Let's Do Maths!

'Say hello to Ambrose the apprentice,

'wrestling with maths in his new job at the Grecian Pizza Parlour.'

Perimeter, outside. Area, inside.

'Meet the Measure family, using maths in fun and familiar ways

'to help with life at home.'

'And hang out with the Ugly Sisters and Buttons in the Panto House.'

'Only maths can make sense of the silly scrapes they get into.'

Me machine's on the blink!

'These videos are lesson starters for teachers of Key Stage 2 Maths.

'They explore space, shape and measure.

'And each ends with three questions,

'increasing in levels of difficulty.'

'Ambrose has just got a job at the world-famous Grecian Pizza Parlour.

'He's being trained in all aspects of pizza making.

'I don't think this is part of the training, though.'

Ahem! What are you doing?

Er, nothing.

'The boss says he's going to pop out, so Ambrose should carry on cleaning until he gets back.'

PHONE RINGS Answer the phone, Ambrose.

It could be customer. Answer the phone.

Hello, Grecian Pizza.

Can I have five Pepperoni Sun God pizzas?

'It is a customer.'

Five Pepperoni Sun God pizzas.

When will you pick them up?

-20 minutes.

-20 minutes.

20 minutes.

-OK, thank you.

-Bye.

I have to go out, Ambrose. You will have to do this yourself. Here.

'Ambrose hasn't been taught how to make a Pepperoni Sun God yet.

'The recipe is in this book.'

Inside, the recipe for the Pepperoni Sun God.

'His boss explains the most important things about this pizza

'are the cheese radius that go out from the middle like rays of the sun.'

OK, I'll get some dough, I'll show you. You take the dough,

you get a bit of flour, you put it down there like this.

'His boss shows Ambrose how to make a perfect circle out of dough.

'Good, isn't he?'

You spread the secret recipe tomato ketchup.

'He spreads the tomato sauce over the area.

'Then he estimates where the middle of the circle is.'

And then we put the column in the middle.

So we now know where the middle is.

And then you take the cheese, OK?

And put this from the middle to the edge.

You see? You take this, you put it from the middle to the edge.

The radius.

The radius is from the middle to the edge.

-What's the radius?

-From the centre to the edge, I just told you this!

From the centre to the edge is the radius.

From the edge to the edge all the way across is the diameter.

It's simples! Look, you do this, I've got to go out.

Five pizza! Remember! Good boy.

'Will Ambrose remember what a radius is?

'Can you remember what a radius is?'

'Ambrose is an apprentice pizza maker

'at the world-famous Grecian Pizza Parlour.

'He's taking his new job very seriously.

'He's even come in early today, before the pizza parlour is open.

'It looks like he's making something. Can you tell us what you're doing?'

Yeah. I've been working on some new ideas at home

and I've come in today to try one out.

I've got an idea for a new pizza. Here, have a look.

-It's going to be fantastic.

-'Can you tell us what's in it?'

No, no, no, it's a surprise. I want it to be a surprise.

But it is going to be brilliant and I think the boss might even put it on the menu.

-So, yeah, I'll... Thanks.

-'Off he goes.

'He begins with a classic tomato sauce base. Nicely spread there!'

Pepperoni!

'Now pointy pieces of pepperoni.

'Look how neatly he's laying them down.

'But he's only putting pepperoni on part of the pizza.

'Look at that. He's made a right angle. This is clever.'

Asparagus.

'Asparagus! Now, this is very interesting.

'And it looks as if he's going for another angle with those nice straight spears.

'What else is he going to use? Cherry tomatoes.'

-Mm.

-'And blueberries?

'He's done exactly half the pizza so far

'and he's made exactly the same angle as he did with the asparagus slice.

'Baby sweetcorn now. What a doozy!

'And that's an acute angle of 30 degrees.

'And he's painting it with a coffee glaze. Ooh, a nice touch.

'What's he going to put on next?

'We've come to expect the unexpected from this young man.

'Huh. I didn't expect that, though.

'Hm. Or that.

'He's either a madman or a genius! It's a fine line.

'Into the oven it goes. Now he just has to wait.

-'I bet those angles are going to taste amazing!'

-Phew!

'Look at the pizza.'

'Ambrose is an apprentice at the world-famous Grecian Pizza Parlour.

