These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. The logical flow of a program is described step by step, showing the sequence of actions, decisions and outcomes.

Keywords

  • Decomposition - breaking down a problem into smaller parts to make the task more manageable

  • Flowchart - a visual representation of an algorithm or program

Common misconception

I can just start coding and figure it out as I go. Planning is a waste of time and boring.

Planning is like building a strong foundation. A good plan helps you write better code faster.
