0:00:08 > 0:00:11# To wherever they are needed They are speeding out today

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 > 0:00:37THREE HUMS
0:00:37 > 0:00:39# La-la-la-la... # Six!
0:00:39 > 0:00:43- Hey, Six!- I'm just going in the gym. - Great.
0:00:45 > 0:00:49- Oh, great, you've got one of your buddy blocks.- Yes.
0:00:49 > 0:00:53Cos you know you're buddy blocks can turn into buddy sticks.
0:00:53 > 0:00:57They certainly can. One buddy stick.
0:00:57 > 0:01:02Well, I've taught my buddy blocks to do the same thing. Go on.
0:01:07 > 0:01:13- Great. Not quite the same as mine. - What?
0:01:13 > 0:01:15The ends are round.
0:01:15 > 0:01:22Oh. Oh, yes. That's exactly what I wanted.
0:01:22 > 0:01:26Round. A circle at both ends.
0:01:26 > 0:01:29This is...a circle stick.
0:01:29 > 0:01:33Um... Can your other buddy blocks turn into circle sticks?
0:01:33 > 0:01:35Of course.
0:01:35 > 0:01:36Go for it!
0:01:36 > 0:01:39They're not quite the same.
0:01:39 > 0:01:42No, they're fine. Circle sticks.
0:01:42 > 0:01:46Sticks with a circle at both ends.
0:01:46 > 0:01:49That one's very tall.
0:01:49 > 0:01:50Lovely.
0:01:52 > 0:01:54BOTH: Oh!
0:01:54 > 0:01:55RATTLING
0:02:00 > 0:02:02And that one's very fat!
0:02:02 > 0:02:04BOTH: Whoa!
0:02:04 > 0:02:10Oh, maybe...maybe my circle sticks aren't quite ready yet.
0:02:10 > 0:02:13ELECTRONIC BEEPING
0:02:13 > 0:02:16- Never mind. We'll see them later.- Let's go.
0:02:26 > 0:02:29Come on, we've got a call coming in.
0:02:30 > 0:02:34- Four, come on!- I need to check the Brain Gain machine is OK.
0:02:34 > 0:02:40- We don't need it now.- Come on, Four. - Well, OK.
0:02:42 > 0:02:44Agent 44 here.
0:02:44 > 0:02:48- What's happening?- Things are going wrong.- But not for long!
0:02:48 > 0:02:50Look at this boy and his chalk.
0:02:50 > 0:02:53Putting it on screen.
0:02:59 > 0:03:01He can't draw at all with that chalk!
0:03:03 > 0:03:07- He needs help. - And we're the ones to help him.
0:03:07 > 0:03:08Thank you.
0:03:08 > 0:03:13- I'd like to help that boy.- OK. - In that case, Five is going out!
0:03:15 > 0:03:17# We've got a problem What shall we do?
0:03:17 > 0:03:20# Who's going out there? Who do we choose?
0:03:20 > 0:03:22# Need to get out there Who will it be? #
0:03:22 > 0:03:26- Who's going out there? - Number five!
0:03:50 > 0:03:52- Good luck, Five.- Thank you.
0:03:52 > 0:03:55Ready for launch. And I'm scanning the room...
0:03:59 > 0:04:01- And it's all clear.- Let's do it.
0:04:08 > 0:04:11ALL: Five, four, three
0:04:11 > 0:04:13two, one, zero!
0:04:20 > 0:04:23Finding a five...
0:04:23 > 0:04:25Finding a five...
0:04:25 > 0:04:27I've done it!
0:04:30 > 0:04:31Oh...oh.
0:04:31 > 0:04:34OK. Time to do some helping out.
0:04:37 > 0:04:39More problems!
0:04:39 > 0:04:44- Agent 63 here.- Where's the problem? - It's in the garden centre.
0:04:44 > 0:04:48- Can someone put it on screen while I check this?- On screen.
0:04:58 > 0:05:00She's struggling to move the wood.
0:05:00 > 0:05:04She's supposed to be helping the customers.
0:05:04 > 0:05:06She's making a mess instead!
0:05:06 > 0:05:08That's a very strange bit of wood.
