This unplugged activity, from the CS4FN team at Queen Mary University of London, helps learners to understand variable assignment and operations. They use the idea of variables as boxes as the basis of a group activity, developing their use of logical thinking to trace variables through programs.

This unplugged activity from Peter McOwan and Paul Curzon mingles computer science with biology. A group activity is used that mimics the firing of neurons within the brain. These trigger other neurons to fire – these can be compared to AND gates in logic circuits.

The ‘brain in a bag’ kits used in the...

This activity from the Computer Science for Fun (CS4FN) team at QMUL is an introduction to algorithms suitable for those in upper primary school. A ‘self-working’ magic trick is shown – this is a trick that works every time, as long as the process is followed exactly. No understanding of the trick is needed by the...

This activity from the CS4FN team at QMUL is a metaphorical introduction to Human-Computer Interaction (HCI), graphical user interfaces (GUIs) and the difficulties of working at the command line.

The whole-class activity uses a game called spit-not-so. The winner of the game is the first to choose, from a...

Using a set of simple ‘swap puzzles’, this CS4FN activity helps students to learn, fundamentally, what an algorithm is and how they can be made more efficient. Students are encouraged to create algorithms for solving the puzzles which can be used by future players to win, with no understanding of the game, in as...

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...

In this activity from the CS4FN team, learners are introduced to algorithms in the context of artificial intelligence. They are challenged to beat a ‘piece of paper’ at a game of noughts and crosses. By following a simple algorithm, the piece of paper becomes very difficult to beat. The algorithm is a sequence of...
