Key Stage 2 3, 2, 1, Go!

Sports people must be fast.

Strong.

And deadly accurate.

But did you know they wouldn't be able to compete without maths?

Timekeeping.

Scoring.

Speed.

Shape.

Distance. It's all mathematics.

A tenth of a second, or just a few millimetres,

can transform an ordinary person into a world champion.

Great Britain get the gold!

This is...

-3, 2, 1..

-Go.

We take teams to a secret location.

This really is a special place!

-This is fabulous.

-To be given a behind-the-scenes tour.

THEY SQUEAL

And meet their sporting heroes.

Hiya, Jack, nice to meet you.

Who'll give them a maths challenge.

3, 2, 1, go!

-Go!

-Go!

-And if they get it right...

-17!

..2...3...4.

What does he suggest?

He should dive to the bottom right corner.

They win a gold medal.

This challenge is all about gymnastics.

Gymnastics is a sport that

involves the performance of exercises demonstrating

strength, agility and balance.

Floor exercises take place on a mat measuring 12 metres by 12 metres.

A performance must contain forward,

backwards and sideways acrobatic elements, and a balance move.

It must not exceed 70 seconds,

and they must not step outside the lines. So are you ready?

3, 2, 1, go!

-This is scary.

-I know.

Today gymnastics fans Courtney and Jack

are being taken to a secret location near Heathrow Airport

to complete their 3, 2, 1, Go! challenge.

I like gymnastics a lot. I like to do flips.

And sometimes my teacher, she puts a long rope

and you have to swing round and round. It's just really fun.

Courtney has been learning gymnastics

for three and a half years.

She is ten years old. She goes to a gym club every week.

And her favourite piece is the balance bar.

I love gymnastics because you can do really fun things sometimes.

But I can't do the splits and everything.

Jack is just learning gymnastics. He is nine years old.

He loves gym class at school. And his favourite move is the splits...

Well, when he can do it.

I want to watch gymnastics

so I can learn how to do stuff that I didn't know already.

It's mostly a girl thing, but loads of boys do it.

Yes, they do, and they're not half good at it as well!

Just you wait, Jack. So can you see where we're going, guys?

-It's the Heathrow Gymnastics Club.

-Cool!

I'm not surprised you're excited.

The Heathrow Gymnastics Club is the UK's only

official Olympic Association training gymnasium.

It is the largest gymnastics facility in England

and is the most successful British club across all disciplines.

This is where they're going to be given their 3, 2, 1, Go! challenge.

-I would love that.

-That would be amazing.

-Amazing.

Courtney and Jack can't wait to have a look around.

-Hi, Jack. Come in. Welcome to Heathrow.

-Thank you.

This is where elite British gymnasts come to train.

That's amazing! Oh, my God. That's wicked.

Now even though they've come for a maths challenge...

Imagine if your house was this size!

..you can't pass up a chance to train

where some of the British Olympic team practise their stuff.

Now for a test of coordination. Concentrate now, Jack!

And one arm the other.

And stretch!

And over the other side.

Come on, Jack. This time I know you can do the splits!

You're cheating! Move your bum forward.

-Oh, so close!

-Well done!

Now, time for the monkey bars. Chalk up, guys!

1, 2, 3. And let go.

Lovely finish, Courtney. Check out the roly polys!

-Look at the beam, though, not at me.

-Not bad, Jack.

-Oh, check you out. Pro already.

-They are naturals.

1, 2, 3!

-That is well cool.

-And it looks like it's fun, too!

He gets really excited.

Right, guys, I'm afraid it's time to jump off

and get ready for your maths challenge.

Today, one of the top British Olympic Gymnasts has taken

a break in his training to meet Jack and Courtney and give them

their 3, 2, 1, Go! challenge.

Hi, Jack. Nice to meet you. Daniel.

-I'm Courtney.

-Hi, Courtney. Nice to meet you.

Daniel Purvis became the world number one

men's artistic gymnast in 2011.

He's been the British all-round gymnastics champion twice.

He won gold in the World Cup,

and also got gold in the 2012 Test event.

So, you guys gymnasts?

-Yeah? Do you train here?

-No, not here.

-But I might join!

-What's your favourite apparatus?

-Jumping.

-I like doing balance beam.

-Balance beam, yeah?

-How did you learn this stuff?

I learnt it because I was very bad at football

so I decided to take up gymnastics. And yeah, it's a really fun sport.

-How old were you when you started doing gymnastics?

-I was seven.

It's been a very long time, but very good fun.

Right, I'm afraid we have to crack on here. Time for the challenge.

The clean shapes my body makes are how I score points in gymnastics.

In lots of positions, I also need to be symmetrical.

Take some pictures of my routines and see what shapes

and lines of symmetry you can see.

3, 2, 1, Go!

So Jack and Courtney have been given a shape-finding

and symmetry challenge.

They have to take photographs of Daniel's routine,

and spot what shapes and lines of symmetry his body makes.

