Lesson video

Hello everyone, it's great to see you today.

I hope you've had a really good start to your day.

Do you know, I've had a great start to my day.

I've been busy looking around for all the toys that got lost, and I have found some.

Do you want to have a look and see what I found? You might recognise these toys.

Take a look.

Here they are.

Do you know what they're called? Shout out the answer if you do.

Great, they're marbles.

Can you see how many I've found? Have a go at counting them, and shout out the answer when you know how many there are.

I can hear some great counting.

Fantastic, let's count them together.

One, two, three, four, five, six, seven, eight, nine, 10.

There are 10 marbles.

That's how many I've found.

I'm sure there might be some more.

Look, there we go.

I've got a friend here, it's Reggie.

Hello Reggie, can you say hello to everyone? Reggie says, hello everyone.

Reggie, oh, you've seen my marbles? You'd like to share them with me.

You'd like to have half of my marbles.

Let's take a look.

Do you think you can help me give Reggie half of my marbles? How many marbles do I need to give him? Let's take a look.

So here we go.

Here's the marbles.

I've got two plates here, but I need to figure out how many I need to give Reggie, for him to have half.

Now remember, how to sharing an amount of objects or quantities into two equal groups.

So let's have a look.

How do I share my marbles into two equal groups? Shout out some suggestions if you know.

I can hear a lot of you shouting out some great suggestions.

Let's see.

So if I put one mobile over here, it doesn't look like we have the same amount.

I would still have more.

Let me add another marble over here.

Reggie would have two, and I would have one, two, three, four, five, six, seven, eight.

Hmm, are those equal groups? No, do we have the same amount? No.

Then let's keep going.

There we go.

Reggie would have three and I would have one, two, three, four, five, six, seven.

Still not equal, and it doesn't look equal either.

Here we go.

There we are, I think we're nearly getting there.

Can you count them with me? One, two, three, four, for Reggie, and one, two, three, four, five, six.

Not quite, still haven't found half of 10.

You keep going.

Oh, I think we might be there.

One, two, three, four, five, for Reggie.

One, two, three, four, five, for me.

Half of 10 is five.

They've been shared into two equal groups.

There we are.

I think Reggie is going to be happy with that.

Are you happy, Reggie? Yes.

I'm sure he'll have fun playing with those marbles a bit later, right.

Moving on to today's learning.

For today's lesson, We're going to be looking at addition and subtraction.

Here's what you will need.

You will need, 10 objects for counting and a tens frame that looks a bit like this.

And if you want to explore counting with more objects than 10.

If you want to go up to 20, you'll need 20 optics for counting, and two tens frames that look like this.

Press pause now, to go and get those things, and I'll see you in a bit when you are ready.

Welcome back everyone.

Now that you've got your objects for counting, and you tens frames, you are ready for today's learning.

Let's take a look and see what we're going to be doing.

So here we are, here's our tens frame.

But for today, it's going to be a vehicle car park.

Have a look and see how many vehicles are going to enter the car park.

You can count them as their parking, have a go.

There we are.

The vehicles have now been parked.

Can you see them? How many vehicles can you see in the car park? It's a bit of a squeeze there.

They've had to park really carefully.

How many vehicles can you see? Shout out the answer when you know.

Excellent, I can hear a lot of you shouting out the answer.

Let's count them together.

One, two, three, four, five.

There are five vehicles parked in the car park.

Have a look and see what's going to happen next.

Another car vehicle, and another vehicle has pulled up on the road.

They want to join the car park.

How many vehicles will there be altogether in the car park when these two vehicles park inside? So we have five vehicles already in the car park, how many vehicles would they be all together if another two joined? Have a think.

Should out some suggestions, when you know.

You might use your fingers to help you, or you can count the objects that you see.

I can hear a lot of you working out the answer.

Let's look at it together.

We can also write out the sum on a piece of paper or a board.

So here we are.

We've got five objects already in the car park.

We want to add another two objects.

How many will there be all together? Let's take a look.

One, two, three, four, five, add two, is equal to five, six, seven.

Five add two equals seven.

Did you get it right? I'm sure that you did, give yourselves two claps.

Amazing work every one.

Now let's take a look at our car park again.

We've got seven vehicles in the car park.

I think there's going to be some more.

Count how many join.

One and two.

How many vehicles can you see now? I can hear some great counting happening.

Let's take a look and see what that looks like and the sum.

So we've got seven vehicles in the car park, and we added two more.

How many are they all together? Now there are nine vehicles in the car park.

Seven add two equals nine.

First, there were seven vehicles and then two more vehicles entered the car park, and now there are nine vehicles parked in the car park.

Great job, everyone.

But listen, I think something's going to happen.

I think that some people have finished doing their shopping and want to leave with their shopping to go home.

Let's see how many people are going to leave.

So if we take a look now, we've got nine vehicles in the car park.

See if we can write that.

Nine vehicles in the car park.

See how many leave, Keep your eyes peeled.

See if you can count them as they leave.

There we are, three vehicles left the car park.

So we're going to take three away.

How many vehicles are left? Shout out the answer to the screen if you know.

I can hear a lot of you shouting out the answer.

Let's count them.

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

Six vehicles are left.

See if you can read out the sum with me.

Are you ready? Nine take away three equals six, excellent.

Nine takeaway three equals six.

First there were nine and then three left.

So, first they were nine vehicles, then three vehicles left.

And now there are six vehicles.

Great job everyone.

Do you think everyone's going home? No, there are still some vehicles in the car park.

Let's take a look and see if any more left.

Here we are.

Keep your eyes peeled.

I wonder if you can count how many vehicles are leaving.

There we are.

How many vehicles left the car park? Great job everyone, let's count them together.

One, two, three, four.

So first there were six vehicles in the car park.

Then we have have to take four away, because four vehicles left.

How many vehicles are still in the car park? Take a look and shout out the answer to the screen when you know.

Great, two.

Six subtract four equals two.

Can you say that? Great job everyone.

Excellent.

You have just been learning about addition and subtraction.

You've been adding and taking away.

Give yourselves two claps.

Amazing, now it's your turn.

Practise adding and taking away using your tens frames, and your objects.

You can practise with objects up to 10, and up to 20.

Maybe you could make up a story for why your objects are being added and taken away.

Keep going and keep practising , and I'll see you again next time.
