What decimal did you get Olivia?

Olivia R

6:22

I did the first bit but when it said about squared numbers I was a bit stuck

Maria Dawber

6:22

Ok, so a square number is when you times something by itself. So 2x2 =4 so 4 is a square number

6:23

But that’s not between 5 and 0

So what could you try next?

Olivia R

6:23

Yes I know that bit but I was stuck when it said between 0 and 5

Maria Dawber

6:23

the square number needs to be bigger than 5, but still a one digit number

Olivia K

6:24

I have done it all but it moved me back to 25

Maria Dawber

6:25

It’s showing me that you have finished them all now Olivia :)

Evie

6:25

Olivia K

6:25

Olivia R

6:25

Ohhh Ok I get it thank you for your help Miss Dawber :)

Maria Dawber

6:25

You are welcome! Feel free to ask for any more if you need it!

Olivia K

6:25

Maria Dawber

6:26

Olivia K, it sent you back to 25 because you hadn’t finished it

Sam

6:29

I don't no what to do on 26

Maria Dawber

6:30

Again, you need to take each digit one at a time Sam

Evie

6:29

Im stucm on number 15

Maria Dawber

6:32

If you are rounding to the nearest tenth then you need to look at the hundredth column and look for high 5

Olivia R

6:29

Q30 is confusing me

Maria Dawber

6:29

I was just looking at that one! Start by working out the circle using the bottom row

Olivia R

6:30

How do I do that? Add all the decimals on the bottom row together?

Maria Dawber

6:31

There are 4 circles which add up to 1.28 so work out what one is worth

Olivia R

6:32

Ohhh Ok :)

Maria Dawber

6:32

How are you getting on, Sam?

Evie

6:33

Im stuck on 15

Maria Dawber

6:33

I just replied to your message Evie

if you are rounding to the nearest tenth then you need to look at the hundredth column and look for high 5

6:35

Sam you would’ve been corr3ct, but it says all digits have to be different. Think of 2 other digits which add together to make 7

Oliver b

6:36

Hi. I am stuck on question 30

Maria Dawber

6:36

Start with the bottom row Oliver. 4 circles make 1.28 so what is one worth?

Oliver b

6:37

0.7

Maria Dawber

6:37

No, 4 lots of 0.7 would be 2.8 not 1.28

Maria Dawber

6:38

What is a quarter of 1? And what is a quarter of 0.28?

Oliver b

6:40

A quarter of 1 is 0.25 and a quarter of 0.28 is 0.07

Maria Dawber

6:40

Excellent so add these together and you get a circle

On Q28, I worked it out with Mr Warbrick so I thought I had it right but it marked it wrong

Maria Dawber

6:41

Remember to write your name so I can look at your work

Olivia R

6:42

Sorry I forgot to type my name

Maria Dawber

6:43

It’s saying it is correct Olivia so don’t worry :)