Jack frames up and...

Good shot! Courtney's turn now.

Now, is that in focus?

Perfect!

Right, with their snaps developed, it's time to get to work

spotting the shapes and lines of symmetry they can see in his body.

-Shall I get the pen?

-Good start, Jack.

-From like...there?

-Good work - first shape found. A triangle.

Gymnasts need to make perfect shapes with their body

to win extra points, so knowing all of the shapes is vital.

-Any lines of symmetry?

-I see a symmetry line here.

-Yeah, OK.

-Going down, like that's the same as that.

-Exactly right, Courtney.

A line of symmetry is where the image on both sides of the line

-is exactly the same - a bit like a reflection.

-So like...

To make sure Daniel doesn't lose any points, it's important

he remains as symmetrical as possible.

-Any more shapes?

-I can see like a square shape here.

Yeah. Yeah, about there.

-And there's a symmetry going down.

-Yay.

Goes all the way down to the square here.

And they're spotting squares everywhere!

-That's a square.

-Well, sort of.

-This is like a square here.

And you've even managed to find shapes around Daniel's body

using just a couple of lines as clues. Good spotting!

Any more triangles?

There's like a scalene triangle here.

You think?

OK, amazing! Courtney has even managed to identify

what type of triangle she's found.

Any other shapes?

-Here.

-Oh, yeah! A semi-circle.

-Certainly is.

-That's good working.

-Well done to both of you.

-That's the only ones I can see.

So how many shapes and lines of symmetry have you found?

One, two, three,

four, five, six,

seven, eight, nine, ten,

11, 12, 13.

-I think that's all of them.

-So do I.

-Wow, that's loads!

Very impressive, guys. From expertly papping Daniel

to finding some all those shapes and lines of symmetry.

So how many of each did you find?

Four lines of symmetry.

-Three squares.

-Four triangles.

-One rectangle.

-And one semi-circle.

Courtney and Jack have completed their 3, 2, 1, Go! challenge

and it's time for their reward!

-Here for you, Courtney.

-Thank you.

-And some medals as well.

-Congratulations, Jack.

-Thank you.

-Congratulations, Courtney.

-Thank you.

Fantastic job.

Now your teacher has a challenge for you. 3, 2, 1, Go!

Sports people must be fast.

Strong.

And deadly accurate.

But did you know they wouldn't be able to compete without maths?

Timekeeping.

Scoring.

Speed.

-Go!

-And if they get it right...

-17!

..2...3...4.

What does he suggest?

He should dive to the bottom right corner.

They win a gold medal.

This challenge is all about cycling.

Track cycling takes place in specially built velodromes.

They are made up of two 180-degree circular

bends connected by two straights.

Cyclists race at speeds of up to 80 km per hour

on specially designed bikes with no brakes!

-So are you ready?

-CHILDREN: 3, 2, 1, Go!

Today, cycling fans Grace and Marek

are being taken to a secret location in Manchester

to complete their 3, 2, 1, Go! challenge.

There's only one thing on their minds this morning.

Cycling, because it's really fun to me and I like it.

Marek loves going out on his bike.

He is nine years old,

taught himself to ride a bike when he was five,

and goes cycling with his family whenever they can.

And what about you, Grace, where do you like to go on your bike?

I go playing out on it.

I go to the park as well.

Grace has just got a brand new bike.

She is eight years old and rides her bike every day,

and looks forward to the track cycling on TV.

They haven't clocked where they're going yet.

But there's no more keeping it secret - we've arrived.

This is the National Cycling Centre in Manchester,

and it was Britain's first indoor Olympic cycling track.

A cycle arena is called a velodrome. And this one is where

members of the Great Britain Olympic team are training.

This is where the guys are going to be given

their 3, 2, 1, Go! challenge.

Hi, Marek, hi Grace,

welcome to the National Cycling Centre. Do you want to come inside?

Marek and Grace are going to be given

their own special tour of the velodrome.

Look at some of the bikes up there that they used to race on.

Look at that one!

And they're just about to see the track for the first time.

Wow!

Yeah.

-It's wicked, that.

-And this is your lucky day.

You're about to get the track all to yourselves.

It's your chance to take a spin just before Team GB arrives.

Oh, but before you go, you should probably know -

-there no brakes on the bikes.

-What?!

-But will there be brakes on our ones?

-No, there's no brakes on your bikes.

-How will we stop then?

-With our feet.

-Yeah,

you have to slow down, pedal backwards to slow down.

Glad that's been cleared up. You'll be fine!

So are you ready?

-Awesome.

-Grace, don't look so worried!

First, it's a trip to the bike store to get fitted up.

Wow. Are these all the bikes?

This is the bike shed, this is where all the bikes are stored.

This isn't just any bike store. With 90 bikes kept in here,

it is the biggest fleet of track bikes in the UK.

And each bike is designed just for track cycling.

With no brakes, just one gear

and an aerodynamic frame, these bikes are built for speed.

