Unplugged coding games for children

How to practise algorithms, sequences, conditions, and debugging with paper, pieces, and movement.

Programming begins with organising clear instructions. Children can understand sequences, loops, and errors without a device by playing games in which another person carries out exactly the commands they receive.

The literal robot

One child gives instructions to guide a “robot” to an object: one step forward, turn right, raise a hand. The robot does not guess the intended meaning. When an instruction is ambiguous, the group rewrites it more precisely.

Patterns and loops

Build a repeated sequence of movements or colours. Instead of writing every step, invent a command such as “repeat four times.” Children see how a loop shortens an algorithm.

Debugging is normal

If the route misses its destination, the algorithm is not treated as a failure. Run it slowly, find the first step that differs from the intention, and change only that part. This attitude is useful in many kinds of problem solving.

A practical activity to try at home

  1. Draw a grid with obstacles and choose a start and destination.
  2. Write an algorithm with arrows, turns, and one repeat command.
  3. Ask another player to execute it exactly, then correct the first error together.

Unplugged games make the essential ideas of programming visible and show that errors are a normal part of building a solution.
