## Algebra Tiles- from counting to completing the square

I have become increasingly interested in visual models recently as a way of introducing topics. Visual models have the power to illustrate concepts in their rawest, simplest form without the misleading associations that words and abstract notation can introduce. I’m convinced concrete/visual model introductions should form an increased part of my practice, but the question that interests me is which visual models...

## “Table of coordinates” rather than “table of values”?

A very simple idea this one… I walked into a colleague’s class the other day to see her teaching a first-lesson on straight line graphs. She’d called the table of values a table of coordinates instead. I thought this was a simple idea, but one which seemed to make more sense to the students, many of whom are low-attainers at present,...

## At GCSE you’re really only ever doing one of 9 things with algebra…

I want my current year 10 and 11 classes to appreciate the big picture with algebra. They need to see, that despite the large number of skills we teach them, they are only ever working towards doing one of nine things. Here’s an idea: Click here to download

## G&T website shout out: IB Maths, ToK, IGCSE and IB Resources

I got an email from a reader, Andrew Chambers drawing my attention to a website he has built for IB students studying in Thailand. The content they study is generally equivalent to A-level.

## Numberphile- videos about numbers and stuff

Numberphile.com is a website your pupils simply must know about. It describes itself as “videos about numbers and stuff” which is a pretty good summary in my opinion. The videos are not tutorial skill-based offerings, but engaging adventures into interesting mathematical concepts and problems. I really like them as they show maths at its best: interesting problems and fascinating results, rather than...
