Lesson video

Hey everyone, and welcome back to Oak National Academy with me, Mr. Ward, as we continue our unit on line graphs and timetables.

Now, today we're going to be reading timetables and looking specifically at the skills required to accurately interpret the information on those timetables.

Now, I need you to be ready for the lesson by making sure you're in a quiet space, all the equipment that you need, and are free of distraction.

When you are ready to begin continue the video.

See you in a few minutes.

Hello everyone.

And welcome to those that are new to Oak National Academy or new to lessons taught by myself, Mr. Ward.

And those of you who have watched previous lessons on the unit line graphs and timetables, will know that I like to start my lessons with a maths joke to put a smile on your face and get you relaxed and ready for the work ahead.

So today's maths lesson is this, why do some pupils not consider statistics amongst their favourite maths sessions? Apparently there are too many average lessons.

Now, if you're sitting at home and you have not cracked a smile at that joke, I consider you to be mean if you do not find the joke about average funny.

Mean, average, get it? If you don't, you could always ask your maths teacher next time you see them.

As you can see, outline of today's lesson, we're going to start by introducing the concept of timetables and what we use them for.

Then we're going to spend a little bit of time on a talk task, interpreting a timetable and identifying the information from it.

You can always pause the video at any point to take more time to discuss or to reflect or to have a go at the activities.

Then we're going to develop our learning a bit further by looking at the additional information that is required in a timetable.

And then it'll be over to you, you're going to have a go on an independent task in using timetables and interpreting the information accurately within them.

And then, as always, as a custom here at Oak National Academy, we're going to ask you to end the lesson by having a go at the quiz by demonstrating all the information and learning that has taken place across the lesson.

In order to be ready to learn, you've got to make sure you need all the equipment that you can see on your screen.

So, a pencil is ideal to record work on.

A ruler and some pieces of paper or a notebook that has been provided to you by your school.

A rubber is optional and is perfectly acceptable.

In fact, it's perfectly preferable for you to not spend lots of time rubbing out work, but just pull a line through your work to show that you've identified that you made a mistake and you've got a misconception, and that you've learned how it's right and why it's right, and that indicates your mathematical learning.

Okay, we can begin today's lesson by looking at these images that are connected by the same mathematical words.

Spend a few moments looking at these images and try to envisage and imagine what the words are that I'm looking for.

Now, the words connected to these images are very important within our learning and use of timetables today.

Pause it here if you need to, or if you're ready to continue, we will look at what I was imagining and see if you've got the same words listed.

The first word was column.

Now, you can see there's a picture of Nelson's Column in Trafalgar Square but also you might recognise from history lessons in your school from Ancient Egypt or Ancient Rome, the use of columns to hold buildings.

The second word is rows.

You can see there's a row of ducks, a row of houses, a row of medals, and a row of icicles hanging down.

Now, it's summertime at the moment so it's a long way off till I start seeing icicles, but it just made me feel shiver a little bit, a little bit of coldness.

And finally, they are in order.

And we have something called ordinal numbers, and this is the word I think you may not have picked up on.

Now, often we use digits in order, don't we? Like a sequence or going up one, two, three, four.

And when that happens, we can call them ordinal numbers.

Now, we don't use that term very often, but you don't need to be worried if you come across the word ordinal numbers, 'cause it just means that the digits are presented in an order, and that often happens in timetables, doesn't it really? When we think of what comes first then next, you know, trains and buses that we use timetables for, come in order, in a sequence.

So the term ordinal numbers means the order of the numbers.

So what is a timetable specifically? And how many different examples can you think of from the world around us? Now, a timetable gives us information about what's going to happen in order over a period of time.

So, it allows us to put things in sequence, it allows us to plan, it allows us to see what's going to happen when and in what order.

Some examples you may have thought of and we use in everyday life, a bus or train timetable telling us the time of the next bus or the next train, the time that the bus is expected to arrive at a station, how long the bus might take to get from one location to another.

A schedule or diary.

It allows you to put in when you might have meetings or lessons or events.

It's invaluable as a teacher to be able to put in all the lessons that I've got and all the meetings I have to do.

Out of work I'm sure you've got something similar, a diary or a calendar are also very similar.

