Lesson 5: Dismantling a tablet

Building on their understanding of computer parts from Lesson 2, children compare the similarities and differences between different types of computers before drawing a diagram of a tablet with all of its components

Before the lesson

Learning objective

  • To decompose a tablet computer

National curriculum

Pupils should 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

Success criteria

Cross-curricular links

Attention grabber

Main event


Pupils needing extra support: May benefit from a word bank of key terms and the Link: ‘Simon Haughton – Identify computer components’ for easier recognition.


Pupils working at greater depth: Should explain what the parts do and why they are important.
