Last year I was lucky enough to go to one of my local MathsHub’s Secondary Curriculum Development sessions which Debbie Morgan, the NCETM director of primary was leading.

I really enjoyed this session and now the NCETM have helpfully put up a video of a similar session online. Even though it is targeted at primary I think it is definitely worth a watch by secondary teachers.

Here are some points, that I feel are important, made in the video.

Planning and Workload

A mastery approach requires one very good lesson; you shouldn’t be planning loads of different lessons as a way of differentiating. She also said that there is no point writing 32 “next steps” in books as the next step in a mastery approach is just the next lesson.

Shanghai Maths and Rules

Shanghai maths is about rules but it isn’t about rules without reason. Memorising things after understanding something leads to more secure learning. Shanghai students are asked to give answers in full sentences such as “The whole is divided in to 4 equal parts, one of those parts is one quarter and so the shaded portion of the circle is one quarter.”These sentences are useful as they get students used to taking and understanding the mathematics – it gives a “context to hang the mathematics on”.

Variation Theory

Debbie talks about this example from Mike Askew’s book “Transforming Primary Mathematics” and discusses the differences between the two sets of questions. Set A is good for promoting just an algorithmic approach to subtraction, but set B (which contains exactly the same questions ) is ordered in such a way to promote students engaging with some mathematical reasoning. I don’t think Variation theory is talked about enough to be honest – I know I should think about it more when designing questions for my classes. 

I studied for my PhD at the University of Nottingham in the School of Mathematical Sciences and there was lots of discussion about women in mathematics whilst I was there.

As a department they are very supportive of female mathematicians and assisting them in building careers in mathematics. They have a bi-weekly meeting for all female members of staff and postgraduates.

Recently they have produced a series of 13 videos – Women in Maths – that feature some of my friends / ex-colleagues as well as people who have started in the department since I left. I think some of these videos have some very inspirational messages about mathematics and the enjoyment of mathematics. They would make great short videos to show to all sixth form mathematicians (not just the female ones!)

I have embedded a few of them below:

I particularly like the following quote from Susanne Pumpluen

“It’s as creative as if you would do arts or music and people don’t see it because it’s often, unless you have a very good math teacher at secondary school, it’s very hidden that it can be so creative and fulfilling”

You can watch the whole playlist of 13 videos here.

I recently received my IMA member’s magazine “Mathematics Today” in the post and in this issue there is a very interesting article by Claire Baldwin, Sue de Pomerai and Cathy Smith titled “The Participation of Girls in Further Mathematics“. Luckily they have made this article available online here so if you aren’t a member of the IMA I’d encourage you to read it now.

This article draws heavily on a literature review, “Gender and participation in mathematics and further mathematics A Levels: a literature review for the Further Mathematics Support Programme” prepared by Cathy Smith and a subsequent report detailing 5 case studies authored by Cathy Smith and Jennie Golding titled “Gender and participation in Mathematics and Further Mathematics: Interim report for the Further MathematicsSupport Programme“. If you are interested in gender and the take-up of A Level mathematics I would encourage you to read them.

I think most teachers of A-Level mathematics would love to have more girls continue mathematics and in particular continue their study into Further Mathematics, I think it is important that we do everything we can to encourage this. About 20% of both my Year 12 and Year 13 classes are female and I am glad that there are female peers in these classes.

From the IMA article I particularly liked the 4 reasons they gave for Further Mathematics being valuable:

• The increased time spent engaging with mathematics and developing greater fluency.
• The study of important topics in pure mathematics not covered at A-Level, such as complex numbers and matrices, that are essential for anyone going on to study maths, physics or engineering.
• The opportunity to study a broader range of applications of mathematics.
• The development of increased confidence and resilience in tackling demanding mathematical problems.

These four things very nicely sum up why Further Maths is such a good qualification.

Despite a significant increase in participation for further mathematics in general, the proportion of girls taking the qualification has stayed broadly consistent with significantly less girls taking the subject than boys. I wasn’t aware that the situation was different in the US, where participation is roughly equal at similar level optional calculus courses.

One of the interventions highlighted in the case studies to increase participation at A-Level was the provision of extra courses alongside GCSE for the high attaining students. This is a concern to me, as anecdotally I have heard of many people stopping the provision of these with the introduction of the more demanding GCSE syllabi – I think this is a shame as the AQA Level certificate in Further Mathematics is a really nice qualification.

I believe we need to do everything we can in schools to encourage students to take A-Level Mathematics and Further Mathematics. What do you do to encourage participation?

The day before yesterday I wrote a post entitled “FP1 Multiple Choice Revision Quizzes” where I shared some multiple choice quizzes that I used last year with my FP1 class and marked using the QuickKey app for iOS.

At first I was quite sceptical about how good this scanning app would be when used with actual student responses, but after a few teething problems I have become very impressed with it.

