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

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.

Math with Bad Drawings

I had been tutoring the wonderful Betsy for five years. When the day came for our last ever session together before the end of her Year 13, I received this beautiful book as a gift of appreciation.

This a very readable book by Ben Orlin. I'm really enjoying the humour in the writing and the drawings are great.

Ben Orlin answers maths' three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that mathematics should belong to everyone.
