Lesson video

Hi everybody and welcome back to your unit all about place value.

Today we are going to be all doing and comparing three digit numbers and there's a really fun song that we can sing about the alligator.

But before we even begin, let's put on our hats, tighten our ties, tell the computer now I'm a mathematician! Now you may have heard this alligator song before either at school, or somewhere else but lets sing it together.

Alligator, alligator which one will you eat? The bigger one, the greater one, it will be sweet! Remember, alligator jaws are always going to be going towards the bigger number as its a greedy alligator.

So, I'm really looking forward to this lesson with you, so let's get started.

So here is our lesson agenda for today.

First off, we're going to be using our star words, then we're going to be comparing three digit numbers, before moving on to use a number line, and then we're going to be looking at Blackpool Beach Leisure, Blackpool Leisure Beach, visitor numbers, before moving on to your independent task.

But before we begin, you need to make sure you have a pencil, paper, ruler, access to a dice, or an online dice, so if you need to pause the video to get any of those resources, please do now.

Brilliant, let's get started.

Here are star words! Remember to repeat them back, star words! Greater than, less than more fewer hundreds tens ones.

Brilliant remember to use our star words throughout our lesson.

And if you see that I'm not using them, make sure to whisper to the screen, "Miss Hill, you're not using your star words!".

Great job, let's get started.

So here we have some comparing.

So we need to compare these numbers using our alligators, our equal sign.

Now remember, alligator likes to eat the bigger of the numbers, so here we have eight hundred and ninety one, two hundred and sixty one.

Can you point to which number our alligator is going to be facing? Great job, he's going to be facing eight hundred and ninety one.

How about this second one? I'm not going to say the numbers this time.

Well done, I hope you're pointing to nine hundred and two, as nine hundred and two is greater than two hundred and thirty seven.

How about this final one? Point to the greater one.

Lovely job, you should've pointed to eight hundred and seventeen, as eight hundred and seventeen is greater than, thirty six.

Here we have two numbers, what's the same? And what's different? Hmm, have a think what is different about those numbers and what's the same? So we're going to draw a place value chart and put each number into a place value chart, so here I have my place value chart, you can see I have my hundreds, my tens column, and my ones column.

So I'm going to quickly write both of those numbers, we have three hundred and five, and four hundred and seven.

So you can see, that they have different hundreds, they have different values of hundreds, and they have different ones.

But their tens are the same, neither of these numbers have anything in their tens column.

So where would you place these on a number line and why? Pause the video, and have a think, where would you put three hundred and five and four hundred and seven? Hmm, so, I can see that on my number line it starts at two hundred and it ends in five hundred so what I would do, is I know I need to put three hundred in, and four hundred in.

So they are somewhere on that line.

You can see I've put three hundred more towards two hundred than five hundred, and four hundred more towards five hundred than two hundred, so where would we put those numbers? Well three hundred and five is much closer to three hundred and four hundred and seven is much closer, to four hundred.

Hmm, here's a challenge for you, where would three hundred and forty five go? Point to the screen where you think three hundred and forty five would go.

Lovely, so what I've done to help myself a little bit, is I know that three hundred and fifty is right in the middle of three hundred and four hundred so three hundred and forty five is quite close to three hundred and fifty, So I put him just there on the number line.

Now we're going to play Place Value Battle.

This is when you will need your piece of paper, your dice or your online dice, and a pencil.

Now I'm excited because I love this game and I think you're going to really enjoy playing it.

So, on your piece of paper, I'm going to give you ten seconds to draw your place value chart, go.

Pens down, perfect.

So what we're going to do, I'm going to show you what to do first.

So you need to roll your dice, now on my dice, I have got the number one.

Now one is not very high so I'm actually going to put it in my ones column because I think I can roll a bigger number for my hundreds and tens, because the purpose of this game is to roll the biggest or greatest number than your partner.

So I'm going to roll again, actually, it's going to be your turn to roll pause the video, and roll your first number and put it into one of the columns.

Great job, I wonder where you put your number, can you show me? Okay, let's have a look, which number am I going to roll next? Two, oh my goodness, I'm going to put my two in the tens column, because again it's not a very large number and I think I can roll the greatest number for my hundreds column, hopefully.

Your turn to roll, don't forget to pause the video.

Great job, now it's my turn.

Come on, there's no pressure I need to roll a six roll a six, roll a six, roll a six, roll a six roll a six, roll a six.

Can you place some magic on it for me, thank you four, oh I have to put my four into my hundreds column because it's the only blank column left, and my number is four hundred and twenty one.

