0:00:02 > 0:00:04# In an ordinary room
0:00:04 > 0:00:08# Are extraordinary heroes who are standing by to zoom...
0:00:08 > 0:00:11# To wherever they are needed They are speeding out today
0:00:11 > 0:00:13# The Numberjacks are on their way
0:00:15 > 0:00:18# They will help you with your problems
0:00:18 > 0:00:21# They are waiting for your call
0:00:21 > 0:00:24# No problem is too big for them
0:00:24 > 0:00:26# No problem is too small
0:00:26 > 0:00:29# Things may all be going wrong but you can bet it's not for long
0:00:29 > 0:00:32# The Numberjacks are on their way
0:00:32 > 0:00:35# The Numberjacks are on their way! #
0:00:35 > 0:00:38Right, let's see how far I can jump.
0:00:38 > 0:00:41Easy jump to start. Hup!
0:00:41 > 0:00:44One, good start.
0:00:44 > 0:00:47Make it a bit harder. Hup!
0:00:47 > 0:00:51Two, and now, for three.
0:00:51 > 0:00:54Hup!
0:00:54 > 0:00:57Oh yes, getting harder though.
0:00:57 > 0:01:00Oh, it's a long way to get to the fourth one.
0:01:03 > 0:01:06Oh no, I'll never do it.
0:01:06 > 0:01:08- Oh yes, you will.- Eight!
0:01:08 > 0:01:12- I bet I can get you to jump further. - That will be great.
0:01:12 > 0:01:16- But how?- Well, go on, line up.
0:01:16 > 0:01:20- You can jump all the way to eight. - What?
0:01:20 > 0:01:23- You'll jump it because you have TWO jumps.- Wow!
0:01:23 > 0:01:27One jump to four, then another jump to eight.
0:01:27 > 0:01:30Two jumps, maybe I can do it.
0:01:30 > 0:01:32Here goes. Hup!
0:01:36 > 0:01:38- Yes!- Well done.
0:01:38 > 0:01:43- I jumped to eight!- And you thought you couldn't even jump to four!
0:01:43 > 0:01:45- Wow! Thanks!- No problem.
0:01:45 > 0:01:48BEEPING I've got a big mission to go on.
0:01:48 > 0:01:49Good luck.
0:02:08 > 0:02:12- There's a call coming in. - I jumped four blocks!- Great!
0:02:12 > 0:02:15- And four more! - Have to tell us later, Four!
0:02:17 > 0:02:22Agent 16 here, it's weird. Things are going wrong!
0:02:22 > 0:02:23But not for long!
0:02:23 > 0:02:26There's a girl and her umbrella.
0:02:26 > 0:02:28Hold on, I'm putting it on screen.
0:02:32 > 0:02:35That looks good!
0:02:35 > 0:02:38But it's very odd, it's got a life of its own.
0:02:38 > 0:02:42That is a weird umbrella.
0:02:43 > 0:02:47- And we'd better do something about it!- Great, thanks.
0:02:47 > 0:02:52- Right, who's going?- Well, Four's been doing some good jumping.
0:02:52 > 0:02:56- I have.- So maybe you're the one to go?- OK!
0:02:58 > 0:03:00# We've got a problem. What shall we do?
0:03:00 > 0:03:03# Who's going out there? Who do we choose?
0:03:03 > 0:03:05# We've got a problem to explore
0:03:05 > 0:03:09- # Who's going out there? - Number four. #
0:03:33 > 0:03:37Checking the room is clear...
0:03:39 > 0:03:42All clear.
0:03:42 > 0:03:43Stand by, Four.
0:03:50 > 0:03:52ALL: Four, three,
0:03:52 > 0:03:55two, one, zero!
0:04:02 > 0:04:04Scanning for a four to land on.
0:04:09 > 0:04:10Found a four.
0:04:16 > 0:04:17Whoa!
0:04:18 > 0:04:21- Right.- OK, Four?- I'm fine.
0:04:28 > 0:04:30Ooh!
0:04:31 > 0:04:33That buggy is out of control!
0:04:33 > 0:04:34CRASH!
0:04:34 > 0:04:38We've got to help everybody!
0:04:38 > 0:04:42What is it with these things? Is anything the same?
0:04:42 > 0:04:43Get them up on screen!
0:04:45 > 0:04:50Have you tried counting? Do they have the same number of things?
0:04:50 > 0:04:53The umbrella has four dark blue bits and four light blue.
0:04:53 > 0:04:57That's one, two, three, four, five, six, seven, eight.
0:04:57 > 0:05:03The buggy hasn't got eight things, it's only got four wheels,
0:05:03 > 0:05:05two at the front and two at the back.
0:05:05 > 0:05:07BOY: Hang on - look closely.
0:05:07 > 0:05:13The wheels are double wheels! So it's got four wheels at the front...
0:05:14 > 0:05:18GIRL: ..and four wheels at the back.
0:05:18 > 0:05:21That's eight wheels altogether!
