Why this why now

This unit reintroduces block-based programming to establish a shared foundation, allowing teachers to identify and address gaps in knowledge. It reinforces the key programming constructs: sequence, variables, selection, and count-controlled iteration. By securing these essentials now, pupils are better prepared for more complex programming in future units, including the transition from block-based to text-based languages later in KS3.

Prior knowledge requirements

  • Pupils should have experience of writing programs using block-based languages that use sequence, selection and iteration..
  • Pupils should be able to explain how algorithms describe the solution to problems.
  • Pupils should have experience of using events in programs as triggers to perform appropriate actions.

Using fundamental programming constructs in a block-based language

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.
