Lesson video

Hello, welcome to the lesson.

My name is Miss Jones and we're going to be doing the lesson together today.

Today, we're going to be looking at measuring some objects.

Are you excited to get going? Okay, let's begin.

Today we will be beginning to understand units of measure.

We're going to be looking at a standard unit of measure today called a metre.

First of all, we'll talk about what one metre is and how long that is and what it looks like, then we're going to be looking for some objects smaller than one metre and some objects larger than one metre.

You've then got your independent task, and finally, your end of lesson quiz.

For this lesson, you'll need a pencil and piece of paper to write with or something else to write with and write on.

If you have one, you'll need a measuring tape.

Don't worry if you don't have one, I will show you how I use mine to measure one metre and you can do some estimating.

Pause the video now and go and get everything you need.

If you've got everything you need, let's get started.

Here, we have our big picture, which shows Pinocchio and his owner, his creator, Geppetto.

We need to help Pinocchio and his dad, Mr. Geppetto, measure the floor for some carpet.

What could we use to measure the floor? Do you think it's a good idea to use some paperclips or some counters to measure the floor? What do you think? We could use something like a paperclip to measure the floor, but it would take us a very, very long time to line up paperclips and we would need a lot of paperclips to measure his whole floor, wouldn't we? Instead we might need to use a ruler.

Now, some rulers are quite small.

This long ruler here is a metre ruler or a metre stick.

We could use that to help us measure the floor.

Let's have a look at a metre stick a little bit more closely.

Here is a picture of a metre stick.

This is a picture of a normal school ruler.

The school ruler is 30 centimetres long.

Now, a metre stick is a metre long and a metre is the same as 100 centimetres.

Little challenge, what's the difference between 100 and 30? Now, don't worry if you're not sure, I'll tell you.

It's 70 centimetres.

A metre stick is 70 centimetres longer than a ruler.

Let's have a look at what one metre looks like using my tape measure.

Let's have a look at what one metre looks like using my tape measure.

Now, I need to find the number 100 because there are 100 centimetres in a metre.

The number 100 is here.

This is what one metre looks like from my finger here to my finger here.

You can see how wide one metre is.

If I use my tape measure to measure my table, I can see that my table is shorter than one metre.

I could use it to measure my chair.

Here is one metre.

I can see my chair is about one metre tall.

Can you think of any items that are even taller or longer than one metre? I wonder if we could look around in our environment to find objects and items which are taller or longer than one metre.

Have a think and have a quick look around.

Can you see anything that's longer or taller than one metre? Here we have an example, the fridge.

I think the fridge is taller than one metre.

How do I know? Well, I know that one metre is the same as 100 centimetres.

I know that the fridge is taller than 100 centimetres and it's therefore taller than one metre.

I could check using my tape measure and see how tall the fridge is.

What can you find in your house that's taller than one metre? Hm, what about this radiator? Do you have a radiator in your house? I wonder how we could check how long the radiator is.

I think the radiator is shorter than one metre.

I could check using my tape measure.

If the radiator is shorter than 100 centimetres, it must be shorter than one metre.

Have a look around and see if you can find an item that is shorter than one metre.

If you have a radiator in your house, you might want to test this out and see if it is shorter than a metre or longer than a metre.

You can use a tape measure if you have one to double-check.

If not, you can just estimate.

Pause the video now and go and see if you can find something.

How did you get on? Did you find an object that was taller than one metre? And did you find something that was shorter than one metre? Did you have any radiators in your house that you could measure? It's time for your main task.

For this task, there's going to be two parts, so I want you to go off and do part one, and then come back and then go off and do part two.

Your first task, I'm going to need you to be a metre detective.

I want you to go around your house and see how many items you can find that is longer or taller than one metre.

Now, remember, if you don't have a metre stick or a tape measure, you're going to need to make an estimate or a prediction.

You can use this sentence then.

I predict that the bunk bed is taller than one metre.

What else is taller than one metre? What's taller than one metre in your house? If you can't remember what one metre looks like, you can always rewind the video back to me with my tape measure to double-check what one metre looks like.

If you do have your own tape measure or metre stick, you could use that to help you check.

Okay, off you go.

Pause the video now and find objects that are taller or longer than one metre.

How did you get on? Did you find some objects longer than one metre? Guess what we're going to do in part two? This time I want you to have a go finding some objects that are shorter than one metre.

Now I know there's going to be a lot of those, so hopefully you'll have plenty of objects as a detective to go and find.

And remember, if you don't have a metre stick or a tape measure, you need to predict.

I predict that the footstool is shorter than one metre.

Try and use the sentence then, and you might want to have a go this time at explaining how you know.

Remember, there are 100 centimetres in a metre, so if it's shorter than a metre, it needs to be less than 100 centimetres.

Okay, time to go off and find some objects shorter than one metre.

Pause the video and then come back to the video when you're done.

How did you get on with your main task? What objects did you find that were longer than one metre? What objects did you find that were smaller than one metre? Did you have a go at explaining how you know? Remember, there are 100 centimetres in our metre, so our smaller objects were less than 100 centimetres.

Our larger objects were more than 100 centimetres.

Did you enjoy the lesson today? I hope you did.

If you want to, you can share what you've done by asking your parent or carer if you can share your work with Oak National.

Before you go, you'll need to complete our multiple choice quiz.

Thanks, everyone, hope you have a lovely day.
