hi mrs tibble
for q6 and q7 i don’t really understand them??
hi mrs tibble
i dont really understand q6 and q7 pg 19 u set us for homework??????????
Elise, question 6 is EXACTLY the same as the question we did in class putting fractions in size order, so look at today’s classwork and do the same thing: get all the fractions over the same denominator then you can see which is the smallest and which is the biggest.
Question 7 is just the same – write both fractions over the same denominator so you can compare them.
hi mrs tibble,
for q6 page 65 there are loads of diffrent modes so im not sure what to do???
elise
Hi Elise,
Asking maths questions first thing Saturday morning? Very impressive!
I thing you have misunderstood ‘mode’. From your question I think you are looking at anything that happens more than once but ‘mode’ really means the value(s) that happen most. If you’ve done your stem and leaf correctly, you will see 4 values that happen twice but there’s one that occurs 3 times, so it’s this value that is the mode.
Just for information – if there were 5 numbers that all occurred twice (and nothing more often than this) then there would be 5 modes, and you would list them all.
Does that help?
Mrs T
yes,thank you.
Elise
Hi mrs tibble
Merry christmas and a happy new year!
From gemma
HAPPY CHRISTMAS MRS TIBBLE AND A HAPPY NEW YEAR
FROM ELISE
Happy Christmas to you too Elise and Gemma.
Hope you have a lovely day. You can have a day off maths today if you like
Mrs T
Sorry it is late but have a Wonderful New Year!!
Gracie
Thank you Grace. You too
Hi mrs tibble, just wanted to know when our maths test is???
Hi Mrs Tibble
Happy New Year!!
I am revisiong pie charts at the moment and i know what to do but i am not sure how to do it with big numbers.
From Rachel Persaud
Hi mrs tibble, Happy New Year!!! Please could you tell me when the maths exam is, because i am revising????????????
Thanks
Hi Phoebe,
The test is next Monday in your maths lesson. Have fun
Mrs T
Hi Rachel,
Can you give me some more details or an example as I’m not sure exactly what you mean.
Mrs T
hi mrs tibble.
i dont understand q3 on page 37 and q2 on page 38
elise
Hi Elise,
Q3 Pg37: these are like the ones you did in class in the second part of question 3. You are given the longest length (it’s 17 in part a ) and one of the shortest length ( x in part a). Do what I said in class – use numbers first to work out what’s going on. What would the gap be if x was 5 or 6 or 8? How did you get the answer? Now do the same with x.
Look back at what you wrote for 3c and 3d in class, as these are just like that.
Q2 Pg 38
Simplify means tidy up so collect everything that’s the same together. If you need something visual to help you then invent things that the letters represent
eg in part a, if a is apples and b is bananas (!)
you have 24 apples and 6 bananas and 13 apples and 7 bananas
Instead of having 4 piles tidy them up into 1 pile of apples and 1 pile of bananas
Sometimes however you aren’t making the piles bigger (adding) but smaller (subtracting) so watch the signs.
Hope that helps. It’s not difficult – you are just panicking at the letters I think.
Have fun
Hi Mrs Tibble,
I have just read the reply to Elise. I understand the questions and what you have to do and i have completed the first two but they get harder towards the end. Could you help me?
Gracie
Sorry i didn’t make the page clear enough. P38 Q2
Gracie
Hi Grace,
Read each letter in turn and use the sign that is IMMEDIATELY in front of it.
eg 2c
for the m terms (mangoes?) you have 9 mangoes take away 7 mangoes
for the n terms (nuts?) you have 3 nuts take away 2 nuts
When you tidy that up, what do you have?
Do 2d the same way remembering that y is 1 y
Hi Mrs Tibble
I am stuck on question 1 on page 40!
From Rachel
Mrs Tibble,
Just wondering if this is the correct answer for Q3 a. Page 39
4 (little 4) * 5 (little 4)
Gracie
Hi Grace,
I’m so sorry but I forgot to put the HW book in my bag so I don’t have the question here.