'He's learning all aspects of the profession and is now able to roll out a perfect circle of dough.

'This is how professional pizza makers make their pizza bases.

'They throw them in the air like that.

'And the dough gradually stretches out to become perfectly thin and round.

'Not quite like that.'

Ambrose, my boy, don't worry. It take me years to perfect

the perfect pizza circle.

'Luckily, Ambrose has got a nice boss.'

PHONE RINGS

Hello, Grecian Pizza.

'The customer is a maths teacher who's having a birthday party.

'He's ordering pizzas for his guests but he wants something quite unusual.'

I'd like to order 50 pizzas, please!

-50 pizzas?

-But I don't want round ones. Too boring.

I want equilateral triangles.

Equal-what-ily...twangles? What?

Equilateral triangles!

It's a triangle where all three sides are the same length

and all the angles are the same size, too.

So whichever way you look at it, it always looks the same!

Oh, and I want triangular toppings as well, please. 50 of them.

-Cheers, mate!

-Bye.

It's impossible! I spend my whole life making round pizza.

Triangular pizza? Not possible.

-I think I can do it.

-You're the man for me, Ambrose. You go ahead.

'First Ambrose makes an equilateral triangle out of dough.

'An equilateral triangle is one in which the three sides are equal

'and all the angles are equal, too.

'Then he cuts little equilateral triangles out of food.

'He's getting the hang of this, isn't he?

'Triangles are lots of fun to play around with.

'Look at all the patterns he's making.

'That looks like tessellation to me.

'What does it look like cooked?

-'Nice!'

-Oh, Ambrose, this is incredible! The triangular pizza!

Equilateral triangular pizza!

Next time, I get you to make dodecahedron.

'Today Ambrose the apprentice at the Grecian Pizza Parlour

'has been given a new job - pizza delivery boy.

'He has to deliver nice hot pizzas to four addresses. Oh, here's the boss.'

Ambrose, I want you to fill in the timetable

because I want you to do this very quickly.

The journey time, you fill in all the times, yes?

When you get to the place, write down...

'Ambrose has to write down the arrival time at each address

-'and how long each bit of the journey takes him.'

-Yes? Good boy.

'The pizza parlour clock says it's quarter past four in the afternoon

'but his boss gives Ambrose his mobile phone which has a 24-hour clock.

'The time on the phone says 16:15,

'which is the same as quarter past four.'

Don't forget to fill in the timetable.

'Ambrose goes as fast as he can to the first delivery address,

'Dave's Motors on Calculator Crescent.'

-Who ordered the pizza?

-That's me.

-There you go.

-Thank you.

-Enjoy!

16:21.

So I left the pizza parlour at 16:15, it's 16:21.

15, 16, 17, 18, 19, 20.

That's six minutes. Six.

'It then takes him ten minutes to get to the flats on Rhombus Road.

'He looks at the time...

'..works out how long it took him and writes down the time on his timetable.'

Hexagon Hill!

'It takes 15 minutes to get to Hexagon Hill.

There you go! Thank you.

'Ambrose is really up against the clock now. No time to write anything down but the time.'

-HE GASPS

-Got to go!

Pizzas are getting cold.

'He still has to get to Perimeter Place. It's 11 minutes away.

'Will he get there while the pizza is still hot?

'Will he be able to fill out the missing bits on his timetable?'

Using the 24-hour clock...

'Ambrose is an apprentice at the world-famous Grecian Pizza Parlour.

'Today he's decorating the upstairs restaurant for a sweet 16 party.

'It looks good, doesn't it?

'Ambrose's boss is bringing a heavy box up from the basement.

'It's part of his plan for how to make teenagers have a smashing time.'

This is my secret weapon.

To make the party go with a swing-a-ding-ding,

first of all, they eat the pizza.

Then we dance a little dance.

Dance the dance.

GREEK MUSIC

And then we smash the plate.

'Cool! Ambrose thinks teenagers will love that.'

I want everyone to have a smashing good time

so put the plates three deep around the perimeter.

'Ambrose's boss wants him to lay out the plates in piles of three

'all around the perimeter of the room.'

-What's the perimeter?

-The perimeter is the outside of the shape, like the room.

The area is the inside.

Perimeter, outside. Area, inside.

Perimeter, outside. Area, inside.

