The main additions to the specification are listed below. This list is

**not**exhaustive, and some of the topics listed might have featured in previous specifications, but not for all exam boards. I've categorised topics as 'Year 12' and 'Year 13' as a guide, but timings will differ by school.

Free resources are listed for each new topic. This page is work in progress and will be updated regularly (Dr Frost's resources will be added when they are published). Please email any additional resources to resourceaholic@gmail.com. Note that I haven't linked to any resources which require subscription or purchase (eg Integral and Solomon), though I do recommend them if you have access.

My A level resource libraries will continue to be organised as 'AS' and 'A2' for school year 2017/18 (while the legacy specification is still being taught to Year 13).

**Proof**

**Year 12:**Understand and use the structure of mathematical proof, proceeding from given assumptions through a series of logical steps to a conclusion; use methods of proof, including proof by deduction, proof by exhaustion and disproof by counter example.

**Year 13:**Proof by contradiction (including proof of the irrationality of √2 and the infinity of primes, and application to unfamiliar proofs).

*|*The irrationality of root 2 |

**Inequalities**

**Year 12:**Solve linear and quadratic inequalities in a single variable and interpret such inequalities graphically, including inequalities with brackets and fractions. Express solutions through correct use of ‘and’ and ‘or’, or through set notation. Represent linear and quadratic inequalities such as y > x + 1 and y > ax^{2}+ bx + c graphically.**Note:**fractions in inequalities are new (e.g. a/x < b becomes ax < bx

^{2}) and graphical inequalities are new

Additional inequalities resources are available in my AS Core library.

**Graphs**

**Year 12:**Understand and use proportional relationships and their graphs.

**Year 12:**Understand and use graph of functions; sketch curves defined by simple equations including polynomials such as**quartic**functions and sketch the curve**y = a / x²**(including their vertical and horizontal asymptotes).

**Year 13:**The modulus of a linear function. Students should be able to sketch the graphs of y =|ax + b|. They should be able to use their graph. For example, sketch the graph with equation y = |2x – 1| and use the graph to solve the equation |2x – 1| = x or the**inequality**|2x – 1| > x

*Resources:*Functions Stack | Modulus Function Worksheets | Curve Match | Translating or not? | more to come...

Additional graphing resources are available in my AS Core library.

**Sequences**

**Year 13:**Increasing sequences; decreasing sequences; periodic sequences (recurrence relations).

*Resources:*Increasing, decreasing and not monotonic sequences video | Recurrence relations worksheet | Types of sequence and series | Final digit | more to come...

**Trigonometry**

**Year 13:**Understand and use the standard small angle approximations of sine, cosine and tangent.

*Resources:*Testing the small angle approximation | Video: small angle approximations | Video: applying small angle approximations | Sample chapter: The small angle approximations | What do functions do for tiny x?

**Exponentials and Logarithms**

**Year 12:**Use logarithmic graphs to estimate parameters in relationships of the form y = a^{x}n and y = kb^{x}, given data for x and y.*Linearizing data | more to come...*

**Year 13**:*Solve equations using the Newton-Raphson method and other recurrence relations of the form x*

_{n+1}= g(x_{n}) Understand how such methods can fail.

**Sampling**

**Year 12:**Understand and use sampling techniques, including simple random sampling and opportunity sampling. Students will be expected to be familiar with: simple random sampling, stratified sampling, systematic sampling, quota sampling and opportunity (or convenience) sampling.

**Year 13:**Conduct a statistical hypothesis test for the mean of a Normal distribution with known, given or assumed variance and interpret the results in context.

As a working mum I don't know how you find the time to do this but I'm extremely glad that you do!! (Mine are 11 and 16 and fairly self sufficient these days but I barely have time to read other people's blogs let alone maintain such a fabulous one!) I'm moving to a new school (selective grammar) in September and will have three year 12 classes and it seems your blog will be as helpful then as it has been during my training and NQT years and this year as my first year as a fully fledged teacher Thank you :-)

ReplyDeleteThanks! Good luck in the new job.

DeleteThanks for another enormously helpful post!

ReplyDeleteCheers, I'm glad it's helpful.

DeleteI shall be keeping a tag to this page handy, thank you so much. Any thoughts on how the data set in Statistics is going to work? Jenny

ReplyDeleteHi. I've not thought about it much yet. I won't get to the statistics part of the course until February 2018 so I will look into it then.

DeleteI'm still sulking about the impracticalities tbh. IT rooms are hard to book and the computers are unreliable at my school. But a bigger issue is that many students these days don't even know the basics of Excel. They study computing instead of ICT so they no longer learn Office skills. Given that the time constraints are ridiculous in Year 12, I can't imagine I'll have time to teach them Excel from scratch (or geogebra, or something else) and spend time leisurely exploring a data set in an IT room. It would be nice to do, but it's going to be a challenge. Perhaps it might be best done in Year 13 - reviewing statistical techniques using the large data set.

I'm sure it will all turn out ok! Edexcel have published some teaching materials here: https://qualifications.pearson.com/content/dam/pdf/A%20Level/Mathematics/2017/Teaching%20and%20learning%20materials/Data_set_activities_for_AS_and_A_level_Mathematics.zip

Thank you for your helpful reply. The knowledge of Excel(or lack of it) is certainly a big factor. I shall keep an eye out for any gems later in the year. In the meantime I am enjoying investigating your website, having recently found it, so many great resources, thank you for those too.