Right, it's track time. Ready?

I'm shaking, look!

Aw, don't shake. You know how to ride a bike, don't you?

So don't steer, keep your front wheel straight.

And start pedalling.

First, a warm-up lap.

OK, can you set off yourself?

That's it. Well done. Nice and steady,

don't go too close to Grace.

That's it, keep pushing hard, well done.

Oi, take over!

So Marek's getting up to speed, but how fast can he really go?

-Let's do a time trial.

-OK, one lap as fast as you can. Go!

There he goes, high up on the sides,

just like the pros.

Come on, Marek, all the way to the line. Fast as you can.

-And while Marek's off, it's Grace to start.

-Go!

And here comes Marek to finish.

Keep pedalling when you finish.

Keep pedalling. Well done - 35.66.

Good job, Marek, brilliant time.

That's it, Grace, all the way to the finish line.

Come on, Grace! Come on! Pedal! I know you can do it!

-1 minute and 11 seconds.

-A very respectable time.

-How did you find that?

-Cool.

Top work. You racked up some fast times on the very track

our elite cyclists train and race on.

And today, a world champion has taken a break in her training

to give the guys their 3, 2, 1, Go! challenge.

Hello, I'm Sarah, what's your name?

-Marek.

-Hello, Marek. And you are?

-Grace.

-And how old are you guys?

-I'm nine. She's eight.

-Have you had a really great time on the velodrome today?

-BOTH: Yeah.

-Were you riding it yourself?

-BOTH: Yeah.

Sarah Storey is world champion in para-cycling.

She has competed at no less than five Paralympic games,

where she has won 18 medals.

She has an incredible 71 world records.

And Sarah has brought a few of her world championship medals

to show them.

I brought two so you can hold one each.

There you go.

I won these in Los Angeles last week.

It says individual pursuit -

that's over 12 laps of the velodrome here.

And that one says 500m so that's over two laps of the velodrome here.

How long have you been cycling?

I've been cycling since I was 27, so six years ago.

So I started when I was quite old compared to you guys.

How did you, like, ride it when you were 27?

Well, I'd already ridden a bike on the road

when I was a youngster, like you guys.

I learned to ride a bike when I was four, five years old,

just like everybody. But I was a swimmer before I was into cycling.

So I came down to this velodrome here

and got on a bike like the ones you used today.

And a person who's wearing a green jacket, who's in charge here,

taught me how to ride.

Now Sarah has got Marek and Grace's 3, 2, 1, Go! challenge.

-Listen up!

-In our races we have to keep a consistently high speed

so our competitor never catches up.

That means we have to pace ourselves perfectly.

In order to practise for this,

we do some training efforts over eight laps.

So I want you to time my team mates

to see how fast they complete each lap

and work out the difference between the fastest and the slowest lap. OK?

3, 2, 1, go.

So Grace and Marek have been given a timing and arithmetic challenge.

They need to measure how quickly Team GB cyclists

make it around the track.

And then work out the difference between the fastest

and slowest times. So how are you going to do it?

So I'm going to do the stopwatch, you do the writing.

Nice idea, Marek. So they have to start the stopwatch

when the first cyclist crosses the line to start their lap.

-And when do you stop the timer, Grace?

-Black line there.

-Yeah, I know.

-That's when you stop, so you have to press stop.

-Lap one.

-Go.

A stopwatch is a great way of timing accurately.

Faster, faster, faster, faster!

-30 seconds.

-How many seconds was that, Marek?

-30 seconds.

-Great, write that down, Grace.

Now time for the second lap.

(He's quite slow.)

-What was it?

-34 seconds.

34 seconds?! Must be a warm-up lap. Now for the third cyclist.

Man, he is going fast! Check him out.

-What was it?

-23 seconds.

-That's speedy!

Next one.

Cyclists and their coaches will often record their results

in a table like this to remember their times.

-Check him out.

-And number four comes in at the fastest yet,

20 seconds. So, we're halfway through. Here comes the fifth rider.

-That man is going fast.

-Yeah.

Look how high he is.

19 seconds.

Now for the sixth lap.

15 seconds.

-15? Whoa.

-Fastest so far.

Certainly is!

Comparing results is so much easier

when you present them in a table like this.

The cyclists are definitely getting faster.

That was fast.

Wow. Check him out!

18 seconds.

Just a bit slower this time. And finally, the eighth.

MAN SHOUTS

-That!

-Yeah, that!

Wow.

-18 seconds.

-Again?

-Yeah.

Top work. You've got all eight of your measurements now,

and some of the times were very fast.

The first cyclist completed their lap in 30 seconds.

The second took 34 seconds.

The third took 23 seconds.

Fourth was 20 seconds.

Fifth was 19. The sixth lap was 15.

The seventh was 18. And the last was also 18.

Now to work out the difference between the fastest and slowest.

First, they need to decide which was the fastest time.

So, fastest, 15 seconds.

