Lesson video

Hi there.

My name is Mr. Tilstone and I'm a teacher.

I'm going to be working with you on your maths lesson today, which is all about time, and I'm really excited about that too.

So if you're ready, I'm ready, let's begin.

The outcome of today's lesson is, I can tell the time using AM and PM.

Have you heard those words before? They're our keywords.

So my turn AM, your turn.

My turn PM, your turn.

What do they mean? Well, AM is the half of the day from midnight to midday.

And PM is the half of the day from midday to midnight.

Our lesson today is split into two cycles.

The first will be what do AM and PM mean? And the second, telling the time using AM and PM.

So if you're ready, let's start by looking at what do AM and PM mean? In this lesson, you're going to meet Lucas.

Lovely Lucas, he's here to give us a helping hand.

Have a look at this clock, it shows the time that Lucas eats his breakfast.

What time is that? That's seven o'clock.

It also shows the time he brushes his teeth before bed.

Hmm, how's that possible? How can both of those things be true? Well, there are, as you might already know, 12 hours before midday, and there are 12 hours after midday.

There are 24 hours in a day.

Did you know that already? Hmm.

So the 12 hours before midday is also known as AM.

AM stands for Ante Meridiem, you don't need to remember that, but it's a Latin expression, meaning before midday.

So there are 12 hours after midday.

That's also known as PM.

PM, and again, you don't need to remember this, stands for Post Meridiem, a Latin expression meaning after midday.

So when we hear post, it means after.

So the afternoon, after midday.

So we've got AM and PM, 12:00 AM hours, 12:00 PM hours.

So Lucas eats his breakfast at this time in the morning, or AM.

He brushes his teeth at this time before bed in the evening, or PM.

Every time on an analogue clock face could either be AM or PM.

Different activities, parts of the day, and events can be sorted into whether they usually happen in the AM or the PM.

So waking up, what do you think, AM or PM? Shout it out.

That's an AM thing usually, you might wake up in the afternoon if you've had a nap or something, but usually we associate that with the morning, with AM.

Going to school, going to school, AM or PM? Shout it.

Hmm, another AM one, that's another morning one, usually.

Coming home from school, which one, AM or PM? Well, that happens after lunch, doesn't it? After midday, so that's a PM one, that's an afternoon one.

Eating dinner, hmm.

So when you come home from school, a bit later on, you'll have your dinner, is that AM or PM? That's another PM one.

Midday itself, now that's quite tricky.

Have a think about this one.

You think midday happens in the morning, AM, or does it happen after midday? Is it PM? Hmm.

Well, it's actually PM.

It is the very start of the afternoon.

The very start of the afternoon is called midday, and that is PM.

Midnight, what do you think? Is that an AM or PM one? You might be surprised.

It's actually an AM one.

People associate midnight with darkness and that kind of thing, but it's the very start of a new day.

So it's AM, so midnight and midday are quite tricky ones.

It's 12:00 AM, it's the very start of the morning or AM.

Let's have a check, join the event to the time it's most likely to happen.

So breakfast, bedtime, lunchtime, and start of school, for each of those, say, is it AM or PM? Pause the video.

Welcome back, how did you get on? Let's have a look.

So breakfast, that's an AM, that's a morning activity.

Bedtime usually PM.

Lunchtime is PM, just it's the very start of PM, and start of school is AM usually.

Time for some independent practise.

So number one, complete the sentences, the time before midday is called mm.

And the time after midday is called mm.

So think about what we're learning about today, there's a clue in the title.

Number two, join the event to the most appropriate times.

So we've got midday, midnight, waking up, and end of school, for each of those is it AM or PM, just like in the check for understanding.

And number three, think about things that happen in your lives such as lessons, clubs, meal times, and other daily routines.

And write them in the circles.

So all the things you can think of that are AM, and all the things you can think of that are PM.

Good luck with that and I'll see you soon for some feedback.

Welcome back.

Let us have some feedback.

So complete the sentences, the time before midday is called AM and the time after midday is called PM.

And those are the facts I want you to come away from this lesson knowing.

Match the event to the most appropriate time, midnight is AM, the start of AM in fact.

Midday is PM, the start of PM, waking up usually AM, and end of school, usually PM.

And then lots of things you could have put in the AM and PM circles, but for example, AM you might have put brushing my teeth before school, maths lesson, maybe that's something that normally happens in the morning for you, maybe.

Morning playtime, do you have one of those? And for the PM ones maybe you have a bedtime story, that would be a PM thing, wouldn't it? A gymnastics club perhaps.

Perhaps you do that after school or at the weekends or something.

And homework, maybe that's something you do in the PM.

Our next cycle is telling the time using AM and PM.

When giving time, using AM or PM, you do not need to say, "o'clock".

