This unplugged activity from the CS4FN team uses two examples – an insulting computer and one that can play snap – to look at simple computer programming, flow of control and logic. Everything is provided for this front-of-class activity, which would act as an effective starter for a lesson on programming concepts...

This resource is designed as an introduction to activities available using a Raspberry Pi computer. The introduction explains:
*what a Raspberry Pi is: a small, affordable yet powerful computer
*what can be learnt from this manual: how to perform simple programming and the basics of computer science...

Containing two linked activities, these resources from the CS4FN team introduce graphs to represent inter-related data and algorithms to negotiate them.

Suitable for non-programmers being introduced to algorithms, the two challenges – the Knights Tour and the Tour Guide – are similar. Both use graphs as...
