Hi Mrs Tibble, i’m kind of confused on the first three questions(p 3, q5,6,7. The first one is “write the first five terms of the sequence with position-to-term rule(2xposition number)+10. They all follow the same structure… this is what i dont understand:
- is the position-to-term rule when you put the position numbers on top of the sequence numbers?
-which sequence?
- I dont understand the bit in brackets…Is it a bit like what we were doing in class today?
Thanks,
Nadia:D
yeah, i’m also stuck on those.
what does position number mean?
hey!
my facey picture thingy is WIERD!
mine is too! it keeps on changing!
i look like a GHOST!!
Verity, what do you think position number means?! It’s the number of your position lol.
So if you were first in the list, what would be your position number? What would it be if you were second? etc
Nadia,
not like today, like the previous lesson – working out the value of the term from its position in the list.
Examples from last lesson:
Sequence 1, 4, 9, 16, 25 etc
the value of the term was its position number squared.
Sequence 2 4 6 8 10 ……….
the value of each term is position number x 2.
Ok… but i still dont understand which sequence we’re supposed to be looking at… because it says position number x2 +10 and i cant see any sequence that starts with a number higher than 10…
OH!!! do you have to make up the sequence! i think its finally clicked now… thank you!
Q5 asks you to work out the terms of the sequence using that rule.
So, the first term has position number 1
The rule says multiply the position number by 2 and add 10.
There’s the first term of your sequence.
You won’t ‘see’ it until you create it!!!!!!!!!!!
YAY! Penny has dropped
sorry mrs tibble, but i’ve got another question: I’ve forgotten what the term-to-term rule is!:(
will you please have the patience to explain it to me again???
Wait. Is the term-to-term rule the difference between each number in the sequence? ex. 8,10,12 the term-to-term rule is add 2
Nadia, yes. It tells you how to move from one term to the next.
Hi mrs Tibble, i couldnt come 2 school today, because i injured my finger, so had 2 go 2 a and e: AGAIN. was there any maths homework today?
thanks,
Nadia
Hi Mrs Tibble,
I just needed to ask you about the Maths exam coming up in January. What is it on? Fractions? Sequences? Multiplication?
Thank you
Everything you’ve done this term.
Oh right……ok thankyou.
Hi Mrs T,
I am trying to open the mock exam paper for revision but it just says ‘file not found’. How do i get it onto my laptop?
Sorry i mean Mrs Tibble
Hi Emmanuelle,
I told Mr B about the problem but it looks like it wasn’t possible to sort it. Try using the Key Stage 3 revision link instead.
Happy New Year,
Mrs T
PS Mrs T is fine!!
Ok thank you! Happy New Year (for yesterday)
Hi mrs.Tibble i know i’m not in your class but im a tinsy bit confuzzled,well you no the arithmetic, say if you have +3++7 ino that in the end it equals 3+7=10 well what happens to the + infront of the 3??? and by the way what day is the dreaded TEST ;0
P:S HAPPY NEW YEAR 2010!!!
( sorry about the shouting in capitals 
)
Hi again mrs.Tibble,sorry i am asking so many questions but in this test coming up, will we be tested on those italian, russian and japanese methods of multiplying and divding? ( hope not
)be warned, i am doing revision so i will probaly hav loadz of questions ( sorry 
)
WELL, i am really stuck. With multiplying and dividing with arithmetic its really confusing: 3x-6 = -18 i don’t get how you could get thAT, and like uno when u hav signs different you – and signs the same u + well with timesing and dividing would you if signs were the same u x and with signs different u divide???
Hi Keavy,
Think of 3x-6 as three lots of -6 which is -18.
Multiplying and dividing are quite straightforward: do the sum normally (ignoring the signs) then use the rule about same signs and different signs.
eg -3 x -7
7×3=21 and minus x minus = plus
so answer is 21
-24/3
24/3 = 8
so answer is -8 because the signs are different
-72/-9 = 8 (here you can think of the minus signs cancelling if it helps)
Does that help?
With adding and subtracting, if the number is negative, do the opposite to what you would do if it was a positive number.
eg 7 + -6 = 7 – 6 = 1
Have fun
JT
Keavy,
Sorry, didn’t see your first question. If there’s more than 1 sign, losing a + doesn’t change anything so in your example
+3++7 = 3+7 = 10 like you said.
-5 – +6 = -5 – 6 = -11
This is because positive numbers don’t need to have a sign in front of them, whereas negative ones do ie +5 and 5 are exactly the same thing.
JT
mrs.Tibble, will we be tested on everything we have learnt last term, or just the things we have learnt after that test which put us in2 temorary sets???
Hi Keavy,
You will be tested on last term’s work, but, with multiplication, the method is up to you – you won’t be told which method to use.
JT
Mrs Tibble, I cannot find the mock Year 7 January test, where is it?
Hi Ellen,
Go to the tabs at the top of the page.

Hi Miss Tible, once again i was not in maths when i was going to do the maths exam. So shall i just do it when we have our next lesson? Because I’m getting kind of nervous about when. ????????????????????????????????????
Emmanuelle,
You can do it next lesson.

Hi Miss Tibble,
I dont really understand the plotting sheet that we got for homework. I’m finding it kind of complicated. :/
What can’t you plot?
Well, I know how to plot but I didn’t understand the instructions. But it’s ok now thanks. I understand.
Sorry but also, what is the difference between x and y coordinates? e.g. Write down the x coordinate of A. Write down the y coordinate of A.
Coordinates occur in pairs: the first one is the x coordinate, the 2nd is the y coordinate.
We are stuck on the angles question what is the angle for 12.30 we are confused on how to work it out
hi i am confused on the angles on the half pasts after 5:30 are the angles reflex?
Hi Jessica, try drawing it. Mark your clockface out in 30 degrees sections and count them up.
JT
Hi Ameera, the smallest angle between the hands is fine.
JT
are we doing from 12 to 12:30 to 1 etc.??
Hi Sian,
You are doing the angle between the hands for all the o’clocks – finishing what you started in class (acute/obtuse rather than reflex)
then the angle between the hands for all the half-past times.
JT
i am really stuck on the angles question for 12.30. please help.
thanks
I can’t do the angle question for 12:30. is anyone else online to help me with my homework querie????
Thanks x
Hi Kayla,
Sorry no-one was around to help you – teachers have been at a Year 9 parents’ evening.
Draw a small clockface and put the hands in the 12.30 position.
The angle between each of the numbers on the clock is 30 degrees until you get to the small hand which is halfway through the gap ie 15 degrees. Add them up and you’ll get the answer
(use the obtuse angle rather than the reflex)

Hi Mrs T,
What does SAS and ASA mean agin?