However if I open up your answer, it would look like
4x4x4x4x5x5x5x5 with the order of these numbers not important.
Does that help?
Mrs T
Hi Rachel,
Is this the number wheel? Numbers opposite each other have to be added together and give an answer of -18.
I don’t have the book here but an example would be +2 and -20
Does that help?
Mrs T
That is fantastic, thank you Mrs Tibble!!
Grace
Yes it is the number wheel question. I kind of understand it, but I will try it.
From Rachel
Hi Rachel,
Work out what you think the right pair of numbers is, then check it on your calculator to see if you are right. Was -18 the right total?
Hi Tibble
I am stuck on question 1 page 43.
From Rachel P
Rachel,
Fill in the missing numbers to make the sums work.
First one: 5 x something = 90
Use your calculator!
Mrs T
But some of the sums don’t make sense.
Eg
9 something something divided by 6.
From Rachel p
Rachel, you are reading it wrongly. Have you ever done a crossword? You get blacked out squares where there are no letters. Here they’ve done the same thing, just used green instead of black.
Hi Mrs Tibble
Because I have been ill all weekend I am doing the homework that you set on the 26th now and I am a bit confused about pg 39 q6.
Ruby
Mrs Tibble,
I am struggling with p38 q4 c.
I don’t understand the BIDMAS and brackets.
Please could you help?
Grace
Hi Ruby,
When you have to divide, write the first one over the second one (like a fraction). Simplify the numbers in the same way you would cancel down an ordinary fraction, then subtract the powers for the letters eg x to the power of 5 divided by x cubed would be x squared because 5-3=2.
Hope that helps, and hope you are feeling better
Mrs T
Hi Grace,
B in BIDMAS means work out the bracket first.
In this question the bracket is (y + 3) which is 2+3 which is 5
The sum therefore becomes 3 x 5
( the 3 infront of the bracket means multiply because there is no sign there)
OK now?
Mrs T
Mrs Tibble,
I understand the example you gave me but where did you get the 2 from the y?
Thanks
Grace
Sorry, classic case of not reading the question properly
Grace
hi mrs tibble i don’t really understand q6 on page 38
Hi Elise,
You need to put the value of n into the expression and see if it gives the answer they say.
Think about what each expression means, eg what does 2n actually mean? What does n squared actually mean?
Don’t guess. Work out if what they say is true or not.
Hi Mrs Tibble,
I dont understand Q2 Page25
JC
Hi Juliette,
Read the info at the beginning more slowly and think about what it is telling you.
The selling price is 4 times the purchase (buying) price if it is milk, and 1.5 times the purchase price if it’s yoghurt.
The info given is the selling price and you have to work backwards to find the purchase price.
JT
Hi Mrs Tibble,
I dont understand Q6a and b on page26
JC
Hi Mrs Tibble,
Doesnt matter now i understand it, I just had to read the question.
JC
Mrs Tibble,
Please could you help me on Q3 A.?
Grace
Hi Grace,
What rule has been used to change the top numbers into the bottom numbers?
Look at the examples in question 5 on the previous page to see how to write them.
You call the input (top number) x, and then write what has happened to x as your rule.
eg in Q5 on page 25 diagram C, the output numbers are all 1 less than the input numbers so the mapping is x -> x-1
Does that help?
Thank you, thats very helpful
Grace
Mrs Tibble,
Its taking me ages to try to work out Q3 B. I am not sure how you would go about doing it. Please could you help me?
Sorry,
Grace
Hello Mrs. Tibble bit stuck on q4 p27, for the graph do you put negative numbers on one side and positive numbers on the others, i think so but just wanted to check
Lucy
Hi Lucy,
If you look at the instructions for the values to use, there are no negative numbers there so you don’t need all 4 quadrants for that question.
For question 6 do it like the one drawn for question 2.
