Lesson video

Hello, I'm Mrs. Martin.

I did the last lesson when we were looking at counting in multiples of 10.

And we're going to carry that on today.

So we're going to practise counting in our multiples of 10.

Now to begin with, I just need you to have your fingers and your hands, and if there's an adult nearby, or if there's somebody else, maybe a brother or a sister, see if they will help us.

Now, last lesson we included our thumbs in with our fingers when we were counting in our groups of 10, so that we're calling these 10 fingers for today.

So in a second, I would like you to press pause on the video and I'd like you to go and talk to your adult, or it might be your friend or your brother or your sister, and ask them to flash their hands up at you like that, in groups of 10, And I would like you to count how many groups of 10 you saw.

You might say, "One group of 10, "two groups of 10, three groups of 10." Or you could use the quick way that we practised last lesson, which was by saying, "One 10, two tens, three tens." And then I would like you also to try and tell them how many fingers you saw.

So you will need to count in your tens for that.

Let's have a little practise with me? How many groups of 10 did you see? Fantastic, three tens.

I flashed my hands three times.

And how many fingers did you see altogether then? Brilliant, 30.

That's right.

So press pause on the video now and go and ask your adult if they can flash their hands, or your brother or your sister.

Super.

Super, I hope you enjoyed that little activity.

Now we're going to have a little practise at counting how many fingers there are on this screen, remember we're including our thumbs in that as one group of 10 there.

Now I would like you to press pause on the video, and I'd like you first of all, to count in your groups of 10 and then use your multiples of 10 to work out how many fingers there are.

So press pause on the video now.

Brilliant, okay.

Let's check.

How many fingers did you see? And how many groups of 10 did you see? So how many groups of 10 can you see? Seven groups of 10, lovely.

And how many fingers did you think you saw? 70, excellent.

Did you count in your multiples of 10 to work that out? Fantastic, let's have a little check together.

Let's count all together.

Ten, twenty, thirty, forty, fifty, sixty, seventy.

Excellent, there were 70 fingers all together because there are seven groups of 10.

Now, if I wanted to check that 70 was correct, I could also count backwards in my multiples of 10.

So I'm going to do that and to help me, I'm going to cross out the groups of 10, once I've counted them.

So at the moment, there are 70 fingers there.

And I'm going to count back in tens now.

So, seventy, sixty, there are 60 fingers left there, Fifty, I can see 50 fingers left all together, 50, 40, lovely counting along, thirty, twenty, 20 fingers left so far, ten, zero.

So we were right, it was 70 fingers.

Fantastic counting forwards and backwards with your multiples of 10.

We're going to practise now, counting in our multiples of 10 and look at how many pencils that are all together.

Now I know that these are in a group of 10 because I can see it says "10 pencils" there.

And if I count all the individual pencils there, there are 10.

So there are 10 pencils in each group.

Okay, just like in our last lesson.

So how many pencils are there altogether? I'd like you to press pause on the video in a second and I'd like you to count, first of all, how many groups of 10 you can see, and then count in your multiples of 10 to work at how many pencils there are altogether.

Okay, press pause.

Super, so let's check all together.

So how many groups of pencils can you see? Nine pencils, fantastic.

Now how many pencils is that altogether then? 90, excellent.

Let's check together.

Ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety, brilliant.

90 pencils all together.

Now, just like we did with the hands, if I wanted to check that and I wanted to count backwards, I could count backwards to check it, couldn't I? So how many pencils were there all together? There were 90 pencils, brilliant.

Let's start then, counting backwards.

And let's hope that we get back to zero and we'll know then that we've got the correct amount.

Ninety, eighty, seventy, sixty, fifty, forty, thirty, twenty, ten, zero, excellent.

There were zero pencils left with them when we counted backwards with our multiples of 10.

So then it must have been 90 pencils in the pack, 90 pencils on the screen altogether.

Fantastic counting in tens, then.

This time there's something a little bit different about the pencils.

What do you notice? Yep, three groups of 10 have been put in a circle.

