Lesson video

Hello there.

My name is Mr. Goldie, and welcome to today's lesson.

I'm sure you are going to have lots of fun.

Welcome to the lesson.

In our lesson today, you are going to learn what zero means and you're also going to know how to use it.

And here are our key words for today's lesson.

Just two key words today.

The first word is zero.

Can you say that? Zero.

And the second word is represent.

Can you say that word? Represent.

Excellent.

Now, the word zero means nothing.

It means when you've got nothing left, when there is none left at all, when it's all gone.

And the word represent, we use that to show something, when something stands for something else.

And here is our lesson outline.

Our lesson today is called Introducing Zero.

And there are two parts of the lesson today.

In the first part, we are going to be counting using zero.

And in the second part, we are going to be recognising zero and know when we use zero.

So, let's start with the first part, counting using zero.

In the lesson today, you are going to meet Sophia and Andeep and they're going to help you with your learning.

So, let's get started with a song.

And this is a song you might know already.

It's called "Five Little Speckled Frogs." If you know the song, you can join in.

And if you don't know the song, join in as soon as you can.

Are you ready? It goes like this.

♪ Five little speckled frogs ♪ ♪ Sat on a speckled log ♪ ♪ Eating the most delicious bug, yum, yum.

♪ ♪ One jumped into the pool ♪ ♪ Where it was nice and cool ♪ ♪ Now there are just four speckled frogs, glub, glub ♪ ♪ Four little speckled frogs ♪ ♪ Sat on a speckled log ♪ ♪ Eating the most delicious bugs, yum, yum ♪ ♪ One jumped into the pool ♪ ♪ Where it was nice and cool ♪ ♪ Now there are three speckled frogs, glub, glub ♪ ♪ Three little speckled frogs ♪ ♪ Sat on a speckled log ♪ ♪ Eating the most delicious bugs, yum, yum ♪ ♪ One jumped into the pool ♪ ♪ Where it was nice and cool ♪ ♪ Now there are two speckled frogs, glub, glub ♪ ♪ Two little speckled frogs ♪ ♪ Sat on a speckled log ♪ ♪ Eating the most delicious bugs, yum, yum ♪ ♪ One jumped into the pool ♪ ♪ Where it was nice and cool ♪ ♪ Now there is one speckled frogs, glub, glub ♪ ♪ One little speckled frogs ♪ ♪ Sat on a speckled log ♪ ♪ Eating the most delicious bugs, yum, yum ♪ ♪ It jumped into the pool ♪ ♪ Where it was nice and cool ♪ ♪ Now there are no speckled frogs, glub, glub ♪ How many frogs are on the log? How many frogs are still sitting on the log? What do you think? There are no frogs left on the log.

They've all gone.

There are none left.

How else can we say that there are are no frogs? Is there a number to show that there are no frogs? There are zero frogs.

And here's Andeep to help us.

And he tells us that zero is the number that represents no amount or no objects.

So, we can use zero when there is nothing left.

And you can write the numeral zero like this.

That's what zero looks like.

Let's represent the number of frogs throughout the song, using our fingers.

So, let's start off by holding up five fingers.

And Sophia tells us we're going to count backwards from five to zero.

So, you ready? So, we're going to start from five and we count backwards.

You ready? Say five, four, three, two, one, zero.

Now the frogs ate the most delicious bugs.

How many bugs can you count? Can you count the bugs sitting on the lily pad? Can you count them up? How many do you think there are? Did you say five? Well done if you did.

Now, we're going to count the bugs as they fly away.

Use your fingers to represent the number of bugs.

So, just like the frogs jumping off the log, hold up five fingers and you're gonna put down a finger every time, one of the bugs flies away.

Are you ready? Here's Sophia again.

She's telling us to count backwards from five to zero.

Are you ready? Let's say five, four, three, two, one, zero.

Fantastic.

Now if the frogs jump back on the log, what would our count look like? Now, this time we're going to start our count at zero and we're going to count upwards.

So, we're going to count.

Zero.

One, two, three, four, five.

Excellent.

Now, can you count the frogs as they jump off the log? This is one for you to try on your own.

So, Andeep is going to help you, but see if you can count as the frogs disappear.

Are you ready? There's Andeep.

So first of all, count up the frogs on the log.

How many frogs are there altogether? Have you counted them up? Pause the video if you need to and let's get started.

So, you should start with seven and then count back with some seven.

Are you ready? Excellent.

Well done if you said every number and you got all the way to zero, fantastic work.

Now, sometimes something happens when we reach zero.

When the frogs jumped off the log, we just have no frogs left.

But sometimes something happens, like when a rocket is blasting off, we are going to count backwards to the rocket blasting off.

Here's our rocket.

It's getting ready to launch and here's Sophia.

And Sophia is saying to us, let's start our count at five.

So, we're going to start counting at five and we're gonna count back to zero.

And when we get to zero, the rocket blasts off.

Are you ready? So, let's start off with five, four, three, two, one, zero.

Fantastic.

Now here's one for you to try on your own.

You're going to count backwards to the rocket blasting off.

This time you're going to start your count at 10.

So, you're gonna start from 10 and you're gonna count back all the way to zero.

And you're gonna see if you can say every number in the right place.

Are you ready? Get ready.

So, we can start from.