Then which one was the slowest.

The slowest, 34.

And finally they need to figure out the difference between the two laps.

BOTH: 34 minus 15...

GRACE: ..Will equal...

So half of 30 is 15...

BOTH: Add 4...equals 19.

So that would be the answer.

Great job.

Knowing the difference between lap times

can help cyclists work out how much they need to improve

to be consistent.

You've taken some great measurements

and found the difference by using subtraction.

-What is the answer again?

-BOTH: 19 seconds.

They have completed their 3, 2, 1, Go! challenge,

and cyclist Sarah Storey has got their prizes.

Wow, you guys were amazing! I have trouble working out the difference

between my fastest and slowest laps sometimes so I was really impressed.

I want to present you with a certificate.

That one's for you and that one's for you.

I'd also like to present you with a gold medal.

These are even bigger than my gold medals,

and I'd like you to hang them

on your wall so you remember your day here at the velodrome.

Is that OK? I think you've had an amazing time

and you've done an amazing job as well.

There we go. Congratulations,

-give yourselves a round of applause.

-Great job.

OK. Now your teacher has got a challenge for you.

3, 2, 1, go!

Sports people must be fast.

Strong.

And deadly accurate.

But did you know they wouldn't be able to compete without maths?

Timekeeping.

Scoring.

Speed.

Shape.

Distance. It's all mathematics.

A tenth of a second, or just a few millimetres,

can transform an ordinary person into a world champion.

Great Britain get the gold!

This is...

-3, 2, 1..

-Go.

We take teams to a secret location.

This really is a special place!

-This is fabulous.

-To be given a behind-the-scenes tour.

THEY SQUEAL

And meet their sporting heroes.

Hiya, Jack, nice to meet you.

Who'll give them a maths challenge.

3, 2, 1, go!

-Go!

-Go!

-And if they get it right...

-17!

..2...3...4.

What does he suggest?

He should dive to the bottom right corner.

They win a gold medal.

This challenge is all about football.

Football is played on a rectangular grass pitch

up to 120 metres long,

and 90 metres wide.

Two teams of 11 aside kick a round ball into a goal

on the opposite team's half.

Only one player from each team can handle the ball

but only in the penalty box.

The games last for 90 minutes

and the team with the most goals wins.

So, are you ready?

3, 2, 1...Go!

Today, football fans Thomas and Zahida are being taken to

a secret location to complete their 3, 2, 1...Go! challenge.

First things first, who do you guys support?

I like Arsenal because my dad used to support them when he was younger.

Thomas is a massive football fan. He is 11 years old.

He wants to be a goalkeeper when he grows up.

And he trains at the Arsenal Soccer School three times a week.

-What about you, Zahida?

-Arsenal.

Zahida loves watching football matches on TV.

She is nine years old, plays football with her brothers

and, like all her family, she loves Arsenal.

-I just like them. They have good players.

-They certainly do!

In fact, they're one of the most successful British clubs,

winning 13 first division and Premier League titles,

two League Cups and no less than ten FA cups!

I've seen them once. When they won 7-1.

It was fun because there was loads of cheering.

Well, you're about to see them much more up close.

-Can you see where we're heading?

-Arsenal Training Centre.

Yep. You've got it.

Thomas and Zahida are about to get the treat of their lives.

This is where their favourite team, Arsenal, train.

With ten full size pitches, each to the exact specification

of their home stadium

they come here to prepare for all their matches.

But today the pitches are covered in snow, so they're training indoors.

Sort of!

It's a top secret location

and usually only the players are allowed in.

Hi there, welcome to Arsenal. These are for you.

If you'd like to follow me.

But today Thomas and Zahida get exclusive access.

-It's really big.

-There are players everywhere!

What do you think, Thomas?

-It's fabulous.

-And one of the top players has taken a break

and come to give them their 3, 2, 1...Go! maths challenge.

-Hi. What's your name?

-Thomas.

-Ah! And you?

-Zahida.

-OK.

Tomas Rosicky has played for Arsenal since 2006.

He's a midfielder.

And he has also captained the Czech national team.

He's been nicknamed "Little Mozart"

for his amazing orchestration on the pitch.

And it's rumoured that he was bought by Arsenal for £7 million.

-How are you?

-Fine.

-Do you support Arsenal?

-Yeah!

And who is your favourite player? Me? Me? What did you say(?)

-I like Van Persie.

-Same as him.

It's my favourite player as well, it's a good choice.

How does it feel to be worth millions?

That's a good question.

Enjoying just the football,

the business stuff, you don't think about it.

-You like to play football too?

-Yeah.

-You just enjoy the playing.

What was your favourite match so far?

Recently the one where we won 7-1. That was a great match.

Thomas knows all about that one, remember he was there!

Time for your challenge. Listen up.

So here's your challenge.

A football match is won by the team that scores the most goals.

You have ten shots at goal, add up how many you score

and work out what percentage went in.