Can you see that as three groups of 10 there? And they're all in that circle.

So this time I'm going to start from three groups of 10, because I know that there are three groups of 10 already in that circle.

And I'm going to count on from three groups of 10 to see how many groups of 10 that are all together.

Okay, can you start with me? So we're going to start from our three groups of 10, three groups of 10, four groups of 10, five groups of 10, six groups of 10, seven groups of 10, eight groups of 10, nine groups of 10, fantastic.

So if there nine groups of 10, how many pencils are there, I wonder? Well, how many pencils are there in this first little group here that have been circled, there were three groups there, weren't there? How many pencils are that all together in there? 30, excellent.

Let's just check, ten, twenty, thirty, super.

So we're going to start counting from 30 now to see how many pencils there are all together.

So join in with me and a little of that pronunciation, I could hear you really clearly saying 30, not 13.

Brilliant off we go.

Thirty, forty, fifty, sixty, seventy, eighty, ninety.

You're 90 pencils altogether.

Well done, that can be a little bit tricky, starting counting from another multiple of 10.

You did a brilliant job starting counting from 30, there, well done.

This time, can you see there are more pencils in my circles already? Look how many, there's lots this time, lots there in the circle.

So let's count how many groups of 10 are in that circle to begin with.

So we've got one group of 10, two groups of 10, three groups of 10, four groups of 10, five groups of 10, six groups of 10, seven groups of 10, eight groups of 10, have already been circled.

Eight groups of 10, okay.

So if I count on from that, if we had eight groups of 10, how many pencils are that all-- How many groups of 10, sorry, are that on the screen altogether, if I knew that there are eight groups of 10 up to here? Eight groups of 10, nine groups of 10.

Fantastic, nine groups of 10.

There's only one more group of 10 outside of the circle, isn't there? So there are nine groups of 10 on the screen.

How many pencils are there then, altogether? Well let's start by trying to work out how many pencils there are in the circle.

We're going to count in our multiples of 10.

Join in with me, ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, So there are 80 pencils in the circles, and we can see them there, they've already been put in that big circle.

So how many more pencils are there? There's these pencils that are just left out here.

So we're going to count on starting from 80, because there are 80 pencils, we got up to here counting, so they're 80 pencils here.

I'm going to carry on counting on, in our multiples of 10.

So eighty, ninety.

Brilliant, there are 90 pencils all together on the screen.

Fantastic counting on then, brilliant.

You have done some amazing counting in tens.

And now that we've learned to count in tens, we're going to learn to group into tens.

So what I need you to do is to press pause in the video in a second and get those Lego bricks that we talked about last lesson, or maybe some pasta, make sure you've asked an adult first though, or just a few little objects that you can count, and that you will be able to put into groups of 10.

I've got some little pasta shells here to help me.

So press pause on your video, now, and go and get a few objects that you will be able to count and put into groups of 10.

So you can put your objects just to one side.

We're going to use them in just a minute.

This is an awful lot of counters on my screen.

I need to try and work out how many counters there are.

I wonder how I could count how many there are.

What do you think? Should I start by trying to count in ones? Okay, let's see, one, two, three, four.

I've lost track, I don't know which counter I got up to.

Maybe, I think count in twos, we learned counting we learned counting in twos with Mrs Evers, didn't we? Okay, let me try and count in twos.

Two, four, six.

Oh, I'm starting to lose track again, there's too many dots there, too many counters.

What do you think I could count in instead to help me? I could maybe try and group them into tens because we've got so good at counting in our tens.

Let me try and see if that helps me.

Oh, ten, twenty.

That really helped me.

It helped me because there are so many counters.

When you're counting lots and lots of things, it's easier to put them into bigger groups.

If I try and put them into small groups, like groups of two, it's going to take me a really long time and I might get in a bit of a muddle, like I just did there.

So I'm going to use multiples of 10 because there's lots of objects and I want to put them in a big group, like multiples of 10.

Let me have a little go at counting these all together.

There we go, another group of 10.

So I've got three groups of 10, three tens, four tens, five tens, six tens, seven tens, eight tens, nine tens.

