Lesson video

Hello friends, it's Miss Molnar here and we are going to do some super Maths learning today.

And of course I brought one of my best friends along to help us, Harold the hedgehog.

Say hi everyone to Harold.

Now today we're going to be looking at exploring and comparing different lengths.

All right, now that we're all ready to go let's see what items you're going to need to get ready for this lesson.

Okay.

So for measuring lengths today, you're going to need a few items to help you with this lesson.

So I've made some Play-Doh a little while ago.

So I'm going to use some homemade Play-Doh today to help me.

You might have some Play-Doh at home already that you could use or you could ask a parent or carer to help you find a Play-Doh recipe and make some Play-Doh.

Or if you don't have any Play-Doh, you could probably do the same thing by using some string or some ribbon or anything long that you can kind of cut.

So ask your parent or carer what you can do about that.

And then what you're going to need is some kind of toys or objects.

So I'm going to use a few different compare bears today but you might want to use some of your favourite action figures or some of your favourite teddies.

Again, make sure you ask a parent or carer first.

All right.

So go grab those items and then we'll come back together to get started.

All right.

I think we need to get our brains warmed up to start this lesson.

We're going to find out what one less than a number is.

So if you look up my number track if we want to find one less than the number we're going to start on the number and then we need to do a jump back to find what is one less.

All right.

So I've got the number three on the screen.

I want to know what is one less so I can try and imagine what would it look like if I took one of the blocks away from the number three.

What would the new number be? Use the number track below to help you.

That's right.

It would be number two.

Two is one less or one block less than number three.

Two is one less than three.

Let's try another one.

All right, we've got number five.

Now.

Let's try and imagine.

What would it look like if we took one of the blocks away from number five.

What number would we be left with? That's right.

We would be left with the number four.

Excellent job, everyone.

One less than five is four.

All right.

Now we're going to try this one here.

What is going to be one less than the number one? What would happen if we took the number one block away? Hmm.

That's right.

We would be left with zero or nothing if we took one away.

So one less then one is zero.

Fantastic job, everyone.

All right.

So we're back at Polly's Cafe here.

And we're going to look at describing some of the items in the cafe using some new language today.

So in order to compare length, we might say that something is longer than another object.

I say you say longer.

Well done.

If we want to compare another object and describe it as smaller than the other object in terms of its length, we would describe it as shorter.

I say you say shorter.

Well done.

All right.

Let's see what we can find in the kitchen here to compare in terms of length using the words longer and shorter.

All right.

Take a look at the spoon, the large spoon hanging on the wall.

Can you find it? Well done we've spotted it as well.

It's the spoon hanging on the wall.

Now, can you spot one of the spoons on the table? Great.

So we've got a spoon hanging on the wall and we've got a spoon on the table which one is the longer spoon and why do you think that? Well done.

We could say that this spoon hanging on the wall is longer than the spoons on the table because it's much bigger, isn't it? If we compared them side by side we can clearly see that the spoon on the wall is longer.

Now let's take a look at the ball of yarn on the floor, in the picture.

Can you spot it? Point to it if you found it.

Well done.

there's the ball of yarn.

I wonder what do you think if we unravelled this ball of yard all the way so its stretched it out.

So it's just a long piece of yarn.

Do you think that it would be longer than or shorter than one of the cat's tails? And why do you think this? Hmm, You might want to pause the video for a minute to have a think.

Now this is a bit tricky because at the moment I can see the string on the ball of yarn looks shorter than the cat's tail.

But Molnar said, imagine we unravelled the whole ball of yarn and pulled it straight to be one long piece of yarn.

Then we would know that it must be longer than the cat's tail.

The cat's tail is shorter than the ball of yarn.

All right.

So there's going to be four of Harold's friends who are going to go to Polly's kitchen.

So I've got one, two, three, four bears and they're all different sizes.

Can you see which bear is the smallest size bear.

If you pointed to the purple one, you're right.

That is the smallest bear.

Can you see which bear is the largest bear.

If I put them this way to compare these two they're a little bit tricky to see which one is larger.

If you said the red one, well done the red one is slightly bigger or slightly larger than the yellow bear.

So we know which one our smallest bear is.

And we know which one our largest bear is.

Now, Polly wants to make them some baguette to have in her kitchen.

A baguette is like a really long piece of bread but Polly wants to make sure we get each bear a size of baguette that's relative or similar to the size of the bear.

So we want to give the smallest bear the smallest sized baguette and we want to give the largest bear, the largest size baguette.

So what I'm going to do is I'm going to get a little bit of my Play-Doh and I'm going to roll it with my hands to try and make a baguette size.

All right.

So I'm going to give my littlest or my smallest, shortest baguette to my smallest bear.

