GCSE Computer Science Pseudocode to Python Activity

GCSE Computer Science activity: 13 pseudocode tasks to predict, write in Python, run and check. From output to sorting and subroutines. Answers included.

A structured activity that helps students move from reading pseudocode to writing real Python programs. Ideal for linking algorithms and programming.

How it works
For each task, students:

1. Read the pseudocode and predict the output
2. Write the algorithm as a Python program
3. Run it and record the actual output, then compare it with their prediction

13 tasks that build in difficulty
Hello World, a greeting, adding two numbers, odd or even, counting to 10, times tables, a password check, guess the number, an average, reversing a string, linear search, bubble sort and subroutines.

What’s included

• Student activity sheet (editable Word document, A4 landscape)
• Answer sheet with example outputs and typed Python solutions in red, plus notes on alternative approaches

The pseudocode uses the AQA exam style (for example, ← for assignment), making it ideal for AQA 3.1 and 3.2, and useful practice for any GCSE board.
