It’s that time of year again – save your money and send your loved ones (or anybody!) a math-o-gram!
..and see also “Make Linked Möbius Hearts“.
Click on the image and move that slider!
Desmos have provided you with the means to send a math-o-gram to the mathematicians in your life!
Valentine’s Day seems an appropriate time to express love for Desmos!
Geeky people you could even use the Desmos API …
Remining with the loving theme you can also express your feelings for WolframAlpha!
Valentine Relay – Chris Smith
For some Valentine class activities, try the Valentine Relay from Chris Smith and note 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.
and here’s a Valentine logic starter from Transum.
For really easy to digest research on Mathematics education from Cambridge Mathematics, see their Espresso page where in their words, “Each month we bring you an Espresso – a small but intense draught of filtered research on mathematics education, expressly designed with teachers in mind. Each Espresso considers one particular issue in mathematics education, and how the latest good-quality research can provide helpful guidance or further reading.”
Note the Research page which includes the link to this excellent site and more references whilst not specific to Mathematics I believe are important to teachers of any subject. Note the resources from Chris Moyse who understands that teachers are busy people!
Exploring Algebra Review Questions from Underground Mathematics I came across some Coordinate Geometry questions I really like and yesterday spending a day with the very talented writing team and my fellow Underground Mathematics Champions we explored Straight Line Pairs, a question with much scope for exploration and possible methods of solution.
The image above has been created from the Printable/supporting materials.
My Year 11s will be looking at Coordinate Geometry this week and I have some other questions I would like them to try. It is possible to create pdf files for a collection of questions, see Saving Favourite Resources, one of Underground Mathematics’ How To Videos. (See the tutorials page I have in the Underground Maths series of pages – a work in progress).
You will find a whole collection of such questions if you look at Geometry of Equations. This includes many resources including Review questions. Note the Building Blocks resources. I think I’ll be using Underground Mathematics resources with ever younger students – Year 9 can try Lots of Lines! You will see from the the supporting materials that this has come from the brilliant Standards Unit (A10) collection. Students must sort the lines into six pairs, each pair matching one of the given descriptions.
Staying with the Building Blocks I do like Straight Lines where students must decide which of 17 equations are equations of a straight line.
Look at the list – a wonderful lesson in not jumping to conclusions here! Both my Year 9 and my Year 11 are going to be trying these this week!
Straight Lines reminded me of Line Pairs, I feel an extension for Year 11 coming on!
Underground Mathematics provides such an outstanding collection of resources that I have begun to create a series of pages on the site. The resources are not only good for Advanced Level but for GCSE students too, particularly for students aiming at the very highest grades. This series of pages is very much a work in progress which I will be updating regularly.
I have used many of the Review questions for my able GCSE students. As you can see from the descriptions of resorce types, the review questions are ideal for the new GCSE specifications as they have been selected to test students’ understanding of one or more topics and to exercise their problem-solving skills. The questions which have been chosen require non-routine thinking. You can browse all the Review questions or narrow your search by question type; note the O/AO-level questions which are questions from old papers. One can also search by line ( Number, Geometry, Algebra, Functions or Calcuus) and by Station.
If you create an account you can easily save and organise your favourite resources. This list of favourites can be easily downloaded as a csv file. To further organise your favourites you can create subcollections.
This too is a work in progress, I will create a collection of resources I believe are particularly useful for GCSE. I have several Algebra favourites so far. This Excel file has hyperlinks to all the resources shown here. algebra-gcse-9-1. Alternatively this pdf file also has the relevant hyperlinks. algebra-gcse-9-1
As more news and documentation has become available for new specifications I have reorganized the A Level Reform series of pages.
Further Maths Supposrt Programme Summary of Changes
With any change of specification I have always found any documents on summaries of the changes and also mapping documents very useful indeed. Clearly much of the content is still on the new specifications and resources we already have can be used again.
With a greater emphasis on modelling and problem solving in both AS and A Level specifications resources such as Underground Maths with its aim of “Enabling all students to explore the connections that underpin mathematics” will be very valuable. This page highlights useful resources.
The Specifications and Support page includes links to the specifications for all the examination boards, including specimen materials. Other supporting documentation and news updates including accredited specifications can be found on this page.
There is also a separate Edexcel page; I recommend signing up to the Mathematics Emporium. I suspect some of those old A Level papers might come in handy!
This is an ongoing project; pages will be regularly updated and new pages added.
To use the links in this post you will need to be logged in to Diagnostic Questions. Create an account if you have not already done so as this site with thousands of high quality diagnostic questions and additional analytical features is free and note the reassurance on the site that Diagnostic Questions are giving “you, the teacher in the classroom, a promise that Diagnostic Questions will always remain free.”
