Freemason's Cipher

Can you work out how to use this code (Freemason's or Pigpen Cipher)?

Pigpen Cipher

Eg. A = a    R = r     S = s    Z = z

Coded letter Coded letter Coded letter Coded letter Coded letter Coded letter Coded letter
Coded letter Coded letter Coded letter Coded letter Coded letter Coded letter Coded letter Coded letter Coded letter Coded letter ?

A symmetric word looks the same in the mirror; like “MOM”. Can you find any words in the Freemason's Cipher which are symmetric? What is the longest one you can find?

  • If you haven't seen it already we have an online Presentation on Code Cracking which introduces pupils to the basic techniques of cracking simple codes. It also encourages pupils to use technology to do a letter frequency analysis of typical English text. The presentation links into our online Code Cracking Exercise which has three levels of difficulty and awards virtual trophies each time a code is cracked.

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...