To use QuickKey you need to register for an account and then use one of their answer sheets for students to record their answers to multiple choice questions on. They look like this: 

As you can see each question has 5 possible solutions (so bear this in mind when writing your quiz – there is no point in having 6 well thought through possibilities!). Each student fills in their student ID (4 numbers) and shades in the correct ovals – this enables the QuickKey app to work out who’s solutions it is scanning.

QuickKey have produced a useful infographic as a guide to scanning the quizzes which I have pasted below and is available here.

This covers almost all of the issues I had when I first started using the app. Overhead lighting seems especially problematic and scanning definitely works best in natural light. I would personally avoid using pencils and emphasise to your students that they should carefully shade in ALL of the oval corresponding to what they thought was the correct answer – this will eliminate many issues and mean that you don’t spend time manually inputting results.

The app syncs nicely with the online QuickKey account, from where you can download spreadsheets and analyse class performance.

In July 2015 William Emeny (@Maths_Master) posted about a diagnostic test he had performed on his Year 7 cohort which took advantage of QuickKey to quickly obtain responses to 90 questions for all of the cohort. This is a fantastic use of the power of QuickKey and we did this with some of the classes last year. I am hoping to do the same test again this year with our current Year 7s.

I’d encourage everyone to give QuickKey a go if they are ever using multiple choice tests.

Yesterday morning I woke up fairly early with baby Jessica (there was quite a pretty sunrise however) and I read “Modelling in Maths“, a great blog post by Bruno Reddy (@MrReddyMaths). In this post he discusses what he tries to do “consistently with modelling” in his classroom.

This is a pretty short post but it is packed with useful tips on topics as varied as questioning, example design, structuring of class practise and the isolation of tricky steps before putting steps together. I genuinely think this post should be required reading for trainee teachers (and others really) as it prompts so much critical thinking about your own practise.

It has definitely made me think about where I need to improve with consistency. I try to think carefully about the examples I use and how I structure a lesson but recently it has been all too easy to let things get in the way of this. Having a new baby, observation lessons to think about, data points to complete and all the other associated admin that goes with being a teacher have been too much of a distraction really and this does affect the quality of my lessons. For example, with one of my classes we were looking at the quadratic formula and I know that correctly evaluating the discriminant is often a cause of mistakes, but I didn’t practise this independently first. When I have taught this topic before I have done this step separately before using the whole formula in one go and I know this works better. So, for me, there is no excuse for me not having proceeded in this way – I just let my thinking time before the lesson get distracted by other less important things.

I need to fight against this!!

Last year I experimented with multiple choice revision quizzes for my Year 12 further mathematics class in the half term before Easter.

I’m not teaching FP1 this year so thought I would make them available for anyone to use. The students seemed surprised at how long it took them to figure out some of the solutions. Each quiz has 5 questions, as shown below, with each question having a choice of 5 answers.

All  5 quizzes can be downloaded from the links below:

1. FP1 Quiz 1
2. FP1 Quiz 2
3. FP1 Quiz 3
4. FP1 Quiz 4
5. FP1 Quiz 5

To mark them I used the QuickKey App which I was actually quite impressed with. Come back tomorrow to read about QuickKey!

I’m a little over halfway with the @staffrm #29daysofwriting challenge

Yesterday I was puzzled to see lots of “Halfway” posts as to me a half of 29 is 14.5 and so surely if we only allow full days halfway would round to day 15… Anyway I liked the idea of answering some of the same questions as everyone else so here are my responses.

Why are you doing the challenge?

Why not?! I quite fancy a mug and last summer I was one of the people to complete the #summerblogchallenge (as was @missnorledge ) so 29 days seemed quite doable, especially with the 29 minute rule

Where and when do you post?

Generally at home once I have done Jessica’s (my daughter) bath and bedtime things.

What have you enjoyed the most about taking part?

I’ve enjoyed having something to motivate me to share ideas and my thoughts – sometimes it can be very hard to find time to do this after a busy day at work. I’ve also enjoyed reading lots of posts about a wide range of subjects that I wouldn’t have necessarily come across on Twitter without coming on staffrm.

What have you least enjoyed about taking part?

I’m not a fan of the simplistic editor provided by staffrm! I’m used to the more sophisticated  editor on my WordPress site where I can include LaTeX, code snippets, use lists etc. Later on in the challenge I may have to resort to handwriting some posts and having my staffrm post consist almost entirely of pictures, or have the staffrm post just provide a link to the post on my own website.

Have you picked up any ideas?

I wouldn’t say I have picked up any concrete ideas but many posts (especially ones by @missnorledge , @mrbenward , @towens , @becskar ) have been thought provoking and given me lots to think about.

Only a very short post today as it is Valentines day and I want to devote my time to my family.

I have put up on my website a Geogebra file that allows you to view 2 heart-shaped parametric curves. Which do you prefer?

