0:00:37 > 0:00:41Today, I want to practise a game of Estimate!
0:00:41 > 0:00:46- And...- Wow! I want to play! I want to play!
0:00:46 > 0:00:48OK, I'll show you how to play.
0:00:48 > 0:00:51- It's called Estimate... - I can do that!
0:00:51 > 0:00:54- Know what "estimate" means?- No.
0:00:54 > 0:00:58It's like guessing and you've got to look and think.
0:00:58 > 0:00:59OK...
0:01:01 > 0:01:05I wait to see how many things there are, then...
0:01:09 > 0:01:12..if I think it's near my number,
0:01:12 > 0:01:14estimate six!
0:01:17 > 0:01:21Yeah, I think there are about six dots.
0:01:21 > 0:01:23Hang on, hang on.
0:01:23 > 0:01:28There's one, two, three, four, five dots there! Not six!
0:01:28 > 0:01:33I didn't say it was exactly my number, I said estimate six.
0:01:33 > 0:01:37Could be six or a bit more or a bit less.
0:01:37 > 0:01:41- Clever!- Do you want a go?- Oh, yes.
0:01:42 > 0:01:45OK, I've got it.
0:01:45 > 0:01:51Could be the same as my number or a bit more or a bit less.
0:01:51 > 0:01:53Ready, go!
0:01:56 > 0:02:00Three, it doesn't have to be exactly your number,
0:02:00 > 0:02:04- it could be nearly your number. - Oh, yeah!
0:02:04 > 0:02:06Estimate three!
0:02:06 > 0:02:10One, two, three, four.
0:02:10 > 0:02:14Which is only a little bit more than three.
0:02:14 > 0:02:16- Well done.- Yes!
0:02:16 > 0:02:20Estimate! Estimate!
0:02:20 > 0:02:22- Do you want to go together?- Yes!
0:02:22 > 0:02:26BEEPING Oh! I want to play Estimate!
0:02:26 > 0:02:30Later, we've got work to do, come on.
0:02:48 > 0:02:51There's a call coming in.
0:02:51 > 0:02:54Agent 28 here. Things are going wrong.
0:02:54 > 0:02:55But not for long!
0:02:55 > 0:03:00- This boy is having problems. - Hold on, I'm putting it on screen.
0:03:04 > 0:03:08He needs four pieces to finish his construction.
0:03:08 > 0:03:12He can't work out which pile has about the right number.
0:03:12 > 0:03:16Because he's not deciding, the pieces do strange things.
0:03:16 > 0:03:19- Weird!- He'll never build that construction
0:03:19 > 0:03:23if they keep doing that. We'll send someone straightaway.
0:03:23 > 0:03:26- Thank you.- I'll go, 6.
0:03:26 > 0:03:28Get ready for launching.
0:03:28 > 0:03:31# We've got a problem What shall we do?
0:03:31 > 0:03:34# Who's going out there Who do we choose?
0:03:34 > 0:03:37# Need to get out there Who will it be?
0:03:37 > 0:03:39# Who's going out there? #
0:03:39 > 0:03:40Number 5!
0:04:04 > 0:04:06Good luck, 5!
0:04:06 > 0:04:08Checking the room...
0:04:08 > 0:04:12Hang on - someone there.
0:04:12 > 0:04:16- Oh, let me make the doorbell ring. - Go on, then.
0:04:16 > 0:04:18DOORBELL RINGS
0:04:18 > 0:04:23- There won't be anybody at the door. - Room clear.
0:04:23 > 0:04:26- I love doing that!- Let's go!
0:04:32 > 0:04:355...4...3...
0:04:35 > 0:04:372...1...zero!
0:04:43 > 0:04:45Looking for a 5 to land on.
0:04:50 > 0:04:52There's a 5.
0:04:56 > 0:04:59- OK, 5?- I'm fine.
0:04:59 > 0:05:02That's good. I think we've got more problems.
0:05:04 > 0:05:08Strange things are happening to the builder.
0:05:08 > 0:05:11She knows she needs six nails
0:05:11 > 0:05:17but she can't work out which pile has got about the right number.
0:05:17 > 0:05:19And while she can't decide,
0:05:19 > 0:05:22the nails are doing strange things.
0:05:22 > 0:05:23What is going on?
0:05:23 > 0:05:26I think I know - look.
0:05:26 > 0:05:28Oh, look!
0:05:28 > 0:05:30The Problem Blob!
0:05:30 > 0:05:33Bet he's the one making things go wrong.
0:05:33 > 0:05:36- We need all the information we've got.- Info on screen.
