Why this why now
Pupils continue to revisit core programming concepts to strengthen and deepen their understanding. This unit focuses on iteration, building on familiar ideas while introducing greater complexity in how loops are applied to solve problems. By refining their skills in structuring and controlling the flow of programs, pupils create code that is more efficient to code and more adaptable. This progression prepares them to tackle more sophisticated, real-world programming tasks with confidence and independence.
Prior knowledge requirements
- Pupils can write sequences in programs to solve a problem.
- Pupils can write selection in programs to solve a problem.
- Pupils understand how conditions are used to test the state of a program to use to control the flow of a program.
- Pupils can create variables in a program with an appropriate data type.

Programming: iteration
In this unit pupils discover how iteration is used to replicate parts of a program. They will analyse the difference between count and condition controlled iteration and how trace tables can be used to trace through loops. They will explore data validation techniques and robust program design.
