Codes & Ciphers Maths Resources for Teachers

Codes & Ciphers

These mathematics resources were produced by the Centre for Innovation in Mathematics Teaching in collaboration with Bletchley Park National Codes Centre and other related organizations. You can view an introduction to the resources written by the authors here. There is a file describing links with the Mathematics National Curriculum here.

The Key Stage for each of the 20 modules is indicated in the download table. Specific Year targets are to be found at the top of the first page of the Teacher Resources for each module. The last three modules (asterisked) are specially targeted at gifted & talented students.

If you would like to make any comments about these resources, then please e-mail us at education@bletchleypark.org.uk.

The development of these resources was made possible by the financial support of the Gatsby Foundation and Gatsby Technical Education Projects (GTEP).
