# Lesson video

In progress...

Hello everyone, I'm Miss Brinkworth.

I'm going to be going through this maths lesson with you today, which is all about your four times table.

So if we have a look at our learning objective.

What we're doing today is recalling our four times table.

Our four times table is a really, really important one.

This is because if you can become very fluent with it very confident, that means that you don't have to count it out on your fingers or think too long in your head before finding the answer.

So if we can have a really successful lesson and feel really confident with our four times table it's going to help us with lots and lots of questions we might come across.

So, let's get started.

So, for today's lesson your agenda is that we are skip counting to begin with.

So this means, this might be the normal way that you're used to practising your times tables.

And that's how we're going to start today.

You might not call it skip counting but it's where we sort of add on each time.

And that's how we're going to start the lesson for today.

Going through our four times table in a lot of depth and talking about how we can remember each of the facts, then we're going to move onto some key vocabulary which is about products and multiples.

You might not feel very confident with those words just at the moment, but I promise you will by the end of the lesson.

We are then going to be matching pictures and calculations.

So this is really important, especially when we talk about our multiplication is to have different ways of representing our multiplication questions.

This is to really ensure we actually understand what we mean when we're talking about multiplications.

Why do we use them? Why are they useful? What are we actually talking about? And then at the end of the lesson, there'll be that independent work that will give you a task to practise your new skills.

And then there'll be a quiz right at the end as well, where you'll get to see how many questions you can get right all about your four times table.

So for today's lesson, all you need is a pen or pencil, some paper and a really good attitude because you're going to feel really confident about your four times table by the end of the lesson.

Pause the video here if you need to and get your equipment.

Okay, should we get started on the warmup? So before we get started our four times table I thought it'd be a really good place to start with our three times table.

So I've got some three times table questions for you here.

Now, I haven't given you the easier part of the three times table, the ones down the end, the ones, twos and threes.

I've given you the top end which sometimes people struggle with a little bit.

So starting with seven and going on to 12 times three.

But if you do get stuck, you can use that lower end of the three times table to help you.

For example, if you know what four times three is you can double it to find an eight times three.

You can also use other facts that you feel quite confident with.

If you know what 10 times three is, can you adapt it to find your nine times three and your 11 times three? Pause the video here and answer those questions.

Okay, let's see how you got on then.

So for seven times three you might know five times three maybe.

People normally feel quite confident with their five times tables.

So five times three, five lots of three.

We've got three, six, nine, 12, 15.

Five times three is 15.

I then just need to add on two more threes.

So two threes are six, 15 add six.

Well, six is one more than five.

15 add five would be 20.

So 15 add six is 21.

That might not be how you think about seven times three and that's absolutely fine.

As long as you get the right answer, that's fine.

Eight times three, like I said you could double four times three.

So if you know what four times three is you can double it to find your eight times three.

So four times three is 12.

So eight times three is 24.

Nine times three, you might want to think of it as three more of eight times three or three less of 10 times three.

If you feel confident with 10 times three is 30, you could take three away from 30 to get your nine times three, which is 27, or maybe, you know your nine times tables quite confidently, and you can do nine, 18, 27 in your nine times table.

And remember that you can do multiplication in any order.

So you can use your nine times table if that's one you're happy with.

Most people feel quite confident with that 10 times table, those multiples of 10.

So three made times bigger is 30.

And then, we add three more for 11 times three.

Again, most people feel confident with their 11 times tables and 12 times three there is 36.

Let's move on to our four times table.

What can you see here? What is being represented here with this bead string? Well, it's the first three questions in your four times table.

We've got three fours shown there, three fours.

We've got four, eight, 12.

What do you notice about those numbers? What do they all have in common? Well, they are all even numbers.

That means they're all in the two times table, they can all evenly be split in two.

They are even numbers.

There are no odd numbers in the four times table.

So if you come across an odd number today, one that can't equally be split in half, you've made a mistake.

The four times table is very closely related to the two times table.

Why do you think that might be? Well, we know that four is double two.

So our four times table follows a similar pattern to our two times table.

In fact, it skips one of our twos.

That's because four is double two.

So instead of counting on two each time we're counting on four each time.

So if you feel very confident with your two times table and I'm hoping a lot of you do, you can use that today to help you answer your four times table questions.

So if we look at what's being presented here in this picture we've got those first three facts of our four times table.

There's our repeated addition that gives us 12.

If we want to write that as multiplication we've got three times four.

But we also know that multiplication can be done in any order.

So it's also four times three.

Those are our first facts about the four times table.

What number do you think is going to appear next then? What comes next after 12? What is four times four? Well, like I said, it's skips one of the two times tables.

So two would go 12, 14, 16.

The four times table skips out the 14 and goes to 16.

So here's the repeated addition again.

This time I've got four lots of four, four add four add four add four, four lots of four is 16.

But I've only got this one other bar to appear this time.

And that's because it's four times four.

So if I swap the order of that 'round I'll still have four times four.

Oh no, I've made a mistake, can you see? Four times four isn't six Miss Brinkworth.

Four times four is 16.

What do you think is going to come next? Well, you could use your number bonds to help you.

We've got six in our ones column.

I'm going to add on another four.

So we're going to get to a multiple of 10.

The next number is 20.

If you look at our repeated addition this time, we've got five lots of four.

And hopefully, you can see why we move onto multiplication rather than repeated addition.

That calculation is quite long and it's quite complicated.

It's really muddled.

It's hard to see how many different fours we've got.

And so writing that as multiplication is much shorter to write and also much quicker for us to work out.

We're much less likely to make a mistake.

Repeated addition and multiplication can show exactly the same thing but multiplication is a much simpler, more efficient way of showing that, that I've got five fours.