And a third thing I imagine is when I go on a holiday, I often stand staring at the board wondering why my plane has been delayed, delayed, delayed.

Now, boards can be quite complicated when there's a lot of information on there and that's why we do need the skills today to be able to circumnavigate the board, find the correct information that we want, because often in a timetable, there's lots of information that's not relevant to us, it's not important.

So for instance, if you're using an airport timetable or schedule on the board you want to find your flight, your time and what time it's going to take off or land.

So, you don't need all the rest of the information.

So you need to get to pick out the information that you need by knowing exactly where to look.

So, on your screen you should be presented with a timetable as such that has all manner of information on it.

Spend a few moments looking at this schedule.

Try and find out what information do you think you've been presented.

Pause the video if you need to.

Just spend a couple of moments looking closely at the screen.

Now, on first glance, there's a lot of information there.

It's not surprising that you would become overwhelmed or confused.

Not quite necessarily knowing what you're looking for, what you need to know.

So, in order to do so, we need to explore what this schedule is showing us.

First of all, we've got a title of course, the Olympic schedule, Rio 2016.

And there's a key at the top.

And the key says that where it says E, it's an event, and where it has a gold box with a number inside, tells you it's gold medal event.

And we can presume that the number inside that box shows the number of gold medal events on that day.

There are labels, as always the case when we look at timetable or graph, there's labels down one side, and these have been presented in the form of an image.

And those image and the words tells us the specific sport that's taking place.

So, athletics, cycling, rowing, swimming, synchronised swimming, and weightlifting.

Finally, we have some dates along the top.

So often we're used to graphs having an x-axis at the bottom.

In this instance, on the timetable, the information that goes across, it's at the top of our schedule.

And we can see that it has the day and the date underneath it.

So, this schedule is showing us the number of events and gold medal events that are taking place in a specific sport on a specific day across the Olympic schedule for Rio.

And we can use the information within that to answer a series of questions that might be presented to us.

There's an example on the board.

I mean board, I'm still in classroom mode.

There's an example on the screen.

On what day was there three gold medal events in cycling? Pause the video if you need a few moments to find it.

If not, let's look at it together.

Now, we know that we're looking for cycling.

So we need to come across and find the correct column, which is over here where the sports are listed.

Then we need to identify where cycling is, and we need to use the correct row, so we're going across our row now.

Now we know from the key, that we're looking for a gold square or rectangle in this case, we're looking for a gold square, 'cause that's going to tell us the difference between a gold medal event, a normal event, just a normal event or race, and the blank squares where nothing's happening on those days, there's nothing in there.

So, we're looking for one of these gold rectangle shapes, and we're looking for three gold medal events, and I go across I can see 2, 1, 1, 2, 2, and then finally I find three.

I'll just check there's no other three on that row.

There's nothing along here, so this must be the only one.

Therefore, I know that cycling got three gold medal events on Tuesday the 16th of August in Rio.

And that's how I've identified and used that information.

So, previously I mentioned how timetables often have a lot of information that's not relevant to us for our specific need, and we can see that here.

So, there's all this information about all different events, and all different sports across the Rio Olympics.

And actually we only needed to find that information from one particular row and one particular column.

So, it's about being able to identify relevant information with irrelevant information, but we've been asked to do that and identifying it and find the answer to our question.

We're now onto the talk task part of today's lesson.

Now, usually talk task are done within schools in pairs, small groups or a whole class, but you may be working on your own.

Not to worry you can still take part in this part of the lesson, by pausing the video and spending some time having a go at the task in hand.

Alternatively, if you can find an adult pair or carer or sibling nearby, get them over, show them the mass on screen, and try have a discussion about the information that is there as part of the talk task.

There's your task on screen.

Once I've finished the instructions, I'd like you to pause the video and spend as long as you need completing the task.

Read and interpret the timetable to answer the questions.

You can see that the timetable is about the Olympic schedule in Rio in 2016, as we've been looking at.

There are three questions for you to answer and you need to read and interpret the information that exists within that schedule.

I've enlarged the schedule so you can see clearly on your screen.

Pause the video now, have a go at the task, take as long as you need.

And then when you're ready to resume the lesson, come back to us and we can look at the answers together, best of luck for now.

Welcome back everybody.

