Cryptography was incredibly important during WWII because of the British wanting to communicate without the risk of interception by the Germans. They would talk over the radio using a code, that could then be deciphered with a cryptograph.
In Year 3 today, we wrote and solved our own secret words and messages using a cryptograph to decode them. We applied our maths skills to write and solve problems and then found what letter the number matched up with in the cryptograph.
