Lesson video

Hello, welcome to today's lesson.

It's me Miss Jones.

Hope you're feeling excited to do some maths today, are you feeling ready? Shall we start then, let's go.

In today's lesson, we're going to be measuring using non-standard units.

You'll need some things to help you.

Our main tool today is actually going to be our hands.

I'm sure you've all got those already, but you'll also need a range of objects to measure.

Ask your parents or carer what you can use, but try and get some objects of different sizes, you might use one of your teddy bears, some of your toys or adult or some household objects, such as jars or cups.

Pause the video now to go and get what you need.

Our agenda today, we're going to be introducing non-standard units.

We're going to be comparing lengths using our non-standard units.

You've got your independence task, and then we've got our quiz.

They're going to be times today where you may need to pause the video and go and do your activity in your own home.

I'll let you know when to do that.

First of all, let's warm up.

Have a look at your hand, can you find three objects that are longer than your hand? Can you find three objects which are shorter than your hand? If you haven't got the objects with you, you might want to ask your parents or carer to go and get them.

Pause the video now and go and have a look.

Did you find your objects? Which of your objects are longer than your hand? Which of your objects are shorter than your hand? Can you point to them? Here is our big picture, in our picture, we have the story of Pinocchio, the wooden boy, and this is his creator, Geppetto.

This is Geppetto's workshop.

He makes lots of things in his workshop and he needs to be able to measure them to help him.

What can you see in the picture? Can you spot a ballerina? Can you spot some tools? Point to them.

Can you see the rugs? Hmm.

What's longer? The books? Or the chair? Hmm.

Look at these rulers.

Which one is the shortest? Can you point to it? We're going to be using this big picture today to help us, Mr.Geppetto needs to the sleeves for Pinocchio's jumper, but he has lost his tape measure and he isn't sure whether he has enough material to make it.

If we haven't got a tape measure or ruler, how could we check? Have a little think.

Okay, well we could use some non-standard units, we could use an object or part of our body in order to measure something.

For this chair.

I'm going to measure using hands.

Now I've got these hands, but if you wanted to, you could measure a chair in your own house using your own hands.

We're going to be using these key sentences, the chair is about hmm hands tall.

Can you say that? The chair is about hmm hands tall or we could say the chair is close to hmm hands tall.

We say about or close to because it's not an exact measurement, it's an approximation.

Hmm, how many hands tall do you think this chair is? Have an estimate? Why do you think that? Let's have a look? Shall we? My chair was about six hands tall.

Now we say tall here instead of long, because we're measuring it from the bottom to the top or from the top to the bottom, and it's standing upright.

If we're measuring something flat, we would say long, can you say this after me? My turn, your turn.

The chair is about six hands tall, your turn.

Hmm, how can we measure this rug? This rug is laying flat, so we don't say tool this time, we talk about how long the rug is.

Instead of saying about another word we can use is roughly, which means the same as about the rug is roughly hmm feet long.

Can you say that? Your turn.

Hmm, how many feet long do you think this rug will be? Let's have a look, the rug is roughly five feet long.

Your turn.

Now it's time for your talk task.

In your top tasks today, I'm going to ask you to go off and measure some objects using your hands and feet.

Now, before you measure each object, I'd like you to do an estimate.

An estimate is an educated guess.

Think about how long your hand is and use that information to guess how long you think your object is.

Once you've done your estimate, you can check by measuring.

These two have had a go at measuring a table, she says that I estimate the table will be seven feet long.

But when she checked, she said, the table is about eight feet long.

Her estimate was pretty close.

This person's used their hands, I estimate the table will be 12 hands long.

The table is nearly 15 hands long.

So the table was a little bit longer than she thought.

Now for your talk task, you could measure a table or a chair.

It doesn't matter what objects you measure, you might want to measure some of the objects that we gathered earlier, but make sure you're using these sentence stems. I estimate hmm the object is narrowly or roughly you can use your hands or your feet, or you can try using both and see what the difference is.

Okay, it's time to pause the video and go off and do your talk task.

Hopefully you've had a chance to complete your talk task.

How did you get on? Hmm, let's have a look at this next question, which bookcase is longer? This one is five feet, this one is seven hands, hmm now it's very hard to compare because we're using different units of measure.

This one's been measured with feet and this one's been measured with hands, hands and feet are not the same size.

So we cannot compare these because they using different objects to measure.

If we measure them using the same thing, both using feet, then we can compare.

This bookcase is five feet long, this bookcase is shorter than four feet, this bookcase is the longest.

Now that we're using feet to measure both, then we can compare.

It's time for your independent task.

I'd like you to measure the length of object using your hands.

Now you're going to need to try and find about five or six different objects to measure.

Make sure you use your sentence stems that we talked about.

The hmm, is about, hmm, hands long.

That's shorter than the hmm because it's roughly hmm hands long.

I'd like you to compare your objects, make sure you're using the same units of measure though.

If you've got somebody helping you and they have larger or smaller hands, you might not be able to compare.

Make sure you use the same unit.

So just your hands or just their hands before you make a comparison, when you're done, can you tell me, which was the longest object? and which was the shortest object? You've got a table like this on your activity sheets, fill in.

Pause the video now and go into your task.

When you finished press play and we'll finish off the lesson together.

Hopefully you've finished your task by now, which object that you found was the longest? Which one was the shortest? What unit of measure did you use? Did you use your hands? Or did you use your feet? If you would like to ask your parents or carer to share your work from today.

Now that you finished go off and try our multiple choice quiz to see what you've learnt.

Thanks everyone.