I had nine tens all together, I had nine tens.

How many counters would that be? Can you help me count nine multiples of 10? Ten, twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety, 90 counters.

Excellent, because I know if there are nine groups of 10, then there must be 90 counters, because nine groups of 10 equals 90.

Super-duper counting, well done.

Okay, I'd like you to get your objects that you'd put on one side, and you might have some Lego bricks, you might have some pasta, like me.

And now I'd like you to have a go at putting them into groups of 10.

Now remember, we're going to use groups of 10 because if I just do them one at a time, like that, it's going to take me ages in groups of one and I'm going to get lost.

And if I try and do groups of two, two is still too small.

It's going to take me really long time.

And when I try counting in my twos, I might get in a bit of a muddle.

So I'm going to put them into groups of 10, because I've got lots of different objects to count, lots, and to try and work out as I'm going to put them in groups of 10 at a time.

Now as you do it, you might end up with some leftover that don't fit in a group of 10, that's okay.

Just put them to one side so that all you're left with are your objects in groups of 10, okay.

Press pause on the video now and have a go at that.

Have you grouped your objects into groups of 10? So there's mine.

Now I have some left over here that didn't make a group of 10, so I'm just putting them to one side because I'm not going to use those.

So now I've got my objects all in groups of 10.

I've got five groups of 10, five tens, one 10, two tens, three tens, four tens, five tens.

And if I counted by multiples of 10, I can see I've got 10, 20, 30, 40, 50, I have 50 pieces of pasta.

How many groups of 10 have you got? And how many objects have you got altogether? Now, sometimes when we're trying to work out our groups of 10, if we're trying to count a lot of objects, we might not be able to move them.

So how can I work out how many apples there are on screen? I can't move them.

I can't put them into groups of 10, like I did with my pieces of pasta.

But I could draw around my groups of 10, so let's have a go at drawing around my groups of 10.

There's one 10, two tens, three tens, four tens, five tens, six tens, there are six tens on there.

If they're six tens, that must mean they're are.

Super, 60 apples.

Now I'd like you to have a little go with your pasta or your objects, your bricks.

But this time we've got them into our lovely groups of 10 before, didn't we? I'm just going to muddle them all back up, and I'm not going to move them this time into the groups of 10.

I'm going to draw around, and I'm going to draw around and put them into groups of 10.

So press pause on the video now and have a little go at drawing, 'round your objects and putting them into groups of 10.

Have you had to go at circling your objects, here's mine.

So I've drawn the circles 'round the object, I tried not to move them.

So this time, instead of moving them to put them in groups of 10, I circled 'round and I can still see that I have got five groups of 10.

One group of 10, two groups of 10, three groups of 10, four groups of 10, five groups of 10.

There are still five groups of 10 there, even though they looked a little bit different to when I moved them all into the groups of 10 by themselves.

Okay, fantastic.

Super drawing around your objects.

Have a little look at the screen, and I'd like you to see if you can work out what's the same and what's different between the two pictures.

So there's a picture on the left that's got the blue, the dark blue circles, and the picture on the right, which has got the turquoise circles.

What do you notice that's the same? And what do you notice that's different? Have a little think.

Okay, should we count in our groups of 10? First of all, to see if we can help work out how many apples and how many groups of 10 there are in each picture.

One 10, two tens, three tens, four tens, five tens, six tens, there's six tens there.

So if there are six tens, how many apples are that all together? Counting on multiples of tens check, ten, twenty, thirty, forty, fifty, sixty.

There were 60 apples because there are six groups of 10.

I'm just going to write 60 at the bottom to remind me so that we don't forget that there are 60, 60 apples over there.

Okay, let's now have a little look at the picture on the right and see how many groups of 10 there are to begin with.

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

Oh, six tens.

How many tens were there on the other side? That's right, there were six tens over there as well, wasn't there? So how many apples are there all together, here? How many apples are there on this side? Should we count in our multiples of 10? Ten, twenty, thirty, forty, fifty, sixty.