3, 2, 1...Go!

First, let's find somewhere to complete the challenge.

This way, guys.

It's huge!

Did you ever think you'd be here, Thomas?

Never in a million years

would I see myself here.

My dad would want to be here.

Now a pitch just needs to be cleared of snow.

Good work, boys.

So they have been given a scoring challenge.

Enter 3, 2, 1, Go! goalie.

Some say no goal has ever been scored against him

and he hasn't left his net for over three years.

All we know is, he's called Two Gloves.

Thomas and Zahida have got ten shots at goal.

They then have to work out what percentage of those went in.

They need to make every single one count.

Thomas is the first

to step up to the challenge. There he goes with a strong right foot.

Great start, goal!

Don't get too caught up in the glory now.

You've got to mark it on the table.

Now next is Zahida.

She's taken the challenge very, very seriously.

Which way is she going to go?

She goes to her right.

And Two Gloves has saved it.

Organising their results like this

will help them remember how many of their penalties

they've taken, and how many they've scored.

Thomas again now. Third shot, come on.

Yes! He is on fire, the lad!

Back to Zahida. Come on, I know you can do this.

-Come on, Zahida.

-Lots of steps.

Oh, no! Zahida!

Saved again.

Keep your run of luck run going, Thomas. We don't want it to run out.

Oh, straight at Two Gloves. Oh, dear!

It's important that footballers keep track

of how many goals have been scored

to know who is winning the match.

The sixth shot from Zahida.

Bad luck. Straight at Two Gloves. He's saved another.

We need you to get this one, Thomas. Come on, get this one in.

Oh, not quite!

How lucky is Two Gloves?

The eighth shot for Zahida.

-Come on, Zahida!

-Encouraged by Thomas.

Two Gloves keeps it out again!

So unlucky, Zahida!

That's the fifth in a row saved. He's looking very confident now.

Come on, guys. Let's break his run of saves,

get some goals on the board?

Thomas, you need this one.

Oh, he's hammered it!

He's really done the team proud.

One last chance for Zahida.

Can she put it past the biggest, baddest goalie in town?

Come on, make it count.

Last chance.

Yay! More power in that one.

She scored!

Let's tot it up, guys. You've taken all your penalties.

First, a goal.

Then a save,

then another goal, followed by a run of five saves,

but finished off with two crackers.

So, of the total number of shots, what percentage went in?

-First up, what's your total?

-..six, seven, eight, nine, ten.

That's right, you took ten penalties.

So how many percent is each goal worth?

There's ten, so times by ten

-to get 100.

-Exactly.

Each goal is 10% of the total penalties.

So how many did you score?

-One, two, three, four goals.

-Brilliant. What next?

Times. Times these by 10, that's 40.

-So that must be 40%.

-That's right.

You got 40% of your penalties in.

Percentages are often used in football to indicate

a team's performance at goal scoring or possession.

You got a very respectable percentage of goals.

You stepped up to the challenge,

And got the ball past the notorious Two Gloves.

-What's your percentage again?

-BOTH: 40%!

Thomas and Zahida have completed their 3, 2, 1, Go! challenge.

Player Tomas Rosicky has got their prizes.

Zahida, here's your certificate.

-Well done.

-Thanks.

-And a medal.

-And for you, Thomas. Well done.

-Thank you.

Thank you.

Well done.

-It's great.

-Great job, guys.

Now your teacher has a challenge for you. 3-2-1, Go!

So far, we've seen that strength, coordination

and balance are important in gymnastics.

But also that a floor routine contains all sorts

of different shapes and lines of symmetry, and it's really important

for gymnasts to know and hold

those shapes and lines for top marks.

Gymnastics fans Courtney and Jack were brilliant at spotting them...

Here's A semi-circle.

Scaling a triangle here. Don't you think?

-A symmetry line here.

-Yeah, OK.

And that's the same as that.

..finding enough to earn them gold medals.

That was good work.

We've also seen that measuring time in cycling helps the athletes

know if they're getting faster in their training.

And knowing the time difference between the lap times

helps them work out how much they need to improve to be consistent.

Because in a race, consistency is a key part of winning.

That was fast!

Cycling fans Marek and Grace

timed and worked out the difference in lightening speed.

Equals 19.

-They did a great job.

-There we go, congratulations.

Then Arsenal fans Thomas and Zahida

found out how important it is to keep track of scores

so you know which team is winning.

And to work out percentages to know how the team is performing.

..ten divided by 100.

-They scored some fantastic goals.

-Oh, yes!

And were very fast in completing their challenge.

-Well done.

-It's great.

Coming up, two sports fans get to see

Britain's elite athletes in training...

Normally only allowed in this room if you're top 15 in the world.

..before lending rowers a hand working out their stroke rate.

Start!

Two rugby fans get to meet their heroes...

Callum. What's your name?

..before tackling the maths

behind the perfect up and under.

One, two,

three, four,

five, six, seven...

