I teach Maths to 10 - 13 year old children and these resources are aimed at them! I have also written a book called, "The Aliens have landed and 174 other problems" which is available from either Amazon or The Mathematical Association. It is full of mathematical puzzles. http://members.m-a.org.uk/Shop

This explains how Public Key Cyphers work and includes a problem to solve. Very helpful as part of a code-breaking course. The solution is also provided. Designed for bright 13 year olds and upwards.
