, so if this one was 10, this is 11.
So, on the clock, this would be 11 minutes past because it is one marker past 10 past.
Let's try another one.
Ooh, look at this one more carefully.
40, 41, 42, so on the clock, this would be 42 minutes past.
Do we have another one? We do.
Okay, I know an easier way of working this one out, a more efficient way, I can look at 55 and actually I'm going to go back one, now, the clock doesn't go back but to help me work it out more efficiently and quickly, I can think, right, well, it's actually only one minute away from 55 minutes past, so this would be 54 minutes past the hour.
Well, let's have a practise now at reading the times on these clocks.
Tell me the time that you can see.
You should be telling me that it is one minute past two.
This time it is two minutes past two, three minutes past two, four minutes past two, five minutes past two, six minutes past two, seven minutes past two, eight minutes past two, nine minutes past two, 10 minutes past.
I would now like you to have a go at reading the time to the nearest minute on these clocks.
Pause the video here whilst you have a go and then when you're ready, come back to me and we will go through the answers together.
Okay, well done for having a go.
Did you manage to get that 21 minutes past one was the time on the first clock? We know that we've passed five, 10, 15, 20 minutes past the hour and one more is 21 minutes past the hour.
Our second clock shows 26 minutes past 10, the minute hand would have started up here at 10 o'clock, then we've gone five minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes past 10 and one more minute is 26 minutes past 10.
And what's the time on our final clock? That's right, our final clock shows seven minutes past 12, so the clock would have started up here, the minute hand would have started up here, then it would have passed five minutes, six, seven minutes, well done.
You'll need your thinking caps on for the next part of the lesson, it's going to get a little bit trickier.
Okay, but you have already been able to read times to the nearest minute past the hour, now we need to learn to read time to the hour to the nearest minute.
So, for this, we need our minute scale.
Why is 60 at the end? Let's remind ourselves that there are 60 minutes in one hour, so once our minute hand has reached 60, it's actually back at the o'clock position and it's going to start counting round in intervals of one again.
So, we are going to think about how far away our minute hand is away from 60.
So, we're going to look at the distance between the minute hand and 60.
Let's take a look.
So, here I have used my pink arrow as a minute hand and it's at 55, what's the difference between 55 and 60? The difference is five, so the arrow is five places away, it's five minutes away from 60.
So, for this, we could say the time is five to the next hour.
Here, we can say the time is 10 minutes to the next hour because 50 is 10 away from 60.
The arrow now is 25 minutes to the next hour and that's because it's 25 steps away from 60.
Well, this now here, this is one minute away, so it's very, very, very close, so it's before the hour changes, it's the last minute before the hour changes as well, so one minute to the next hour.
I'm backwards then instead of forwards, let's try again.
Can you work out where two minutes to the next hour would be? You've just seen where one minute to the next hour would be, so where would two minutes to the next hour be? That's right, it would be here, it seems strange that it goes further back but we've increased the distance away from the full hour, so this position is two minutes to the next hour.
Let's put your new learning to the test.
What time does the clock show, that you can see on your screen? That's right, it's just one minute to two because the gap between the minute hand and the next hour is just one, so it's one minute to two.
What's the time on this clock? This clock shows nine minutes to two, sorry, nine minutes to three, we've got to check the hour hand as well.
So, nine minutes to three and that's because the gap between this point here, the minute hand, and the hour, so the change of the hour, that gap is nine minutes.
Don't get confused saying 11 because this is 10 and this would be one more, it's not, when you're going to the next hour you're looking at the gap between the minute hand and o'clock.
What does this time show us? That's right, it's 21 minutes to three, I made sure I checked the hour hand that time.
So, 21 minutes to three because we are 20 minutes away, five, 10, 15, 20, to get to this point and one more minute further away is 21.
So, the time is 21 minutes to three.
You've now got the skills and knowledge ready to complete the independent task.
Use what you have learned so far in this unit to help you tell the time to the nearest minute.
Remember to be careful about how you count the minutes to times as these can be slightly trickier than minutes past times.
So, here are some clocks and on the blank spaces all you have to do is write the time.
Pause the video whilst you complete your task.
Once you've finished, come back to me and we'll go through the answers together.
Okay, so let's look at a, so a, the time is 19 minutes past 12, the hour hand is between 12 and one, so we know it has gone past 12 but not gotten to one and we're actually just 19 minutes past 12, we've not quite reached 20 past yet.
This clock here shows seven minutes past seven, the hour hand is past seven and it's on its way to eight but we've passed five minutes, six minutes, seven minutes past seven.
Our third clock shows 30 minutes to eight, so our hour hand is nearly at eight, it's not there yet, but it's nearly at eight and the gap between the minute hand and the next hour is 13 minutes.
Let's look at d, d shows us 27 minutes to four, so our hour hand is on its way past three, it's just after halfway and we've got 27 minutes to four because we are 25 minutes away, going this way, 26, 27, we are 27 minutes away from four o'clock.
This time shows us six minutes to 12 because our hour hand is pointing at 12, so we're nearly at 12 o'clock but we have five and one more, six minutes yet to go, so the time is six minutes to 12.
And for f, the clock shows us 13 minutes past six, the hour hand is past six o'clock and it's on its way to seven, but up here, we've past 10 minutes, so five, 10, and three more, is 13 minutes past six.

You have worked so hard this lesson, it's not been easy, you should be very proud of yourself.
I'm sure now you're going to go around the house and look at analogue clocks and practise reading the time and so you should.
See you again soon.
Bye-bye.
