Cryptography in Year 5

18th January 2018

As part of our computing curriculum, the Year 5 children transformed into cryptographers for a full day of cryptography (the art of keeping information secret)!  The children explored different codes including semaphore and Morse code and tried communicating using these. Later, they learned about ciphers (secret codes) such as Caesar’s cipher and substitution cipher and challenged each other to decode secret messages. Their day culminated in creating their own secure, secret passwords using a randomised word list and a dice.  This activity helped the children to understand the concept of data security and the importance of passwords for online safety! Well done Year 5!