0:05:21 > 0:05:24Two lots of four are eight.
0:05:24 > 0:05:26Thanks, agents. We've found what the link is.
0:05:26 > 0:05:28They've all got eight things.
0:05:28 > 0:05:32- Things with eight are going wrong. - But why things with eight?
0:05:32 > 0:05:36I'm not sure. But I can see something very strange.
0:05:36 > 0:05:40- The Shape Japer!- Ha, ha, ha!
0:05:40 > 0:05:43- Very tricky.- What do we know about the Shape Japer?
0:05:43 > 0:05:44Data on screen.
0:05:44 > 0:05:48Looks like the Shape Japer is back.
0:05:49 > 0:05:51# Shape Japer
0:05:51 > 0:05:55# She's really strange, Shape Japer
0:05:55 > 0:05:58# She loves to make things change
0:05:58 > 0:06:02# Changing faces, changing size
0:06:02 > 0:06:06# Changing shapes every single time
0:06:06 > 0:06:10# Changing shapes is the Japer's game
0:06:10 > 0:06:14# The Shape Japer's back again. #
0:06:14 > 0:06:18Why is the Shape Japer interested in eight things?
0:06:18 > 0:06:21Look at her corners. The Shape Japer has got eight corners.
0:06:21 > 0:06:25Four on top, and four on the bottom.
0:06:25 > 0:06:30- Eight corners.- Eight, bad, eight!
0:06:30 > 0:06:35She's being a bad eight and making all the other eights bad.
0:06:35 > 0:06:38We really need Numberjack Eight to sort this problem out.
0:06:38 > 0:06:42Well, you've only got me. Eight went off on his own mission.
0:06:42 > 0:06:46- Then you must solve this, Four.- OK.
0:06:46 > 0:06:50Agent 101 here - we've got more problems!
0:06:50 > 0:06:54This man's having trouble, I think it's his coat.
0:06:54 > 0:06:57- It's taken over! - Why is the coat going bad?
0:06:57 > 0:07:01Can anyone see anything special about it?
0:07:03 > 0:07:04CRASH!
0:07:04 > 0:07:07It's the buttons - count them!
0:07:07 > 0:07:09One, two, three, four,
0:07:09 > 0:07:14- five, six, seven, eight! - The number that's going wrong!
0:07:14 > 0:07:16Eight, bad, eight!
0:07:16 > 0:07:20AGENT: There's a lady doing funny things.
0:07:21 > 0:07:23- Oh, lady!- It's her hands!
0:07:23 > 0:07:26They're out of control!
0:07:26 > 0:07:28What's making her hands go funny?
0:07:28 > 0:07:30CRASH!
0:07:31 > 0:07:35It's the rings. Look - there are four on one hand,
0:07:35 > 0:07:37and four on the other. Eight!
0:07:37 > 0:07:40Another problem with eight!
0:07:40 > 0:07:45If we don't stop things with eight going wrong, anything could happen!
0:07:46 > 0:07:50If you were playing dominoes and you had a double four,
0:07:50 > 0:07:53that's eight! It might go mad and spoil the game.
0:07:53 > 0:07:57- Toot! Toot! - Or if you played eight notes,
0:07:57 > 0:08:02the instrument might go mad! Or horrible!
0:08:02 > 0:08:05TUNELESS TOOTING
0:08:06 > 0:08:10Or an octopus with eight legs might jump out of the water
0:08:10 > 0:08:13- and chase everyone! - PEOPLE: Ooh! Ah! Ooh! Argh!
0:08:17 > 0:08:21We've got to stop the Shape Japer making problems with eights.
0:08:21 > 0:08:25The Shape Japer is making eight bad all the time.
0:08:25 > 0:08:28If only we could make eight in a good way.
0:08:28 > 0:08:31Four - you can make eight, can't you?
0:08:31 > 0:08:35Oh, yes! In the gym, I jumped four and four and made eight.
0:08:35 > 0:08:37If your jumping was good then...
0:08:37 > 0:08:39It was brilliant!
0:08:39 > 0:08:42Then your jumping should be good here.
0:08:42 > 0:08:45- Two jumps by four to make a good eight.- It's worth a try.
0:08:45 > 0:08:48- Get the Brain Gain going! - Bouncing all the way!
0:08:48 > 0:08:52Two lots of four to make eight - it might just work!
0:08:56 > 0:08:59# Brain gain, brain gain
0:08:59 > 0:09:01# To sort the problem use a brain
0:09:01 > 0:09:05# The way to get your brains linking up together - joined-up thinking. #
0:09:05 > 0:09:09Getting brain power now! Brain gain!
0:09:10 > 0:09:13Two lots of four to make a good eight!
0:09:13 > 0:09:19- Two lots of four, two lots of four... - ..to make a good eight!
0:09:19 > 0:09:22- ZAP! - Wow!
0:09:22 > 0:09:24Sort out those bad eights!
0:09:24 > 0:09:27There's the buggy with the eight bad wheels!
