# Lesson video

In progress...

Hi everyone, it's Miss Molnar here, and one of my great friends Harold the hedgehog is here today to do some maths learning with you.

Today, we are going to be consolidating or recapping some of your learning, all about length.

And today you're not going to need anything except your thinking brain ready today for this lesson.

All right, if you're ready, let's get started.

All right, so Harold has been cutting some ribbon.

He's been cutting some ribbon to tie for a birthday present for his friend Nelly's birthday.

He's got to wrap it up.

And he's cut three different sizes of ribbon.

Hmm, I wonder if you could help us describe the lengths of the different coloured ribbon? We've got a blue ribbon, a red ribbon and a green ribbon.

I wonder if we could compare the lengths of each one and maybe we can find out which one is best for Harold to use to wrap his present.

So I'm going to go first and I'm going to compare the blue ribbon and the red ribbon.

So I am going to say, the blue or the blue paper is longer than the red ribbon, 'cause I can see that.

They're right next to each other, and I could see the blue ribbon is much longer.

Do we agree? Thumbs up if we agree.

Well done.

I could also say that the red ribbon is shorter than the blue ribbon.

Okay, I wonder if you could have a go now.

I wonder if you can compare the blue ribbon and the green ribbon using the words longer, shorter or equal to.

Now remember equal to means they're the same, okay? So can you pause the video and compare the blue ribbon and the green ribbon? All right.

What did you use to compare the blue and the green ribbon? What language did you use? Well, we could have said that the green ribbon is shorter than the blue ribbon, or we could have said the blue ribbon is longer than the green ribbon.

Well done.

Fantastic.

Now I wonder, hmm, which ribbon is the longest ribbon? That's right, it's the blue ribbon.

Well done.

Which ribbon is the shortest ribbon? That's right, it's the red ribbon.

So Harold says that he wants a ribbon that's just in between.

He doesn't want to be too short or too long.

Which of those colours do you think would be not too short, but not too long? If you said the green ribbon, well done.

All right, now for your Talk Task, we want you to have a go at this on your own.

We want you to compare the blue, the red and the green ribbon using the language of longer, shorter and equal to.

So pause the video and see how many sentences you can come up with out loud for each one.

All right.

All right, how did it go, everyone? Now, Harold found this one a little bit tricky.

He was trying to compare the blue ribbon and the red ribbon.

How did you compare those two? Were one of them longer than the other? No, that's right.

The blue and the red weren't longer than each other.

So what words did I have to use to compare them? I had to use the words equal to, because there the same length.

So I could say the blue ribbon is equal to the red ribbon, or I could say the red ribbon is equal to the blue ribbon or they are the same length.

Well done.

How could I compare the green ribbon compared to the blue and the red one? That's right, I could say the green ribbon is longer than both the blue and the red ribbon.

Well done, boys and girls.

You're right, so it seems as if Harold has brought a friend today.

Is that right Harold, have brought a friend? Who have you brought? Oh, he's going to go get him.

It's Nelly, the elephant, everyone.

Say hi Nelly to everyone.

Now Nelly, you were doing a little bit of estimating with some measuring, weren't you? That's right.

Now Nelly was trying to estimate how many of Miss Molnar's hands it would take to measure the length of her kitchen table, okay? And Nelly was saying, it would only take two of my hands.

So if I stacked my hands once and then two times that would take up the entire length of the table.

So that's what Nelly was estimating.

But Harold's showing me his thinking face because Harold thinks that that can't possibly be true.

Harold's thinking that's not a good estimate, Nelly.

Surely, Miss Molnar's hand will take much more than two hands to cover the length of the table.

Hmm.

Hmm, what do you think? Do you think Nelly's right? Do you think that only two of Miss Molnar's hands will measure the whole length of the table or you think more? And why do we think that? Hmm.

Well, Harold thinks that Miss Molnar's hands is quite small compared to the table.

So it should take quite a few more hands, hand lengths than just two to cover the table.

Hmm, okay.

Well I think the only way to settle this Nelly and Harold is if we measure the table with Miss Molnar's hands then, shall we see? All right, let's have a go.

All right, so I'm going to take my hand and I'm going to go all the way across my table.

So I'm going to start by this side, so you can see what my hand looks like at the edge.

And I'm going to count, you can count with me how many it's going to take to go across the table.

Are we ready? Here we go.

One, two, three, four, five, six.

So Nelly, were you right, was it? Did it take two of Miss Molnar's hands to cover the table? No, it took much more, didn't it? Because Miss Molnar's hands are quite small compared to the table, but I can still use them as a measuring tool.

Do you remember how many hands it took to cover Miss Molnar's table, the length of it? That's right, it took six of them.

Well done.

Well, what we would like you to do now is we want you to be making some estimates or some good guesses before you're measuring, okay? We can't just say a random number.

We don't want to say 100, or we don't want to say one if we're using our length of our hand.

We want to think of a good guess.

So we'll look at the size of our hand and our foot and we'll think okay, if I'm going to measure something in my home, what would be a good guess before I measure, okay? So that's what you're going to do for your Main Task.

You're either going to use your hand or your foot as a measuring tool, and you're going to choose some things within your home that you would like to measure, but make sure you ask a parent or carer first, what you can measure.

So maybe you're going to measure the length of your table like Miss Molnar did, maybe you going to measure the length of a sofa or a bed using your hand or using your foot, okay? Maybe you've got a rug on the floor that you want to measure the length of, okay? But first remember, you need to make a guess or an estimate, okay? So you could say the carpet or the rug will be 20 hands long, maybe, okay? So you're going to make your guess, then you're going to measure and you can see how close your estimate was.

All right, pause the video and get set to go do some measuring.

How did you measuring go everyone? Were you able to estimate before you measured? What kind of objects did you measure? Well, we're sure that you did some amazing measuring today.

Nelly and I are so impressed.

And we hope that maybe you took some photos of your learning today.

We're sure your teacher would love to see all the learning you've been up to today.

And of course here at Oak we'd love to see the learning you've done as well.

So you could, if you ask a parent of carer, share your learning with us.

Nelly and Harold @Oak on our social media.

All right, well that's all we have time for, I'm afraid today, but we hope that we'll see you again soon.

Bye everyone.