Fantastic.

Did you say every number? Did you get to zero? Did you remember to say zero when the rocket blasted off? Fantastic if you did.

Now it's time for our task.

You are going to work with a partner.

So, you can work with a friend or a brother or sister or a mum and dad or somebody else who looks after you, even work with your cuddly toy, although you might need to help them with the numbers.

Here's Andeep and Sophia, and they're going to work together.

So, they're going to be partners.

You are going to start with one of these numbers.

So, you can start with number five or six or seven or eight or nine and you're going to take it in turns to count backwards from that number.

So, Andeep is gonna start us off.

He said five first of all.

So, Sophia's gotta count backwards from there.

So, she says four.

So, Andeep says three.

Sophia says two.

Andeep says one.

Now if you say zero, you're going to jump up like a rocket.

Or if you don't want to jump up, you can put your arms up in the air.

So, Sophia says zero 'cause it's her turn next and she jumps up like a rocket.

So, pause the video and play that game with a partner.

Did you play the game? Now hopefully your learning looks a little bit like this.

So, Andeep chose a different number and this time he chose eight and so they've gotta count backwards from eight.

So, Sophia says seven and Andeep says six.

Sophia says five.

Andeep says four.

Sophia says three.

Andeep says two.

Sophia says one.

And this time Andeep jumps up like a rocket and says zero.

Welcome to the second part of the lesson.

And in the second part of the lesson, you are going to be recognising zero.

Now, this is our first question and it says, "Can you spot which log has zero frogs?" "Can you spot which log has zero frogs?" Can you spot it? Can you see which one has zero frogs? And if you can find the one that has zero frogs, how many frogs are there on the other logs? Can you count them up? Pause the video and count the frogs? Did you count them? Do you think you got it right? Let's see if you were actually correct.

The first log has two frogs on it.

The next log has four frogs and the last log has zero frogs.

Well done, if you've got all of those ones right, let's look at our next question.

Can you spot which log has zero frogs now? Can you spot which log has zero frogs now? So, I think the frogs have been jumping around a bit and they've moved logs and I think a few more frogs have turned up as well.

So, which log has zero frogs on it? And how many frogs are there on the other logs? Count them up carefully.

Pause the video and see if you can work it out.

Shall we see if you've got it right? So, our first log has six frogs on it.

Our next log has zero frogs.

There are no frogs at all.

And our last log has five frogs.

Well done if you've got all those ones right as well.

Now our next question says, "can you spot which lily pad has zero bugs?" "Can you spot which lily pad has zero bugs?" I think this might be a bit of a trick question, 'cause here comes Andeep to help us out a bit.

There are two lily pads that have zero bugs.

Can you spot which two it is? Have you got them? Shall we see if you were right? This lily pad and this lily pad, they both have zero bugs.

Now, here's a question for you to try on your own.

And the question says, "Which log has zero frogs?" "Which log has zero frogs?" Pause the video if you need to work out the answer.

Shall we see if you got it right? The answer is B.

B has zero frogs.

There are some bugs on the log, but there aren't any frogs.

The next question to try on your own is this one here, true or false? There are zero frogs, there are zero frogs.

Is that true or is it false? Pause the video if you need to work it out.

Shall we see if you got it right? The answer is true.

And here's Sophia to explain.

She says there are lots of bugs, but there are zero frogs.

There are no frogs at all.

And now we're onto our task.

And in this task here, you are going to be matching pictures to the numerals that represent them.

And it says, "How many frogs are there?" "How many frogs are there?" There they are, here's a picture of some frogs and here's a numeral.

Do they match? Does that numeral represent that number of frogs? Well, the numeral says five.

How many frogs are there in the picture? There are five.

So, those two match together.

That's fantastic.

And this one here, we've got three.

And how many frogs have we got? Three frogs.

Those ones also match.

So, we've got to match the pictures and the numerals to represent them.

And if you manage to do that, there's a second task to do.

So, there's a game you are going to play and it's a pairs game.

You're going to play with a partner.

So, what you do is you turn all the cards face down, so you can't see the pictures and you can't see the numbers.

And then you take turns to choose two cards.

And if they match, you get to keep them.

So, here's a picture and here's a number.

Do they match? Well, we've got the numeral five and we've got three frogs.

They do not match, okay? So, this one here does not match, so you wouldn't keep them.

So, we turn them back over, so we can't see them anymore.

And then our partner would have a go at trying to match a picture and a number.

But you might turn over this one here and this one here, and we've got the numeral five and five frogs.

They do match.

So this one here, we'd keep and then our partner would have a go and see if they can find the two that match as well.

So it's a bit of a memory game as well as a matching game.

It's a good fun game that one.

And here are the answers.

So, you can see the pictures of logs and frogs and the number, the numeral that matches them.

So, hopefully you've got all of those right and you manage to match them all up together.

So very, very well done.

And here is the summary of the lesson.

It's tells us what we learned in today's lesson on introducing zero.

So, we've learned that zero is the number that represents no amount or no objects when there's nothing left at all.

And you can write the numeral zero like this.

That's how you write it.

Very well done.

I hope you enjoyed today's lesson and some of the games that you played.

And hopefully now you'll remember what zero is and you'll know what it looks like as well and you'll know when to use it.

Very well done indeed.
