Style and naming
Style and naming follow shared conventions — snake_case for variables, descriptive nouns for data, verbs for functions. Consistency is what makes code skimmable.

The big idea
This module raises the standard from working code to professional code — consistent naming, sensible structure, deliberate use of types and operators, and a repeatable routine for tracking down bugs.
Why it matters
Class 8 projects are large enough that sloppy code genuinely slows students down. Fixing habits now saves the whole year.
Unpacked
What you will actually learn
Three core ideas, each taught with worked examples and then practised until it feels obvious.
Types and operators
Types and operators deserve precision: integer division //, remainder %, and knowing when floating-point maths will surprise you.
Debugging workflow
A debugging workflow beats guessing: reproduce it, isolate it, print or inspect the values, fix one thing, re-test. Every step in order, every time.
Did you know?
In Python, 0.1 + 0.2 does not equal 0.3. It equals 0.30000000000000004 — a consequence of storing decimals in binary that affects every language, not just Python.
Common mix-up
“It runs, so it is finished.” Running is the minimum. Readable, testable and explainable is finished.
Session by session
Your 8-session journey
Sessions 1–8 of the 72-session year, at two one-hour sessions per week.
- 1
Warm-up and big picture
Where this module fits, what you will build, and a hands-on starter that gets everyone curious about style and naming.
- 2
Style and naming
Guided teaching on style and naming, worked through together with the teacher.
- 3
Style and naming — practice lab
Independent practice, small challenges and one deliberate mistake to diagnose.
- 4
Types and operators
Guided teaching on types and operators, building directly on the previous two sessions.
- 5
Types and operators — practice lab
Applied tasks that combine style and naming and types and operators in one piece of work.
- 6
Debugging workflow
Debugging workflow introduced and practised, completing the toolkit needed for the project.
- 7
Project build
Guided build session for the module project: Code quality makeover.
- 8
Test, present and reflect
Finish, test against the checklist, present the work and explain the decisions behind it.
Project lab
Code quality makeover
Every module ends with something the student built themselves and can demonstrate. This is the piece that goes into their portfolio and gets explained out loud at the end of session 8.
Try this at home
Take your longest program from Class 7 and rewrite it without changing behaviour. Compare line counts and clarity before and after.
It is finished when
- It works from start to finish without breaking
- You can explain every part of it in your own words
- You tested it and improved at least one thing afterwards
- Someone else used or understood it without your help
By the end of this module
Students finishing Module 1 can:
- Explain and use style and naming without prompting
- Explain and use types and operators without prompting
- Explain and use debugging workflow without prompting
- Build and finish code quality makeover
- Test your own work and correct what you find
- Talk an adult through what you made and why
Word bank
The vocabulary introduced here, in plain language:
- convention
- An agreed style rule shared across a language.
- floating point
- How computers store decimal numbers, approximately.
- code smell
- A sign that code, while working, needs restructuring.