So for example, you'd say 12:00 AM, 1:00 AM, 2:00 AM, 3:00 AM, say it along with me, will you? 4:00 AM, 5:00 AM, 6:00 AM, 7:00 AM.

Now Lucas has his breakfast at 7:00 AM or seven o'clock in the morning, remember? Let's keep going.

8:00 AM, 9:00 AM, 10:00 AM, 11:00 AM.

So people aren't saying 11:00 o'clock AM, it's just 11:00 AM.

It's now midday, so the time switches to PM, remember, as soon as it's midday, it turns from AM to PM.

So we've got 12:00 PM, say along with me, 1:00 PM, 2:00 PM, 3:00 PM, 4:00 PM, 5:00 PM, 6:00 PM, Lucas brushes his teeth for bed at 7:00 PM, or seven o'clock in the evening.

Let's keep going.

8:00 PM, 9:00 PM, 10:00 PM, hopefully you are in bed by this point.

11:00 PM, and then it'll be midnight again, a new day.

The train to Manchester sets off at nine o'clock.

Can you see why that information could be a little bit confusing? Well, because there are two nine o'clocks every day.

Nine o'clock happens twice a day.

So we need to know which one.

It's not clear whether this is the morning or the evening.

So you could end up turning up at the wrong time and either missing it or being really, really early.

So using AM and PM definitely helps.

So the train to Manchester sets off at 9:00 AM.

"That's clearer", says Lucas, it is, isn't it? We get it now.

Lucas is describing his day using AM and PM, and he's going to give us some approximate times, some rough times that he does different things in his day.

He says, I usually wake up just before 7:00 AM.

You can see that on the clock.

I usually have a shower at 7:00 AM.

I usually have breakfast at 8:00 AM.

The school day at Oak Academy starts at 9:00 AM.

You can see that on the clock and it's specifying that it's AM.

There is an assembly most days just after 9:00 AM.

Lunch is at 12:00 PM.

I walk home with my dad at 3:00 PM.

I do my homework just before 4:00 PM.

After that we take our dog, Oakley for a walk, it's usually about 4:00 PM.

Mom usually gets him from work at about 5:00 PM, that's when we have dinner.

I brush my teeth just before 7:00 PM.

Bedtime is usually 7:00 PM.

So he's described his day using AM and PM, as well as the o'clock times.

Time for a check.

Match the event to the time it's most likely to happen.

So we've got breakfast, bedtime, lunchtime, and start of school.

And your options are 7:00 PM, 12:00 PM, 9:00 AM, 7:00 AM.

Pause the video.

Let's have a look.

So breakfast is 7:00 AM, bedtime 7:00 PM, lunchtime 12:00 PM and start of school 9:00 AM.

And of course that's not the time those things always are, but they were the most sensible kind of rough estimates.

Okay, time for some more practise.

Complete the sequences, 9:00 AM, 10:00 AM, 11:00 AM, mm, mm.

And then for B, 9:00 PM, 10:00 PM, 11:00 PM, mm, mm.

They're quite tricky.

Have a good think about what you know.

And then number two, write or draw, doesn't matter, a story about a typical day for you.

And it could be a weekday or a weekend day.

So we heard about a typical day for Lucas.

What about you? Use AM and PM alongside the o'clock time, just like Lucas did.

So for example, you might start by saying, I'll wake up around 7:00 AM.

Pause the video, best of luck, and I'll see you soon for some feedback.

Welcome back.

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

So the sequences go 9:00 AM, 10:00 AM, 11:00 AM, 12:00 PM, that's the start of the afternoon, 1:00 PM.

And then B, 9:00 PM, 10:00 PM, 11:00 PM, what's next? 12:00 AM, that's the very start of a new day, also known as midnight.

And then 1:00 AM.

Well done if you've got those.

And then you're telling your story about things that happened to you.

So for example, a typical Saturday, might go as follows, I set my alarm for 7:00 AM, have a breakfast around 8:00 AM, I usually have a shower at about 9:00 AM, football practise starts at 10:00 AM, and finishes at 11:00 AM.

We go to have lunch at Gran's house, usually about 12:00 PM.

Have an art class at 3:00 PM.

Dinner's usually about 5:00 PM.

Often we watch a film as a family at about 6:00 PM.

Bedtime on Saturday is a little bit later than usual at 8:00 PM at the latest.

So that's just an example of using AM and PM alongside o'clock times.

We've come to the end of the lesson, so you've been learning all about AM and PM.

So in summary, the time before midday is called AM, and the time after midday is PM.

Those are the facts that you need to know before you leave this lesson.

In this example, there are two different eight o'clocks in every day, so using AM or PM helps you to know which one it is.

It's been a huge pleasure working with you today.

I really hope I get the chance to work with you again in another maths lesson in the near future.

But in the meantime, take care.

Enjoy the rest of your day, whatever you've got in store, and I'll see you soon.

Bye-Bye.
