Binomial Expansion – 3.5.16

Hi all,

Well done for the work in this topic – you’ve all done brilliantly and have completed C2 now – yay! See the Revision blog for ideas and resources, and comment below if you have any particular requests for revision lessons. Otherwise, just keep the past papers coming. Remember that your Chapter 4 assessment average was over 88% which is superb!

Your homework from today was to finish off the Mixed Exercise (5E) and I will collect that in along with you Ex5C and 5D on Friday. Your assessment is due on Tuesday.

Some common binomial mistakes are given below:

For extra work/extension work, see these 1951 exam questions: here and here as well as this Oxford Maths Aptitude Test question here.

See you on Friday,

Mrs Shaw

 

Equation of a Circle – 15/4/16

Hi all,

On Friday’s lesson we continued with our co-ordinate geometry work by investigating the equation of a circle, before you had a go at lots of activities helping you to remember this.

The first task asked you to match up the cards below from here and put them into the table, before filling in the blanks.

You then had a go at the Venn diagram task, asking you to complete the following:

If you’d like to have a look at some extension work, see this “Teddy Bear” activity from Underground Maths.

I was really impressed with the quality of your homework from Tuesday’s lesson and I look froward to collecting your Exercise 4D work on Tuesday.

Enjoy the rest of the weekend,

Mrs Shaw

 

Co-ordinate Geometry and Revision

Hi all,

Thanks for making such a positive start to the new term. You worked really hard today and managed to cope with all of the ideas really well. If you need any extra revision notes to help with your homework, see: C2 Ch4 notes. Don’t forget to ensure that you have completed all of the homework set today (selected questions from Exercise 4A, 4B and 4C) and marked/annotated it by Friday P1 – thank you!

I hope that you like your mathscards – click on the link if you’d prefer it as an app.

Next lesson we’ll start looking at the equation of a circle, feel free to read ahead in your textbook to familiarise yourself with the content. Don’t forget to ensure that you have completed all of the homework set today (selected questions from Exercise 4A, 4B and 4C) is done and marked/annotated by Friday P1 – thank you!

In terms of revision resources, remember to look at this post again.

I’m now going to try to put a countdown timer to the exams onto the blog – not long now!

Mrs Shaw

 

Reminder…

… if you are stuck on ANY of the work that you’ve been doing over the holidays, please comment below and I’ll give you some pointers.

Enjoy the last few days,

Mrs Shaw

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 🙂

Your homework for Easter is:

• Complete the assessment
• Complete the circled questions on this sheet (worked solutions available 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 😦

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 🙂

Last lesson you were using the “change of base” formulae for logs and completing 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 🙂

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

When going through the paper, if you find the mark scheme tricky to understand, this website looks really helpful: Exam Solutions – 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), see 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 in this document for a Venn Diagram task.

See you tomorrow,

Mrs Shaw
