• At first the starter was challenging but then it started to make sense and that was when everyone started to get the hang of it. All together we got all the answers between us. The people who got the first answer were Danny, Ryan, David, Murran, Molly, Bryony, Alicia and sir. And some others got the rest of the answers.

• A good starter that can be developed easily into a differentiated lesson. For example, use the minumum number of stamps, pairs of stamp values that work for all postage values (1p stamp not allowed!). What sort of pairs work for the fewest values of postage.
• Set 1 Year 4(Mathematical Whizz Kids! ), Banks Lane Junior School
•
• We found three ways to solve this problem by working systematically using multiples of 3 and 8.
(2x8p)+(19x3p)
(5x8p)+(11x3p)
(8x8p)+(3x3p).

• This is an old idea but still very worthwhile even though the cost of the stamps probably isn't very realistic at today's prices. It lends itself to be extended in a number of ways in addition to those suggested by N Cox above (thanks). Please share any ways of developing this activity that might be useful to other teachers.

## Have you read Craig's book yet?

Craig Barton must surely be the voice of Mathematics teachers in the UK. His wonderful podcasts interviewing the industry experts have culminated in this wonderful book. As Craig says: "I genuinely believe I have never taught mathematics better, and my students have never learned more. I just wish I had known all of this twelve years ago..." more...

"How I wish I'd taught Maths" is an extraordinary and important book. Part guide to research, part memoir, part survival handbook, it’s a wonderfully accessible guide to the latest research on teaching mathematics, presented in a disarmingly honest and readable way. I know of no other book that presents as much usable research evidence on the dos and don’ts of mathematics teaching in such a clear and practical way. No matter how long you have been doing it, if you teach mathematics—from primary school to university—this book is for you." Dylan Wiliam, Emeritus Professor of Educational Assessment, UCL.

## Casio Classwiz Calculator

There is currently a lot of talk about this new calculator being the best in its price range for use in the Maths classroom. The new ClassWiz features a high-resolution display making it easier to view numerical formulas and symbols but it isn't a graphical calculator as such (it has the capacity to draw graphs on your smart phone or tablet, via a scannable QR code and an app).

As well as basic spreadsheet mode and an equation solving feature you also get the ability to solve quadratic, cubic or quartic polynomial inequalities and the answer is given just as it should be written down, using the correct inequality symbols!

This calculator has a high-performance processor and twice the memory of previous models ensuring speedy operation and superior computational power.more...

## Hello World

You are buying a (driverless) car. One vehicle is programmed to save as many lives as possible in a collision. Another promises to prioritize the lives of its passengers. Which do you choose?

Welcome to the age of the algorithm, the story of a not-too-distant future where machines rule supreme, making important decisions – in healthcare, transport, finance, security, what we watch, where we go even who we send to prison. So how much should we rely on them? What kind of future do we want?

Hannah Fry takes us on a tour of the good, the bad and the downright ugly of the algorithms that surround us. In Hello World she lifts the lid on their inner workings, demonstrates their power, exposes their limitations, and examines whether they really are an improvement on the humans they are replacing.

 Teacher, do your students have access to computers?Do they have iPads or Laptops in Lessons? Whether your students each have a TabletPC, a Surface or a Mac, this activity lends itself to eLearning (Engaged Learning).
