Lesson video

Hi everybody.

Today, we have a really fun lesson ahead of us.

We're going to be applying our place value knowledge to problem solving.

So let's get started, put on your hat and tighten your ties, and tell the computer, now I'm a mathematician.

But before we get started with the lesson, make sure that you have a nice, quiet place to work.

Today's lesson, you're going to be using your brain.

Lets get started.

So here is today's lesson agenda.

We're going to do our star words, Then we're going to do some practising together problem solving before it's your turn.

So let's get started as always, please make sure you have these resources in front of you.

A pencil, a paper and a ruler.

If you need to go get anything, please pause the video now.

Great.

Let's get started.

Here are our star words.

Can't hear you, star words.

Greatest.

Smallest.

Value Multiple.

Even.

Odd.

Closest.

Brilliant, remember we need to use them all the time, So if you spot me not using them, then make sure you give me a whispered reminder through the computer.

Here is our problem solving.

We have got the digits zero, one, two, three, four, five, six, seven, eight, and nine.

And we need to make two digit numbers, largest even number the largest odd number, the smallest odd number, largest multiple of 5 and the number closest to 50.

So we're going to walk through this together because you can only use each digit card once.

So I have got mine written here.

If you quickly write yours on your piece of paper.

I'm going to give you 10 seconds.

Super lets start with, I'm actually going to suggest we start with the number closest to 50.

So number closest to 50, I'm going to go for 51.

So I've written 51 on that.

I then need to cross out five and one, pause the video.

And you do the number closest to 50.

Super let's have a look at the next one, largest multiple of five.

Well, I've used, I've used five already, So my number has to end in zero.

As I know that multiples of five end in zero or five.

And I'm crossing out zero, and the largest multiple, I'm going to keep eight and nine so I can see, I might need them.

I'm going to do 70, so I've written 70, and now I need to cross out seven.

Now it's still a turn, pause the video.

Great, smallest odd number.

Ooh, I've already used one.

What's the next odd number after one? Oh three.

So I'm going to write three.

Ooh, but has to be two digit number.

Hmm, Hmm.

It's going to have to be 23.

Can you see, I'm really thinking about this guys.

So now it's your time to find the smallest odd number, pause the video.

Super, so now we are left with the largest even number and the largest odd number.

Now I'm going to to write out the numbers that I have left, which is four, six, eight and nine.

And I know my odd number has to end in nine so the largest odd number I'm going to have is 89, which means my largest even number is going to be 64.

Pause the video and you fill in those last two together.

Great job, now I'd love to see what you came up with.

That was really fun doing that problem solving together, wasn't it? Super so for your task today, you have got these digits.

Now I have actually given you some extra digit cards because you are going to be finding three digit numbers, not just two, three, so you need to make the largest odd number, the largest even number, the largest multiple of ten, the largest multiple of five and the closest number to 500.

Now I've done this as well.

And we're going to pause the video.

You're going to have your go and we'll come back together and I'll show you the answers that I got.

Good luck, can't wait to see what you get, pause the video.

Great job guys, how much fun was that? Now these are the answers that I came up with.

So the largest odd number I got was 999 the largest even was seven, seven, six, 776 the largest multiple of ten 630.

The largest multiple of five is 415.

And the number of closest to 500, was 512.

Now I'd love to see what you came up with because I wonder if we got similar answers.

But I hope you enjoyed that problem solving lesson today.