So, are you ready?

Sports people must be fast.

Strong.

And deadly accurate.

But did you know they wouldn't be able to compete without maths?

Time-keeping.

Scoring.

Speed.

Shape.

Distance. It's all mathematics.

A tenth of a second or just a few millimetres can transform

an ordinary person into a world champion.

This is...

-3, 2, 1...

-Go!

-We take teams to a secret location.

-This really is a special place.

It's fabulous.

To be given a behind the scenes tour...

-..and meet their sporting heroes...

-Nice to meet you.

..who'll give them a maths challenge.

Three, two, one, go!

-Go!

-Go!

And if they get it right...

17!

Two, three, four...

Probably get it through, if he dives to the bottom right corner.

..they win a gold medal.

This challenge is all about rowing.

All Olympic rowing races

are 2,000 metres long

with six lanes.

The boats, or shells, can have one, two,

four or eight rowers in them.

And some have a cox to steer them.

The rowers have either one or two oars each.

They paddle together in a straight line

and the first to cross the finish line wins.

So, are you ready?

Today, rowing fans Solomon and Lili-May

are being taken to a secret location near Maidenhead.

Lili-May is into lots of sports,

but there's definitely a theme to her favourite ones.

Anything water based like synchronised swimming,

speed swimming, canoeing.

Lili-May loves to be out in the water. She is ten years old

and has been a member of Caversham Canoe Club for two years

She attends synchronized swimming training six times a week.

Solomon is also really into sports. His list is as long as his arm.

Quite a lot of sports like cycling,

rugby, football, cricket, and lots more.

Solomon also likes being out on the water.

He is ten years old.

He's been to the Wargrave boating club for two years,

but recently he's been joining Lili-May at Caversham Canoe Club.

Now, can you see where we're going yet?

Bisham Abbey National Sports Centre.

Yep, you got it.

And this isn't just any sports centre.

This is where any aspiring athlete dreams of training.

Bisham Abbey National Sports Centre,

right on the River Thames,

houses the UK's most elite athletes.

All of the British athletes that won gold in the Beijing Olympics

came through here. It's where all the GB Olympic rowing squads train

But it's not just them, over 100 different British Olympic

and paralympic athletes are training here too.

From hockey to synchronized swimming,

usually only the highest level of sports people are allowed in.

But today, Lili-May and Solomon are going to be given special access.

Hi, Lili, Hi, Solomon.

Welcome to the English Institute of Sport at Bisham Abbey.

Come in, I'll show you around.

You're normally only allowed into this gym

if you're in the top 15 in the world.

Now, that's exclusive!

This is where the athletes do their training and earn their gold medals.

Very busy gym today, athletes training hard.

We've got the GB women's hockey squad doing weight training,

and at the far end, we've got the light weight men's rowing squad.

They're all doing a session on the ergos.

And that is exactly where Solomon and Lili-May are headed for.

These guys are Olympic and world championships.

You're going to do a session just like them.

Do you want to get on the rowing machines?

Don't look so worried. You'll be fine.

How cool is this? They are actually training with the Olympians.

If you look in front of you. the guy on the left

without his top on won an Olympic gold medal.

You can tell your friends that you were rowing at the same time,

the same place as an Olympic champion.

Keep training like this and one day you may even make the Olympic team.

Give it all you can, Lili-May! Dig deep!

The guys have been given a fantastic sneak preview

of what elite training looks like.

But of course the real rowing doesn't happen on dry land.

Just outside the training centre is the River Thames

where the rowing teams get out on the water

and put all of that training in to practice.

Although they look like they've forgotten one of their boats.

-There's little seats for them to sit on.

-Just like the rowing machines.

How long do you reckon it would take to win a race?

Um, I don't know.

Well, one person who does know

has taken a break in her training to meet Lili-May and Solomon.

-Hello, I'm Anna. What are your names?

-I'm Solomon.

-I'm Lili.

Anna Watkins competes in the women's double scull.

With that event, she has won the world championship

and also come first in the world cup.

And at the Beijing Olympics, she took home a bronze medal.

-Are you interested in rowing?

-Yeah.

-And do you think you want to do it when you're older maybe?

-Yeah.

Who got you into rowing?

When I was a teenager, there was a family

I used to babysit the children of.

The mum said that she thought I might be good at it

because I was tall. And tall is good for rowing.

So I thought when I get the chance, I'm going to do that.

And that's what I did.

Which was your first club?

My first club was Newham College,

because that's the college I was in at university.

But what Lili-May really wants to hear about is the glory.

What was it like getting a medal?

Very exciting, because I could see in the crowd,

behind where we were standing to get our medals, my mum, dad and sister.

-That was really special.

-Well, it looks like Lili-May

and Solomon wouldn't mind a medal themselves.

First they have to get through their 3-2-1 Go! challenge.

-You ready?

-Yeah.

Right, as part of our training, we need to know our stroke rate,

a measure of how many times we pull the oars in a minute.