0:05:40 > 0:05:44# It's a spot, a glob of slime
0:05:44 > 0:05:48# Guess what this slob can buy
0:05:48 > 0:05:52# Great big and blubbery
0:05:52 > 0:05:53# Blubbery
0:05:53 > 0:05:55# Make big trouble
0:05:55 > 0:05:58# He's the flubbery Slubbery problem
0:05:58 > 0:06:00# Blub! #
0:06:00 > 0:06:04He slimed the builder to make things go wrong.
0:06:04 > 0:06:08Yes, look. The builder can't choose which nails to use.
0:06:08 > 0:06:11They're behaving strangely.
0:06:13 > 0:06:14More problems.
0:06:14 > 0:06:16Who is it this time?
0:06:16 > 0:06:18The man with balloons.
0:06:18 > 0:06:20- He's been blobbed!- Oh, no!
0:06:20 > 0:06:24He knows he needs about six balloons for his show,
0:06:24 > 0:06:27but he can't work out if he has enough.
0:06:27 > 0:06:31- He's having a lot of trouble! - Poor man.
0:06:32 > 0:06:34More problems.
0:06:34 > 0:06:39A teacher doesn't know if she's got enough children to help her.
0:06:39 > 0:06:42Blobbed! She's been blobbed!
0:06:42 > 0:06:46She needs about four children to help her.
0:06:46 > 0:06:51She can't choose which group has got about the right number.
0:06:51 > 0:06:54Don't say a teacher's in trouble!
0:06:54 > 0:06:58If she doesn't choose soon, the kids will behave strangely.
0:07:02 > 0:07:04You're right!
0:07:04 > 0:07:05Look!
0:07:05 > 0:07:08Poor lady.
0:07:08 > 0:07:125, we've got to sort these problems out.
0:07:12 > 0:07:16I know. If we don't stop the problem blob, things could get even worse.
0:07:17 > 0:07:20You want about four sandwiches.
0:07:20 > 0:07:24You can't decide which plate has got about the right number.
0:07:24 > 0:07:27The sandwiches might start behaving strangely.
0:07:27 > 0:07:33If you needed about three plants, but couldn't decide which pot,
0:07:33 > 0:07:36the plants might start acting strangely as well.
0:07:38 > 0:07:42If the dancing cow needed four shoes,
0:07:42 > 0:07:46but couldn't choose the right group, the shoes might go potty.
0:07:47 > 0:07:50We've got to sort these problems out.
0:07:50 > 0:07:53Agents, any ideas?
0:07:55 > 0:08:00It's because everybody can't decide if they've got the right number.
0:08:00 > 0:08:02How can they decide quickly?
0:08:02 > 0:08:07Wait a minute! What about our game of Estimate?
0:08:07 > 0:08:09No time for playing now, 3.
0:08:09 > 0:08:13No, I mean, could the people estimate what number it is?
0:08:13 > 0:08:15Yes, like we did!
0:08:15 > 0:08:17It's worth a try.
0:08:17 > 0:08:19We'll need to send them Brain Gain.
0:08:19 > 0:08:21I can do it! Me, me, me!
0:08:26 > 0:08:30# Brain Gain, Brain Gain To sort the problem, use a brain
0:08:30 > 0:08:35- # The way to get your brains linked up together!- Joined-up thinking
0:08:35 > 0:08:38# Getting brainpower now Brain Gain. #
0:08:39 > 0:08:41Let's start with the builder.
0:08:41 > 0:08:44Estimate! Estimate!
0:08:49 > 0:08:52She's estimating.
0:08:52 > 0:08:54She knows she needs six nails.
0:08:54 > 0:08:57Just check if it's about six.
0:08:57 > 0:09:00One, two, three,
0:09:00 > 0:09:05four, five, six, seven.
0:09:06 > 0:09:08It WAS about six.
0:09:08 > 0:09:09Well done, that builder.
0:09:09 > 0:09:12- Sort the others now, 5.- OK.
0:09:12 > 0:09:14Keep the Brain Gain going, 3.
0:09:14 > 0:09:16Estimate!
0:09:16 > 0:09:18Let's sort the balloon man.
0:09:18 > 0:09:20Time for some Brain Gain.
0:09:20 > 0:09:22Estimate!
0:09:22 > 0:09:24He's estimating.
0:09:24 > 0:09:27He needs about six balloons...
0:09:28 > 0:09:30..and he's got about six.
0:09:30 > 0:09:33Better sort everyone else, 5.
0:09:33 > 0:09:36Estimate, then count, if you want.
0:09:36 > 0:09:37Yeah!
0:09:41 > 0:09:46She's estimating. This group has got about four children.
