Lesson video

- Hello everybody.

It's Miss Charlton here and my talk partner, Hedwig, my very sleepy owl.

Hopefully you've got your talk partner ready with you as well.

Do you think Hedwig's gonna be able to stay awake this lesson? We'll just have to see, won't we? Now let's get started and see what we're going to be learning today.

Today is all about 2-D shapes and we're going to learn to identify them.

We'll go through the identification and the names of the shapes.

Then we'll identify the key properties, the key features of the 2-D shapes.

Then you'll do your independent task and an end of lesson quiz.

Today you'll need a pencil and some paper.

And if you want to cut out the pictures of the shapes then you'll need some scissors.

And if you want to draw the shape yourself you might need a ruler to be able to do that.

Let's go through the star words.

Get your hands ready.

Hands up, star words.

Side.

Vertices.

Curved.

Straight.

Now vertices is a really key one.

We're going to check how many corners there are on lots of different shapes.

- [Narrator] We're off to London to find some 2-D shapes.

We're going to hunt for squares, rectangles, triangles and circles.

Are you ready? Let's go.

Oh, a London bus.

What shapes can you see? Look carefully.

Rectangle shaped windows.

Rectangle shaped steps.

Circle shaped wheels.

Let's keep going.

Look, it's Big Ben.

What shapes can you see? Look carefully.

Lots of shapes here.

I can see a rectangle, a square, a triangle, and a circle.

What will we see next? Wow, it's the London Eye.

What shapes can you see? Look carefully.

It's a big circle with a triangle stand.

Look at all the small triangles and circles around it too.

So many shapes.

Where to next? Look, it's Tower Bridge.

What shapes can you see? Look carefully.

Can you see the triangles and the rectangle? 2-D shapes are everywhere.

Maybe you can find some where you live.

- Hopefully you enjoyed that video.

Now let's have a look.

We've got the big picture in front of us with lots and lots of different treats on it.

All those treats are making me hungry.

Are they making anyone else hungry as well? Now, I notice that all of those treats are in different shapes.

Can you see the biscuit in the roof that's in the shape of a triangle? I can see two of them there on top of each other.

Can you see the biscuit in the shape of the square on the roof? Can you spot that? Can you point to it? Show your talk partner.

Can you see, oh, can you see the lollipop in the shape of a circle? Can you see that Hedwig? I can see that.

I can also see a lollipop in the shape of a rectangle.

There are so many different shapes that I can see on that picture.

I wonder which one you'd want to eat.

Now, we are going to use all of that knowledge of shapes to try and recognise other shapes.

So let's have a look here.

This shape is a rectangle.

Now what does a shape need to have to be a rectangle? Let's look again at our big picture.

Let's look at that lollipop.

Hmm, I can see that it's got one, two, three, four sides on that lollipop.

And I can see its corners, its vertices.

How many vertices has it got? Let's count together.

One, two, three, four, four vertices.

That pink and yellow lollipop has got four vertices.

Look, that looks very similar to the shapes here.

They are both rectangles.

They've got four sides, straight sides, and they've got four vertices, four corners.

Now, what do you notice about the sides? Are they all the same length? No, they're not.

Two of them are longer than the other two.

So we say, two sides longer than the other two.

Can you say that? Two sides longer than the other two.

That's what rectangles have.

They've got four vertices, four sides, two sides longer than the other two.

Now all of these shapes that you can see in front of you are rectangles, but what looks different about them? Hmm, I can see they're all different colours.

There's a green one, a red one and a blue one.

But I know that they're all rectangles because they meet the properties that we've just discussed.

But what's different? Ah, look, they're all at different angles.

I can see the green one is straight in front of me but the red one, it's still a rectangle, but you might just want to tilt your head.

Can everybody tilt their heads to the side? Can you see that that's still a rectangle? It's just on its side, isn't it? The same with the blue one.

It's still a rectangle, but it's on its side.

They're all the same shapes, but they're just tilted at different angles, which makes it a bit tricky to spot them.

Now, let's explore the square.

What does a shape need to have to be a square? Well, we just went through the properties of a rectangle.

Look, we've got four straight sides, four vertices, two sides longer than the other two.

Let's use some of those to compare.

Hmm, does the square have four straight sides? Yes it does, doesn't it? One, two, three, four.

Can you count those? One, two, three, four.

Hmm, so it's got four straight sides.

What about the vertices? Let's count those.

One, two, three, four.

Four vertices, just like with the rectangle.

Four straight sides.

Four vertices.

But what's different? Look, does it have two sides longer than the other two? No it doesn't, does it? Those shapes, the squares, all have sides of equal length.

They are equal.

They are all the same length.

Now a square is a very special type of rectangle.

A square is a type of rectangle that has four sides of equal length.

Now let's have a look at this shape.

This shape does not look like the square and the rectangle because it doesn't have four sides and it doesn't have four vertices.

How many vertices does it have? Let's count.

One, two, three.

All of those shapes have three vertices.

One, two, three.

It has three straight sides.

Let's count them together.

One, two, three.

Oops, went on to the wrong slide there.

So we've got three straight sides and three vertices.

And that's what different to the other shapes, which had four straight sides and four vertices.

Now, we are going to use all of those to do our independent task.

Your job is to make a picture using different shapes.

Can you see in front of you? I've made a picture of a person.

I've used a triangle for its hat.

Look, one, two, three.

It's a yellow triangle.

I know it's a triangle because it's got three straight sides and three vertices.

What have I used, what shape have I used for its body? Can you have a look? Hmm, how many sides has it got? Let count them together.

One, two, three, three sides.

How many vertices? One, two, three vertices.

Three sides and three vertices so the shape must be a triangle, just like its hat.

So those are both triangles but they're different sizes.

What shape have I used for its arms? Hmm, lets count the sides.

One, two, three, four.

It's got four sides and how many vertices has it got? One, two, three, four, four vertices.

So it could be a square or it could be a rectangle.

Hmm, which of those is it? It must be a rectangle because it's got two sides longer than the other two.

So I've used rectangles for arms. Now you have got all of these shapes that you could use to try and build your own picture.

You can use the shapes provided or you can draw your own shapes as well.

Now, if you're cutting theses shapes out, please be very, very, very careful if you're using scissors.

Maybe there's somebody around that can help you cut carefully and you can use any of those shapes that you want to to create a picture.

You might like to make a picture of a person or a house or maybe even a picture of an animal.

Pause the video now and have a really great time exploring all of those shapes and trying to make a wonderful picture.

Now just before you go and complete the quiz, we need to wake up that sleepy owl.

Are you ready? Everyone say wakey, wakey, Hedwig.

Wakey, wakey, wakey, wakey.

There she is.

Oh, she's sleepy.

Now Hedwig, you missed all that lesson again so we need to tell you what we've learned.

Hmm, what skills and knowledge did we learn today? Well, we needed to identify different 2-D shapes and in order to do that we used the mathematical language of the properties.

So we use words such as vertices and sides to describe the properties of the shapes that we were using.

Then we used those shapes using our mathematical language to create pictures.

Do you think she understood? Lets see.

I think she did understand.

Maybe you could have, maybe you could use your shapes to create a house for Hedwig to live in.

A little owl box.

I hope you've had a really great time exploring those shapes today.

See you again very soon, bye-bye.
