Lesson video

Hello, my name's Mrs. Kaylee, and I'm going to be your teacher for today's lesson.

We're going to be learning about comparing items or objects using length and height.

So let's have a look at the outcome of today's lesson.

So here's today's outcome.

I can compare objects according to their length and height.

Here are our keywords for today's lesson.

Can you say them after me? Taller than, longer than, shorter than, further, less far.

Well done, we'll be using these words to compare objects looking at their length and height.

Here's the lesson outline for today.

So first of all, we will compare different heights and then we will compare different lengths.

So let's start on the first part of the lesson.

Here's some children that are going to help us for today's lesson.

We've got Alex, and we've got Sam.

What do you notice about Alex and Sam? That's right.

We can compare their height.

We can measure height to find out how tall things are.

We can compare heights using the words taller or shorter.

Who is taller and who is shorter? Alex or Sam? That's right.

Alex is taller than Sam, and Sam is shorter than Alex.

We can see that from the picture, can't we? What do you notice now? Can you see that Sam is standing on a box? Is Sam taller than Alex now? No.

Sam may appear taller, but we are comparing Alex with Sam, not Sam and the box.

So Alex is still taller than Sam.

We can compare heights more easily when one end of each person or object is lined up.

Can you see they're standing on the floor now? We can use a level floor to stand on.

Which is taller and which is shorter? The car or the tree? Can use the stem sentences to help you.

That's it.

The tree is taller than the car.

The car is shorter than the tree.

Let's check your understanding.

Which is taller? The apple or the pineapple? Can use the stem sentence to help you.

That's right.

The pineapple is taller than the apple.

Which is shorter? Use the stem sentence to help you.

Yes, the apple is shorter than the pineapple.

Well done.

Who is correct here? Sam said, "The box is taller than the door." Alex said, "The box is shorter than the door." Who is correct? Who do you agree with? That's right.

Alex.

The box is shorter than the door.

Who is correct this time? Sam said, "The apple is taller than the pineapple." Alex said, "The apple is shorter than the pineapple." Who is correct? Who do you agree with this time? That's right.

It was Alex.

The apple is shorter than the pineapple.

Even though the apple's on a box, it's still shorter than the pineapple.

Now there's a task for you to have a go at.

Can you try to find five objects that are taller than you? And then can you find five objects that are shorter than you? And you can draw them or write about them and I want you to think how can you check.

So pause the video and have a go at this task.

Here's your second task.

Can you use the words taller and shorter to compare the objects? We've got a tree, a car, and a house.

Can use the stem sentences to help you.

So pause the video and have a go.

Did you get on? Did you manage to find five objects that are taller than you? So you might have found something like this: a door, adult, a bookcase, a tree, a lamppost.

And did you find five objects that are shorter than you? You might have found things like this: a chair, book, pencil, rubber, glue stick.

There are lots of things that you might have found.

So what did you find, and how did you check? Did you line them up? Did you stand on the floor next to it? Did you find the same as your friends? Why or why not? If you are the same sort of height as your friend, you might have found the same objects.

If you are different height, you might have found different objects.

How did you get on on the second task? Did you use the words taller and shorter to compare the objects? So you might have said, the house is taller than the car and the car is shorter than the house.

You might have said, the tree is taller than the car and the car is shorter than the tree.

You might have said the house is taller than the tree and the tree is shorter than the house.

Did you notice how the two words can swap round when we change from taller to shorter? Well done.

Let's move on to the second part of our lesson.

We're going to compare different lengths.

What do you notice here? We can measure length to find out how long things are.

We can compare lengths using the words longer or shorter.

What do you notice? Can use the stem sentences to help you.

Which one is longer and which one is shorter? The pen or the pencil? That's right.

The pen is longer than the pencil.

And the pencil is shorter than the pen.

What do you notice now.

This one's a bit harder, isn't it? They're not lined up.

Which one is longer? Which one is shorter? How can we check? It's easier to compare when the objects are lined up.

So let's line them up.

That's better, isn't it? What do you notice now? Yes, they're the same, aren't they? Neither the pen nor the pencil is longer or shorter than the other.

So the pen is the same length as the pencil.

The length of the pen is equal to the length of the pencil.

What do you notice with these pieces of ribbon? Which ribbon is longer and which ribbon is shorter? How can we check? It's quite difficult, isn't it? Because they're quite wobbly and they're not lined up.

Let's line them up.

That's better, isn't it? Can you see now which ribbon is longer and which ribbon is shorter? Remember, when one end of each object is lined up, we can more easily compare their lengths.

We've also straightened them to compare them.

That makes it even easier to see.

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

Which ribbon is shorter? Yes, the blue ribbon.

What do you notice here with the green ribbon and the yellow ribbon? It's harder to compare, isn't it? Which ribbon is longer and which ribbon is shorter? How could we check? That's it.

We can line them up to make it easier to compare.

We've lined them up the ribbons, but remember to straighten them.

There we go.

We've straightened them now.

That makes it much easier to compare.

Which ribbon is longer? That's it.

The green ribbon.

And which ribbon is shorter? The yellow ribbon.

Even though the yellow ribbon is wider, it is still shorter.

Which is longer? The car or the bus? Can use the stem sentence to compare them.

Which one is shorter? The car or the bus? Can use this stem sentence to help you.

That's right.

The bus is longer than the car.

The car is shorter than the bus.

Well done.

How could we check? That's right, we can line them up.

It is easier to compare lengths when they are lined up.

Which car travelled the furthest from start to finish? I can see that both the cars have started at the same place.

There we go.

The red car has moved, and the blue car has moved.

Which car travelled the furthest? We can use the stem sentences to help us.

That's it.

The blue car travelled further than the red car.

The red car travelled less far than the blue car.

Which vehicle travelled further here? The car or the bike? Which vehicle travelled less far? Let's use these stem sentences to help us.

The something travelled further than the something and the something travelled less far than the something.

That's right.

The car travelled further than the bike, and the bike travelled less far than the car.

Well done.

Here's a task for you to have a go at.

Can you find five objects that are longer than your pencil? And then can you find five objects that are shorter than your pencil? And you can write or draw them.

And I want you to think about how can you check, so pause the video and have a go.

This is your second task.

Can you roll two cars? If you can't find cars, you could find balls or marbles.

And I want you to see which one travelled the furthest and which one travelled less far.

And think about how can you check, so pause the video and have a go at this.

To get on with your task, did you find five objects that are longer than your pencil? You might have found things like this: a book, table, chair, ruler, shoe, arm.

Did you find five objects that are shorter than your pencil? You might have found things like this: rubber, sharpener, cube, finger, counter.

What did you find? Did you find the same as your friends? Why or why not? So you might have had a different sort of pencil to your friend.

Some pencils are longer than others, aren't they? So it depends which sort of pencil you had.

So you might have found the same objects as your friends or different objects.

How did you get on with the cars or the balls? Which one travelled the furthest and which one travelled less far? Sam said, "My green car travelled the furthest." What did you find and how did you check? Did you start them off at the same place? Did you find the same as your friends? Why or why not? You might have had different cars or balls to your friends, so you might have had a different result.

Well done.

We've come to the end of our lesson now.

Let's see what we've learned.

So today, we've been comparing items using length and height.

We found that objects can be compared according to their length and height.

The words taller, longer, shorter, far, further and less far can be used to compare the length and height of objects.

It is easier to compare objects when one end of each object is lined up.

Well done, everyone.

See you next time.