Perimeter, outside. Area, inside.

-You got that?

-I've got that.

-Good boy! You're on your own.

Perimeter, outside. Area, inside.

'Ambrose knows now. The perimeter is the line around the outside.

'The area is all of the inside.'

HE GROANS

'Wow, those boxes are heavy.

'He doesn't want to have to lug too many of them up the stairs.

'What you thinking?'

I'm thinking I might have to use some maths here.

How do you work out a perimeter?

'To find the perimeter of a rectangular room,

'you need to measure the length and double it,

'then measure the width and double that and add the answers together.'

Hey, I might be able to work that out.

And I'm going to use plates.

'Ambrose is measuring the restaurant in plates.

'He measures one side by counting how many plates long it is.'

30.

'The restaurant length is 30 plates long.

'Now he does the same on another side.

'And the restaurant is 20 plates wide.

'Once Ambrose has worked out the perimeter

'and how many plates he'll need to go round it three deep,

'he can work out how many boxes to bring up.

'But it's quite tricky maths.'

I need help.

'Meet Ambrose.

'He's an apprentice at the Grecian Pizza Parlour.

'The boss here is famous the world over for his pizza-making skills.

'He invented the Pepperoni Sun God and the Calamari Colossus

'and the Minotaur Munch!

'Today he's going to show Ambrose something that every young apprentice must learn.

'The secret of how to make lots of pizza bases from a two-kilo lump of dough.'

Out of this two kilos, we make 20 smaller pizza, like this.

It's beautiful, like my children. You do this.

20... Write this down.

20 small pizza from the two kilo.

'Ambrose's job today is to make 20 small pizza bases that are all the same.'

Come on, then, get on! Mush!

'Let's see how he gets on.

'Hm.

'How are you feeling about this, Ambrose?'

All right. It's going really well, thank you. I'm really pleased.

-'I think all your pizza bases are meant to be exactly the same.'

-Yeah, 20. Yeah.

-'Do you think you'll get 20 out of that?'

-Er, yeah. Yeah, yeah, yeah.

'Ambrose is meant to be making 20 small pizza bases.

'He doesn't seem to be doing a very efficient job, does he?

-'Ambrose, don't you think you should use your weigh scales?'

-What for?

'If he doesn't get this right, all the pizzas will be different sizes, won't they?

'What can you do?'

'Meet the Measure family, Mum, Ethan, Abi and Dad.

'Dad's on breakfast duty this morning and he's making pancakes.

'His pancake recipe is for four people,

'which gives all the Measures one nice big pancake each.'

-Who's for the first one?

-Me, me, me!

-Oh, yes! Come on, quick, quick.

-Me, me, me!

-Fantastic.

-Mind yourself.

-Look at this.

-Ta-da!

-Oh, look at that!

'Mm. I like pancakes, don't you?

-'The Measures like theirs with lots of maple syrup.'

-Delicious.

-'Dad can't make them quick enough.'

-Come on!

'He's showing off now. One for Abi.'

-Maple syrup, please!

-'One for Mum.'

-Thank you, darling.

'They don't last long, do they?

DOORBELL RINGS I'll get it, I'll get it.

'Oh, someone's at the door.'

-Look who it is!

-Hi!

-Hello!

-'It's Nikita and Eli.

'They can smell something delicious.'

-What are you eating?

-Pancakes. Would you like some?

-Yes, please.

-Come on in, then.

'Now they want pancakes, as well. Two each, please. And everyone else wants another one.'

-BOTH: Oh, yeah!

-Dad, stay in the kitchen. We need more pancakes.

Thanks, Dad!

'But Dad's recipe only makes four.

'Can you help him work out how to make enough pancakes for everyone?'

'Ethan Measure is a martial arts whizz kid!

'He's won so many medals, he can barely stand up!

'But there is one medal he's yet to win.

'The symmetry medal.

'It's better than all the others because it's made of chocolate.

'To win the symmetry medal, Ethan has to be able to find the line of symmetry on an object

'and karate chop it down that line.'

Hi-yah!

'Like that! Well done, Ethan.

'The line of symmetry is the imaginary line

'where if you cut something in half

'then hold either half up to a mirror,

'the object will appear whole again.

'Some lines of symmetry are easier to spot than others.

'Let's see if he's found it on this pineapple.

