Lesson video

Hello, everybody.

My name is Mrs. Johnson.

I am really excited to be here today to help you with some of your maths learning.

I hope you are ready to do some hard work and to have lots of fun.

Let's have a look at what we're going to be learning today.

Today's lesson is called Composing Pattern Block Images.

It comes from the unit Recognise, Compose, Decompose, and Manipulate 2D and 3D Shapes.

By the end of this lesson, you will be able to make different pictures and patterns using pattern blocks.

We're going to be learning all about how you can use different shaped blocks to create different pictures and different patterns.

Some of what we learn today might be new learning, but that's okay because we're going to work through it together and have lots of fun.

We are going to be using four keywords in our lesson today.

I'm going to say them first and then we're going to go through and practise saying them together.

Our keywords today are: pattern blocks, picture, rotate, and pattern.

This time I'm going to say them and then I would like you to say them after me.

Ready? Pattern blocks.

Picture.

Rotate.

Pattern.

Good job.

I wonder which of those words you've heard before and which of those words might be new.

Listen carefully through this lesson today and see if you can spot all of those keywords.

There are going to be two main parts to this lesson.

The first one, we are going to be learning about creating pictures, and then in a little while, we will be finding out about filling a space.

Let's start by finding out about pictures.

In our lesson today, we're going to have a couple of friends who are helping us with our learning.

So today we have Aisha and Jacob.

Look out for them as we go through the lesson and see if they can help us.

Have you ever played with blocks like these? Have a look at that photo.

There are different shapes and different colours.

I have some blocks like these and they are lots of fun to play with.

I wonder if you've ever seen any blocks like this before.

Now let's have a look at the blocks that are on the screen.

These are pattern blocks, and you can see the pattern blocks are being used to make a picture.

If you keep watching, they move from where they are at the top, where they are not joined together, into the picture at the bottom where they are joined together.

And I think it looks a little bit like a picture of a cat.

Have a look at some more.

You could use the same pattern blocks to make a different picture.

This time, I think that picture might look a little bit like a flower.

What do you think it looks like? Let's watch one more time.

The pattern blocks are moving to create a picture.

And now let's look at some different pattern blocks.

If you have different pattern blocks, you can make different pictures.

This time I think the picture looks a little bit like a train.

Let's watch it one more time.

Very good.

Now what I would like you to do is have a go at creating your own picture using three different types of pattern blocks.

So I am going to use these three.

So I've chosen some yellow, some red, and some pink blocks.

If you don't have any blocks of your own that you can use, see if you can ask a grownup to cut some out for you.

Okay.

Once you've got your three types of blocks, I would like you to see if you can make some different pictures with those blocks.

If you need to pause the video to have time to do this, please pause now.

Well done.

Right, I'm going to show you the pictures that I made, and you can have a look and see if they might be similar to the pictures that you made.

So I took those three different types of blocks, and the first picture I made is this one that I think looks a bit like a car with some big, yellow wheels.

Next, I made this picture, and I think this one looks a little bit like a tree growing out of a pot.

So this time I only used one of each block and I could still make a picture.

And then after that, I made this picture.

So I made another picture that looks a bit like a cat.

We can see it has the ears and the tail and a head and a body.

So even though I only had three different types of blocks, I could make all of these different pictures.

I wonder which kinds of pictures you made.

You are going to do a quick check now to make sure that you understand how to use pattern blocks to make pictures.

If I have these pattern blocks, I want you to work out for me, which picture could I make? Could I make A? Or B? Or C? Jacob has a good idea, to try this out with some of your own blocks.

If you have some blocks or if you have some cutout blocks that an adult helped you with, you could use those now to help you decide which picture could I make with those pattern blocks.

Let's have a look what Jacob did with his blocks.

There they are.

He's found the matching blocks that I had, and then he's moved his blocks around and he has found that the picture he can make is C.

Well done if you said C.

Now we're going to learn something else that you can do with pattern blocks.

You can rotate pattern blocks to fit them against each other.

Oh, Jacob says, "I am going to rotate my blocks to fit them together." Let's watch what Jacob does with his blocks.

You ready? Let's go.

Oh, I can see Jacob's block was spinning.

It was moving round until it fitted against the other block.

Let's watch another one.

Jacob is rotating his block until it fits against the other block.

Let's watch another one rotate.

And another one.

And there is one more block that Jacob can rotate.

So each time Jacob could spin the block around, he could rotate the block to make it fit against the other blocks.

Jacob can do this in different ways, and you can do this in different ways.

If we look at the green block, we can see on the top picture it looks different to when it's on the bottom picture, because it has been rotated.

If you rotate your blocks in different ways, you can make different pictures.

So we're going to do another quick check.

I want you to look carefully at these three pictures.

Two of them have been made using the same blocks.

I wonder if you can spot which two pictures use the same blocks.

Well done.

It was B and C.

If we look at A, it's using different blocks to the other two pictures.

Did you notice that the blocks in B have just been rotated to make the new picture that is in C? There are two pink blocks and two green blocks.

They have been rotated to make a new picture.

Now, I would like you to go and try and do a little piece of work.

You can either use some pattern blocks that you already have or you can ask a grownup to help you cut some out.

