# Easter Work

Hi all,

Well done on your work today – hopefully you found it really useful to go through some of the questions – and I only ever gave you a tiny prompt to get you started – you did 99% of the work š

• Complete the assessment
• Complete the circled questions onĀ thisĀ sheet (worked solutions availableĀ here)
• Have a look through the mixed exercise questions which we didn’t get chance to look at today (worked solutions available here).

Please comment below if you get stuck with anything – I’ll get back to you asap.

Have a lovely Easter and well done on a superb half term,

Mrs Shaw

P.S. I spoke to IT and you should now be able to access the blog at school.

# Logs Update – Important!

Hi all,

As you know, this week I won’t have seen you at all, and next week I will only see you on Tuesday š¦

Since you’ve being doing so well on the individual logs exercises and producing superb homework, I thought it might be worth you trying to get you to work through the mixed exercise and complete the assessment for Tuesday, to allow me to mark it and you could make corrections over Easter.

However, it is a bit of a BEAST of a mixed exercise (we’d usually have spent those 2 lessons on it), so we will now spend Tuesday’s lesson looking at it and there will be heaps of extra questions that you can try if you have completed it. You can also complete your assessment in the lesson. Please ensure that you have had a go at ALL of the questions before the lesson though.

Thanks superstars,

Mrs Shaw

P.S. Reminder to those of you who I emailed about the folder work trawls – please bring in asap.

# End of Logarithms/Cover Work/Revision Idea

Hi all,

You’ve done really well on the logs work over the last couple of weeks – very well done š

Last lesson you were using the “change of base” formulae for logs and completingĀ the last exercise.

As I’m not in on Tuesday and you have Enrichment Day on Friday, your cover work is:

• Complete the Ch3 Mixed Exercise
• Complete the Chapter 3 Assessment.

Best of luck with it – remember P6s are still on or you can comment below for hints.

Thanks,

Mrs Shaw

P.S. Looking for C1 revision tasks? See these sheets from Corbett Maths – 5-a-day C1 questions to keep it fresh in your mind. Today’s sheet can be found below:

# Chapter 2 Assessment

Hi all,

I’ve just been marking your Chapter 2 assessments – and overall they were pretty good (an average mark of over 79%), however I’m using this blog to help some of you pick up some extra marks.

Two relatively uncommon, but easily corrected mistakes:

• Not rounding to 3sf when asked.
• Using incorrect sine and cosine rule formulae (definitely no excuses on an open book assessment!).

I’m also going to go over a couple of the less well answered questions – namely Q7b and Q8.

On Q7b it said that is cos(A) = 3/4, find the exact value of sin(A). The mark scheme gave two possible ways to answer this question – one was using the trigonometric identity below which I’m not sure if you have covered with Mrs P yet.

Alternatively, you could recreate the triangle which would give you cos(A) = 3/4 – see this solution by Mr McBride (sorry, my scanner isn’t working – this is a photo of what he wrote on one of your assessments during P6):

For Q8, you needed to use the ambiguous case of the sine rule (see this blog post if you need a reminder).

I’m going to give you a few hints, then if you could complete the question and resubmit it to me I can increase your assessment grade.

1. There are two possible triangles that could be created – find one of the missing angles and then do 180 – that angle to find the other one.
2. Decide if there’s any other information that you need before substituting into the area rule (clue – there is, don’t just substitute these angles in straightaway).
3. Find the areas
4. Find the difference between the areas.

# Mock Paper

Hi all,

Firstly, a massive congratulations for your superb results in your latest mock – they were much improved and well deserved š

The paper is available here:Ā June 2010 PaperĀ and the mark scheme is available here:Ā June 2010 MS.

When going through the paper, if you find the mark scheme tricky to understand, this website looks really helpful:Ā Exam SolutionsĀ – it goes through each question on the paper and provides a video of a worked solution. For similar things for other papers (including Statistics and Further Maths), seeĀ here.

You asked me to go through Q10c – see below!

See you tomorrow,

Mrs Shaw

# Laws of Logarithms – Extension Material

Hi all,

Last lesson your bell work was to decide whether the following statements were True/False:

You then got your papers back (more in next blog post), before you looked at the laws of logarithms and completed the corresponding exercise.

You’ve done really well with logs so far, so the slides below provide some extension material for you to have a look at.

This task requires you to use Card A initially to answer the other cards (you might not be able to do them in order):

And, see the first page inĀ thisĀ document for a Venn Diagram task.

See you tomorrow,

Mrs Shaw

# Logarithms – 1/3/16

Hi all,

Today we had our first lesson on Chapter 3 – you started by drawing some graphs of the form y = a^x and solving simple questions by reading off the graph (Exercise 3A).

You then completed Exercise 3B which was easy-peasy, just getting you to type some logs into your calculator.

We then spent more time converting between logarithmic and exponential form, before you completed Exercise 3C .Then you all played “Log Wars” – silly as the name is, you did really well on this and managed to do some logs in your head quickly. Rules are below and cards are here:Ā logarithm war cards.Ā

I then quickly spoke about how logs are used in the pH scale – might be particularly useful for those of you studying Chemistry. See the link on the slide for extra information.

Really well done for your work today, you picked everything up really quickly.

Best of luck for Thursday, I’ve got everything crossed!

Mrs Shaw
