I know you went though the other q’s 4 homework with us all in the lesson, but I am a tiny bit confused! :S
thanks x

Hi Aggie, Amelia, Harriet, Ella(who can’t spell her name lol!)
Aggie – if 2500 has been rounded to the nearest 100, (ie you are counting in hundreds) then whatever the true number is, it is closer to 2500 than 2400 or 2600. This means it must be from halfway between below to halfway between above – but remembering we round up not down. (Put on a number line to see what is going on)
Does that help?
yes I think so, well I will find out on our nxt maths lesson if I got that! Thanks Mrs T

Hey Mrs. Tibble, I am really confused by question 32, 33, 35 and 37, I have tried to do them but I really am struggling.
Hi Esther,
Q32. If the length is 20m corrected to the nearest metre, then it could be anything from 19.5 (lower bound) up to 20.5 (upper bound). However, that’s true for 10grams of wool, so in a 50g ball this could happen 5 times. The smallest possible length of wool in the ball is therefore 5 lots of 19.5m.
Does that help?

Hi Mrs Tibble.
I am so confused by the homework. I’ve done the first few, I am stuck on the same as Esther. Except 32, I think I can do that.
Hi Ella,
Q33 is the same as Q32. What are the lower and upper bounds for one of the tiles? Multiply each one by 10 to get the full range for the pack.
JT
I’ve done all the questions except 37 which I’m sort of confused about.
Erm, do we bring our books to the lesson tomorrow?
Ella Q37 – think about it!!
What will you write on if you don’t bring your book???? I can’t believe you asked me that!!
I get it, but I don’t know how to work it out.
Nooo, I mean as in do we bring them to the lesson for homework or do we have to hand them in. But I’m guessing lesson =]
Yes, the lesson lol!
Hey, Mrs Tibble, just signing in.
Hi Nicole
Hi Mrs Tibble, as Mr Atkins doesn’t have a plce here on the blog I was wondering could you help me on the maths h/w which Mr A gave us?
The questions are on pg 16 ex 1J in the ST(P) Mathematics 3A, erm, Q6 and 20. I am not sure how to work out the q, as it has a 0 in it? Please could you help me?
Aggie x
Hi Aggie,
What does the poster in my room say about power of nought???????????
AAAAAAAAAAAAAAGGGGGGGGHHHHHHHHHHHHHH!!
JT
PS Look in the grey box on page 14
I am stuck (like Aggie) on homework that Mr. Atkins gave us- q 2o. Anything to the power of zero is one but how to do write that?
erm, I can’t remember?!? :/ sorry, but I will look on the grey box on pg 14 though
Well Ella, you have a choice!!!!!!!
I like | myself, but some people like 1 or l; the Romans used I.
Please yourself
oh yeahhhh! I am so stupid! I remember doing that in yr 7 with you! lol I atch remem the lesson aswell!
I don’t think I will forget that now (maybe :/)
Thanks mrs t!
Hello Mrs Tibble and Mr Atkins Just Signing In =]
Ellooo, Just signing in
…
HELLO
Mr Atkins and Mrs Tibble 
I have finally signed in!!
Happy Christmas Zoe
signing in…
Hi sir, what we did in the lesson (pg 143 ex 7a q1-27) if found it easy but the h/w you set us I am slightly stumped! I know you went through it but I stupidly forgot 2 jot it down at the bk of my bk, so could you ple help me?
Thanks, Aggie
Hi Aggie,
You were asking me about this very same topic too!!!
You need to look at the terms and ask yourself what they are both multiples of ie their common factors.
Q1 4x + 4
Both terms are multiples of 4, so 4 is their common factor which goes outside the bracket.
Then to find out what goes inside the bracket, divide each term by 4 or ask yourself what you have to multiply 4 by in order to get each term
Since 4 x x = 4x
and 4 x 1 = 4
4x + 4 = 4(x + 1)
OK now?
JT
yes, that was what we did in class but the h/w was 28-37 and I know u r prob gunna tell me that it is the same method but i’m rly nt sure how 2 apply iy 2 them!
Aggie,
They are exactly the same except that there are 3 terms instead of 2 so the common factor/factors need to be in all 3 terms.
eg 5x + 10y – 25
All terms are multiples of 5 so it becomes 5(x + 2y – 5)
okay, I now understand that!
Thanks Mrs Tibble
was there any homework?
Aggie,
Yes – Ex 13C page 276 Q1-7 and 9
Put on my desk on Friday.
erm, I wasn’t in the lesson 2day so I’m a bit confused by the homework?
If I get the notes from someone 2moz then do u think that will help me?
Hello, I’m kind off stuck with question 4 on the homework! (page 276)
Please can you help me
(*)
Aggie,
Get the notes first, or work from the examples in the box (although it’s not set out exactly the same as the method we used in class)
Ruqayyah,
Leave the fraction uncancelled: the calculator can cope!
JT
PS By the way, you’re in year 9 now!!
Hi Mrs tibble, How’s it going?
Grace
Hi Grace
Your turn to make the tea!
I was just coming to see how things were, but they don’t look too hectic (or is that just an illusion!?)
I can give you a hand in about 15 minutes – or is that not at all useful and past the maths help rush hour??
(also, is there a way of changing my little character? I REALLY dislike my one.. It’s SO ugly!)
Help is always useful – I’m trying to mark trig questions!
Would you like to help Kioka divide numbers in index form?
I think you can change your character and upload your own if you register with wordpress.com. It’s free. Don’t get a blog, just sign up for an account using the details you use here and I *think* it’ll change your avatar. No promises!
Hello Mrs. Tibble
I’m slightly stuck on the homework that you set, q16.
I managed to get the answer of 18.57 on the trapezium but when this is multiplied with 420 it does not give the answer of 7800. What should I do?
hi mrs t, I think I have done q13 but the rest of them I have some issues with!
Please could u help me, I have apsolutly no idea what i’m doing!
Can u help me?