Let's spend a few moments looking at the answers.

So in order to find out the total number of gold medal events in each sport, we had to go across the correct column.

So in this case athletics, find where it's a gold medal event, and then count and add the total amount per column.

So in this case, three plus five plus four plus five plus five, etc.

This gave us a total of 47 for athletics.

18 for cycling.

14 for rowing.

34 in swimming.

Only two in synchronised swimming, and finally 15 in weightlifting.

I did additional extra, I added all of those metals together, gold medal events, and I got a total of 130 gold medal events taking place across the Rio Olympics.

The next two questions, across how many days do the events take place? The answer is 16 days.

Now one misconception may have been 15, because 21 takeaway six is 15, but we're not looking purely as a calculation, we're looking at time.

So, if I started on Saturday, there was an event on the Saturday.

If we go seven days takes us to Friday, the eighth day is another Saturday.

So, seven, eight, and on the seventh day it takes us to the next Friday.

And that's already two weeks, a fortnight, 14 days.

And then there are of course, two extra days, Saturday and Sunday, so the answer is 16 days, not 15 is I think may be a mistake some people made at home.

And finally, on what days do the most gold medal events happen? They are Friday the 12th, where there are 15 across five events.

And on the 13th, Saturday, there are 16 gold medal events, five in athletics, four in rowing and swimming, two in cycling and one weightlifting.

So between Friday and Saturday, there are 31 gold medal events taking place on those two days.

Okay, I'm going to ask you now to imagine if you will, that you worked for the Olympic schedule in Rio 2016.

And you work in the office, and people can ring or email you to ask and request information about the events in order to book tickets.

Now you receive an email from a young man who says, I would like to see water events, I'm free on the weekend of the 13th, what are my options? And you need to compose an email, and offer some advice on the information that it contained in our schedule.

So in order to email back, we need to identify first of all, the weekend of the 13th.

So we're looking at the events that take place on Saturday 13th or Sunday the 14th.

Now he's looking to see water events.

So you need to go down both sides, we need to identify first of all, which are the water events, well, not athletics, not cycling, rowing, yes, there are water events there.

Swimming, yes there are.

There are no events in synchronised swimming and weightlifting is not water-based.

So on Saturday we can say there are two possible events he can attend, where there will be eight gold medal events taking place in rowing and swimming.

And then we look at Sunday.

Again, no athletics, no cycling.

There's nothing happening in rowing.

And there's nothing happening in swimming.

And there's one event, that is not gold metal related, it's just an event in synchronised swimming on this Sunday.

So what advice would you be providing to this person? Well, I would probably advise that they come on Saturday the 13th, where there are eight gold medal events taking place in two events, in rowing and swimming.

I think they'll get their money's worth then.

If there were to come on the Sunday where they're available, all they would see is one water-based event, and it won't be a gold medal.

That would be my advice to them, okay? And I've used my timetable by going across the correct rows and columns to identify specifically the information that's going to help me respond to that specific request.

Okay, you get another email from somebody else, it says I'm very keen to see all the events taking place on the same day.

Well, they want to get their money's worth, they certainly do, don't they? What day off should I ask for from work? Okay, I know this problem, I want some time off sometimes and I need to ask in advance.

So it's important they have that information, and you've got the schedule.

So, all of the events on the same day.

Now, let's see if that's actually possible.

Remember, when we're looking across, these blank boxes mean there's nothing happening in that.

So there's nothing happening in athletics the first six days, okay? So we don't need to look down here.

Actually when I look down, I don't see, so on Saturday, there's nothing in athletics or synchronised swimming.

Sunday, same again, athletics, there's nothing happening till here.

So let's start looking from Friday the 12th.

I can see actually, synchronised swimming they're not there either.

Okay, so when I look down the columns, I don't actually see a column where there is an event in every single sport on the same day.

However, there are several days where all but one sports are taking place.

On Tuesday the 16th, everything but rowing is taking place, so we could suggest that.

On Monday the 15th, everything but rowing again.

However, synchronised swimming only has an event, not a gold medal event.

And if I look across at Saturday the 13th and Friday the 12th, there are events in everything but synchronised swimming.

In fact, Saturday the 13th and Friday the 12th, are when the most amount of gold medal events are taking place as well.

