This year I've written a number of posts about maths textbooks from the last 300 years. Buying and reading historical maths textbooks has fast become my favourite hobby - it's fascinating, and it has done a lot for developing my subject knowledge this year.
Subject knowledge for maths teachers isn't just about being able to do the maths - that's the easy bit - it's also about knowing how to

1. World Cup Box Plots
Thanks to Southborough Maths (@Mathsteam1) for sharing these box plots created by @johnwmillr. They show the distributions of height by position for players in the World Cup. They make for great discussions with students, and provide a nice demonstration of
I was very fortunate to have the opportunity to present at two excellent maths conferences over the last few days. On Saturday I was at La Salle’s #mathsconf15 in Manchester, and on Monday I was at the JustMaths conference at Alton Towers. I did a three night round trip, travelling by train with a huge backpack.
I used to publish very detailed write ups of every maths conference I attended - in

1. Probability Task
Thanks to John Rowe (@MrJohnRowe) for sharing this challenging probability puzzle. If you like this then you'll find similar tasks for a wide range of topics on the fantastic website openmiddle.com which I've blogged about before.
2. Exam Wrapper
Following on from my previous two posts about breakfast warm up activities, I have now published the final set of resources here (Set B):
Breakfast GCSE Warm Ups - Calculator
As with the last set, there are two levels for Foundation and two levels for Higher. Each sheet contains 20 quick questions which I've not numbered so that students can work on them in any order. I hope these help students
The topic 'Highest Common Factor and Lowest Common Multiple' is one where there's a lot of scope for subject knowledge development. There is so much for both teachers and students to explore in this topic. Ask a group of maths teachers how they find the highest common factor of two numbers and I expect a number of different methods will be mentioned. There is no universally accepted 'best way'. I
I was really chuffed when loads of people told me that they used my non calculator breakfast revision resources last week. Although I collate and share a lot of resources, I don't often make my own (because it's ridiculously time consuming!) so I'm glad it was worth the effort. We used them with our 240 Year 11s at my school and they worked well.

1. Boss Maths
BossMaths.com is a great maths website that I haven't seen before. It has over 200 lessons matched to GCSE specification references, each with examples, escalating practice exercises, misconceptions, and exam-style problems. Some topics also have worked example
Year 11s have already gone off on study leave at many schools, but I still have my lovely Year 11 class in lessons (when they're not in exams) and revision sessions. At this time of year I stop my structured topic-based revision lessons and instead use mixed topic resources like these Higher GCSE workouts. These workouts take a full lesson and consolidate a wide range of key skills, with the

1. Show That
These mixed topic 'show that' questions created by Josh Evans (@JevansMaths) and adapted by Catriona Shearer (@Cshearer41) are useful for revision. GCSE students often struggle to understand what is required in a 'show that' question. See Josh's tweet and Catriona's