You are going to use your pattern blocks to try and make the two pictures that you can see here.

Remember that you will need to join your blocks together and you might need to rotate some of your blocks as well.

You are going to go and do that bit of work now and I will see you again in a few minutes.

Well done, everybody, for trying hard to use your blocks to make these two pictures.

Let's have a look at how you could have used your blocks to make these two pictures.

Here is one way, and I can see now this looks like another kind of car with those big, yellow wheels.

And then let's look at the second picture.

Oh, this is how you could have made the second picture and I think again, it looks a little bit like a cat with those pointy ears.

Did you remember to push your blocks together so that the sides were touching? Did you need to rotate any of your blocks? I wonder if you made a different picture to this.

Could you have used different blocks to make the same picture? Now we're going to go onto our second part of the lesson where we are going to look at filling a shape.

Let's find out more about that.

Aisha has made this pattern with her pattern blocks.

This is a pattern because it follows a rule.

Usually in a pattern, blocks are repeated, so that means the same blocks will happen more than once in a pattern.

I wonder how you might describe this pattern.

You could say Aisha has used yellow blocks.

You could say that Aisha has made her pattern in a straight line.

I wonder how else you could describe it.

Jacob is going to put four of his blocks on top of Aisha's pattern.

Let's see what's going to happen with Jacob's blocks.

One, two, three, four.

Jacob says, "Two of my red blocks fill the same shape as one of your yellow blocks." Can you see that he is right? Two red blocks fill the same shape as one yellow block.

I wonder if there's any other blocks where that can happen.

Oh, let's have a look at this one.

This time we haven't got red blocks.

We've got purple blocks.

What's going to happen this time when we put the purple blocks on top? Let's have a look.

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

And now we've filled up the shape.

Aisha says, "Six purple blocks fill the same shape as one yellow block." She's right.

If I wanted to fill up the next yellow block, that means I would need six more purple blocks.

And again, at the bottom I've got one yellow block left.

That means I need six purple blocks to fill up the same shape.

Now you are going to have a go.

I have got one red block.

Which type of pattern block could you use to fill in the same shape as my red block? You can pause the video if you would like to have a little think about it.

You could also use your blocks from earlier on to try out your ideas.

Pause the video if you need to.

Okay, let's have a look.

You could use the purple triangle blocks.

Let's have a look.

How many do we think we would need to fill the same shape? One, two, three.

Well done if you said three triangles.

Now Aisha is going to use some of her blocks to fill in this empty shape.

I wonder which blocks she's going to choose to fill in her empty shape.

Let's have a look.

Oh, she has chosen to use two yellow blocks and four purple blocks to fill in the empty shape.

Jacob says, "I think I can use different blocks to fill the same shape." Oh, that's an interesting idea, isn't it? So he's not going to use the same blocks as Aisha.

He's going to choose a different block.

I wonder which blocks he's going to choose.

Let's have a look.

One, two, three blue blocks fill the same shape that Aisha filled.

Jacob was right.

You can use different blocks to fill the same shape.

I wonder if you can spot who has used different pattern blocks to fill the same shape.

I want you to look really carefully at these three pictures.

Who has used different blocks to fill the same shape? Pause the video if you need more time.

Okay, let's have a look.

It is A and C.

The picture in the middle is not the same shape, but A and C are the same shape.

Even though they've chosen different pattern blocks, the shape is the same.

They have filled the same shape.

Well done.

You are going to go and do another piece of work now, and if you don't have your own blocks, you will be able to use these ones and you can ask a grownup to help cut them out for you.

And what you are going to do with those blocks is to find out how many ways can you fill this empty shape.

Okay, so you are going to do what Aisha and Jacob did.

You are going to choose blocks to fill an empty shape, but I don't only want you to fill up one shape or two shapes or three shapes.

You are going to try and fill up as many of these empty shapes as you can and find lots of different ways with your pattern blocks.

I'm looking forward to seeing what you've done in a few minutes.

Well done.

Off you go to try and do that piece of work now.

Well done.

You have worked really hard to fill in those empty shapes.

Let's have a look at some of the ways that you might have found.

So you could have used two of these red blocks or you could have used six of the pink blocks.

You might have found that you could use one red and three pink, or you might have found that you could use three of the blue ones.

You could have found all sorts of different ways to fill this empty shape.

Each of these patterns uses different blocks, but the blocks fill the same shape.

Well done if you found different blocks that would fill the same empty shape.

Good job.

Now that we are at the end of the lesson, this is what we have found out.

Pattern blocks can be joined together to make pictures and patterns.

So if we look at the screen, we can see that some pattern blocks are being joined together to make a picture.

We've also learned that you can rotate pattern blocks to make different pictures.

You can rotate them so that they will fit together.

So again, if we watch the blocks on the screen, some of those blocks are being rotated to make them fit together.

We have also learned that you can use different pattern blocks to fill the same shape.

So if we look at the blocks on the screen now, instead of one yellow block, we could have two red blocks.

And in the place of one red block, we could have three triangle purple blocks.

And I'm sure you can spot lots of other ways that we could use different blocks to fill the same shape.

Well done for working so hard on your maths today, everybody.

You have done a really good job.

Goodbye.
