Lesson 1: Invention design

Pupils choose an electronic product to design and then use and adapt existing code to achieve a desired result

Before the lesson

Learning objective

  • To design an electronic product

National curriculum

Pupils to be taught to:

  • Design, write and debug programs that accomplish specific goals, including controlling or simulating physical systems; solve problems by decomposing them into smaller parts.
  • Use sequence, selection, and repetition in programs; work with variables and various forms of input and output.
  • Use logical reasoning to explain how some simple algorithms work and to detect and correct errors in algorithms and programs.
  • Select, use and combine a variety of software (including internet services) on a range of digital devices to design and create a range of programs, systems and content that accomplish given goals, including collecting, analysing, evaluating and presenting data and information

Attention grabber

Main event


Pupils needing extra support: should be encouraged to use the existing code of a simple project and spend time finding out how it works and why and how they could make simple changes to it.


Pupils working at greater depth: should be encouraged to predict the code behind different projects before seeing how they work. You could also ask them how they would adapt the code to make changes to the product.