The original Geogebra file is also available for download here.

Desmos have also produced some cool Math-o-grams including this very cool heart inspired Sierpinski triangle! I particularly like that you can see the underlying equations.

In December last year I had a review of the MEI/Sigma Network’s game published in the IMA magazine Mathematics Today. I later published an expanded review on my blog in December. Check it out if you haven’t already. 

Richard started  by talking about himself and saying that his first experience with computers was when he was bought a ZX81 for Christmas in 1982. As an aside my first experience with computers was on a BBC Micro at primary school. Richard explained how programming increased his enjoyment of mathematics – an experience that certainly resonates with me. 

Richard completed a PhD at Warwick and after lecturing for a while became involved with the Further Maths Support Programme, before in 2014 taking a job at MEI developing online resources for teaching and learning maths.

There are many great reasons why games are good medium for learning mathematics, Richard highlighted that when gaming you expect to make mistakes and it creates a non-threatening environment for students to try things out. He also highlighted the reasons shown below: 

 What does a good maths game look like?! Richard’s criteria are these

• Encourage students to practise lots of examples
• Provide a representation of mathematical problems in a more accessible way.
• Have a mechanic which has a “physical” connection to the mathematical idea.
• Give players lots of choice about what they can do at any given moment.

If you look on the App Store the vast majority of maths games fall into the first category, promoting practise of key skills such as multiplication facts, basic numeracy etc. 

I hadn’t seen Keith Devlin’s game Wuzzit Trouble before (even though I had heard about it) – I feel that I need to investigate this some more now. Richard also completed a secondment developing some games as a consultant to Manga High and he discussed some of the games he helped develop while there including Ice Ice Maybe and Algebra Meltdown – again Manga High is something I really should explore more..

It was fascinating to hear about the development of Sumaze and how it developed out of this initial idea which Richard felt didn’t have enough variety as a game: 

 Following this he began to consider the idea of moving through squares to get to a target value as a way of teaching something, specifically he looked at developing some of the ideas that led to the logarithm levels in the online version of Sumaze.

The Sigma network then funded the production of a web-based version covering more mathematical topics and for an App version. To develop the app a maths startup company MathsCraft was engaged to provide the graphics, sound and menu version. 

I hadn’t thought too much about the game mechanics before so it was nice to be told a bit more about that. Specifically only nested expressions with only one variable are permitted and so the game can’t test things such as \(x^3+6x\) or \(log(xy) = log(x)+log(y)\). Richard explained that the decision was made to not include things like memory blocks or multiple blocks which would have allowed this kind of thing as it would detract from the gameplay. I think this was probably the right decision – the inclusion of these would have made the game seem a lot harder to play, and probably not add too much in terms of mathematics. 

Richard then talked about the mathematics underlying a couple of the levels:

Negatives 13 -Gridlock Here, if you think mathematically you need to find the fixed point of the function \(f(x) = -3(x+12)\) to get the correct value once you have passed through all the modifier blocks. I certainly hadn’t thought of it like this when I played this level.  

 
 Powers 10 – Binary Finery Here the level is asking you to find the binary representation of 61. 
 
As of 8th February 2016 Sumaze has had over 17,000 downloads since the 20th October and another version dealing with lower level numeracy topics is planned.

There was a very good question about the game mechanic versus the conventional order of operations. For example the operations are applied consecutively and don’t follow the conventional rules, for example in Sumaze 3 + 2 multiplied by 3 would give 15 as opposed to 9. I, like Richard hadn’t considered this before as I had seen the blocks as functions that are applied to an input but I guess this could be an issue for students. What do you think? 

Some people on staffrm may not know that I host the #mathsjournalclub discussions on Twitter. In these some of us discuss a research paper (normally chosen by an open public poll) on a mathematics education topic. The summaries of the discussions of three recent discussions are available here (I still have one to put online!):

• Discussion 1 – A glimpse into students understanding of functions
• Discussion 2 – Mathematical études: embedding opportunities for developing procedural fluency within rich mathematical contexts
• Discussion 4 – ATM MT Assessment Special

With one thing and another I didn’t get a poll up to choose the next article – I’m really sorry about this and this way of choosing articles will return so please send me any recommendations, ensuring that they are open access and not behind paywalls.

However, I don’t want to go too long without having a #mathsjournalclub chat and so I have picked an article that i think everyone will enjoy reading. The first page is shown below

The article is by John Mason, Hélia Oliviera and Ana Maria Boavida and entitled “Reasoning Reasonably in Mathematics“. In this article they discuss some student responses to the Magic Square task, for example the one shown here

I found this article fascinating, especially after seeing John Mason speak towards the end of last year, and I am sure you will too.

I propose that we chat about this on Monday the 11th April at 8pm which is the usual time. I very much hope that you can join me.

The discussion after that will be based on an article that has been voted for 🙂
