# Lesson video

In progress...

Hello everyone.

My name's Miss Brinkwell.

I'm going to be going through this maths lesson with you today all about your three times table.

So if we look at our learning objective, what we're doing today is we're recalling our three times table.

So we're going to look at lots of different ways of representing and remembering all those numbers which are in our three times tables today.

So if you look at the lesson agenda, we're going to look at skip counting first, that's probably something that you've had some experience of.

You might not have called it that, but I'm sure you will have done it in the past, so that'll be a little bit of revision for you.

We're then going to talk about some key vocabulary for this lesson, which is products and multiples.

Don't worry if they don't mean anything to you at the moment, they will by the end of the lesson.

And then we're going to talk about how we can match pictures and calculations, so different ways of representing these multiplications.

And then you'll have a chance for some more of that in your independent work.

And then the exit quiz right at the end of the lesson.

Okay.

So all you'll need for today's lesson is a pen or pencil and some paper.

It would be really useful to have some paper, because if we were in class, we would be using number beads and things like that.

So if you can have a piece of paper to draw out those like I have been doing that would be really useful.

And just make sure you've got a really good attitude, 'cause we're going to have a fantastic lesson on our three times tables.

So pause the video and get what you need.

Okay, let's get started then.

So as a little bit of a warm-up, like I say, if we were in lesson, we would have some things that we would be moving around to represent our three times table.

I've been drawing mine out and I've drawn them out on the board here for you as well for you to have a look at.

What can you see? What do you think is being represented in this picture? Okay, wonderful.

Well, there might be different things being represented here.

I can see that we've got three beads in a row and then a small gap and then another three beads in a row.

So we could be talking about three plus three, three and then three.

Or we might be talking about two lots of three.

I've got two groups and in each group I've got three.

So it could be that this represents two times three.

It could work in the other way as well.

I could talk about having three, two groups of three and that could be switched around so it's three of two.

Any of those could be being represented here on this bead string.

But what do you think comes next? If you've had the chance to draw them out like I have, I've got my three and then my three, so I've got six.

If you draw out three more, another group of three, what's going to come next in our three times table? I've now got one, two, three, three groups of three.

So what do you think the next number on my three times table is? That's a bit clearer for you there.

Three groups and in each group I've got three.

Or for our times tables, three times three.

Three groups.

And in each group, there is three.

Three times three is nine.

I've made a mistake on the slide there, it shouldn't say six at all.

It should say nine, three times three is nine.

Okay.

What do you think comes next then? So we've got nine.

We've got our three lots of three.

Have a go on your piece of paper at drawing another group of three.

One, two, three.

How many have we got now? Now we've got four groups of three.

Four groups of three.

So how are we going to show that? Four groups of three is 12.

Now you can see on the bead string there that a couple of the numbers have changed colour.

And that's because we're getting into those double figures.

We've moved from single figures into double figures.

Okay, what comes next then? So we've got our four groups there, but what comes next? What about five lots of three, five groups of three? You can draw them if you need to, or you can add three on to 12, 'cause that's where we got to last time.

So we could do it like this, three add three add three add three add three, five lots of three is 15, much quicker to write it out like three times five is 15 or five times three is 15, they're exactly the same calculation.

Hopefully you can see from this slide why we stopped with repeated addition, that calculation at the top with all the threes, add three add three add three, that's repeated addition.

Multiplication and repeated addition are the same thing, but you can see that multiplication is a much quicker way of writing it.

So we're doing the same thing really, we've got five lots of three, but we can write it and we can work it out much more quickly if we see it as multiplication.

Okay.

If we carry on our three times table, what do you think comes next? We got to five times three is 15.

What do you think six times three is going to be? We can add another three onto 15, can't we? 15, 16, 17, 18, six times three is 18.

Here's the rest of your three times table.

I'll give you a few, we got to 18, 19, 20, 21.

So seven times three is 21.

Now let's do eight times three together, 21 add three, 22, 23, 24.

Pause the video here and have a go at telling me what the rest of the three times table is up to 12 times three.

Okay, how did you get on? Well, let's have a look.

We got to 24 for eight times three, nine times three, 25, 26, 27.

And remember that if you feel quite confident with other times tables, that you might know your nine times tables quite well, at least up to three times nine, because that's only right at the beginning of your nine times table, then if you know three times nine, you know nine times three.

So if you know your nine times table and you can go nine, 18, 27, then you can use that to help you with your three times tables.

10 times three, again, you probably know your 10 times table quite well.

Three times 10 is 30, so 10 times three is 30.

The 11 times table is one that people tend to feel quite confident with.

And 11 times three is 33, well done if you got that, and then we just need to add another three onto there for our 12 times table.

