This resource contains two powerpoints. One goes through how computers have changed over time, from the humble abacus to modern day gaming computers. The other covers some influential people in computer, such as Alan Turing, Charles Babbage, Ada Lovelace and Sir Tim Berners Lee. There is also a worksheet to allow the students to design what they think computers will look like in the future and what they will do. There is also a wall display showing the progression of computers throughout history on a timeline.

A presentation explaining what the Caesar Cipher is, as well as definitions for encryptions and cryptography, and an activity to create cipher dials and encoded messages. Also, a word search with encrypted answers - so the children have to first decrypt the words then find them in the word search. This would work great as a small activity or in addition to a unit of work. It offers a way to add a fun activity to get children engaged in what could be an otherwise boring subject.