Can you estimate a rower's stroke rate

from watching just 20 seconds of a race?

Three, two, one...go!

So they've been given a counting and multiplication challenge.

To make sure Lili-May and Solomon can really see those strokes,

we've set them a little closer to the river.

Right, our challenge is to watch them for 20 seconds and find out

how many times they row, then find out how many strokes

they do in a minute.

Great, looks like you've got it.

Stroke rate is how many times a rower pulls the oars in a minute.

It's really important for rowers to know their stroke rate

as it's a good indication of how fast they are going during the race.

If stroke rate increases, so should the speed.

The catch here is that they don't get the full minute to count

the rower's stroke rate. They only get 20 seconds.

First things first.

Right, I'll get the timer. Let's wait for some rowers.

Lili-May has her eye out for the boats.

She's going to use the stop watch to keep track of time.

Can you see any, Lili-May?

Here they come.

-Start.

-One...

Rowers are often timed using stopwatches.

It's really important to get a precise measurement

because in a race, every second counts.

Four...

five...

-Six...

-Stop.

Great stuff. Time now to do the workings.

I'll get the pen.

OK, so that was

six strokes in 20 seconds.

Nice, so how many would that be in a minute?

20 seconds goes into 60 three times.

OK, so what's the sum?

So if we times six by three...

Great work, Solomon.

Doing multiplication is just repeated addition

but it's a much faster way of getting to the answer.

Equals 18 strokes in a minute.

18 strokes a minute! Done.

Spot on.

By observing, timing and counting the strokes,

Lili-May and Solomon were able to calculate the stroke rate

from just 20 seconds of data

How many again?

BOTH: 18 strokes per minute.

Very well done on your challenge today.

The guys have completed their 3, 2, 1, Go! challenge

and rower Anna Watkins has got their prizes.

Thank you.

And a big shiny medal.

Thank you.

-Thank you.

-Very well done.

Good work, team!

Great job, guys.

Now your teacher has a challenge for you.

3, 2, 1, Go!

Sportspeople must be fast,

strong,

and deadly accurate.

But did you know they wouldn't be able to compete

without maths?

Timekeeping,

scoring,

speed,

shape,

distance - it's all mathematics.

A tenth of a second or just a few millimetres

can transform an ordinary person into a world champion.

Great Britain get the gold!

This is...

-3 ,2, 1...

-Go.

We take teams to a secret location...

This really is a special place.

It's fabulous.

..to be given a behind-the-scenes tour...

HE SCREAMS

..and meet their sporting heroes...

Hiya, Jack. Nice to meet you.

..who'll give them a maths challenge.

Three, two, one, go!

-Go.

-Go!

And if they get it right...

17!

Two, three, four...

Probability suggests to dive to the bottom right corner.

..they win a gold medal.

This challenge is all about rugby.

Rugby union is played on a grass field,

up to 100 metres long and 70 metres wide.

Two teams of 15-a-side,

try to place an oval shaped ball at either end of the pitch.

The ball can be kicked forwards, but only passed sideways or backwards

Five points are scored for a try and a further two for converting it.

And tackling IS allowed. So are you ready?

CHILDREN: Three, two, one, go!

Today Rugby fans Callum and Kavelle

are on their way to a top secret location in Cardiff in Wales.

There they will complete their 3, 2, 1, Go! challenge.

-So how are you feeling boys?

-Totally excited.

Callum has loved rugby all his life. He is seven-years-old.

His favourite team is Wales,

and he watches all their games on TV

And he wants to be a rugby or football player when he grows up.

What's that outside there?

Kavelle is a big sports fan. He's eight-years-old.

He supports Wales and the Cardiff Blues.

Rugby is in his blood because some of his family play for Fiji.

-Oh, there's Millennium Stadium.

-There's no fooling these boys.

-Eagle-eyed Callum has spotted the secret destination.

-Cool.

The Millennium Stadium.

-We're going in the Millennium Stadium.

-Yeah, man.

The Millennium stadium is home to the Wales national rugby union team.

Every year it hosts the Six Nations home games in front of 74,500 fans.

It even has it's own retractable roof to keep everyone nice and dry.

Oh, yes, Wales, Wales.

This is where the boys will be given their 3, 2, 1, Go! challenge.

Hi, boys, welcome to the Millennium Stadium. Let's go.

But this isn't just any old way into the stadium.

Oh, no, this is way the players enter before their games.

-So when they get off the bus they come straight up here.

-Yeah.

The boys are following in the footsteps of their rugby heroes.

This is awesome. Look.

First up the boys get their own private tour

of the Welsh team changing rooms.

These are the same shirts they wear on the pitch.

I think the boys quite fancy themselves as part of the squad.

-This is long.

-You'll grow in to it one day Kavelle.

Now it's time for a quick bit of tackling practice.

See these baths. They fill these full of ice.

When they come off the pitch they sit here for two or three minutes.