There are 60 apples.

Let me just write that here so I don't forget.

There are 60 apples over here.

Excuse my writing, not the best.

So there are 60 apples on the left and there were 60 apples on the right.

So there's the same number of apples on both sides.

And how many groups of 10 were over here? How many groups of 10 on the left side? Six groups of 10.

And how many groups of 10 over here, on the right? Six groups of ten.

So they both had six groups of 10.

They both have 60 apples all together.

So what's different? How they've been grouped is different.

So it doesn't matter if you group them like this, where it goes all the way up there, or it doesn't matter if you group them in more of a circle, like this.

It doesn't matter so long as there are 10 apples in each group.

So you could draw around your objects in different ways, but still have the same total.

So long as there are 10 objects in each group, it doesn't matter how you draw that, how it looks on the page, fantastic.

Number One from Number Blocks has joined us today for our maths lesson.

And there's lots and lots of Number One on our screen.

Can you help me work out how many Number Ones there are on our screen? And I would like you to trace around and see if you can put them into groups of 10 for me.

Press pause on the video now.

How many groups of 10 did you find? Three groups of 10? Excellent, three groups of 10.

Should we check and see if I get the same as you? So let me draw around.

Now, remember it doesn't matter if my groups of 10 look ever so slightly different to yours, because as long as there are 10 in each group, then it doesn't matter how that 10 is drawn.

Let's just check there's 10 there.

Then draw another group of 10.

And then the last group of 10.

Check there's 10 in there.

Fantastic, how many groups of 10 can you see? There are three groups of 10, two, three, tens.

So how many of Number One from Number Blocks have we got on our screen? Ten, twenty, thirty.

30 Number Ones from Number Blocks are on our screen.

Fantastic counting.

Last lesson I asked you at the very end of it to make some tens counters.

And I asked you to make them just like this so that they've got the little 10 frame on them, these counters.

And I know then that there are 10 dots on each counter because it's arranged like a tens frame.

So I don't need to count them like one, two, three, four, five, six, seven, eight, nine, 10.

Because I know that if it's like a tens frame and that tens frame is full, there are 10 counters there.

Okay, so just press pause on the video now, if you haven't already got your counters nearby, and go and get them for me please, thanks.

Okay, so you've got your counters next to you.

We're going to practise counting on from different multiples of 10, just like we did at beginning of the lesson with our hands and counting how many fingers there were all together and with the pencils.

So how many groups of 10 can you see on the screen? Three groups of 10, fantastic.

We can see that there are three groups of 10 there, straightaway.

So we're going to start counting from three groups of 10 and see how many groups of 10 we get.

Three groups of 10, join in with me.

Four groups of 10, five groups of 10, six groups of 10, seven groups of 10, fantastic.

We found that there were seven groups of 10.

So if there were seven groups of 10, I wonder how many dots there were all together.

How many dots am I starting with? If I look here, I can see that I've got how many dots there am I starting with, do you think? Can you count any multiples of 10? Have a go? 30, excellent.

So I'm starting from 30, count with me in our multiples of 10.

Thirty, forty, fifty, sixty, seventy, seventy.

It's 70 dots because there were seven groups of 10.

Brilliant counting, it can be really tricky sometimes to start from a different multiple of 10, rather than zero, so you did an excellent job, well done.

Now it's your turn to practise counting in multiples of 10.

I would like you to get the counters that you've got near you before and I'd like you put them in front of you.

Can you meet them exactly like they are on my screen? Can you set them out exactly the same? So on the very top row, you've got five groups of 10 there, I can see them.

One, two, three, four, five.

And then underneath there are two groups of 10.

press pause on the video and make your counters look like mine.

Okay, we're going to start counting to see how many dots there are all together.

But this time we're not going to start at 10 here, because we're going to start from these three tens that we've got in that circle.

So how many dots are there in that group, in the three groups of 10? 30, fantastic.

So press pause and count on from 30.

How many dots all together did you get? 70, fantastic.

Let's check together.

So we're starting from 30 because there are three groups of 10 already circled here.