0:09:46 > 0:09:48Counting to check.
0:09:48 > 0:09:53She's got one, two, three, four, five children.
0:09:53 > 0:09:55Very close to the four she needed.
0:09:55 > 0:09:58Her estimating worked fine.
0:09:58 > 0:10:00Do the boy and his construction.
0:10:05 > 0:10:08He needs to estimate
0:10:09 > 0:10:10which lot is about four.
0:10:10 > 0:10:12Counting to check.
0:10:12 > 0:10:16One, two, three, four, five.
0:10:16 > 0:10:18Very close.
0:10:18 > 0:10:21Well done, 5. We did it!
0:10:21 > 0:10:24Estimating sorted things out.
0:10:24 > 0:10:28One more thing still to sort out - the Problem Blob.
0:10:28 > 0:10:30THE PROBLEM BLOB GURGLES
0:10:30 > 0:10:33How can we stop it doing weird things?
0:10:35 > 0:10:40Estimating sorted the other things. Try it with the Problem Blob.
0:10:40 > 0:10:44OK, 5. You've got to make the Problem Blob spurt some blobs.
0:10:44 > 0:10:47And then we'll estimate how many.
0:10:47 > 0:10:49OK, I'll make him spurt.
0:10:49 > 0:10:51Be careful.
0:10:51 > 0:10:54And you get ready to estimate how many blobs.
0:10:54 > 0:10:59Problem Blob, we're estimating how many globs of slime you make.
0:10:59 > 0:11:02- THE PROBLEM BLOB MOANS - He didn't like that.
0:11:02 > 0:11:07Come on, blobbery blubber. Blob us. We'll estimate how many.
0:11:09 > 0:11:11Quick! Find the blobs of slime!
0:11:15 > 0:11:18Brain Gain to help you estimate.
0:11:19 > 0:11:23- Estimating about five blobs. - Looks good to me.
0:11:23 > 0:11:27One, two, three, four, five!
0:11:27 > 0:11:28Excellent estimate!
0:11:28 > 0:11:31Ha-ha, blobbery!
0:11:31 > 0:11:32He's getting angry.
0:11:37 > 0:11:39Estimate! Estimate!
0:11:39 > 0:11:41About how many?
0:11:41 > 0:11:43About ten!
0:11:43 > 0:11:45Estimates about ten.
0:11:45 > 0:11:47One, two, three, four,
0:11:47 > 0:11:50five, six, seven, eight, nine.
0:11:50 > 0:11:52Really close.
0:11:52 > 0:11:55- Great estimate. - We've got that blob beaten.
0:11:55 > 0:11:59- He's getting very angry! - He's going into overload!
0:12:03 > 0:12:07He won't be making any more trouble for a while.
0:12:07 > 0:12:09ALL: Yes!
0:12:09 > 0:12:11Come back now, 5.
0:12:11 > 0:12:12Hurrah!
0:12:17 > 0:12:19All clear for landing.
0:12:19 > 0:12:260, 1, 2, 3, 4, 5!
0:12:31 > 0:12:32Well done, 5.
0:12:32 > 0:12:34He was so blobbery!
0:12:34 > 0:12:37We've got it down on screen.
0:12:37 > 0:12:40- His pieces were all over the place. - I love those nails.
0:12:40 > 0:12:44I wish I had some.
0:12:44 > 0:12:47I'd like some of those balloons. They're mad.
0:12:47 > 0:12:51- Those children were strange too. - I wouldn't want to be the teacher.
0:12:51 > 0:12:56But we sorted them all. Estimate!
0:12:56 > 0:12:58Sorted them out by estimating.
0:12:58 > 0:13:00That's better.
0:13:00 > 0:13:02Even the children calmed down.
0:13:02 > 0:13:07- And we sorted the Problem Blob. - Well done, 5.
0:13:07 > 0:13:10And made the blob very grumpy.
0:13:12 > 0:13:14Go!
0:13:17 > 0:13:20Agh! Who put that there?
0:13:20 > 0:13:21Estimate!
0:13:21 > 0:13:24Not very close to my number 3.
0:13:24 > 0:13:28I estimate one problem blobbery blob...
0:13:31 > 0:13:33..and yes, I was right!
0:13:33 > 0:13:35One!
0:13:35 > 0:13:39Remember, you may need to estimate quickly. Can you do it?
0:13:39 > 0:13:41Get ready to estimate...
0:13:44 > 0:13:46..and then call the Numberjacks.
0:13:48 > 0:13:50- Estimate how many.- Good luck!
0:14:01 > 0:14:03# The Numberjacks are on their way!