'Back luck, mate. Too spiky. Try again.

'Has he got it right this time?

'Yes, that looks like a pineapple.

'Ethan's mum has prepared a selection of things for him to practise on.

'Some of these have more than one line of symmetry and some have none at all.

'Can you help him find the line every time

'and win that golden chocolate medal?

'Ethan has to find the lines of symmetry in a number of objects.'

'It's a Sunday afternoon and the Measures are playing a family game.

'It's called the origami challenge.

'It's very simple. Everyone draws a shape to fold out of paper

'and then they put all the suggestions in a hat.'

OK, has everybody put theirs in the hat?

-Here we go. Drum roll, please.

-THEY TAP ON TABLE

A regular pentagon? Who put that in there?

Yes!

'The task is to fold a regular pentagon. Quite a tricky shape.'

Here we go. Dad, start the timer.

-OK, losers.

-'And they're off.'

'They've got two minutes.

'The word "penta" comes from the Ancient Greek language and means five.

'Pentagon means five angles.

'A regular pentagon is a polygon with five equal sides

'and five equal angles.

'You can find the pentagon shape all over the natural world.

'And in man-made objects, too.

'How are they doing?'

-And I am finished.

-ALL: Ohh!

-TIMER RINGS

-'Time's up.'

-Well done, Abi.

'Let's have a look at who's got it right.

'Ethan's has only got four sides, so he's disqualified.

-'What about Mum?'

-One, two, three, four, five, six! No, OK, that's no good.

'Dad's got five sides, but it's an irregular pentagon.

'Abi's is the best. Let's see how she did it.

'Abi is using a sheet of A4 paper.

'She folds the bottom corner up to the opposite corner and smoothes it.

'She's done that to make a crease.

'Now she unfolds that and folds one half in

'and lines it up with the centre crease and smoothes it.

'Now she does the same on the other side.

'And there we are, a regular pentagon.'

'Abi Measure loves to play the guitar,

'but her old one won't keep in tune.

'She's had it since she was little.

'One day, she sees the guitar of her dreams.

'A Clapton Uber-Pluck.

'Pretty cool!

'If only she had that guitar, she could play like a rock goddess!'

ROCK MUSIC

'The only problem is, a Clapton Uber-Pluck costs £300.

'Time to raid the piggy bank.

'But Abi has never been that good at saving.

'That's not enough to buy a plectrum, let alone that guitar.'

Mum!

What's the matter, love? Ooh, look at that! Gorgeous, isn't it?

-I bet you want one of those, don't you?

-Mm-hm.

-Fantastic.

-What, you're asking me for it?

-Please?

-£300?

-I'll pay you back.

You'll pay me back? Hang on, I've got a good idea.

You can do some chores around the house. There you go.

And I'll go and have a nice cup of tea.

There you go, love.

'For the next few months, Abi is a very busy girl.

'Once a week she vacuums the landing and stairs.

'For that she gets paid £1.50.

-'For cleaning the bathroom once a week...'

-Money, please!

-'..she gets £2.'

-One pound, two pounds.

-Thank you.

'She gets £1.50 a week for cleaning out the guinea pig,

'the gerbils and the hamster.

'Add to this her £4 a week pocket money...

'..and £6 a week from a neighbour for babysitting.

'Abi saves every penny she gets.

'Her brother Ethan puts an armed guard around her room.

'You can never be too sure when there are robbers about.

'One day, Abi can wait no longer.

'It's time to count the money and she thinks she's got enough.

'Look at all that cash.

'Can you help her figure out if she's got enough to buy that guitar?

'Abi earned £1.50 for vacuuming the stairs,

'£2 for cleaning the bathroom,

'£1.50 for cleaning out the pets,

'£4 pocket money and £6 for babysitting.

'Abi saved 193 £1 coins,

'nine £5 notes,

'88 50 pence pieces,

'and a jar of 20p coins.

'Abi weighs the 20 pence coins and they come to 0.855 kilograms.

'Mr Measure is meant to be clearing out all his old toys for the school jumble sale,

'but he's having a trip down memory lane instead.

'He used to love that book.

'Oh, what's this?

'Many years ago, Dad made a time capsule

'and filled it full of treasures.

'He put in all kinds of precious things, like money, and said goodbye to his favourite toys.