So now it's your turn to roll your final number, I wonder what it's going to be! Brilliant, is your number greater than mine, or less than mine? Can you put it into a number sentence using our alligator jaws? Remember, alligator wants to eat the greater number, pause this video and do that now.

Super, shall we play again? Thought so, going to quickly rub out my number.

I'm going to let you roll this time, first this time so if you roll your first number, and put it into the columns, remember you need to justify or explain why you're putting it there.

Brilliant, is it my turn? Great, come on six, come on six, come on six.

Four again, now four's tricky because I could roll higher but I could also roll lower so I'm going to put my four into my tens column.

Now it's your turn to roll again.

Super, my turn, Oh I rolled a two again, I'm definitely going to put my two into my ones column, just because I know I can roll greater than that, now it's your turn.

Super job, let's go come on six, come on six.

Oh no, I rolled, a one! So my number this time is one hundred and forty two.

Is yours greater or less than that? Put it into a number sentence using the comparative alligator symbols.

Great job, how fun was that? Maybe we can play that again soon.

Here we have Blackpool Leisure Beach centres visitors, sorry.

So we can see along the top we have the days of the week and below that are numbers of visitors that visited each day, so I can see on Monday there are three hundred and twenty eight visitors, Tuesday was seven hundred and sixty one, Wednesday, one hundred and ninety, Thursday, four hundred and eight one, Friday, nine hundred and eighty one, Saturday, seven hundred and sixty eight, and Sunday, four hundred and ten.

Now my job today is to put those numbers into order.

For example, which day had the least? Which day had the least visitors? Hmm, I'll look at the hundreds columns.

Not Sunday, not Friday, Wednesday, Wednesday had the least visitors because only a hundred and ninety people visited on Wednesday.

Hmm, my next smallest number, hmm it's not Thursday are there any two hundreds? No two hundreds but there's a three hundred, is there any more? No, there's no other three hundreds.

So my next day was Monday.

Okay what's my next next day? Hmm, I've got two four hundreds, is four hundred and eight one greater than or less than four hundred and ten? Hmm, going to look at the tens, one is less than eight, therefore the next number's going to be four hundred and ten, followed by four hundred and eighty one.

Just got three days left.

Hmm, I've got two seven hundreds again okay let's look at their tens columns, oh they both have sixty which means I need to look at their ones columns.

Hmm, Tuesday or Saturday, ah, Tuesday because seven hundred and sixty one is less than seven hundred and sixty eight, so we have Tuesday followed by Saturday, and then the last day is going to be Friday.

So you have helped me, put all of those numbers into order.

So your task today, is to answer these three questions using the chart in front of you, along the top you can see the days of the week, Monday Tuesday Wednesday Thursday Friday Saturday Sunday, and you can see all of these yummy snacks that people could've bought.

So burgers, candy floss, hot dogs, fish and chips yumm yum yum yum yum, and if you go along, you can see on Monday, a hundred and twenty three people bought burgers, on Tuesday, two hundred and sixty seven people bought burgers.

If you go to the next row, you can see it's candy floss row, so on Monday eight hundred and eighty four people bought candy floss, goodness me that's a lot of people, hope they all brushed their teeth, and on Tuesday, only four hundred and fourteen people ate candy floss.

So you are going to be answering the questions below.

Number one, order the burger sales by day from most to least, from most to least.

Two, On which day of the week were the most hot dogs sold? Hmm, so that's one day you need to give me.

And finally, question number three, On which day of the week was the least amount of fish and chips sold? So, you're looking for one day.

So remember to pause this video, before answering the questions.

Good luck, see you in a minute! Great job everybody, let's go through these answers together.

Question one, order the burger sales by day from most sales to the least.

So the greatest number by the least, you should have written, Friday, Sunday, Wednesday, Thursday, Tuesday, Saturday, Monday.

So it's going from the greatest number, from nine hundred and fifty three on Friday, all the way down to the least number on Monday, which was one hundred and twenty three.

On which day of the week were the most hot dogs sold? Monday, eight hundred and forty seven were sold on Monday.

And question number three, on which day of the week was the least amount of fish and chips sold, that was Wednesday, hundred and fifty one portions were sold on Wednesday.

Great job, everybody gives yourselves, one two three, well done me! If you'd like to, please ask your parent or carer to share your work on Instagram, Facebook or Twitter tagging at Oak National and hashtag Learn with Oak.

I've had a really fun lesson with you today and I can't wait to do some more learning with you soon, have a lovely rest of your day, bye!.