So what would our advice be to this person? We would have to say sorry, there are no days in our schedule so far where there are all events on every single day.

However, there are four days when there are five out of the six events taking place.

Saturday the 13th, Friday the 12th, Monday the 15th and Tuesday the 16th.

But we recommend that you come along on Saturday the 13th, because that is when the most amount of gold medals events are taking place.

So, I'm going to give you top tip now 'cause you can see we've enlarged in the table, there's actually a lot more than those six events taking place in the Olympic games.

And we've enlarged in the schedule to see a range of sports now, a range of events that take place across the same time periods, so still the 16 days of the Olympics, and you can see down the left-hand side, there's now a lot more sports.

Now no longer do we have the images, we've only got the words to represent each of the events and sports.

However, I'm going to give you a top tip to make it easy to digest that information, to break it into chunks.

Why not subdivide it to categories, especially if you're trying to find specific information about specific events.

So I've got three specific categories here that's going to help me narrow down for any questions I might get.

I've got one that has the events that involve a ball of some sort.

I can see seven there are events that involve a ball.

I almost put badminton in, but badminton has a shuttlecock not a ball, so I decided I wasn't going to include it in my category.

Then there was combat sports.

There's boxing, there's fencing and there's judo.

And finally there's water sports, canoeing, diving, sailing, and swimming.

So now that I've broken out all that information on the left-hand side into subcategories, it makes my job of trying to interpret and find specific information a lot easier when I'm given specific instructions.

All right, so now that we've spent time looking at the events timetable, both the smaller and the enlarged timetable, you're going to have an opportunity now to try to demonstrate your understanding by having a go at the independent task.

What you need to do is imagine that you are working for the Olympic company, dealing with customer questions and queries.

I would like you to use the events timetable, to provide accurate information in an email response to the questions posed by the four people below.

As you can see all the events and all the number of events going on are listed within the timetable as discussed previously in the lesson.

Take your time to interpret the information, and be very careful when looking through the correct rows and columns to identify exactly the information that you require.

There are four requests here from people that want further information in order to book their tickets.

You are going to have to find the information to respond to them by email, with all the information and details requested.

Now because this is an open task, we're not going to share our answers today within the lesson.

However, as it's custom here at Oak National Academy, you can send in evidence of your work to us via Twitter, with the permission of your parent and carer.

Details of how to share your work will be given at the end of this lesson, so please keep watching.

There is no time limit to complete the task you're going to pause the video and take as long as you need to complete this task to the best of your ability.

Once you feel you've finished the working, done the best you can do, you can move on to resume the video and we'll finish the lesson together.

See you all very soon.

Welcome back everyone, and I hope you enjoyed completing that task, and were able to interpret the right information that was hidden within the events timetable.

For those that would like to extend themselves a little bit further and continue their learning during the lesson, I've included another challenge slide for you to have a go at.

You'll have to pause the video and read the instructions if you want to have a go.

Again, there is no time limit and you can keep coming back to this challenge slide, as much as you need.

That almost brings us to the end of the lesson.

Thank you once again for your focus and efforts, it was a really good lesson, I've really enjoyed it.

But now it's time for you to have a go at the end of lesson quiz, to see how much of that information has been embedded, and just how confident you are moving forward on timetables.

Just time for me to remind you once again that it is possible to share some of that brilliant work that you've been completing at home, or sending in some of your fantastic jokes to help improve my material, and let's be honest, it needs improving, doesn't it really? So if you'd like to do so and share that work and those jokes with us here at Oak National Academy, please ask your parent or carer to share your work on Twitter, tagging @OakNational and #LearnwithOak.

I look forward to seeing what you've been producing at home.

So, that brings us to the end of another lesson here on Oak National Academy.

Thank you for your hard work and focus today.

I'm really confident now that none of you are going to be stepping on the wrong bus or train at the wrong time in the near future.

If you would like to watch any previous lessons that have been recorded for the unit line graphs and timetable, you can find them on Oak National Academy.

I look forward to seeing you soon here for another lesson on Oak National Academy, so we can learn together and tell some more terrible, terrible math jokes.

So, for now, from me, Mr. Ward, have a great rest of the day and I'll see you soon.

Bye everybody.
