# Secondary Magazine - Issue 127

# Welcome to Issue 127 of the Secondary and FE Magazine

This is a great time of year for real-life-inspired maths lessons: those spherical pumpkins asking to have their volume and surface areas calculated (or something much more ambitious!), the fireworks of Bonfire Night and Diwali prompting questions about projectiles and parabolas, and then some lessons on star polygons to encourage your pupils to be mathematical explorers, to develop their geometrical reasoning, and to leave you knee deep in Christmas classroom decorations. The real world has inspired this month’s magazine too: modelling journeys with bearings, explaining HCFs with tilings, and tying together all sorts of seemingly disparate problems with the thread of proportional reasoning. We share a scheme of work to prepare sixth formers to learn about binomial hypothesis testing, and our roving cameras have found abundances of triangles. Does what’s outside your classroom window sometimes stimulate activity inside? Let us know, by email info@ncetm.org.uk, or @NCETMsecondary on Twitter.

# Contents

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
Getting lost in the autumn mist? We suggest how your pupils can find their bearings.

Sixth Sense
A tree-ish diagram about teaching tree diagrams, and the other pre-requisites for Binomial hypothesis testing.

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 teaching ratio and proportion.

It Stands to Reason
No doubt your pupils can work out the HCF of two integers; but could they draw it for you?

Eyes Down
A picture to give you an idea: triangles everywhere.
