Hints and Tips - 7 minute read
Steven Walker, OCR Maths Subject Advisor
Having recently posted my blog focused on studying GCSE (9–1) Maths at home, I’ve turned my attention to sourcing A Level Mathematics resources for your students to use whilst studying at home.
We have two specifications:
OCR A H230/H240 AS/A Level Mathematics
OCR B(MEI) H630/H640 AS/A Level Mathematics
All the A Level specifications were accredited against the same DfE criteria, but there are slight differences in interpretation. The main difference between OCR A and OCR B (MEI) is the structure of the examinations.
This means the majority of A Level Maths questions are appropriate for practice purposes, regardless of the specification you are following.
For a more detailed explanation read the frequently asked questions (FAQ) - why does OCR offer two specifications and what is the difference between the OCR A and OCR B (MEI) specifications?
We have published lots of free teaching resources that you can download for each of our A Level qualifications. Just select your qualification from the ocr.org.uk/maths web page.
Then select ‘Planning and teaching’ from the menu on the left to access:
Selecting ‘Assessment’ from the left-hand menu takes you to:
You can also find answers to FAQs for each specification.
The table below contains useful links to the support outlined above.
You may not have access to an electronic copy of your class textbook, but don’t panic, there’s a wealth of good quality maths support websites.
You may find sites such as CAIE, Khan academy, Maths made easy and Revision maths useful and there are plenty more listed in our delivery guides previously mentioned.
It’s worth noting here that candidates are never penalised for using alternative or more advanced techniques, unless the wording of the question specifically asks for a certain technique to be used.
If you find you are struggling with a particular A Level topic, it may be worth referring back to the fundamentals that you covered in the GCSE course. For ideas on sources of GCSE revision material read my previous blog on 'studying GCSE (9–1) Maths at home'.
It’s worth mentioning that the ‘use of technology’ is specifically referenced in the DfE criteria for A Level Maths (further details are provided in our specifications).
Some students working at home may be without a calculator, however basic scientific calculators are available on most mobile phones. For those that would like more, free graphing and calculator apps are available from platforms like Desmos and Geogebra (other calculator apps are available).
In addition to functionality that can be used in the exam, students may want to make use of a Computer Algebra System (CAS) to check work or develop deeper conceptual understanding. There are free online platforms that can be used, such as Wolframalpha, Solumaths and Symbolab.
Crucially, these platforms also have a vast wealth of prepared tasks and/or notes covering the breadth of content of the A Level Maths specification and beyond (again, other systems are available, some of which may need to be downloaded).
Used in conjunction with the specification, textbook and Check In tests these are useful interactive tools for developing a deep understanding of the content and they’re also helpful for checking answers too.
To illustrate, I have created the following parametric challenge graph in Desmos, which can easily be shared.
‘What are the parametric equations that create this curve?’
For extra support in using your actual examination calculator, Casio have a selection of tutorials, Texas Instruments have a number of resources and YouTube has a wealth of demonstrations for most calculators, just search the model and function to find examples.
The reformed qualifications have an increased emphasis on mathematical modelling and understanding the limitations of these models.
News coverage often refers to the predictions made, and the contradicting conclusions drawn from, mathematical modelling. Take a look at the recent +Plus magazine article ‘How can maths fight a pandemic?’ for some background information on the current COVID-19 modelling.
A basic simulation model, ‘Pandemics: how are viruses spread?’, has been provided by the NCTM and an interesting video on the Coronavirus curve was produced by Numberphile.
The possibility of performing mechanics experiments may be limited, but there are some activities that can be done at home.
The Downhill Race goes beyond the scope of A Level Maths, but a simplified version sliding toys down a slope, made from a section of drainpipe or shelving, allows an investigation of friction and is straight forward to set up. Collecting multiple sets of results also allows for some statistical analysis practice.
With whole families at home sharing equipment and bandwidth, practical investigations can also ease the pressure on technology and provide a break from screens.
We’ve been publishing puzzles via the @OCR_Maths twitter account that GCSE students can attempt; search the #OCRMathsPuzzle hashtag. These can be used to revisit the fundamentals, but they can also be used as starting points for further mathematical generalisation.
@OCRMaths #OCRmathsPuzzle from 21/02/2020
This puzzle nicely reviews GCSE equations of parallel and perpendicular lines, but how about finding a general equation for each line that cuts this rectangle in half?
Other sites with great short puzzles and activities include Nrich, Underground Maths, RISP, MSV, TES and many more.
We’ll also be regularly posting links to a variety of online resources in the coming weeks, so do follow us @OCR_Maths.
It’s worth remembering that Sir Isaac Newton developed many of the concepts included in A Level Mathematics during a period of social distancing, without the benefits (or distractions) of the internet.
There are so many great online resources available, so join the conversation by sharing your ideas and links to all your favourites in the comment box below.

Steven joined OCR in 2014 and has worked on the redevelopment of OCR’s Entry Level, GCSE (9-1), FSMQ and A Level Mathematics qualifications. He now focuses mainly on supporting the Level 3 qualifications. Steven originally studied engineering before completing a PGCE in secondary mathematics. He is currently balancing his ‘work from home’ commitments with supporting his young daughter with reception year activities.
