Lesson video

Today we are learning to identify one half of a shape.

Hello, everybody.

It's Ms. Sidhu here, and welcome to today's lesson.

In this lesson, we will be exploring what equal and unequal means and finding half of a shape or dividing it into two parts.

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

Welcome to today's lesson.

You will need some pieces of paper, a range of single items of foods such as banana, a cupcake, a potato, and carrots that we can cut in half.

And the last item you need is a loaf of bread and some child-friendly knives so we can cut our fruit and our objects and bread in half.

You may need an adult to help you to cut.

We are going to be looking at key vocabulary and that's our star words, exploring what equal and unequal means.

Finding half of a shape, an independent task and answers, and finally a quiz to see everything we have learned.

Now, there were some times during the video, when I will ask you to pause the video, to have a go at some of the activities.

Now let's get started.

Star words! Star words! My turn.

First.

Then your turn.

Part.

Whole.

Equal.

Unequal.

Half.

Divide.

Oh, today we have a brain teaser to warm up our brains, Double trouble.

I want you to choose a number and double it.

I want you to pause the video, have a think and then tell the person next to you.

How did you get on? Let's go through all of the answers.

Now, double one.

I want you to just shout out the answer or point to it on your paper.

Double one is two! Double three is Six! Let's try.

Double eight is 16.

Double, which one should we do next? Double four, is eight and double two is four.

Wow you've impressed me so much today already with all of your doubling knowledge.

Now let's have a look at what is next.

I have two pieces of paper here.

What is the same and what is different? So I have a piece of paper.

I folded this paper and drawn a line down the fold like this.

I have folded this paper and drawn a line down the fold.

What's the same and what is different? Can you say it nice and loud.

I can hear lots of different answers.

Somebody says that one of the pieces of paper have the same part, they look the same.

And I heard somebody using one of us star words which said unequal.

And they said, this paper, the line here has unequally had two different parts.

How do you know it is half? While the hole is divided into two equal parts.

So we've got our two equal parts, one part, two parts.

And they're both the same, same, same matchy-matchy.

Now I want you to help me for this activity.

You need some pieces of paper to cut into shapes, such as squares or rectangles or even circles.

A little bit like I have done.

Can you fold the shapes to show two equal parts? And can you fold the shapes to show two unequal parts? I think the shape has been folded to roughly two equal parts because the edges are close together, and making the two parts equal.

Hmm, I think the shape is folded into two unequal parts because the edges do not line up and there is an overlap.

Now I want you to pause the video, pause and freeze, macaroni cheese.

I hope you had fun.

Finding out all about the shapes and finding equal parts and unequal parts.

Now, here is our big picture of Nancy, the spider and turtle let's have a larger picture more carefully.

Can you point to the cupcakes? I said those first, because those are my favourite.

Now can you point to the carrots? What about, can you point to the crab that's hiding under the table? Can you point to the potato? and now can you see the potatoes that are in the green bowl next to our Nancy? Wow, that was super fast.

Now that's one of Nancy's potatoes, but we need to share it between Nancy and turtle How many parts will we need? That's right we need two parts.

One part for Nancy.

One part for turtle.

Now how can we make it fair? Have a think, how can we make it fair? I know we can make it fair, but cutting it into two equal parts.

Let's say together, cutting it into two equal parts.

But how will we know it is half? Hm, well, I have lots of you telling me it will be half because the whole will be in two equal parts.

Now for this activity, you may have some items at home like a carrot or banana, or even a cupcake to share between Nancy and turtle, have a go and finding half of an object, ask an adult to help you and be careful.

Remember, half is the whole split into two equal parts.

If you haven't got any objects, then you can draw them on paper and then cut them in half.

Or you can use play dough and you can put them split the play dough into two equal parts.

When you are doing your activity, I want you to think about how many parts will we need? How can we make it fair? Where would we need to cut it to assure we cut it in half? At home I have got some strawberries.

There's my strawberry.

And I need to find half of my strawberry so I could do in half.

I've got two equal parts.

Both the strawberries are the same amount, same, same, matchy-matchy.

I also had a go and I had a tomato and I need two parts to share between Nancy and turtle and to make sure that it was equal parts I cut it right in the middle and super careful.

There's my tomato.

And there's the two parts.

So I cut it in half.

And then my two equal parts.

So you can have a go at different items at home as well.

I want you to pause the video and have a go.

Your task today is to explore cutting the slices of bread in half.

You will need a loaf of bread so that you can experiment and explore.

If you haven't got any bread, you can have a go at drawing a picture on a piece of paper, of a slice of bread, and you can have a go at cutting the slices in half.

Now how many ways can you cut a slice of bread in half? How many ways can you show the slice not being cut in half? And how do you know? I hope you have lots of fun with cutting the bread in half.

Now I want you to pause the video so you could have a go at exploring.

How did you get on, did you have lots of fun? Here are some of the ways you can show half.

You might have shown some other ways but as long as they, as long as you've split the whole into two equal parts.

Now I know that you have done some amazing work, make sure that you have taken some pictures of you cutting your slices of bread in half.

And I want you to share your work with Oak National.

Please ask your parent or carer to share your work on twitter, tagging @OakNational and hashtag learn with Oak so that I get to see all of your amazing work that you've been doing.

Great exploring halves today.

And don't forget to complete your end of lesson quiz.

Bye.
