• 10a1, Willenhall School
•
• The question says through TO the back cover. This implies that he does not eat the back cover! The answer should be 28.2cm.
• Transum,
•
• Thanks to all the good people in Year 10 at the Willenhall School for pointing that our. The words 'and including' have now been added to the question.
Incidently the number of volumes in the Transum Encyclopedia and the thickness of the pages changes each time this page is refreshed so it'll be a different answer next time you visit.
• Teacher Of 10a1, Willenhall School
•
• My class will be really pleased to see this! This is a great starter for revising decimals and getting students to think functionally. Thanks!
• Class 8b2, Birkdale High School
•
• Oops - we all need to remember to read the question - even Miss!
Thanks - we enjoyed this one!

[Transum: The surprising answer and explanation appear below but only for teachers who have signed in. You can find out more about creating a teacher account here.]
• Stefanie Lehmann,
•
• Surely each book in the middle has got a front and back cover to eat through.

[Transum: That's right Stefanie. But that's only part of the way to finding the correct answer to this problem]

## 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...

 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).