We know that three add three is six, so 33 add three is 36.

So there's the top end of our three times table.

Those are the calculations that people tend to find a little bit trickier, so it might be a good idea at this point to pause, maybe write those calculations down and think carefully about the ones that you know, maybe you feel really confident with 10 times three and 11 times three, for example, and maybe write out three or four times the ones that you're not quite so confident with like seven times three or eight times three, nine times three maybe, 12 times three.

These are the ones that it might be worth just practising a little bit.

Okay.

Let's have a look then at what we mean when we're talking about product.

Now the product is the result of multiplying.

So when we've multiplied two numbers together, the number that we end up with is our product and product is something, is a word that people use when they create something.

That's how I remember what product means.

Product is when you've created something.

So the product, when we're talking about multiplying, is what has been made.

So for example, looking at these different multiplication questions here, looking at that first one, eight times three, what has been made, the result of that multiplication is 24.

Looking at the one underneath, it's in a slightly different order in that we've got the whole first and then the equals sign, but still, what has been made is 30.

10 times three is the same as 30.

Pause the video here and think about circling the other products in those calculations.

Okay, let's see how you got on.

So not too tricky here.

Four times three is 12, that's the product.

Two times three is six, that's the product.

Three, one times three is three.

That's actually, believe it or not, a calculation that people often make a mistake on.

If you've just got one lot of three, you've got three.

So that's an important one sometimes to spend some time looking at.

And three times seven is 21.

Well done if you were able to circle all those products.

Okay, looking at multiples then.

The multiple is the result of multiplying one number by another.

So circle the multiples of three.

So what we're talking about here is the numbers that appear in the three times table.

So I know, for example, that three appears in the three times table.

Pause the video here and think about the other numbers there that do appear in the three times table.

Well done, let's have a look.

A good way of thinking about it is the ones that you're sure aren't in the three times table, those ones that shouldn't be circled.

So if we look at the ones that are in the three times table, and then the ones that aren't.

11 can't be in the three times table because 12 is, so there can't be a difference of three between 11 and 12, we know there's only a difference of one.

Five, again, six is in the three times tables, so five can't be.

And 10, we know that 10 is a multiple of two it's a multiple of five, but it's not in the three times table.

So well done if you got all of those right.

Okay, let's have a look at this representation of the three times table then.

What can you see here? How could you describe what you can see? Well, we can see five nests and in each nest there are three eggs.

Let's just check, one, two, three, four, five, and they're all identical.

They've all got the same number of eggs in them.

So each group has three in and I've got five groups.

I've got five groups of three, five times three.

Can you remember what five times three is? Remember that you can do three times five if you prefer, so you can go five, 10, 15, or if you're going in your three times table, three, six, nine, 12, 15.

Five times three is 15.

Okay, you're turn then.

Pause the video and have a look at this picture.

I've given you a little bit of help there on the side as well.

Okay, so in those pictures, hopefully you can see that we've got groups of three people sat around tables and there are four tables, four tables of three, four groups of three people.

So the question here is four times three, four times three, four lots of three, three, six, nine, 12.

Well done if you got that one right.

Okay, time to pause the video and have a go at some really similar questions on your own.

Come back for the answers whenever you need to.

Okay, let's see how you got on.

So these are questions where you have been given the pictures to help you.

And so you can link the question with the picture and then have a go at answering them or in the other order if you'd prefer, completely up to you.

So two times by three, the answer is six, two lots of three, three six.

The answer, the figure, which the number, which is the same as 10 times three is equal to 10 times three is 30.

Nine times three is 27 and seven times three is 21.

Really, really well done if you got all of those right, you're starting to feel really confident with your three times tables, that's fantastic.

And here's how they link up to those lovely pictures of people with stickers and jars of biscuits and things.

Okay, here you just need to fill in the gaps on your three times tables.

So a nice little practise about where these numbers fit on your three times table.

Hopefully you know that if we've got the answer three, that must mean one times three.

Two times three is six and three times three is nine.

It's four times three that's 12 and five times three is 15.

Well done.

Another little practise here with the arrows as the first part of your three times table.

So it goes three, six, nine, 12, 15.

Really well done if you were able to get all of those right.

And for the last question, spot the odd one out.

Well, hopefully you've become really confident in identifying multiples of three.

And you can see which one of these is not a multiple of three.

It shouldn't actually be 21.

21 is in the three times timetable.

The circle should be around the 13.

13 is the correct odd one out there.

13 is not in the three times table.

Just made a little mistake there.

Okay, and now it's time to complete the quiz and see how well you got on with today's learning.

Well done everybody, enjoy the rest of your day.

Bye bye.