-Kavelle is warming up for his maths challenge.

-But there's only six.

There's 15 players.

3, 6, 9, 12, 15.

They only have to be in three minutes, so they take it in turns.

Then they go and take a shower.

-Where's the shower?

-Shower's right here.

Don't press the button though.

HE SHOUTS OUT

After a refreshing shower it's time for the boys to see the pitch.

This is where every Welsh rugby player dreams of walking out.

-It's massive man.

-And Kavelle and Callum get it all to themselves.

If I was at the top it would be scary.

And which Wales fan wouldn't want to do this?!

Touch the post, touch the post.

Today, two of the Wales national team have taken

-a break in their training...

-Hello boys.

-Hi guys.

..to give the boys their 3, 2, 1, Go! maths challenge.

-How you doing? Hi, what's your name?

-Callum.

-Callum.

-What's your name?

-Kavelle.

-Kavelle.

-Nice to meet you boys. So, you enjoying it so far?

-Yeah.

-You are.

Lloyd Williams plays for the Cardiff Blues.

He plays scrum half, so he makes many of the tactical decisions.

He has earned six international caps.

And represents Wales in the Six Nations.

Harry Robinson loves playing at the Millennium stadium.

He plays on the wing.

His team is also the Cardiff Blues, and at only 18,

he's been selected as the youngest player of the Wales squad.

Yeah, we both like rugby.

OK, lads, enough of the chat,

it's time for your 3, 2, 1, Go! challenge.

OK, boys, here's the challenge. A key tactic in rugby

is the Garry Owen, or the up and under,

when you kick the ball as high and far as possible,

so I get there just as the opposition catches it.

So what is the perfect kick? I can run ten metres in a second,

so time how long one of my kicks stays in the air and tell me

where I need the ball to land to make the perfect up and under.

Three, two, one, go!

Tricky question, and one that will test their measuring and arithmetic.

The Garry Owen, or up and under, starts with a kick.

The aim is to get the ball as far up the field as possible.

But, while the ball is in air the player has to sprint to

the exact spot it will land.

That way he has a chance of winning the ball back.

What Lloyd wants to know is how far up the field

can he kick the ball, but be there just as it lands?

He's told them he runs at ten metres a second,

so to figure out where Lloyd should be aiming for,

Kavelle and Callum first need to time how long his kick

will stay in the air. Hey, cheeky!

Three, two, one, go!

Being able to measure time is important to rugby players.

Knowing when the game finishes is always handy,

but knowing how long your kicks last is even more useful.

-Three seconds.

-Not bad, Lloyd. Now time to work out how far

Lloyd can run while the ball is in the air.

They know the kick lasts for three seconds,

and they know he can run ten metres in one second.

So, how long can he run in three seconds?

If he can run ten metres in a second.

Ten times three equals, three times ten equals...

30.

For the perfect up and under he needs to run 30 metres.

Spot on, 30 metres is the distance Lloyd can run in three seconds.

So, 30 metres is the sweet spot Lloyd should be aiming for.

Getting the ball up the field but not out of his reach.

Let's mark it out boys.

BOTH: Six, seven, eight, nine,

10, 11, 12, 13, 14,

15, 14, 15...

Hang on. I think you might have skipped a couple of metres.

-STYLUS SLIPS OFF RECORD

-Start again!

BOTH: One, two, three, four, five

six, seven, eight, nine,

10, 12, 13, 14, 15,

16, 17, 18, 19,

20, 21, 22, 23, 24,

25, 26, 27, 28, 29, 30.

-Here.

-Well done lads, you've found the sweet spot

for the perfect up and under.

Running at ten metres a second for three seconds

you've worked out how far Lloyd can run.

And you've managed to show him just where he needs to aim for.

How far away is it again?

BOTH: 30 metres.

Congratulations, Callum, here's your certificate. Give me a high five.

And here's your medal. Well done, Callum.

Well done, Kavelle, well done mate for completing your challenge.

The boys have completed their 3, 2, 1, Go! challenge,

And players Lloyd and Harry have got their prizes. Great job, boys.

THEY SCREAM WITH DELIGHT

Now your teacher has a challenge for you.

Three, two, one, go!

So, now we've seen that stroke rate is very important in rowing.

Sports fans Lili-May and Solomon used multiplication

to work out how many strokes a team rowed in a minute.

Six strokes in 20 seconds. 20 seconds goes into 60 three times.

So if we times six by three, 18 strokes in a minute.

And they did it in record time.

Well done.

Thank you.

Well done, good work team.

And finally we saw that timing, distance and speed

are important in rugby.

Kavelle and Callum expertly worked out how far

Lloyd would have to run for the perfect up and under.

He can run ten metres in a second.

-Ten times three equals...

-30.

And completed their challenge with flying colours.

Give me a high five. Well done, Callum.

Well done, mate. Well done for completing your challenge.

Now let's see how YOU do in your challenges.

CHILDREN: Three, two, one, GO!
