Hi friends, it's Miss Molnar here and we're going to be doing some learning.

In this lesson, we're going to learn about how to combine two groups together to add.

Alright, let's see what you're going to need for this lesson.

For this lesson, you will need number cards labelled from zero to five, a Part Whole Model.

You can find both of those things in the resources, as well as some objects to count with.

I'm going to use cubes today, but you can use whatever you have at home to help you count.

Okay, pause the video now, get what you need, and we can get started.

Alright, I thought we could start off today by playing a game.

I thought we could play 'I spy'.

Have you played that game before? Wow.

I know someone who loves to play 'I spy' and he's going to come join us today.

It's Harold the hedgehog.

Say hi everyone to Harold.

'I spy' is one of Harold's favourite games.

Okay, let's get started.

Alright.

'I spy' Harold is going to go first.

Okay, Harold says I spy with my little eye, something that there is one 'F' in the picture.

I'm going to look to see if I can find something that there is only one 'F'.

Okay, I've spotted something, I spy that there is one yellow rose.

Did you see the one yellow rose? I also see one bench.

Did you see that as well that there's one bench? I wonder if you saw anything else in the picture, that there was one 'F'.

Alright, It's my turn everyone.

I spy with my little eye, something that there is two F in the picture.

Pause the video and see if you can find something in the picture, where there are only two of them.

Have a go pause the video now.

Alright.

Let's see what there could have been two F.

I spy that there were two trees, that were a circle shape.

That's what Harold saw as well.

I also spied that there were two light-green trees.

Is that what you saw, or did you see something different? Well done everyone.

Alright, let's get started with our new learning.

Harold has some friends in his classroom.

In his classroom, there are two boys.

There are also three girls.

Hmm, I wonder how could we find out, how many children are in Harold's class all together? What do you think we could do? Wow, if you said we could count them all, your right.

So there are two boys in the class and that is one part, two is a part.

We also know that there are three girls in the class.

three is another part.

If we put them together, if we combine them, then we can find out how many children there are all together.

Let's see if we can count together to find the whole.

Ready? One, two, three, four, five.

There are five children all together.

Five is the whole.

So what we've just done, is we have combined two parts.

We combined the two boys and the three girls to find how many children all together.

We added them together.

I think we can try another one, don't you? Alright, let's have another go.

This time we've got some animals.

So we have two fish.

So that means two is one part.

We also have two cats.

So two is our other part.

Alright, so now we need to combine them together.

We need to count them all to find our whole.

So let's find how many animals there are all together by counting.

One, two, three, four.

Four is the whole, or there are four animals all together.

Huh, what's that? Well, Harold thinks you did such a good job at adding two parts to find a whole, that you can have a go at one on your own.

So what you're going to do, is you're going to pause the video, and you need to find out how many animals there are all together on the screen.

You can use the sentence stem below to help you explain what the parts are, and how many there are all together.

Okay, pause the video now and see if you can tell us how many animals there are all together.

Alright, let's see how many animals they were all together.

You can say it out loud with me if you like.

Three is a part because there are three rhinos, well done.

One is the other part because there's one sheep.

There are four all together, or four is the whole.

Fantastic effort everyone.

Alright, we're back to our picture that we started with.

We want to find out, how many roses there are all together.

We've got red roses, and we've got yellow roses.

We going to show you how you can figure out how many roses there are all together, by using your counting objects.

Alright.

I'm going to use my Part Whole Model to help me find out how many roses there are all together.

You can find a Part Whole Model in the worksheet resources as well.

Alright, how many red roses were there? There were three of them, so I need to get my counting objects to represent three red roses.

So I've got one, two, and three.

I'm going to put them together, and I'm going to put them into one part.

Now, do you remember how many yellow roses there were? There was one yellow rose.

So I'm going to use my counting object to represent my other part.

So I've got three, as a part, and I've got one as a part.

Now, remember I need to put them together to add them to find out how many roses there are all together.

So, I'm going to put my three and my one together to find my whole.

Let's count them to find out how many flowers in total.

Ready? One, two, three, four.

There were four flowers all together.

Four is my whole.

We can also use the word plus to explain how we're adding them together.

So three plus one equals four.

Alright, I think we can do another one.

This time, we're going to find out how many trees are there all together, in this part of the picture.

We're going to use our counting objects again, and I'm going to show you how to represent the three triangle trees and the two circular trees, using our Part Whole Model.

Okay, let's do it together.

Alright.

So, I'm going to get my counting objects and I need to represent my parts.

Remember that there were three trees that were shaped like triangles.

So I'm going to count out three of my counting objects.

One, two, three.

I'm going to put them together and make them one part.

There was three triangle-shaped trees to be one part.

Do you remember how many circle-shaped trees there were? That's right, there were two circle-shaped trees.

So I'm going to count out my objects, One, two, to represent my two trees, and I'm going to put them in the other part.

Do you remember what we need to do next with our two parts? That's right, we need to add them together to find our whole.

So I'm going to take my one part three, and my other part two, and I'm going to put them together, to find my whole.

So let's count all together to find out how many trees.

Ready? One, two, three, four, five.

There are five trees all together.

Five is the whole.

We could also say three plus two is equal to five.

Well done everyone.

Alright, we thought you were so good at helping us that now it's your turn to have a go at this activity.

You're going to need your number cards your Part Whole Model, add some counting objects now on the worksheet to help you.

So, you're going to choose two numbers, and you're going to represent each number with your counting objects.

Place them into two parts, then you're going to add them together to find your whole.

Remember to count how many all together, then you could even say the sentence stem below to help you explain.

Alright, pause the video now.

Have a go at that and we'll come back together to see how you've done.

Alright, how did you get on everyone? Well, shall we do one together? Alright, so the two number cards I chose to add together are five, and three.

So, I need to represent both of the parts using my cubes.

So I'm going to count out my five first.

So I've got one, two, three, four and five.

Five is one part.

Now I need to get my other counting objects to represent my other part.

So I've got one, two, and three.

Three is my other part.

Five is a part three is a part.

Hmm, now I need to add them all together.

So I can say, five plus three is equal to remember, I need to put them together and count them to find my whole, to figure out what they are equal to.

Let's count them all together.

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

Eight is my whole.

So I could say, five is a part three is a part, five plus three is equal to eight.

Well done everyone.

Now, I wonder, could I have shown my parts the other way and still get the same answer, or is it going to be different? Hmm, let's try saying it the other way.

So I could say three is a part, five is apart.

Let's add them together and see if we get something different this time.

Shall we count again, One, two, three, four, five six, seven, eight.

So three plus five is equal to eight.

Five plus three is also equal to eight.

The whole is still the same, we've just put the parts in a different place, but as whole is still the same.

Fantastic job today everyone.

Well, that brings us to the end of today's lesson.

A very big well done and all the fantastic learning you've achieved today.

Harold and I both thing you deserve a high five, give her the high five.

If you're able to, please take a picture of your learning and ask your parent or carer, to share it with your teacher, so they can see all the fantastic things that you've done today.

And if you'd like, you can ask your parent or carer to send a picture of your learning to @Oaknational on Twitter, so we can see all of your lovely learning as well.

Alright, that's all for today everyone.

Take care and see you again soon.