Some of you might feel quite confident with your five times table and want to think about that as four fives.

That's absolutely fine as well.

So now we've got to 20, we've got to a multiple of four, so five times four.

Moving on then, what number is going to appear next? We're at 20 and we're going to add four aren't we? We're going to jump on another four.

So 20 add four, for six times four is 24.

And there's the facts that we've got so far.

Hopefully you can see that they are all even numbers and that they miss out one of the two times table.

We are counting on four each time.

There are other facts that maybe you like to use.

I think about 24 and double 12.

I know that two times six is 12, four is double two, so the answer for four times six or six times four is double 12, which gives me 24.

Maybe there's some other facts that you'd like to use to remember your four times table.

Okay, here's the rest of your four times table then.

Again, like we mentioned with the three times table sometimes people find this end of the times table a little bit trickier.

So let's think if we can think of some tricks to remember them.

So the seven times four, we have 24 for six times four.

So seven times four we're going to add another four on to get to 28.

For eight times four, we need to split one of the twos.

So we're not going to go to 28, 30.

We're going to go to 32.

Remember they're all even numbers.

For nine times four, again, some people might feel quite confident with their nine times table.

They might want to think about four times nine, nine, 18, 27, 36.

Or you might just want to add four onto two, go from 32 to 36.

We then get into some questions that people normally feel quite confident about, their tens and their elevens.

So four made 10 times bigger is 40.

And four made 11 times bigger is 44.

We then just need to add one more four onto 44 to give us 48, for 12 times four.

Well done everybody.

So there is our four times table, those are all the facts that we need for today.

So we've done a lot counting on.

Now let's have a think about becoming a little bit more confident with understanding these facts as they stand on their own.

So here is one of our star words.

And it is product.

The product is the result of multiplying.

Product is often a word people use when they've created something, they made something, they've made a product.

Maybe it's some food or an item, they've got a product that they've created.

And when we talk about products and multiplication it's the result of multiplying.

So for example, the product of five and four is 20.

It doesn't matter what order I do that in, the product of four and five is also 20.

So pause the video here and have a go at finding the products in those calculations.

Shall we see how you got on? So the products of these questions, the result of multiplication.

Well done especially if you've got that last one where it's actually coming at the beginning of the calculation.

Well done if you were able to see that seven times four is the same as 28.

So that's one of our star words, product.

The other one we've got is multiple.

A multiple of four is one which is in the four times table.

So have a look at these numbers and think which ones are in the four times table.

For example, eight certainly is.

So pause the video here and see how many others you can find.

Okay.

It's good to think about the ones which are in the four times table.

It's also sometimes useful to think about ones which aren't in the four times table.

Maybe there's ones on there that you know aren't.

So they're not going to get circled.

Well done, if you could see that these ones are circled.

17 for example, is an odd number, so it can't be in the four times table.

We talked about how all numbers in the four times are even, 17 is odd.

six and 10 are even and they do appear in the two times table.

So that can be confusing sometimes.

But we know that eight is in the four times table.

And eight is only two away from both six and 10.

So those numbers just can't be in the four times table.

You can them if you need to couldn't you? Four, eight, 12, oh no, we've missed out six and 10, they're not in the four times table.

Okay, have a think about what you can see here.

We've got some jars and they've all got biscuits in.

They've all got the same number of biscuits in actually.

How many biscuits have they all got in? They've all got four biscuits in.

How many jars do I have? I've got one two, three, four, five.

So what question might this be? I've got five jars and they've each got four biscuits in them.

Five times four.

Can you remember five times four or four times five if you prefer? Shall we count in our four times table? Four, eight, 12, 16, 20.

I have got 20 biscuits in total.

Can you have a go here? These are pots of pens, and they've each got four pens in them.

What question do you think is being asked? Pause the video.

Okay, let's have a look.

What do you need to do is count how many pots of pens there are.

There are one, two, three, four, five, six.

Six times four.

Well, we just did five times four.

Could you remember what five times four was? It was 20.

So I just need to add another four onto 20 to find six times four.

So well done if you knew that six times four is 24.

And remember that I said that six times four I think of as double two times six, two times six is 12, I feel really confident with that fact as I can double it to find four times six.

Okay, pause the video here and have a go at your independent task.

Shall we see how you got on? So some nice questions here about your four times table, just to get you recapping on it.

So, two times four is eight.

The result, the product of 10 and four is 40.

Three times four is 12 and four times four is 16.

And these are the pictures that relate to those.

We've got nests, we've got tables, we've got sheep and all in the four times table.

Well done.

Again, just some questions here, just at the beginning of your four times table get you thinking about those numbers clearly.

So one times four is four and two times four is eight.

Three times four is 12 and four times four is 16, and it's five times four which is 20.

Well done if you were able to draw those arrows on, they go four, eight, 12, 16, 20.

A really clear way of showing what our times tables are all about.

Again, it jumps by four we're taking equal groups of four each time.

Okay, last question, spotting the odd one out.

Could you see which of those numbers was the odd one out? Now hopefully you remembered that this lesson was all about your four times table.

One of those numbers is not in your four times table and it is 14.

Well done if you were able to see that.

I was trying to trick you a little bit, 'cause that number does have a four in it, but it's not in the four times table.

12 is, and 16 is, but 14 is not.

Okay, really well done on today's work today everybody.

I'd love to see your work, your independent work or any of your working out that you've been doing throughout the lesson.

If you'd like to share it with us please ask a parent or carer to share your work on Instagram or Facebook or Twitter at tagging @OakNational and #LearnwithOak.

But before you go, please have a go at that final knowledge quiz and see how many questions you can get right all about your four times table.

Well done for all your hard work today everybody.

Bye-bye.
