Python Parsons Problems – Beginner Coding Logic Worksheets (KS3, Ages 11–14)

Python Parsons Problems – Beginner Coding Logic Worksheets (KS3)

Build student confidence in Python with this beginner-friendly Parsons Problems activity pack, designed to introduce core programming concepts without overwhelming learners.

Ideal for KS3 (ages 11–14), this resource supports both experienced Computer Science teachers and non-specialists by shifting the focus away from syntax errors and towards logic, sequencing, and structured thinking. It provides a supportive, evidence-based approach to early algorithm design that fits seamlessly into any KS3 scheme of work.

What is a Parsons Problem?
A Parsons Problem is a scaffolded programming activity where students are given all the correct lines of code needed to solve a problem, but in a jumbled order.

Instead of writing code from scratch, students are challenged to:
• Sequence the logic by arranging the code lines in the correct order
• Apply correct indentation, reinforcing Python’s block structure

This approach reduces cognitive overload while still developing genuine programming understanding.

What’s Included in This Pack?
This 7-page printable PDF contains 5 low-difficulty Python challenges, carefully designed for beginners and early KS3 learners:

Problem 1: Count to Ten
(for loops, basic output)

Problem 2: Even or Odd
(modulus operator %, if/else selection)

Problem 3: Name Greeting
(user input, simple output)

Problem 4: Total a List
(lists, accumulation, for loops)

Problem 5: Password Check
(string comparison, selection)

All problems use centred, unindented code, so students must work out both the order and the indentation themselves.
