## Multiplying indices

Get the PowerPoint here Again, a lot of stuff is stolen from Jo Morgan’s great work. I mean, I’m never going to make something as beautiful as this. I wrote some questions. I think they’re quite nice. And I put some discussion slides in again

## Index Notation

Download the PowerPoint here. So … I can’t claim that I’ve done much original work here. Most of this is stolen from Jo Morgan’s indices in depth presentation. Sorry Jo! Normally I make a lot of stuff from scratch, but Jo’s work here is so good that I can’t really improve on it. If you… Read More »

Opinions vary. You might think that I’ve structured this waaay too much, and removed too much thinking from the students. It would be interesting to… Read More »

## Pythagoras’ Theorem

Moving on to finding the missing side, no matter if it’s long or short. Something a bit more fun Finishes, as always, with a five quick questions learning… Read More »

I am increasingly into bar modelling for KS3, although I’m still not massively convinced when it comes to negatives. I call these ‘reverse’ ratio problems. I don’t know if that’s the correct terminology. I have been… Read More »

## Sharing in a ratio

There’s some LOVELY questions in the White Rose Barvember stuff. This lesson has an example problem pair and some mini-whiteboard work. When I taught this lesson,… Read More »

## Queer Eye’s Mathematical Mishap

On an episode of Queer Eye, a family of 3 was about to become a family of 4.
