2012 marks the centenary of the birth of Alan Turing and yesterday I suggested the following idea to our History and Maths departments. In January we will be going to Bletchley Park for a combined History / Maths / ICT trip and I thought that a good follow up project would be to transform one of our mobile classrooms into a Bletchely Park codebreaker’s hut. We could then recruit a team of ‘codebreakers’ from amongst the pupils. Each break time we could send them a series of coded messages (via email or Twitter?) for them to crack and then resend. As the children crack the codes we would then change them to give them new challenges. We could possibly have two teams – one team sending messages and the other trying to intercept and decode them.