0:05:08 > 0:05:10CLATTERING
0:05:13 > 0:05:17- More problems!- There's a man delivering a rolled-up carpet.
0:05:23 > 0:05:26I've a feeling this is going to go wrong.
0:05:29 > 0:05:31MAN: Whoa!
0:05:34 > 0:05:37That carpet is out of control!
0:05:40 > 0:05:43Why are all these things going wrong?
0:05:43 > 0:05:47Is there anything the same about the chalk, the big bits of wood,
0:05:47 > 0:05:49- and the carpet?- I don't know.
0:05:49 > 0:05:53It's the shape. They're all the same shape.
0:05:53 > 0:05:55Putting them on screen.
0:05:55 > 0:05:58Can you see what's the same about them?
0:06:00 > 0:06:04Oh! Oh! They've all got a circle at each end.
0:06:04 > 0:06:06Like my circle sticks.
0:06:06 > 0:06:09- Put them on screen, Three.- Oh, yes.
0:06:09 > 0:06:15They do look different, but they've all got a circle at each end.
0:06:15 > 0:06:20I think shapes with circles at both ends are called cylinders.
0:06:20 > 0:06:24OK, so we know what all these things going wrong are called -
0:06:24 > 0:06:27cylinders. But why are things this shape going wrong?
0:06:27 > 0:06:30I think I know. Listen!
0:06:30 > 0:06:31CACKLING
0:06:31 > 0:06:33It's the Shape Japer!
0:06:33 > 0:06:37- What do we know about the Japer? - This.
0:06:38 > 0:06:41# Looks like the Shape Japer's back
0:06:41 > 0:06:46# Shape Japer She's really strange
0:06:46 > 0:06:48# Shape Japer
0:06:48 > 0:06:50# She loves to make things change
0:06:50 > 0:06:55# Changes faces, changing size
0:06:55 > 0:06:59# Changing shapes every single time
0:06:59 > 0:07:04# Changing shapes is the Japer's game
0:07:04 > 0:07:06# The Shape Japer's back again. #
0:07:06 > 0:07:07Look.
0:07:07 > 0:07:10- Cylinder. - SHE LAUGHS
0:07:10 > 0:07:13- Wow!- She's got a circle at both ends.
0:07:13 > 0:07:17- Cylinder!- And I bet she's going to make trouble.
0:07:17 > 0:07:20- You're right.- I'm after her. - More trouble.
0:07:20 > 0:07:22Someone's got something to eat.
0:07:22 > 0:07:24I think there's going to be...
0:07:26 > 0:07:27..a problem.
0:07:37 > 0:07:39Cylinder!
0:07:39 > 0:07:41There's more trouble here.
0:07:49 > 0:07:51Oh, dear.
0:07:55 > 0:08:00- Is it another cylinder going wrong? - It's got a circle at both ends.
0:08:00 > 0:08:02Ha-ha-ha-ha!
0:08:02 > 0:08:04Cylinder!
0:08:04 > 0:08:05She's back!
0:08:06 > 0:08:11- Cylinder. Ha-ha-ha-ha!- The Shape Japer says these are cylinders.
0:08:11 > 0:08:15- She might be tricking us. - They're open at the end
0:08:15 > 0:08:20- and don't have a middle.- But they have got a circle at both ends.
0:08:20 > 0:08:25- Let's get some Brain Gain to sort these cylinders out.- One thing.
0:08:25 > 0:08:30- The Brain Gain isn't working very well today.- Oh, no!
0:08:30 > 0:08:32We'll only be able to use it once,
0:08:32 > 0:08:35so we can only fix one type of problem.
0:08:35 > 0:08:39We've got to be sure everything we send Brain Gain to
0:08:39 > 0:08:41really is a cylinder.
0:08:43 > 0:08:46- More problems! - Will they be cylinders too?
0:08:49 > 0:08:52The delivery man is in trouble again.
0:08:52 > 0:08:55It's very different from the carpet.
0:08:55 > 0:09:01- But it has got a circle at both ends. - More trouble in the kitchen!
0:09:01 > 0:09:04Is that cake a cylinder?
