  Hi, everybody.

• 00:01 - 00:02

  Happy Monday.

• 00:02 - 00:04

  I hope you all have a lovely weekend on a

• 00:04 - 00:05

  well deserved rest.

• 00:05 - 00:08

  Now, today we're going to be focusing on odd infractions.

• 00:09 - 00:11

  All right, now, we've done quite a bit on addition

• 00:11 - 00:13

  so far in year four, but we're just gonna be

• 00:13 - 00:16

  doing things a little bit differently using fractions.

• 00:16 - 00:18

  All right, So there's two things that you need to

• 00:18 - 00:21

  remember when you're odd and two fractions together.

• 00:22 - 00:25

  The first thing is that when you're Arden fractions, the

• 00:25 - 00:26

  numerator changes.

• 00:27 - 00:28

  No, the numerator, remember, is the top number.

• 00:29 - 00:32

  All right, so the number above the line on the

• 00:32 - 00:36

  fraction now the denominator must stay the same.

• 00:37 - 00:37

  All right.

• 00:37 - 00:41

  So although the numerator the top number changes when you're

• 00:41 - 00:45

  Arden fractions, the denominator the bottom number must stay the

• 00:45 - 00:47

  same. All right, so let's have a look at a

• 00:47 - 00:52

  few examples so you can use a piece of paper

• 00:52 - 00:54

  unfolded into different amounts.

• 00:55 - 00:56

  All right, so you can use a circle.

• 00:58 - 01:00

  You can fold it in half to represent halfs, or

• 01:00 - 01:02

  you can fold it into quarters or 16th.

• 01:03 - 01:03

  All right?

• 01:04 - 01:06

  Just to get you more familiar on DME or used

• 01:06 - 01:08

  to looking at fractions, Pectoral All right.

• 01:08 - 01:10

  So if you need to, you can do this to

• 01:11 - 01:12

  help you work out your Arden fractions.

• 01:13 - 01:17

  Because you can add the different sections together as opposed

• 01:17 - 01:18

  to just happen to work it out in your head.

• 01:19 - 01:19

  But that's up to you.

• 01:19 - 01:21

  That's something you could do if you need to.

• 01:21 - 01:22

  You all right?

• 01:22 - 01:23

  So let's have a look at this.

• 01:23 - 01:24

  First question.

• 01:24 - 01:26

  2/5. Add 3/5.

• 01:27 - 01:29

  Know our numerator changes.

• 01:29 - 01:31

  Remember the top number, but our denominator doesn't.

• 01:32 - 01:32

  So I have 2/5.

• 01:34 - 01:34

  I've got a pizza.

• 01:34 - 01:35

  It's in five pieces.

• 01:36 - 01:37

  I've got two of those pieces.

• 01:38 - 01:39

  I've also got another pizza on.

• 01:39 - 01:41

  I've got three pieces now.

• 01:41 - 01:44

  If I ard to on three together, what do I

• 01:45 - 01:49

  get? 123455 altogether.

• 01:49 - 01:51

  So that answer would be 5/5.

• 01:52 - 01:54

  Remember? 5/5 out of a hole.

• 01:54 - 01:57

  Five pieces are 25 pieces is a whole.

• 01:57 - 01:58

  So that would be one.

• 01:58 - 02:01

  So 5/5 or one next one.

• 02:03 - 02:03

  The answer is five.

• 02:04 - 02:05

  Fifth next one, 4/12.

• 02:06 - 02:06

  Odd. 6/12.

• 02:08 - 02:09

  Well, I've got four on.

• 02:09 - 02:11

  I've got 64 out.

• 02:11 - 02:13

  Six is 10 to the answer for that one would

• 02:14 - 02:14

  be 22nd.

• 02:15 - 02:16

  All right.

• 02:16 - 02:18

  So what I would like you to do now, boys

• 02:18 - 02:19

  and girls, I would like you to have a go

• 02:20 - 02:23

  at the varied fluency questions that are below this video.

• 02:24 - 02:26

  All right, so what you have to do in those

• 02:26 - 02:27

  questions is odd.

• 02:27 - 02:28

  Your fractions together.

• 02:29 - 02:30

  Remember your your denominator.

• 02:31 - 02:32

  The bottom stays the same.

• 02:32 - 02:32

  All right.

• 02:33 - 02:35

  It's just the top number that changes when you're adding

• 02:35 - 02:37

  fractions. All right, so I hope you get on the

• 02:37 - 02:38

  right with those.

• 02:38 - 02:38

  Everybody on.

• 02:39 - 02:39

  I'll see you all soon.

• 02:40 - 02:40

  Bye for my boys and girls.
