Lesson video

Hi, everyone, my name is Miss Sabzvari, and I'm really excited you decided to join me today for our math lesson.

The unit we're studying is fractions.

In the previous lesson, we focused on identifying parts of a fraction.

In this lesson, we'll be identifying half of a shape.

So when you're ready, let's begin.

Let's have a look at today's lesson agenda.

First, we'll begin by identifying half.

Then, we'll move on to a Talk Task.

After that, we'll be identifying half of a line.

And finally, you will complete your independent task.

And before we begin today's lesson, you will need some pieces of paper and something to write with.

Please pause the video now and get the items that you need.

Identifying half.

Let's have a look at the shape on our screen.

What shape can we see? Tell your screen.

Great job, a triangle.

Where might I draw a line to make two equal parts? Pause the video now and share your answer with the screen.

Great job, so.

I might draw a line in the middle here to split my shape into two equal parts.

I might decide to draw my line here and split my shape into two equal parts like this.

Or I might decide to draw my line here and split my shape into two equal parts like this.

When we halve a shape, it's really important to make sure that both of the parts are exactly the same size.

Okay, great work.

Let's have a look at the shape on your screen.

Tell the screen what shape you can see.

Great job, a square.

So where might I draw a line to make two equal parts? Pause the video now and share your answers with the screen.

Great work, so I might draw a line down the middle to split my shape into two equal parts.

Both parts need to be exactly the same.

Or I might draw a line this way horizontally, and again, both of the sides are exactly the same, they are equal, great work.

And I might split my shape into two equal parts like this.

Or I might decide to split my shape into two equal parts like this.

But however I do it, I need to make sure that both sides are of equal size, that's right.

So have a look at the shape in the middle of your screen.

Where might I draw a line to make two equal parts? Pause the video now and share your answers with the screen.

Great job, so I could split my shape down the middle.

Or I could draw a line horizontally to split my shape into two equal parts like this.

Alternatively, I could split my shape into two equal parts this way, or this way.

Great, so moving on to Talk Task.

What I would like you to do is to explore halving your sheet in different ways.

Okay, so.

I would like you to get a piece of paper that looks like this, and another piece of paper that is a square, and another piece of paper that is a rectangle, like this.

And I want you to have a go at folding the sheet and halving it and splitting the sheet into two equal parts, okay? As many possible ways as you can, and then, I would like you to choose one particular way and to shade one half of it.

Do that now.

Okay, so this is the piece of paper that I have.

Okay, so it's a rectangle, so I need to half it.

So one way that I could half it is to make sure that the edges are exactly the same, and I'm going to halve it.

I know that this side is exactly the same as this side.

Okay, so I could shade one half of it.

Alternatively, I could half my paper this way.

Again the two sides need to be exactly of the same size.

So this is one half, and this is another half.

I have a square, so I could half my paper this way because both of the sides are going to be exactly the same so no side is sticking out.

Or I could halve my piece of paper this way.

Again the two sides need to be exactly the same size.

And again, I could halve, I could shade one half.

Great job.

Did you find a different way? Great job, so identifying half of a line.

Look at this line on your screen.

What I would like you to do is to point to where you think half of the line is.

Do that now.

Point with your finger.

Great job, so were you correct? This is where half of the line is.

So we know that this is half the line because this side of the line is exactly the same length as this side of the line.

So if we fold the line, it will be identical.

I will be identical.

Good job.

So moving on to Independent Task.

What I would like you to do is to use an A4 piece of paper and to find as many different ways of halving the sheet as you can.

Please, if you'd like to, ask your parent or carer to share your work on Twitter tagging @OakNational and #LearnwithOak.

I would love to see all the different ways that you were able to halve your piece of paper.

And now, it's time for you to complete your end-of-lesson quiz.

See you next time.
