This Computing scheme of work video introduces Year 4 pupils to decomposition – a key computational thinking skill that supports pupils in breaking down complex problems into smaller, manageable parts. It shows how this approach can be used across a range of everyday and classroom tasks to build logical thinking step by step.

The video uses relatable examples to illustrate decomposition in action — from solving puzzles and organising daily routines, to tackling homework and cleaning a room. It then explores how the same strategy applies to computing, particularly in coding, where projects like designing a simple Scratch game become clearer and more achievable when broken into smaller stages.

This video is part of Kapow Primary’s Computing Computational thinking unit. It supports teachers in building pupils’ confidence with coding by showing how to simplify big challenges into smaller steps — helping them develop independence and problem-solving skills in lessons.