0:09:27 > 0:09:30Ready, four? You've got to do two lots.
0:09:30 > 0:09:33Four...and four!
0:09:33 > 0:09:34Yes!
0:09:34 > 0:09:37Two lots of four made a good eight!
0:09:40 > 0:09:42Sort the rest of the things out now, four.
0:09:42 > 0:09:44OK.
0:09:44 > 0:09:47Sending more brain gain - two lots of four!
0:09:47 > 0:09:49Make those eights good!
0:09:51 > 0:09:55Two lots of four make a good eight!
0:09:58 > 0:10:01Two lots of four make a good eight.
0:10:01 > 0:10:04Two lots of four make a good eight.
0:10:11 > 0:10:15Well done, Four, two lots of four make eight every time.
0:10:15 > 0:10:19Phew! Glad I practised my jumping!
0:10:21 > 0:10:25- We got one more problem eight to deal with.- Where is it?
0:10:25 > 0:10:30- We don't know exactly but it's somewhere here.- Right.
0:10:30 > 0:10:31I'll have a look.
0:10:31 > 0:10:35OK, I still don't know what to look out for.
0:10:35 > 0:10:41- All we know is it's got something to do with eight.- Be careful, Four!
0:10:41 > 0:10:43I'm going to be careful...
0:10:43 > 0:10:46Aagh! It's a spider!
0:10:46 > 0:10:48Of course, with eight legs!
0:10:48 > 0:10:54One, two, three, four, five, six, seven, eight...
0:10:54 > 0:10:56very long legs!
0:10:56 > 0:10:59I think spiders are lovely.
0:10:59 > 0:11:01I'm not so sure.
0:11:01 > 0:11:05- Well, you haven't got to cuddle the spider.- Oh, good.
0:11:05 > 0:11:08- Just jump over it!- Oh no!
0:11:08 > 0:11:12Do you want this spider going bad like all the other things?
0:11:12 > 0:11:15- No.- That's what the Shape Japer wants.
0:11:15 > 0:11:17Eight bad! Eight bad!
0:11:17 > 0:11:22You've got to sort the spider. Two jumps of four to make a good eight!
0:11:22 > 0:11:25Two lots of four make a good eight!
0:11:27 > 0:11:29Here goes.
0:11:29 > 0:11:32Jumping the spider and back again.
0:11:32 > 0:11:34Four and four make eight!
0:11:34 > 0:11:38Now that's a lovely spider!
0:11:38 > 0:11:39Eight, eight!
0:11:39 > 0:11:42But not a lovely Shape Japer!
0:11:42 > 0:11:45Four's got one more thing to make good.
0:11:45 > 0:11:49Eight bad! Eight bad!
0:11:49 > 0:11:52- You can do it, Four.- Make that Shape Japer into a good eight.
0:11:52 > 0:11:55Two lots of four make a good eight.
0:11:55 > 0:11:57Get ready.
0:11:58 > 0:12:00Four!
0:12:00 > 0:12:03- Four!- And four more...
0:12:03 > 0:12:05- Argggh...- ..make eight.
0:12:05 > 0:12:07A good eight.
0:12:07 > 0:12:09Eight...
0:12:09 > 0:12:12Eight...
0:12:12 > 0:12:14Good...
0:12:14 > 0:12:19- She's being a good eight.- Done it! Come back now, Four.
0:12:23 > 0:12:26All clear for landing.
0:12:27 > 0:12:32ALL: One, two, three, four!
0:12:37 > 0:12:40Well done, four. You could do it!
0:12:40 > 0:12:42Yes.
0:12:42 > 0:12:46- Made that Shape Japer good for once. - We've got it on screen.
0:12:46 > 0:12:49The girl had trouble with her umbrella.
0:12:49 > 0:12:52And the buggy was going wrong too!
0:12:52 > 0:12:56They all have eight things.
0:12:56 > 0:13:00And Shape Japer was making all things with eight things go bad!
0:13:00 > 0:13:06The man had eight buttons and the lady had eight rings.
0:13:06 > 0:13:09- And the spider had eight legs! - That was a bit scary.
0:13:09 > 0:13:13But you did it. You made sure it was a good spider.
0:13:13 > 0:13:16And you made the Shape Japer good for once.
0:13:16 > 0:13:20- With two good jumps of four. - Everything sorted.
0:13:20 > 0:13:23Now, I'm going to help you just like Eight helped me.
0:13:23 > 0:13:26You jump two blocks,
0:13:26 > 0:13:29and two more.
0:13:29 > 0:13:30TWO GASPS
0:13:30 > 0:13:32Yeah!
0:13:32 > 0:13:35Well done, two at a time.
0:13:35 > 0:13:40I wonder, how many jumps would Two need to get to eight?
0:13:40 > 0:13:44Ooh, I don't know. Find out for me.
0:13:44 > 0:13:47How many jumps of two would you need to get all the way to eight?
0:13:47 > 0:13:50Find out and call the Numberjacks!
