## Problem solving rules are for fools, says streetfighting mathematician

The New York Times has an interesting Q&A with **Sanjoy Mahajan**, author of *Street-Fighting Mathematics*, that delivers his take on the Gulf Oil spill, and the relationship between stair-climbing and eating jelly doughnuts. Here’s the promo spiel for his book…

In problem solving, as in street fighting, rules are for fools: do whatever works—don’t just stand there! Yet we often fear an unjustified leap even though it may land us on a correct result. Traditional mathematics teaching is largely about solving exactly stated problems exactly, yet life often hands us partly defined problems needing only moderately accurate solutions. This engaging book is an antidote to the rigor mortis brought on by too much mathematical rigor, teaching us how to guess answers without needing a proof or an exact calculation.

Under a business model that makes no sense at all to us, the PDF of his book is also provided for free.

## Maths busking…

…not seriously?

Yep, apparently **Maths busking** is the new thing.

Here’s an article we spotted in the **Guardian**:

## Will mapping Functional Maths teaching onto a GCSE course be a nightmare?

When we set about designing our **AQA Functional Maths series**, this was one of our main concerns: that teachers might struggle to integrate Functional easily into their existing GCSE course.

Indeed, it was a stand-out feature of existing Functional books that they did not lend themselves to integration, as we **posted back in January**. Sure enough, one of our readers raised this issue **earlier this week**.

Actually, it doesn’t have to be that way. This is what we replied to our reader:

We designed our

Functional courseto slide as easily as possible into a GCSE course. Here’s how:

1. The Functional Teacher Guide(due out early next month) contains Schemes of Work mapping the Functional to GCSE.

2. The Functional Student Bookhas been designed with a clear mathematical structure: each chapter is clearly labelled by mathematical topic (ratio, mean & range, probability, etc) so it’s easy to see where and when you might fit a functional lesson into a GCSE course. The maths builds through the book, so students are never asked to tackle topics they haven’t already covered earlier in the book. “Practise the Maths” sections at the start of every chapter provide a chance to recap all key mathematical techniques before tackling Functional questions.

3. The Functional Student Bookmirrors ourGCSE Student Books, so mathematical topics are covered in the same order in both resources.

Hope this helps…

## All About Maths textbooks

It’s interesting to see that AQA have added a ‘textbooks’ tab to their **GCSE** **maths website**** **to help you ‘find and buy resources you need for teaching [the] new Maths qualifications from September’.

## Functional Maths is coming! Subscribe to this blog by 31st August and receive a FREE Student Book…

After a 3 year pilot and much debate, Functional Maths is about to become reality for all schools in the UK.

We expect that teaching Functional will evoke a variety of emotions in Maths teachers (curiosity? excitement? panic?) If it’s the latter, please remember there’s a **survivor’s guide** on this blog. Or click here to go through to the **AQA website**.

And if you’re looking for resources, only one **Student Book** has been published for the new spec… Yes, it’s ours and we’d be delighted to offer a **free copy to any existing or new subscribers to our blog**. Here’s a sneak preview:

**Other features of the Student Book:**

**Practice exam papers at Level 1 and Level 2**, written in accordance with the new spec and the new specimen papers.**Click here for a sample.****“Practice the Maths” sections**at the start of every chapter, offering revision and practice to build students’ confidence. Samples of these can be found in two recent posts: click here for**wind power / formulae**, and here for**school trips / understanding data**.

**How do I obtain my free copy of the Student Book?**

If you’re new to this blog, simply enter your school email address in the box top right and we’ll post a copy to your school address.

## Chameleon explains Maths, tells Pony to shut up

So we had this idea a while back to try and explain the concept of AO2 through the medium of animation. However, somewhere along the line things went a bit skew-ways, and we had to call a halt before the “creative” madness got out of hand. Check out the results…

This is wrong in perhaps many many ways, but we think it’s funny and harmless, so take a look and pass it on if you agree. (Note – turn the sound up)