'And then he buried it in the woods.

'He made a map so that one day, when he was older, he could find it again.

'But for 30 years, that map has been lost.

'Now he's found it. The directions he needs to find his lost treasures.

'Before you can say time capsule, he's off to the woods.

'Mr Measure's brought along everything he needs.

'A spade, a tape measure, a metal detector

'and his son Ethan with his trusty compass.

'The map says to start at the old climbing tree

'and walk north for ten metres.

'It's Ethan's job to find north on the compass.

'That's it.

'So Dad walks north for ten metres.

'Stop!'

Ten metres. OK.

'He's winding him in like a fish.

'Next go east for 12 metres.

'Ethan knows that the needle on a compass always points to the north.

'He's lined up the needle with N.

'And from there, they work out where east is.

'Can you see it?'

Never...eat...

..Shredded...Wheat. East!

'Never Eat Shredded Wheat, NESW,

'is a good way of remembering the four points of the compass in the right order.

'And, of course, you can eat Shredded Wheat.

'Next they have to walk to the southeast for nine metres.

'This is halfway between south and east.

'Then north for 23 metres.

'Stop!

'The final instruction is go west for four metres.

'That's it, they've found the tree.'

Riches, here we come!

'It's wash day at Panto House.

'Looks like Buttons has been doing the Ugly Sisters' washing for them.

'Large, soggy undies. Ooh, poor Buttons.

'Angular and Graphica are too busy watching MasterCook to help.

'Time for Buttons to peg out the washing to dry.

'Going well so far.

'Oops!

'Looks like that line might break. What are you going to do now?

'Maximum weight 2,000 grams.

'That means there's a limit to how much you can hang up.

'And some scales.

'The scales are there to weigh the washing, Buttons.

'So you'll have to weigh some bloomers.

'Let's see how heavy the Ugly Sisters' undies are.

'Each bloomer weighs 250 grams.

'How many bloomers have you got? One, two, three, four...

'..five, six, seven,

'eight, nine, ten.

'Ten bloomers.

'Oh, and what's that at the bottom?

'Oh! It's the Ugly Sisters' extra-thick tights to stop the leg hairs from peeping out.

'You'll have to weigh those, too.

'Those tights are heavy. They weigh 315 grams.

'The line only takes 2,000 grams. I don't think you can hang everything up.

'Oh, dear. Looks like Buttons is a bit stuck.

'Let's see if we can help him put the washing out.

'It's morning at the Panto House

'and Angular, the Ugly Sister, is waiting for the post.

'She's been waiting like this for a week. I wonder why.

'Oh, what's this? A royal scroll?'

Oh, by heck!

'So this is what all the fuss is about.

'Prince Charming and Cinderella have invited the Ugly Sisters

'to their Christmas Eve ball. It's on the 24th December.

Wait till he gets a load of this!

'December is ages away! It's only June now.

'Graphica has bought a packet of magic seeds for this very occasion.

'It's a grow your own pumpkin carriage.

'From seed to carriage in just six months.

'That's a very big seed. She's planting it straight away.

'Ooh, that's fast.'

-I've never seen one like that before.

-Nor grown quick as that.

'Today's date is the 6th June.

'And it's got to be ready by the 24th December.

'I wonder if she's given it enough time.

'What's this? Angular has got some magic seeds, too.

'A grow your own Prince Charming?

'From seed to Prince Charming in just 14 weeks.

'It's the 6th June now and the ball is on the 24th December.

'Angular can't work out when to plant it, er, him.

'Can you help her work it out?'

Oh, help! Help! Buttons! I don't know.

'Puss in Boots has arrived unannounced at Panto House.

'The Ugly Sisters are not impressed.

'Puss has been lounging on the sofa eating sugar mice.

'And to make things worse, his boots stink.

'Really stink.'

Oh, you bad, bad, bad pussycat!

You should be ashamed of yourself!

'Oh, nothing's working. They need a cunning plan.'

We'll get that moggy's boots.

'The sisters mean business.

'Those boots stink worse than the acting.

'There are six unusual washing options.

'It's on the maximum setting. The red one.

-'That should do the job.'

-That should do the job.

Oh! What's that? Oh!

Graphica! Me machine's on the blink!

'That super-stinky wash has sent the machine into overdrive.'

Oh, spring meadow!

