Modelling in maths

I’ve come to the conclusion that ace teachers are experts in classroom culture and that the most effective maths teachers are also excellent at modelling and questioning.

We can learn about maths teaching from Shanghai

My interest in Shanghai maths teaching is an intellectual matter not a political one. We should definitely be wanting to know more about their pedagogy given we are rarely in a position in our busy, chaotic, highly emotional school lives to engage with it. They’re the ones who have the …

How we teach addition & subtraction of negative numbers

Notoriously difficult for pupils to understand, I think addition and subtraction of negatives is one of the things that one comes to understand after doing lots of practice. HOWEVER, that practice needs to be yielding correct answers from the off. It’s no good sending pupils off to do lots of …

ClassBadges.com – Marking and rewarding progress

When we started blended learning, life was good. My pupils began studying more independently and their work rate went up but it didn’t take me long to realise there was something missing to sustain their productivity – they needed their efforts to be recognised more than before. Having had a …

Mean Paper Aeroplanes

Today we threw paper aeroplanes in my year 7 lessons and it was a lot of fun! Underlying all the fun, however, was a serious competition and competitions must have winners. To win fairly you probably need to throw more than once to account for variances in skill, luck and …

Chromebooks are not just for Christmas

On the back of my Time-Shifted Teaching trial last year, we’re going ahead with a larger scale pilot of blended learning this year. I found that there were a number of barriers to time-shifted teaching, including pupils’ access to computers at home. A chance discussion with ARK (the multi-academy network …

What has Jo Boaler got to do with it? [Maths at KSA, that is.]

At KSA, we teach maths in mixed ability groups all the way through Keystage 3 (ages 11-14) and I now think it’s one of the smartest decisions we ever made. When I was appointed Head of Maths, before the school even opened, the Headteacher asked me How do you feel …

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

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 …

Classic mistakes brought to you by the Simpsons

Here’s how I see it, it’s easier to learn from the maths mistakes of others than from your own. Probably because there’s an emotional association with making a mistake, I find pupils jump at the chance to dissect and discuss the root of misconceptions of others, and by others I …
