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.

Women in Mathematics

March 8th 2020 is International Women’s Day.
We’ll start with an image I have shared before that I think still says it all! Thank you, Steve Lomax (Photo courtesy of the wonderful children of Mansfield Green E-ACT Primary, @mgeact  @EducationEACT) who shared this wonderful response to the task ‘Describe a mathematician’…

Some useful references on women in Mathematics:

From Lucy Rycroft-Smith, see this wonderful collection of books about Maths by women. Lucy has chosen 13 books, I like the way she has categorised the books, a book for the artist, for the rebel…. Brilliant – I can see some in there I want!

From the Advanced Mathematics Support Programme, Find ways to encourage girls to study Mathematics. Note the free resources here, including (for girls and boys!) Maths, Opening the door to your future, a leaflet which explores the post-16 maths qualifications available to students, to help them decide which one is best. There is a girls’ participation self-audit resource to review your strategy and identify aspects to develop.

Note too the 30 minute presentation, Why Study Maths, for students and parents/carers which is about the importance of studying maths post-GCSE. It outlines the options available, and provides compelling reasons for choosing to take an advanced maths qualification. Slides and speaker notes are available to download. These resources could be an excellent way of helping Mathemics Departments link curriculum learning to Careers, for all students, helping to meet the Gatsby Benchmark on this. 

And for some History

Mathematical Miscellany #37

Either write a problem on the screen, type it or use the camera to scan a printed or handwritten maths photo and you will get a step by step explanation and any appropriate graphs. Additionally you get similar problems and online video lectures. Several languages are supported.

I like the choice of methods presented; here you can see that a quadratic is solved and you are given the choice of methods for a step by step solution – an easy way for students to compare methods.

Supported problems are as follows:

● Elementary: arithmetic, real, complex numbers, LCM, GCD (HCF), factors, roman numerals
● Pre-Algebra: radicals and exponents, fractions, matrices, determinants
● Algebra: quadratic equations, system of equations, inequalities, rational expressions, linear, quadratic and exponential graphs
● Word problems on maths concepts, number theory, probability, volume, surface area
● Basic Calculus: Summations, Limits, derivatives, integrals
● Statistics: Mean, Median, Mode, Standard Deviation, permutations, combinations

Select the icon in the top left for examples. I was curious about ‘word problems’; given examples are for example ‘Is 21 a prime number?’ and ‘Probability of rolling 1 dice and getting a 2?’

A little more experimenting needed I think, I tried an integration in this app (Android) and also using Photomath. The Microsoft app simply gave me a solution here with no step by step explanation, though it did reference similar problems from a web search; PhotoMath presented a complete explanation of the integration by parts.

A reminder that for a really clear visual representation then WolframAlpha is excellent; the graph is returned with the query. Step by step solutions come with a subscription but the free option is so useful for checking answers and the visual representations mentioned.

I have mentioned the wonderful problem collection on Open Middle before, if you are not familiar with Open Middle do explore these excellent problems; you can read more about the type of problems you will find on the site on the About page. Note you can search by grade using the drop-down menus.

We could try Coordinate Parallelograms:Coordinate Parallelograms

Tim Brzezinski (@Brzezinski_Math) has started a brilliant collection of Open Middle themed problems on GeoGebra. Under Coordinate Geometry you will find his GeoGebra version of the problem.

Algebra KO extract Nicola WhistonI wrote earlier on Knowledge Organisers, Nicola Whiston has started a collection of Knowledge Organisers which follow the White Rose Schemes of Learning, she is sharing the collection here, via Dropbox. These are really attractive and I think will appeal to students; they certainly appeal to me! I have updated that earlier post with Nicola’s resources.


Quanta Magazine have published this wonderful Map of Mathematics, to quote Quanta Magazine:

From simple starting points — Numbers, Shapes, Change — the map branches out into interwoven tendrils of thought. Follow it, and you’ll understand how prime numbers connect to geometry, how symmetries give a handle on questions of infinity.


For very young children, the Department for Education has announced 6 new apps available to improve reading, writing and speaking.

Following a competition to find the best educational apps for parents to engage young children in learning at home, the apps chosen cover activities ranging from interactive story books, handwriting exercises using Artificial Intelligence, and educational video games. The apps are published on the Hungry Little Minds website.

The expert panel who accredited the apps, chaired by Professor Jackie Marsh of the University of Sheffield and appointed by the Department for Education, included children’s digital media consultants, early learning charities and researchers at universities.


 

Pouring and Filling

Checking my blog statistics I noticed some visits to a 2011 post and realised that the links no longer worked, so some years later – an all-new version! Note the brilliant Painted Cube demonstration at the end of this post.

Some excellent watery demonstrations this week:
Depth Time graphs

Depth time graphs of filling different containers. (GeoGebra). Simply select the container you want and the speed of animation, select animate and watch the graph.

From the GeoGrebra resource team, a resource to interpret meanings of different rates of change across a graph that represents the water level in a hot tub.

Volume

From Michigan State University’s Connected Maths Project Student Activities, one of the Grade 7 Activities is Pouring and Filling which provides a great demonstration of relationships between the volumes of pyramids and prisms. We could tip the contents of a cone into the cylinder for example…

Each activity describes the purpose of the activity and has suggested uses, many activities as this does have helpful how to videos.

These activities are well worth exploring, for example in Grade 6 we have factor and product games and also the very satisfying locker problem. Note the TEDEd lesson video here.

Painted CubeOne of the grade 8 activities is the classic Painted Cube. This activity is so clear; it allows students to build a cube or cuboid out of unit cubes, colour the faces using a palette of colours, then rotate the object to paint the initially hidden sides. The expand option allows students to blow up the prism and inspect will count the number of cubes with 0, 1, 2 or 3 painted faces.
