Secondary Magazine Issue 126'Pumpkins!' by Tanya Hart (adapted), some rights reserved

Welcome to Issue 126 of the Secondary and FE Magazine

Falling leaves and sky-rocketing pumpkin prices mean that the end of October is fast approaching: we hope that the first half of the first term has gone smoothly and successfully, and that both you and your pupils are fully into your strides – especially so if you’re in a new post or a new school, and even more especially so if you’re an NQT. If you’re taking stock over the break and have some “what I wish I’d known in September” advice you want to share with us and your peers, please get in touch - email info@ncetm.org.uk, or @NCETMsecondary on Twitter. Do also get in touch if you want to share a picture for the regular “Eyes Down” article: if your picture is published, we’ll send you a £20 voucher.


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. If you ever think that our heads haven’t been up high enough and we seem to have missed something that’s coming soon, do let us know: email info@ncetm.org.uk, or via Twitter, @NCETMsecondary.

Building Bridges
We discuss probability in the context of life expectancy, death rates and actuarial life tables: a little ghoulish, perhaps, but it’s that time of year!

Sixth Sense
Last month’s discussion on factorising cubics and higher order polynomials ended on a cliffhanger; escaping from that peril, we develop the Remainder Theorem and formalise the Factor Theorem.

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: for this issue, the librarian has pulled together research about children’s development of a deep and flexible understanding of mathematical ideas.

It Stands to Reason
You may recall the 80s ITV gameshow classic “Catchphrase” with the host’s own catchphrase (how very meta…) “say what you see”: good advice if you wanted to win the star prize sandwich toaster, but also an excellent strategy to help your pupils develop their ability to imagine rotations, and other transformations, and thereby strengthen their geometrical, and wider mathematical, reasoning. This month’s article explores further the ideas and strategies introduced in the previous issue.

Eyes Down
A picture to give you an idea: an example of conceptual variation 'live' in the classroom.
