Mechanics – Dimensional Analysis

For UK Examination Boards AQA, OCR A, OCR B MEI Further Mathematics.
This posts gives details of the specifications and teaching resources for Dimensional Analysis.

First a look at the specifications and we see a similarity between all three specifications. For AQA see the first image below. OCR A and B (MEI) additionally mention the relationship between the units of a quantity and its dimensions, with OCR B MEI adding ‘be able to change the units in which a quantity is given’.

Specifications 
AQA: Optional application 1 – mechanics  Assessed at AS and A Level
AQA Dimensions Specifiication
AQA have a very helpful Teaching Guidance document for Mechanics, explaining how AQA have interpreted the content of the specification, the guide provides examples of how the content of the specification may be assessed.

The guidance is available on AQA’s free Maths portal for teachers, All about Maths. The resources are for teachers who offer, or are considering offering AQA maths qualifications. See this page for how to register.

AS Practice Papers and A Level are available on All About Maths

For some Legacy questions and mark schemes see the paragraph on MathedUp below.
The Legacy Mechanics 3 papers which included Dimensional Analysis are available on All About Maths.

OCR A Sample Question paper and mark scheme. Question 3 is on Dimensional Analysis.
OCR B Mechanics Minor (question 3) and Mechanics Major (question 6)
OCR also have practice papers – these require an Interchange log-in.

The Legacy M3 OCR MEI questions are very useful indeed for this topic. (No log-in required.

A Level Maths Revision very usefully provides Further Maths exam questions by topic (scroll down). Legacy questions from OCR MEI and mark schemes are available for Dimensional Analysis.

Further Resources

From amsp this brilliant collection of short videos produced by the legacy Further Mathematics Support Program supports the Further Maths Specification. I have used many of these successfully in class and recommended them to students to support their studies. Look at any of the examination boards to see the coverage for the course. Check the list for your examination board and you can find the videos on Dimensional Analysis for AQA, OCR A and OCR B MEI.

OCR Section Check In Tests and Delivery Guides
OCR have very useful check in tests on Dimensional Analysis with fully worked solutions for OCR A and OCR B MEI. These both seem to use the same questions.

Each check in has 10 questions, the first four questions are are routine procedural questions which primarily assess ‘Use and apply standard techniques (AO1)’ The remaining questions primarily assess ‘Reason, interpret and communicate mathematically (AO2)’ and ‘Solve problems within maths and in other contexts (AO3)’

At least half of the questions are appropriate for the AS course.

OCR A Delivery Guide Dimensional Analysis
OCR B MEI Delivery Guide Dimensional Analysis

These Delivery Guides discuss general approaches to the delivery of the topic, common difficulties and common misconceptions. A good approach, whenever a formula is taught, a dimensional analysis can be performed to check the validity. Both guides have the same suggested list of Further Resources including some good Nrich resources such as this article. The Springer notes are helpful, with clearly explained examples. The University of Guelph resource seems to have an unwanted full stop at the end of the address – the resource is here.

MathedUp – Mohammed LadakMathedupOn Mohammed Ladak’s ‘MathedUp’ see his A Level Further Maths Takeaway, a wonderful source of exam questions by topic with mark schemes. AQA questions have been used here.
A video of a legacy AQA question is provided, also four challenge questions with mark schemes.

Helm notes

For a very comprehensive set of notes with many fully worked examples and exercises, have a look at Section 47 of the HELM Project which was designed to support the mathematical education of engineering students and includes an extensive collection of notes which include very clear worked examples. For easy access to these resources, the HELM Project Workbooks are hosted by Loughborough University’s Mathematics Learning Support Centre. Alternatively, the complete set is hosted by the Open University. To access the Open University resources you will need to create an account (easy and free), this will also give you access to the numerous free online courses.

Further Mathematics Resources

The Further Mathematics Teaching Resources page is one of a series of Further Maths pages and is updated with any new resources. Additionally any posts which include Further Mathematics resources are now categorised as Further Mathematics A Level.

To highlight some recent changes:

TLMathsIndex

Jack Brown has created thousands of videos covering the complete A Level specification; the easiest way to navigate the videos is through his website, TLMaths.com.

Jack also has Further Maths teaching videos and exam paper walkthroughs. I see many useful videos on Proof, including the use of Induction for proofs of divisibility. This collection is growing and currently there are also videos available on many Complex Numbers and Matrices topics.

Jonny Griffiths Further RISPS

Jonny Griffiths investigative activities for the pure A Level Mathematics classroom are well known (details are included in the A Level resources pages, see RISPS.  He has now published Further Risps, forty rich tasks for the pure Further Mathematics classroom.

Two editions are available – a hard copy or pdf versionThe pdf version is now available free from www.further-risps.co.uk. On this page you can see two trial activities, Further Risps 1 and 2.

The pdf not only provides the forty problems but also full teachers notes for each. The notes for each task begin with the topic or topics covered, identify the type of task, for example, introductory and state any preliminary knowledge required. This is a valuable resource for teaching Further Mathematics.

Investigating the first Risp on Matrices at the session this certainly would help students with fluency in finding the determinant of a matrix. Rich tasks like this can provide students with a greater understanding than just a traditional exercise and will hopefully stick for longer!