All right.

Now I need to make another baguette for my next largest bear.

Which one is going to be the next size up.

If you pointed to the blue one, well done.

The blue one is going to be my next largest bear.

So I'm going to get a little bit of a Play-Doh this time and give it to my next biggest bear.

What do you think? Have I made this baguette the right size for this bear? Why or why not? If you said no.

Well done.

Remember we said the smallest bear needs to have the smallest sized baguette and the next size up of a bear, needs it to be a little bit bigger.

So if I compare my baguettes side by side I can see that this one is too short.

It needs to be longer than my smallest size.

So I'm going to give this back to the little bear here, the purple one.

And I'm going to make my baguette.

I'm going to make sure it's longer than the purple bear's baguette.

All right, let's see.

I'm going to compare it again.

I'm going to put the next to each other.

Can I start comparing them like this? No, I have to make sure that I line both of the pieces of baguette at same starting point and make sure it's a little bit longer.

I think I can make it a little bit longer.

All right, there we go.

Thumbs up.

If I've made the second baguette longer.

Well done.

All right.

So purple bear has it's baguette.

The blue bear has its baguette.

which is going to be my next longest baguette for the yellow bear or the red bear.

That's right.

I need to make the next one yellow bear.

All right.

Let's see.

What do we think.

Have I made it longer? I have.

Way to go.

I think I can make it a little bit longer though.

Tiny bit more.

But I'm going to compare them to make sure it's longer than both of the other bears baguettes and I'm going to give it to my yellow bear.

And then finally, we need to make the longest baguette for the red Teddy bear.

All right.

I've rolled it out.

Let's compare now and make sure.

Lining them up to make sure that it is longer than the last one.

Thumbs up or thumbs down.

Have I made this baguette longer? I sure have.

Well done.

So the largest Teddy bear is going to have the longest baguette.

Okay.

So for your Talk Task, all we want you to do, is to get some Play-Doh whether it's Play-Doh that you already have at home or you've made.

Or if you don't have Play-Doh, you could grab some string or some yarn or some ribbon as well.

We want you to make some different size baguettes.

Okay? So nothing with anything with any teddies yet.

Just use your Play-Doh or string and make some different sized baguettes.

Then what you're going to do is use the sentence STEM to compare and describe the lengths of some of them.

So you'll pick two and you can say this baguette is longer than this other baguette or you can say this baguette is shorter than this one.

This baguette is the longest one or this bag is the shortest one.

So have a go at using the Play-Doh or a string and make some different size baguettes and compare them using the sentences.

All right, our teddies have arrived at the cafe and they are ready for what their baguette.

So you need to help me match up the right size baguette with the right size Teddy.

Alright, let's look for the smallest size baguette.

Can you point to it on the screen? Well done.

Here's my smallest baguette.

Now can you point to the smallest size teddy bear that I need to give it to? Well done.

If you pointed to the purple teddy bear, you are right.

All right.

Point to the next baguette that is the next longest.

This is a bit tricky.

I'm not sure if it's this one or this one.

So I'm going to take this one and put it side by side to compare.

Which one is the next longest? Way to go.

This one is the next longest size.

And which teddy bear do I need to match it up with? The blue one.

Way to go.

Now I've got two baguettes left.

I need the next longest one but not the biggest one in general.

The next size up.

Way to go.

If you pointed to this one.

Now which is our next largest teddy bear? the yellow one.

Fantastic.

And that leaves my longest baguette for my biggest Teddy bear.

All right.

Now let's put them in order from smallest to the largest.

So what colour teddy bear comes first? Great.

Purple comes first at the table.

What colour is next? Blue.

Fantastic.

What colour is next? Yellow.

And then finally, we've got red with our longest baguette.

All right, now you're going to have a go at the main task.

You need to take your teddies or your toys and you need to serve them your baguettes according to size.

So your smallest size toy, needs to have the smallest or short test baguette and your largest toy needs to have the longest baguette.

Okay.

So once you've done that, once all of your toys have a baguette according to size, then you need to put them in order from the longest baguette to the shortest.

You're going to line up all of your toys.

All right.

Pause the video and have a go at that now.

All right.

How did it go ordering the different sized baguettes you made with all of your toys? Did you manage to give your largest toy? Those longest baguettes? That's so great.

Well, that is all we have time for today I'm afraid but we would absolutely love it if you take any pictures of your learning from today and you share it with your teacher.

They would be so thrilled to see all the great learning you've been up to.

And if you like, Harold and I would really really like to see those photos as well.

So if you ask a parent or carer, they could share your photos with us on social media.

All right.

Thanks again, everyone.

And we'll see you next time.
