Code-Breakers is extremely easy for teachers and teaching assistants to use, requiring very little in the way of advance preparation. It is provided in the form of daily 10-15-minute sessions, which enable teachers to deliver the synthetic phonics in a logical and enjoyable way.
OVERVIEW. Students will discover the history of code breaking and its significance on events such as the Cuban missile crisis. They will be able to learn how code breaking works, and create their own codes. The lesson will enable students to consider the moral dilemmas of code breakers. The class will examine code breakers’ legacy.

For centuries some people, organisations and governments have wanted to send information secretly. Different ways of sending a secret message have been developed over time but the most common practice has been to hide information by using a code or a cipher (see box below). Just as people want to keep their messages to some people secret others wan...
Code: A way of keeping the meaning of a message hidden by changing whole words e.g. a series of dots and dashes replace letters and words or at sea flags might be used to replace words and sentences. Encoded: A message that has been put into code Cipher: Relies on hiding a message by jumbling up individual letter of the message Encryption: Sending ...
In the field of secret communications (cryptography), a code refers to a way of keeping the meaning of a message hidden by changing whole words. For example, during the Second World War the word “DYNAMO” was used by the Allies when referring to the operation to rescue troops from Dunkirk beach. In contrast, a cipher relies on hiding a message by ju...
In the First World War or Great War, as well as more traditional methods such as carrier pigeon, millions of messages were sent using the modern technology of radio broadcasts and electric telegraph. Radio waves and electric circuits were used because messages could be sent over long distances in a matter of seconds unlike someone sending a paper m...
In 1909, the British government created the Secret Intelligence Service (or Bureau as it was known for a while) SIS, was engaged in all areas of intelligence gathering, codebreaking and analysis of information. Also, during the First World War the Army and the Navy both had their own Intelligence units that intercepted and decrypted messages. After...
The Enigma machine was invented by a German engineer Arthur Scherbius shortly after WW1 The machine (of which a number of varying types were produced) resembled a typewriter. It had a lamp board above the keys with a lamp for each letter. The operator pressed the key for the plaintext letter of the message and the enciphered letter lit up on the la...
Based on the information presented by the Poles, British mathematician Alan Turing developed a machine that was capable of recovering the key settings. The machine was called Bombe (later: Turing-Welchman Bombe) and was built by the British Tabulating Machine Company (BTM) in Letchworth, Hertfordshire (UK) under supervision of Harold (Doc) Keen. Th...
All across the UK were bases called ‘Y’ stations. The ‘Y’ name came from the shape of the aerial and that was what made it significant. A ‘Y’ station would be listening in to the many radio messages that were sent out across the airways. Some listened to actual voice messages but the majority were there to pick up the encrypted messages being sent ...
When Bletchley was first established in 1938 only a few hundred people were based there, but that number grew as time went on. By January 1945, 10,000 people worked at Bletchley, three quarters of them were women. The whole place operated on a shift pattern so that it was able to operate 24 hours a day. The people there including the women worked a...
When people think of conflicts and war they usually think of armies going off to war and although gaining information, (intelligence) has always been important it wasn’t always perceived as being as important as the actual fighting. However, the Second World War changed that. The Nazis dominance in Europe, coupled with the rise in technology meant ...
Codebreakers. This article for Primary and Secondary teachers is all about the mathematics behind solving puzzles, unravelling mysteries and breaking codes. For students, we hope that the tasks we have selected are intriguing and spark their curiosity.

May 3, 2021 · The Four Resources Model places an emphasis on the development of the four major learner roles. These are Code-Breaker, Text Participant, Text User and Text Analyst (Freebody and Luke, 1990). In order to assume a learner role, the learner needs to focus on the corresponding literacy practices.