I wrote earlier on the brilliant collections of Diagnostic examination questions available. As well as the various Collections, there is an extensive library of quizzes are available ready for you to use.
It is very simple to create a quiz of your own using the Instant Quiz Facility. The following slideshow shows how I created a quiz on logs and exponentials. To create a new quiz I make sure that the Instant Quiz has no questions currently in it so have got into the habit of clearing it out once I have created a new quiz. The instructions for doing so are included here.
To see the pdf version choose this file: Logs & Exponentials Diagnostic Questions and to view the quiz online then follow this link. I have created several quizzes, some simply to gather question types together; see for example the many questions on Probability and Venn Diagrams.included in this Venn Diagrams collection. I created a quiz of all these questions so I could download the pdf for reference. Included in the Further Resources section on Iterative Methods for Numerical Solution of Equations I have included the whole collection of Trial and Improvement and Iterative Methods diagnostic questions; the complete quiz is here.
Checking Insights for my Year 11 class I can see that students have completed many of the diagnostic examination questions. Two students in particular have been rather busy completing 253 and 484 questions, they both got 9s in their mock examinations! (We used AQA Practice Papers set 3).
There is also a mobile app which students can use to complete quizzes assigned to them by their teacher. Testing this recently it works on both my Android tablet and phone.
Extensive help on Diganostic Questions is available on the site. Clear step by step instructions are given.
2017 Year Game from mathforum.org
It’s that time of year again and we can play the 2017 Year Game in our January lessons.
On Simon Job’s MathsClass, he suggests writing a number sentence under the date; as you can read on his blog he endeavoured to write the number sentence using the digits of the date in order in 2016. It strikes me this idea could be used as a starter, ask the students to come up with such a number sentence.
2017 is a prime number and as we see from the WolframAlpha properties below, in particular a Pythagorean prime, so another source of starters and investigations perhaps? The last time the Year was a Pythagorean prime was 1997.
We can always turn to Number Gossip from Tanya Khovanova for information on properties of a number.
We can also look at WolframAlpha which provides further information including what 2017 looks like in historical numeral forms. We could use the various WolframAlpha queries to learn how Babylonian, for example, numerals work. Some possible starters for January lessons here I think!
The Babylonian system was a positional base 60 system, though interestingly uses ‘units’ and ‘tens’ symbols to create the 59 symbols needed.
For more on the Babylonian system including how fractions were represented see History of Fractions from Nrich.
We should make a calendar for 2017.
Really good if you happen to be teaching Nets. From trol, Teacher Resources on Line.
Wishing educators and students everywhere a very Happy New Year.

The presentation has also been added to my Presentations Series.
I have several references in various places on this blog to some great visualizations.
Time to put them all together!
Jeffrey Ventrella’s Composite Number Tree
From Jeffrey Ventrella this wonderful Composite Number Tree – I have used this successfully with many students. It makes a great starter. Students can work out themselves how the tree is being formed and comment on any patterns they notice.
Stephen Von Worley
Another excellent visualization, animated factorization diagrams comes from Data Pointed. And here is Stephen Von Worley’s blog post, Dance, Factors, Dance which tells the tale of the animation. Noting his reference to Brent Yorgey’s factorization diagrams led me to Brent’s own later post, More factorisation Diagrams. I love Brent’s use of colour here. If you want even more on these great diagrams he has more information and links on this page on his blog, The Math Less Traveled.
Statistics – thinking about large data sets which we will need to for the new A Level specification – for an amusing large data set, how about the Furbles?! The images generated here are from the original 2003 version which is still available on Alec McEachran’s ptolemy.co.uk. Talk to students about summarising this data, perhaps ask for their impressions as to which colour is the most or least common. Data can be presented as a bar chart or a pie chart and you can choose to categorise in various ways. It is also possible to vary the number of Furbles, the maximum and minimum number of eyes and sides. The illustration here show the largest data set possible.
Alec McEachran’s Furbles
Note to get to your chosen Furbles, complete your requirements and press Go!
Alec McEachran – Primitives
Returning to the factorisation theme, note that Alec McEachran’s ptolemy.co.uk is also home to the Primitives application. As you can see from his site, you can read Alec’s article he wrote for the ATM magazine Learning About Primes.
Fawn Nguyen – Visual patterns,
On the subject of Diagrams generally I have several posts on the subject. You can see Fawn Nguyen’s lovely Visual Patterns in Diagrams in Mathematics.
