It seems appropriate to start this post with these brilliant March Calendars from Wayne Chadburn.

For a little bit of Maths each day students can use one of these March Calendars. There are calendars available for Foundation, Foundation+ and Higher. All the calendars can be downloaded from the above link. All are designed to be non-calculator calendars. You can check your answers with the solutions provided.

Attending the events will help both teachers and students link maths curriculum learning to careers, thus fulfilling Gatsby Benchmark 4.

4. Linking curriculum learning to careers

All teachers should link curriculum learning with careers. For example, STEM subject teachers should highlight the relevance of STEM subjects for a wide range of future career paths.

There are a wealth of resources on the World Book Day site for children of all ages, including I noticed, good perhaps for reluctant readers, these free podcasts.

For a list of recommended books for young people interested in Mathematics, try this list from Nrich which is grouped into three different categories: History of Mathematics, Recreational and Thinking Mathematically. From Cambridge University this list of interesting mathematics books and internet sites is mainly intended for sixth-formers planning to take a degree in mathematics. The list includes some items which are suitable for less experienced readers so may well appeal to a wider audience. The list was last updated in September 2020. I see it includes Kevin Houston’s “How to Think Like a Mathematician, see also from Kevin Houston his page on the book which includes some solutions to problems in the book, also available are sample chapters on writing mathematics.

For younger students, this revision resource of problems was created for Year 6 (age 10-11) to use on World Book Day.

We could bring books and Mathematics together with some Statistics. UK readers who remember Statistics coursework may remember AQA’s coursework task ‘Read All About It’ where students considered various newspapers and magazines for readability. Similarly, we have Edexcel’s Newspaper Comparisons. A search for these old coursework tasks returned this Edexel document which has numerous investigations with mark schemes; Newspaper comparisons is on page 171. The document is a very useful source of problems and data handling activities.

We could consider the reading age of a text; consider these readability formulae; if you paste some text to this site, Readability Formulasyou can easily check statistics for your chosen text and generate a reading age according to the various tests.

It seems appropriate to check some world records on books!Did you know that the first collection of crossword puzzles was published in the USA in 1924?

Note in particular Colin Foster’s KS3 Instant Maths Ideas (3 books) – a wealth of ideas you can try in the classroom and now freely available online. Colin Fosteris a Reader in Mathematics Education in the Mathematics Education Centre at Loughborough University.

I tried the text of this post for readability – college level!

Students need to be confident in applying the four operations to positive and negative numbers; the image above shows the subject content included in GCSE (age 14-16) Maths specifications. KS3 (age 11-14) students too are required to be fluent with negative numbers.

A look at some resources to develop understanding of operations with positive and negative integers and exercises for practice …

I’ll mention the ‘sign rules’ here as they cause much confusion and many misconceptions, we need to word these so carefully. In fact, we need some more examples to stress we are talking about adjacent like signs. Look at -4−-3 and -4−-6 for example.

From Jonathan Hall, on MathsBot, generate all the addition and subtraction multiple-choice questions you want with his brilliant Directed Number MCQ Generator. I really like the option to have questions using counters of varying relative sizes.

Corbett Maths provides us, as always, with videos and many practice examples. Scroll down the list to Negatives for a set of resources.

On Dr Frost Maths, see the KS3 Negative Number resources, note that the downloadable resource (slides which cover the four operations) and the video can be accessed without signing in.

I like the wording here, students are often confused with sign rules when adding and subtracting positive and negative numbers.

I couldn’t agree more with Siân, it’s always a pleasure listening to Simon Singh as it was listening to all the other great presentations at the February TM Maths Icons Conference. An amazing day – thank you so much @TMMathsIcons.

Not a conventional competition, but to challenge your able mathematicians, try Parallel from Simon Singh. All materials and resources are completely free and teachers will have access to all the student scores from the Parallelograms which are automatically marked.

Students earn points depending on their percentage score on each Parallelogram, which in turn earns mathematical badges. Even before you create an account Even without an account, you can get a taste of what we offer by just clicking on the Parallelograms on the left. Have a look at this parallelogram on Pie Charts and Speed Reading for example.

The references to Simon’s book The Simpsons and Their Mathematical Secrets was a reminder of all the brilliant Maths hidden in The Simpsons. Information for teachers on the book is available, including a PowerPoint presentation for teachers Simon Singh has created, notes are given with the slides.

It was also a reminder that back in 2014 I was honoured to feature a post featuring answers by Simon Singh to my questions.

I enjoyed all the sessions, including Robert Southern on Graphical Transformations.

My own presentation was on the use of Colour in Mathematics and all the slides and some further links referenced in the slides are available on a dedicated page.

The puzzle at the beginning of the post which apparently Bart got before the rather more nerdy Lisa featured in the episode Lisa the Simpson.

The excellentMaths Careerssite is managed and maintained by the Institute of Mathematics and its Applications. If your students wonder where Mathematics is used they will find plenty of answers here. See for example Who employs mathematicians?

Also from Maths Careers, see this post with instructions on how to make this wonderful pair of linked Möbius hearts.

If you wish to get creative and try this I advise watching the Numberphile video carefully; following the instructions worked as you can see from my creation here! I can verify that unless you follow the instruction to make sure the twist in each strip is in a different direction you will end up with a mess! Quite an interesting mess but certainly not two hearts!….

Note the Desmos graphs on my strips. I created a file in Word valentine-mobius-hearts (or pdf: valentine-mobius-hearts) with Desmos images in a table. Adding dotted borders to the table gives guidelines for cutting. I began each cut by using the end of a paperclip to pierce the paper.

To create my strips I printed the document and then printed again on the reverse. I then cut out and trimmed the strips so there was no white space at the end – the picture here has been made using strips 10 cells long.

From the MEI Archives, the February 2015 edition of the MEI Monthly Maths Magazine includes some connections between maths and Valentine’s Day. On page 7 note the article “A Happy Ending” which includes references to some Numberphile videos, Professor Ron Graham discusses the Happy Ending Problem and from Dr Emily Riehl, The Stable Marriage Problem. We also have a great Parametric Heart spreadsheetfrom Think Maths.

This edition of the magazine includes some lovely activities which link paper folding and proof.

This Valentine Relay from Chris Smithis excellent as are all the other relays in this excellent set of resources. You can find more excellent resources from Chris on TES and follow him on Twitter here.
