Lesson video

Hello everybody, my name is Mrs. Johnson.

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

I hope you're ready to work hard and have lots of fun.

Let's see what we're going to be learning about today.

This lesson is called Understanding Turns.

It comes from the unit position and direction, including fractions of turns.

By the end of this lesson, you will be able to recognise when something has been turned and you will be able to describe turns using left and right.

Can you remember left and right? Do you have any special ways that you remember, which is your left side and your right side? Have a think about that because it will be really important that you can remember which way is left and which way is right in this lesson today.

There are three key words that I would like you to practise.

I will say them first and then it will be your turn.

Ready, my turn, turn.

Your turn.

My turn, left.

Your turn.

My turn, right.

Your turn.

Well done.

Listen out for those words in this lesson today because they are going to be really important for your learning in this lesson.

There are going to be two parts to this lesson.

To begin with, we're gonna be thinking about this question.

What is a turn? And then in a little while we're going to be practising making left and right turns.

To begin with, let's think about this question.

What is a turn? There are two friends in this lesson today who are going to help us.

Their names are Izzy and Jun.

Watch carefully because Izzy and Jun have lots of really helpful things to show you in this lesson today.

Jun has been doing a jigsaw puzzle and he wants to finish it.

How could he make the last two pieces fit into the jigsaw? If you were building this jigsaw, what would you do to make those pieces fit? Let's see if John has an idea.

He says, "I need to turn each piece to make it fit in the jigsaw." Let's watch him do that.

If he turns each piece, it will fit into the jigsaw.

Another word for turn is rotate.

Let's watch him turn those pieces again to make them fit into the jigsaw.

Here's Jun turning the first piece and he's going to turn the second piece to be able to finish his jigsaw and make all the pieces fit.

Izzy is building a pattern with blocks.

Izzy is going to turn the blocks to extend her pattern to make her pattern longer.

Let's watch how she turns the blocks.

She can turn them to make them fit so that she can carry on building her pattern.

I wonder if you've ever made a pattern with blocks before.

Did you have to turn them to make the pattern that you wanted a bit like Izzy? Let's check if you can spot which piece of the jigsaw needs to be turned to be able to finish this jigsaw.

Do you think it's A, B or C? You can pause the video, have a little bit longer to think about it.

Let's have a look.

The piece that needs to be turned is B.

Let's watch Jun complete his jigsaw.

A does not need to turn.

It can slide straight in.

C is the same.

It doesn't need to turn, it can slide straight in and it's the right way up to join the jigsaw puzzle.

It does not need to be turned.

If Jun slides B into the jigsaw, it doesn't fit, does it? You can see that's not the right way around.

That jigsaw piece doesn't fit.

It needs to be turned.

So let's watch Jun turn it and now it fits in and the jigsaw has been completed.

Can you see Jun now? He's standing in the middle of these things.

There's a house and a tree and a slide.

Jun is facing the tree.

How could he face the slide? What would he need to do? Jun's got an idea.

Let's see if you are thinking the same as Jun.

He says, "I need to make a turn." And there he is now he has turned.

He's facing the slide.

When you turn or rotate something, you are making a rotation.

Jun is making a turn.

Do you think you could make a turn too, a bit like Jun? Perhaps you could stand up and you could turn around by moving your feet.

Izzy could make a turn with one of her blocks.

Depending on how much she turns it, it could look different, couldn't it? Let's check if you can spot when something is making a turn.

True or false? This shows a turn.

I'll let you watch it for a few more seconds.

Do you think this is showing a turn? It is, well done.

This triangle is making a turn.

What about this one? True or false? This shows a turn.

I'll let you watch it one more time.

This is false.

It's moving in a straight line.

There is no turn.

What about this one? True or false? This shows a turn.

This one is true, well done.

The number shape has been turned.

There is one more for you to think about.

True or false? This shows a turn.

This time it is false.

This number shape doesn't show a turn.

The number shape has been added to.

There were nine blocks in the number shape and now there are 10 blocks in the number shape.

It has not been turned.

Now it's time for you to go and do a little bit of practise.

You are going to think really carefully about turns.

Jun had a number shape and he turned it and now this is what it looks like.

