# Lesson video

In progress...

Hello everyone, I hope you're ready for some great learning.

Before we get started, I'm going to sing you a little song.

It goes a little bit like this.

♪ Hello number one ♪ ♪ Are you ready to have fun? ♪ ♪ Hello number two ♪ ♪ How do you do? ♪ ♪ Hello number three ♪ ♪ As happy as can be ♪ ♪ Hello number four ♪ ♪ And then we go one more ♪ ♪ Hello number five ♪ ♪ I'm glad that you've arrived ♪ ♪ Hello everyone let's go and have Maths fun.

♪ Now, today's lesson is going to be a little bit different.

We're going to be practising some of the math skills that you may have learned already.

So, before we get started, I want you to stand up, have a little jig, switch your math brain on and sit down and let's get started.

Are you ready? Let's take a look at the screen.

So, I have a number line here.

It's got numbers all the way from zero up to 20.

Your first job is going to be to tell me one more than the number that I give you.

Here's a little practise.

So, here's five, one more than five is six.

Are you ready? You're not going to have long to answer these, you've got to be quick.

Here we go.

Great and what is one more than nine? Shout your answer out.

Amazing work everyone.

Well done, you're doing very good with one more than.

Now, I'll put the number line back and we're going to do one less than.

Here's how that works.

So, if I put my finger on number 10, do one jump back, one less than 10 is nine.

Here we go.

Great, what is one less than four? Shout out the answer.

Fantastic and here we are, last one.

Fantastic, well done everyone.

Give yourselves two claps for great work doing one more than and one less than.

Now, let's take another look at the screen.

Going to do some work.

Counting in twos.

Here we are.

Two, four, six, eight, 10.

There we go.

Our numbers all increase in twos.

I'm going to take one away now.

Let's see if you know what number is missing.

Shout the answer out when you know it.

What number is missing? Great, I can hear a lot of you shouting out the answer, the number six was missing, well done.

Here we go again.

I'm going to take another number away.

What number is missing? Remember, we're counting in twos.

Two, four, six.

What number is missing? Shout the answer out.

Eight, eight was missing.

Two, four, six, eight, 10.

Well done everyone, last time.

What number is missing? What number is missing? Shout the answer out when you know, great.

Four, four was missing.

Two, four, six, eight, 10.

Well done everyone.

That was some great counting in twos.

Now, let's take a look at my dice.

I'm going to hold my die up to the screen and let's see if you can count how many spots there are on the face that I show.

Are you ready? You've got to be quick.

Here we go, how many? Great, let's try again.

How many? Well done everyone.

You're doing really good at this, how many? Excellent and the last one, how many? Well done everyone.

That was great.

That was called subitizing.

That was you counting how many spots you can see by looking at the way the spots are placed on the face of the dice, well done.

Now, let's take a look at the screen again.

I'm going to show you two bowls and you're going to tell me which one has more and which one has less.

Are you ready? Which bowl has more? This dark orange one or the light orange one? Great, the light orange one.

Excellent, well done.

Let's try that again.

Which bowl has more? The dark orange one or the light orange one? Great, the dark orange one, excellent.

Let's try it again.

Which bowl has more? The light orange or the dark orange one? The light orange one.

You're doing great at this.

Now, we're going to change what we're doing.

Let's see which bowl has less.

Which bowl has less cubes? The light orange one or the dark orange one? Which bowl has less? Great, the light orange one has less cubes in it.

Well done, let's try that again.

Which bowl has less cubes in it? Excellent, the dark orange one has less cubes.

You're doing very good at this.

Now, let's sit and work this out.

Which bowl has less cubes in it? Which bowl has less cubes in it? Great everyone, the light orange bowl has less cubes in it.

A little bit tricky this time 'cause we had two different colours, but great counting everybody.

You're doing very well.

Give yourselves a pat on the back, excellent.

Now, I'm going to hold up some shapes.

Let's see if you know what they're called.

Shout the answers out quickly as I hold them up.

Are you ready? Name the shape, great.

Excellent, keep going.

Well done.

Great, let's do those again.

Circle, square, triangle and a rectangle.

Well done everybody.

Give yourselves two claps.

Now, here's something a little bit trickier.

I've got some lovely 2D shapes and I have some 3D shapes that I found at home.

Here, let's look at the 3D shapes.

Can you name the 3D shape? What is it? Is it a cone or a cylinder? What's the 3D shape called? Shout your answer out to the screen.

Great, it's a cylinder.

Well done everyone.

Here we are.

I've got another 3D shape here.

Can you name what it is? What's the name of the 3D shape? Is it a cuboid or a sphere? Shout your answer out.

Great, it's a sphere.

Well done, here's my final 3D shape.

Do you know what it is? Shout the answer out if you do.

Great, it's a cone.

Well done everybody.

You're doing a great job.

Now, let's have a look at some more shapes.

We're going to do some doubling now.

I think you're going to be great at this.

So, here we are.

Can you count the number of circles you can see in the shape? Let's do it together.

What is double three? Shout your answer out to the screen when you know.

Great, I can hear some of you shouting out the answer.

Let's find out, double three is six.

Well done everyone.

Let's try that again with a different number.

So, here we are.

We've got two circles in my shape now.

What is double two? Shout your answer out to the screen if you know.

Great, I can hear some of you shouting out the answer.

Let's have a look, double two is four.

Well done everybody.

And our last one, are you ready? Keep going.

We've got four here.

One, two, three, four, what is double four? Shout the answer out to the screen if you know.