'Well, the boots may be clean...

'..but the dial is stuck.'

'Look at the dial.'

'The Ugly Sisters, Graphica and Angular,

'are very busy catching up on a bit of culture.

'Too busy to help Buttons who's been tidying up Panto House all morning.

'Now he's looking forward to a nice cup of tea

'and a fondant fancy or two.

'But the Ugly Sisters have left him a to-do list.

'Oh! Oh, dear.

'Oh, dear!

'What a pile of dirty mugs and plates.

'They've filled up the sink!

'Oh, it's going to take him ages.'

-KNOCK AT DOOR

-'Someone's at the door.'

Jack and Jill!

-'Oh, it's Jack and Jill from up the hill!'

-How are you?

-Oh, very well.

'Jill loves Buttons.

'She thinks he looks like Superman, but shorter.

'Jack thinks this is really uncool.

-'Sisters are so embarrassing.'

-So embarrassing!

-And what can I do for you?

-'Jack and Jill can't be bothered to go up the hill,

-'so they want Buttons to fill a pail with water.'

-I suppose so.

'But Buttons has a problem.

-'The sink's too full.'

-It won't fit.

-'Jill's got an idea.'

-Use the jug, Buttons.

-Don't use the jug.

'But Jack disagrees.'

-Use the bottle!

-Ignore him.

-Oh, the bottle.

'Buttons has another idea.'

-Use the bottle.

-Ignore him, use the jug.

-Bottle!

'Buttons just wants to fill the pail so he can have his tea and cake.

'Can you help Buttons fill the bucket up with water?'

What's with him?

'The pail holds 7.5 litres.

'The mug holds 500 millilitres.

'There's a one litre jug,

'a two litre bottle, and a 500 millilitre mug.

'Here's a clue.'

HE HUMS "HAPPY BIRTHDAY TO YOU"

'How exciting! Looks like it's somebody's birthday today.

'Graphica, the Ugly Sister, has made a great big cupcake.

'Oooh! That's a lot of candles.

'Oh! It's Erica the Puppet's birthday today.

'The birthday cake must be for her.

'Surely she can't be 40 years old, she's just a kid.'

-You're not 40 years old, are you? No.

-'40 months old?

'So Erica has a birthday cake every month?

'That's just an excuse for Graphica to eat a lot of cake.

'Here's the other Ugly Sister, Angular,

'with what looks like another birthday cake.

'Has Erica got two birthday cakes?

'Obviously not. What's Angular up to?

'Ah. She's made a cake for an aubergine?'

Guess whose birthday it is today!

'And another 40th?'

-Happy birthday!

-'Weeks!

'So you must be 40 weeks old.

'So Mrs Aubergine must have a birthday cake every week!

'That's an awful lot of cake Angular's got to eat.

'And she's going to need an awful lot of candles, too.

'Hm. Where's that huge pile of candles gone?

'Oh, looks like Graphica has used them all up.

'Uh-oh!

'What a lot of mess!

'What a lot of birthdays. Let's see if we can sort this lot out.

'The Ugly Sisters are giving their mouths

'a lot of exercise this morning in Panto House.

'They're munching on piles of cakes. But it's making them fat and spotty.

'They love eating cake whilst watching the telly,

'but Buttons keeps getting in their way.'

Buttons, what you doing, you silly monkey? Go on!

'Buttons doesn't think this exercise routine is working.

'He's the only one getting exercise, cleaning up all their mess.

'Buttons is tidying up all the toys they've stolen from young children at last year's panto show.

'Oh, a TV remote. I wonder if it works.

'Hm.

'I don't think it's working the telly.

'Now Buttons has a way of getting his own way back!

'Time to get some exercise.

'Off they go!

'Buttons makes them turn right out of the door

'and travel along the road.

'He wants them to go a bit faster.

'Ah, fast-forward should do it.

'He makes them walk for 30 metres.

'Then Buttons presses right.

'He makes them go along for 45 metres.

'Then he presses right again.

'They go down this road for 80 metres.

'Then he makes them go right again.

'They're definitely getting exercise now.

'Oh, no. Buttons has lost them.

'They've gone down this road for 20 metres.

'He needs three more instructions to get them home. Can you help him?

'Look at the map. This is the route

'the Ugly Sisters have walked.'