So we're going to start from 30, forty, fifty, sixty, seventy.

Excellent.

Can you make yours look like mine again? So you shouldn't need to move your counters.

This time, we're not starting from three groups of 10, so from 30.

How many groups of 10 are in the circle this time? How many groups of 10 have been circled? Excellent, five groups of 10.

So how many dots is that? There are five groups of 10.

Brilliant, 50.

Should we just check? Ten, twenty, thirty, forty, fifty.

Now I want to know how many dots there are on the whole screen.

So we're going to start from 50.

Use your counters, press pause in the video and count on from 50 to see how many dots are are together, off you go.

How many dots did you get? 70, excellent let's check.

So we'd already decided that there were 50 dots here, hadn't we? So we're going to start from 50.

Fifty, sixty, seventy.

Excellent, there are 70 dots.

Fantastic counting, you're getting so good at this.

Okay, next one.

So you still got the dots in the same.

You still got your counters in the same arrangement, you don't need to move any of those, but this time there's not three groups of 10 in the circle, and there's not five groups of 10 in a circle.

How many groups of 10 are in the circle this time? That's right, there's six groups of 10, aren't there? I can see the six groups of 10 that have been circled here.

So there are six groups of 10 in the circle.

How many dots are there that have already been circled? 60, fantastic.

Let's just check.

Ten, twenty, thirty, forty, fifty, sixty, super.

So we're going to start from 60 this time.

Off you go, press pause.

How many dots did you get all together? 70, fantastic let's check.

So we knew that there were six groups of 10 already in the circle.

And we knew that six groups of 10 meant that there was 60 dots.

So let's start from 60, 70.

There are 70 dots on the screen, fantastic.

If I wanted to count backwards, what could I do to check, just to double check that there are 70 dots? Could I move the counters away? I can't move them off my screen, I can cross them out.

But you could count backwards and move your counters out of the way to check to see if you get back to zero.

Let's have a go at checking.

So I want you to count backwards from 70, in your multiples of 10, move a counter away each at a time.

And see if you get back to zero.

Press pause on the video.

Super, let's have a check, did it work? Let's check with mine.

So cross them out to.

How many dots did we think that we've got all together? 70, so seventy, sixty, fifty, forty, thirty, twenty, ten, zero, we were right.

There were 70 dots all together, amazing counting.

Okay, so for your practise, for your home task today, I would like you to make some cards.

And on each card, I would like you to put a multiple of 10 on them.

So you might make your cards with some paper, might put it on the back of a cereal box.

You might have some old cards, anything that you can find that you can write some multiples of 10, and make a few different cards.

And then I would like you to ask your grownup to flash their fingers at you, just like they did in that last game, the game at the very beginning of the lesson, sorry.

So you'll say to them, "Flash me some fingers," and they'll go-- And then you have to find the card that matches how many fingers they flashed.

So how many did I just do that last time? I'll do it again for you just in case.

Fantastic, 20 fingers, then.

Because there were two groups of 10, so you would get your 20 card and you'd show it to your adult or your friend.

And then you need to get them to do it again.

How many did you see? Three groups of 10, which meant there are 30, excellent.

Then you get your 30 card and you'd show that to your adult.

That's a little game that I'd like you to have a go at playing.

Then for next lesson, just like you did for me for this last lesson, and you made some counters with 10 dots on them.

This time I would like you to make 10 counters with five dots on each of them.

So by the end of this you'll have some counters with two dots on, some counters with 10 dots on, and some counters with five dots on.

Make sure you keep them safe at the end of each lesson, because we will keep coming back to using all of them.

Don't get rid of your two dot ones or your ten dot ones.

But for next lesson, I would like you to make some that have got five dots on them.

And they're arranged just like this.

Exactly like in the tens frame, again.

But it's just that one side that's full, isn't it? So one whole column that is full.

Can you make those for the next lesson? Amazing mathematics today.

You are absolutely super at counting in your multiples of 10 and grouping your objects in multiples of 10.

Well done, amazing work.