Your job is to think really carefully about what do you think the number shape looked like before Jun turned it.

I would like you to draw your ideas.

What could that number shape have looked like before Jun made a turn? You're going to draw your ideas now.

Off you go.

You could have drawn lots of different things when you were thinking about Jun's number shape.

It could have looked like this, but maybe it could have looked like this.

In fact, it could have looked like any of these and there are even more.

The important thing that you needed to make sure is that you don't change the shape.

Jun didn't make his number shape a different number.

He didn't make it bigger or smaller.

All Jun did was turn it around.

So make sure that you have drawn the same shape.

It just looks like it has been turned.

Well done, if you thought carefully about that.

Now it's time for the second part of the lesson where we are going to be thinking about left and right turns.

Jun has used chalk to draw a path on the ground for Izzy to follow.

What do you think is going to happen when Izzy follows the path? She could start walking and following the path, but when she gets to here what is going to happen? Jun knows, Jun says, "You need to turn right." Well done if you were thinking about that too.

Izzy's got to the end and she can't carry on until she makes a turn.

Izzy needs to turn right and then she can carry on and get to the end of the path.

You can make turns in different directions.

You can turn left like this and you can turn right like this.

Which car makes a left turn? Watch them carefully.

I'll let you watch them again.

One of these cars is making a left turn.

I'll let you watch one more time.

Which car do you think is turning left? Making a left turn? Pause the video if you need a bit longer.

The car making a left turn is B.

B is turning left.

A is making a right turn.

It is turning right.

Now Jun has drawn a longer path for Izzy to follow.

Izzy's going to walk along the path.

She's facing this direction and she needs to face this direction to follow the path.

She needs to turn this way and that is a right turn.

So Jun says, "You need to turn right." Izzy is going to turn right, carry on.

She's still following the path now she's got to the next corner.

She's facing this direction and she needs to face this direction.

Let's imagine that as a turn.

This is the direction she needs to face.

She needs to turn this way.

Jun says, "You need to turn left." That is a left turn.

Izzy has turned left and she will carry on.

Now Izzy is facing in this direction.

She wants to face in this direction so she needs to turn.

Which way do you think this time? Jun says, "You need to turn right." Well done if you were thinking right as well.

She's got one more corner.

She is facing this direction.

She needs to face this direction.

Let's imagine those arrows turning.

Which direction are they turning? They are turning this way.

That means you need to turn right.

Well done if you were thinking right as well.

Oh, we thought she'd got to the end, but now Jun has made the path longer.

Let's check if you can think about whether Izzy needs to turn left or right.

Let's think about those arrows again.

Izzy is facing in this direction and she needs to face this direction.

Let's watch the arrows turn.

They are turning this way.

Pause the video and have a think.

Does Izzy need to turn left or right? Izzy needs to turn left to get to the end of the path.

Well done if you said left.

Now it's time for you to do a little bit more practise.

Izzy wants to walk along this rope without falling off.

I would like you to describe the turns that she needs to make.

When she gets to each corner, should she turn left or right? You're going to think about that really carefully.

If you finish, I want you to do something really fun.

I want you to create your own pathway for one of your toys to follow without falling off and I want you to think about the directions of the turns.

Does your toy need to turn left or right to be able to follow the pathway that you've made? You are going to try and go and do that work for me now.

Off you go.

Good job everybody.

For Izzy to follow this rope without falling off, these are the turns that she needs to make.

She needs to turn left, turn right, turn right, turn right, turn left.

Turn left, turn right.

Well done if you were able to think about whether Izzy needed to turn left or right each time.

Some of you might have thought about making a pathway for one of your own toys.

This is what Jun did.

He made a pathway for his toy car and he described the turns.

The car was driving along the path and it had to turn left and then it had to turn right.

Well done if you could make your own pathway and you could talk about whether your toy was turning left or right each time.

Good job.

At the end of the lesson you have learned that when you turn or rotate something, you are making a rotation.

You know that you can turn things like jigsaw pieces and pattern blocks.

You can even turn yourself.

You can turn left and you can turn right.

Well done for thinking so carefully about turns today.

You have worked really hard and done a very good job, well done.

I hope that I will see you again soon for some more maths learning, bye everybody.
