“Hi Bruno, BBC are in reception for you.”

BBC News Email

Well, there’s an email I didn’t think I’d ever receive. Who could it be and why were they here to see me and not the headteacher? It can be strange what goes through my head. “I’m too young to meet Michael Aspel just yet. Pretty sure I’m not going to …

Making ‘Tri-axes’ in the Woodwork Room

A couple of completed ones.

Trying to picture 3D shapes in your head and ‘spin’ them round for a different view is hard enough for many people. Which is why asking pupils to visualise 3D coordinates from a 2D representation, let alone perform any calculations from them, is even less straightforward. Realising this, my colleague …

I was in a training session today that gave me such a revelation. One of those I-see-the-world-in-a-different-way-now moments – that’s how much it rocked my world. The trainer, Carly Biggam from ARK, set us up in groups of three: one speaker, one listener and one observer. The activity was very …

Classic mistakes brought to you by the Simpsons

LOGO meets Scratch (thanks Blockly and David Wees)

Times Tables Rock Stars


In my year 7 classes at the start of every year, it’s a sad truth that not all of them know their times tables off by heart. By not having this basic building block, problem-solving later on in maths is always going to be light on solving and big on …

Rolling Numbers

At KSA we practise times tables through rolling numbers (call-and-response chanting the times tables while counting off on our fingers as we go). The physical movement combined with the catchy chants help to energise the class, give us the chance to be loud in maths (that’s a good thing) and …
