Programming project: sequence I
Lesson details
Learning outcome
I can plan a program using a structured design and write code by following a clear, step-by-step sequence.
Key learning points
- 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.
Teacher tip
Use a "Code Planning Challenge." Give a problem, ask students code it, then plan it and compare results.
Equipment
Pupils will need access to a device that can edit and run Python programs. Examples in this lesson use the RPF Code Editor https://oak.link/python-editor
Licence

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
