Data types
Data types decide what operations make sense. You can multiply an int, join a string and check a bool — mixing them without converting is where the errors live.

The big idea
This module re-establishes the fundamentals at a higher standard: correct data types, clean input and output, and code another person can actually read. Speed comes later — clarity comes now.
Why it matters
Class 7 work stacks quickly. Students who write readable code spend the rest of the year building; students who do not spend it hunting for their own mistakes.
Unpacked
What you will actually learn
Three core ideas, each taught with worked examples and then practised until it feels obvious.
Input and output
Good input and output means prompting clearly, validating what arrives, and formatting results so a human can read them at a glance. f-strings make this painless.
Readable code
Readable code means meaningful names, consistent spacing and short comments explaining why, not what. Your future self is the reader you are writing for.
Did you know?
Developers spend roughly ten times longer reading code than writing it. Every minute spent on a clear variable name pays itself back many times over.
Common mix-up
“Comments make code good.” Clear naming makes code good. Comments explain the reasoning that names cannot carry.
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 data types.
- 2
Data types
Guided teaching on data types, worked through together with the teacher.
- 3
Data types — practice lab
Independent practice, small challenges and one deliberate mistake to diagnose.
- 4
Input and output
Guided teaching on input and output, building directly on the previous two sessions.
- 5
Input and output — practice lab
Applied tasks that combine data types and input and output in one piece of work.
- 6
Readable code
Readable code introduced and practised, completing the toolkit needed for the project.
- 7
Project build
Guided build session for the module project: Profile generator.
- 8
Test, present and reflect
Finish, test against the checklist, present the work and explain the decisions behind it.
Project lab
Profile generator
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 any program you wrote last year and rename every variable to something honest. Do not change the logic — just the names — and see how much clearer it reads.
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 data types without prompting
- Explain and use input and output without prompting
- Explain and use readable code without prompting
- Build and finish profile generator
- 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:
- data type
- The kind of value a variable holds.
- f-string
- A Python string that can embed values directly.
- refactor
- To improve code structure without changing what it does.