 

Further Mathematics

Some updates to the series of pages on Further Mathematics.
Still a work in progress, but the pages to date are:

I have updated the Teaching Resources page with additional content and am adding additional posts I have written on Further Mathematics.

New pages have been added, see Notes and Examples, Legacy Papers as well as the posts on Calculus, Differential Equations and Linear Programming.

Further Maths – Further Calculus

Further Calculus

Included in the detailed content statements on the material which must be included in A level specifications in further mathematics which makes up approximately 50% of the total content of A level further mathematics, we see the section on Further calculus.

Given that this is a compulsory topic, teachers of Further Maths can usefully look at specimen and practice materials for all the examination boards. We can also use technology to demonstrate and check answers. Additionally there are many useful resources offering notes and examples which are freely available.

WolframAlpha Volumes of Revolution
WolframAlpha can very easily be used to check any volumes of revolution and also gives a clear visualisation of the solid formed; note the option to show the surface or solid formed.

On Dr Frost’s site, Further Calculus can be found here.

CIMT Reduction Formulae

CIMT – Further Calculus

The A Level notes from CIMT include some useful notes, activities and exercises for Further Mathematics, if we look at Chapter 8, Further Calculus in the Further Pure Mathematics section the we see that the chapter includes Volumes of revolution. We also have reduction formulae which is included in the optinal content for AQA, Edexcel and OCR Specification A.

For more notes, examples and exercises, not just for Calculus but many parts of the Further Maths specification, as well as CIMT, try AJ Hobson’s ‘Just the Maths’ or the Helm Project.

HELM Project – Workbook 14, Applications of Integration 1

If you have not come across the HELM Project before, the project was designed to support the mathematical education of engineering students and includes an extensive collection of notes which include very clear worked examples. For easy access to these resources, the HELM Project Workbooks are hosted by Loughborough University’s Mathematics Learning Support Centre. Alternatively, the complete set is hosted by the Open University. To access the Open University resources you will need to create an account (easy and free), this will also give you access to the numerous free online courses.

(For easy reference these notes have been added to the Teaching Resources page for Further Mathematics.)

Improper Integrals University of Pennsylvania

Improper Integrals – University of Pennsylvania

Looking for resources on Improper Integrals, I came across this from the University of Pennsylvania, a clear presentation with worked examples.

Edexcel have a SolutionBank and GeoGebra interactives for their various texts for Maths and Further Maths freely available online. If we look at Core Pure Mathematics Book 2 for example, you can see the various chapter links. These take you to the interactives for each chapter and to full worked solutions for each exercise. Looking at Chapter 4 for example on Volumes of Revolution, we can see two GeoGebra Interactives allowing exploration of volumes of revolution around the x and y axes.

Further Mathematics Mapping Documents

Unlike Mathematics where the subject content is the same for all the examination boards, for Further Mathematics only half of the subject content is compulsory. The core content can be found on pages 7-10. This prescribed subject content can also be seen in my file of Technology Resources for Mathematics and Further Mathematics (still an ongoing project which will be developed further):
maths & further maths technology by content  
Technology Resources

The content of the remaining 50% is not prescribed and has been defined in the specifications from the examination boards who could build from the applied content in A level Mathematics, introduce new applications, or extend further the core content further or any combination of these. With such choice, the specifictions are very varied; from AMSP, we can see a very useful summary of the structure and content of the various specifications.

For any change in specification, I have always found mapping documents helpful, for Further Mathematics where resources are perhaps less plentiful than for Mathematics, then a clear mapping to the legacy specifications can be useful for finding practice questions.

Mapping documents:
These are all very clear and include helpful notes.

  • OCR A scroll all the way down to Teacher Guides for a document mapping new content to the legacy specification
  • OCR B scroll down to Teacher Guides
  • Pearson – GCSE 2017 and GCSE 2008 content mapping. This spreadsheet maps the 2017 specification content for Maths (sheets 1 and 2) and Further Maths (sheets 3 and 4) to the old specification.

For AQA there is a useful summary of the subject content available and on Mohammed Ladak’s ‘MathedUp’ see his A Level Further Maths Takeaway, a wonderful source of exam questions by topic with mark schemes. AQA questions have been used here.

Looking for further questions on core topic such as Proof by Induction I know I can look at sample questions from all the Examination Boards; see Teaching Resources in the Further Maths series of pages.

To take a look at an optional example, earlier this year, teaching Dimensions (MEI) to the Further Mathematicians, having taught legacy M3 before, I did know where to find many questions, but for anyone new to the subject, quickly consulting the mapping document, we can see that the required legacy unit is indeed M3.
OCR B Dimensions
There are many questions available from the old M3 papers. Looking at the other examination boards, I can see that AQA has Dimensions on its first optional application.

AQA Dimensions

AQA Subject Content

So I know I can find Dimensions questions on AQA specimen and practice papers. I can also check MathedUp where we see questions and solutions on Dimensional Analysis.
MathedUp Dimensions Looking at Revise, a video on the subject is available which includes the AQA legacy reference. Challenge and Ans provide examination questions with very clear solutions.
