Recap and recall
Before starting this unit, check the children can recall: Decomposition is breaking something down into smaller chunks. A code is a set of instructions that tell a computer what to do. Debugging is the process of fixing code when it does not work.

Adaptive teaching
Pupils needing support:
Should use the Activity: Carousel journal: support to help them log their findings during the carousel activity; could watch the Pupil video: Decomposition and the Pupil video: Pattern recognition before the lesson as a pre-teaching tool to build familiarity with the key concepts.
Pupils working at greater depth:
Should provide a detailed level of description in their journal explaining the link between the skill and the activity, e.g. using decomposition to break the journey into smaller steps in the Map it out activity; could design their own pattern or problem for others to solve.