0:09:04 > 0:09:08Well, the top of the cake is a circle.
0:09:17 > 0:09:19And so is the bottom of it.
0:09:19 > 0:09:22If cylinders come in all these different types,
0:09:22 > 0:09:25there could be trouble anywhere!
0:09:25 > 0:09:30Tins of food in the supermarket have got circles at both ends,
0:09:30 > 0:09:33so they are cylinders that could go wrong.
0:09:35 > 0:09:37SLURPING
0:09:37 > 0:09:40A drinking straw is a long hollow cylinder,
0:09:40 > 0:09:43so that could be a cylinder that goes wrong!
0:09:43 > 0:09:45Ew! Oh!
0:09:45 > 0:09:49Or even a really short and fat cylinder like a cheesecake.
0:09:49 > 0:09:55If that goes wrong... it could be very messy!
0:09:55 > 0:09:59All those different cylinders! So may things to go wrong!
0:09:59 > 0:10:05We've got to put the cylinders right. I'll start the Brain Gain machine!
0:10:10 > 0:10:14# Brain Gain, Brain Gain To solve a problem, use a brain
0:10:14 > 0:10:17# The way to get your brains all linking up together
0:10:17 > 0:10:18# Joined-up thinking... #
0:10:18 > 0:10:22'Getting brain power now. Brain Gain!'
0:10:23 > 0:10:26Hope the different things were cylinders -
0:10:26 > 0:10:31- we've only got once chance with the Brain Gain!- Cylinder Brain Gain.
0:10:31 > 0:10:35- Cylinder Brain Gain! - Sending Brain Gain now!
0:10:38 > 0:10:41Cylinder Brain Gain now!
0:10:49 > 0:10:52Cylinders back to normal!
0:11:01 > 0:11:03Long cylinders back to normal.
0:11:05 > 0:11:09Cylinders with open end back to normal.
0:11:18 > 0:11:22Short fat cylinder back to normal.
0:11:26 > 0:11:29Thin, flat cylinder back to normal.
0:11:31 > 0:11:32Yes!
0:11:32 > 0:11:35The Brain Gain works for all of the things!
0:11:35 > 0:11:39Because they were all cylinders! Hooray!
0:11:39 > 0:11:45- Ha-ha...aaaargh!- She's not happy we've put everything back to normal.
0:11:45 > 0:11:49STRANGLED SHRIEKING
0:11:49 > 0:11:53- She's gone!- Hooray! - Come back now, Five.
0:12:00 > 0:12:02ALL: One, two, three,
0:12:02 > 0:12:05four, five!
0:12:07 > 0:12:11- Well done, Five.- Amazing, all those different cylinders.
0:12:11 > 0:12:14And you can see them all on the screen.
0:12:16 > 0:12:19The boy had trouble with cylinders.
0:12:19 > 0:12:22And the gardener and the delivery man
0:12:22 > 0:12:25were struggling with their cylinders.
0:12:25 > 0:12:30And the cylinders with open ends gave lots of trouble too!
0:12:30 > 0:12:33So did this cylinder.
0:12:33 > 0:12:36And the cake was a very messy cylinder.
0:12:39 > 0:12:42One lot of cylinder Brain Gain sorted out
0:12:42 > 0:12:45all those different-looking shapes.
0:12:50 > 0:12:55Well, my three buddy blocks weren't quite like yours, Six.
0:12:55 > 0:12:56Not exactly.
0:12:56 > 0:13:00- But they did help us solve the problem with cylinders.- True.
0:13:00 > 0:13:04Lucky my cylinders aren't doing strange things.
0:13:04 > 0:13:09Oh. Oh. Oh! Oh!
0:13:09 > 0:13:12You are very silly cylinders.
0:13:12 > 0:13:17I wonder, how many different sorts of cylinders can you find?
0:13:17 > 0:13:20Oh. Oh. Oh!
0:13:20 > 0:13:23Remember to look for a circle at each end.
0:13:23 > 0:13:27Find big cylinders, small ones, thin ones, fat ones,
0:13:27 > 0:13:32long ones, short ones and call the Numberjacks!
