Sophie

10:11

We are really struggling with q 22 or percentage and decimals

Mr Warbrick

10:12

Okay, this is a rounding question. What's the largest number (with 2 decimal places) that will round down to 24cm

Kacie

10:11

hi Charlotte!

Mr Warbrick

10:12

For example Sophie, 23.99 would round UP to 24 so it's not that. 24.50 would round up to 25cm so it's not that

We want the largest number in between that rounds DOWN to 24cm

Charlotte

10:14

Is everyone having a good morning?

Mr Warbrick

10:15

I am thank you! It's great to see so many of you invovled in the learning this morning :)

Kacie

10:15

I’m having a good morning

Chelsea

10:18

Im stuck on 22

Mr Warbrick

10:19

22 has been the trickiest for lots of people so far. It's a rounding question. You're looking for the largest possible number that will round to 24cm

For example, 23.99 would round to 24, but it's not the biggest number that would. 24.50 however would round up to 25cm so it must be smaller than that...

Chelsea

10:20

Ohh so 24.4

Mr Warbrick

10:20

Close, but a number to 2 decimal places, not just one

Mr Warbrick

10:21

Well done Olly, another person who's completed the task :)

Chelsea

10:22

24.44

Mr Warbrick

10:22

Closer! But wouldn't 24.45 also round to 24cm? So we can get a little higher...

Olivia

10:23

I don’t really understand Question 22

Mr Warbrick

10:23

This is the one I'm currently working with Chelsea on too! It's a rounding question - what's the highest number with 2 decimal places that would round to 24cm

Mr Warbrick

10:23

For example, 23.99 would round to 24, but it's not the biggest number that would. 24.50 however would round up to 25cm so it must be smaller than that...

Chelsea

10:23

24.49

Mr Warbrick

10:23

That's the one!

Anna

10:24

I don't understand Q28

Mr Warbrick

10:24

Good morning Anna! Start with working out what 10 laps of track 2 would be.

Olivia

10:24

Oh Ok thank you for helping 😊

Anna

10:25

362

Mr Warbrick

10:25

Ah no, you've just added 10, We need to multiply by 10. So, 352 x 10 =

Anna

10:26

452

Mr Warbrick

10:27

Not quite, remember we lift and shift when multiplying by 10. So instead of 3 hundreds for example, we'll have 3 thousands

Olivia

10:27

I was just going to answer the question but it moved me on to the next question, this happens every time I am stuck and come back to this chat.

Mr Warbrick

10:27

This seems to be happening to a few people. When you have finished that section, it will take you back to that question I think.

Anna

10:28

3520

Mr Warbrick

10:28

That's the one! Now, a 100 laps of track 4 is 41.8 x 100 (so we lift and shift 2 places this time)

Anna

10:29

4180

Mr Warbrick

10:30

Great, well done! So add 3520 + 4180 together to get your answer in meters. Then, change it to km for the actual answer

Grace

10:30

Mr Warbrick

10:30

Morning Grace!

Millie

10:31

im stuck on number 17

Mr Warbrick

10:31

Okay, so you use column addition to add together 25.6 and 134.8

Grace

10:31

the reason I was not on yesterday because I was on DoodleMaths and I was on it just then

Mr Warbrick

10:31

Not a problem Grace - glad you were still learning!
