• Mrs.Smith, Staffordshire
•
• Every number is a factor of itself and a multiple of itself, so your totals are incorrect!
• Mr Hand's UR Set, The King's School Worcester
•
• Actually Mrs Smith, if you read the question properly, you will see the word "other". Thus meaning numbers being factors and multiples of themselves is totally and utterly irrelevant.
UR Set 7 sincerely hope this clears you misunderstanding.
• Mr Walsh, ASCPS
•
• Aside form the other listed factors, surely 10 is not only a factor of 40, but also a factor of 20? Is that too simple?
• Transum,
•
• How many people are caught out when a number is repeated in the grid above (different numbers appear each time the page is refreshed)? So for example if 47 appears twice you can count both of them as being factors of other numbers in the grid because the first 47 is a factor of the second 47 and the second is a factor of the first!
• Mrs S, St Albans
•
• Shouldn't the number of factors and the number of multiples be the same? If A is a factor of B then B is a multiple of A, and vice versa.
• St Nicolas Junior School, Newbury, Year 5
•
• We like the way the maths is set out however

Note to teacher: Doing this activity once with a class helps students develop strategies. It is only when they do this activity a second time that they will have the opportunity to practise those strategies. That is when the learning is consolidated.

## 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).
