Problem solving using programming constructs

Computing

Sequence

Program variables

Selection

Operators

Count-controlled iteration

In this unit pupils will build their confidence and knowledge of the key programming constructs (sequence, iteration, selection and variables). Learners will use Scratch to explore the key programming constructs firstly through editing pre-existing code and then by developing their own programs.
