Programming project: selection I
Lesson details
Learning outcome
I can design a solution to a problem that requires the use of selection.
Key learning points
- When approaching a programming project there will be a set of requirements that the program must solve or meet.
- When approaching a programming project it is useful to follow the software development life cycle.
- When designing a program it is useful to develop pseudocode before creating the actual program code.
Keywords
Pseudocode - a way of expressing an algorithm that is independent of a specific programming language
Software development cycle - defines the main stages of software development
Common misconception
Pseudocode is the same as a programming language and must follow a particular syntax.
Pseudocode is independent of a specific programming language and does not need to follow any particular rules. All that is required is that a programmer can read the pseudocode and understand how to implement it.
Teacher tip
This is the first lesson of two project lessons which can be used to give pupils the opportunity to apply their understanding of the programming concept selection. It would be advisible if pupils have covered selection before attempting this project.
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

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.
