Secondary Magazine Issue 125'Autumn Leaves' by Mike Mozart (adapted), some rights reserved
 

Welcome to Issue 125 of the Secondary and FE Magazine

Welcome to autumn, and to the realisation that half of a half-term has already passed us by. What happened to September? Anyway, this month we have much for you to chew on while the leaves start to fall. The mix includes imagining geometric rotations, factorising cubics, teaching trigonometry without resorting to SOHCAHTOA, and trying to re-shape the diet offered to GCSE re-sit students. As always, your comments and feedback are very welcome, either at the bottom of the page, by email to info@ncetm.org.uk, or @NCETMsecondary on Twitter.

Heads Up
Here you will find a checklist of some of the recent, or still current, mathematical events featured in the news, by the media or on the internet: if you want a “heads up” on what to read, watch or do in the next couple of weeks or so, it’s here. This month there is news about two BBC programmes with a mathematical theme, and still available on iPlayer, a free workshop for maths teachers at the Royal Institution, a few places left on our free courses developing PD Leads specialising in A level maths, and a suggestion that you look at our new materials to assess primary (yes, primary) pupils’ depth of mathematical understanding.

Building Bridges
A bridge of a slightly different sort this month. With many of you sure to be handling Year 12, or FE College, re-sit GCSE classes, we present some ideas of how to build a bridge from pre to post-16 study of GCSE maths.

Sixth Sense
One of the key skills we need to help Year 12 pure mathematicians acquire is factorising cubic expressions. We suggest a step-by-step approach to this teaching and learning task.

From the Library
Want to draw on maths research in your teaching but don’t have time to hunker down in the library? Don’t worry, we’ve hunkered for you: in this issue, we draw together research relating to the teaching (conceptual and procedural) of trigonometry.

It Stands to Reason
Developing pupils’ ability to imagine rotations, and other transformations, not only increases their chances of tackling geometry questions. It can strengthen their all-round powers of mathematical reasoning as well.

Eyes Down
A picture to give you an idea: this month, three classroom snapshots to demonstrate how the simplest and cheapest of resources we have lying around our homes or classrooms can often prove powerful aids to understanding. And if this reminds you of Blue Peter, you’re definitely not the baby of the department!
