KS3 Introduction to Python 6 lesson pack

This Introduction to Python: 6-Lesson Bundle takes students from absolute beginners to writing interactive, logical programs. Designed for Year 9 (KS3), the series transitions students from block-based logic to industry-standard text-based coding, focusing on syntax, data handling, and selection.

• Lesson 1: Hello Python – An introduction to the Python IDE and high-level languages. Students write their first scripts using the print() function and learn the difference between machine code and interpreted languages.
• Lesson 2: Storing Data – Introduces Variables as named locations in memory. Students practice assigning and updating values, using the “cardboard box” analogy to understand how data is stored and overwritten.
• Lesson 3: Inputs & Strings – Focuses on Interaction. Students learn to use the input() function to capture user data, join strings together using Concatenation, and use Comments (#) to document their code.
• Lesson 4: Numbers & Maths – Introduces Calculations and Casting. Students learn to convert string inputs into Integers or Floats to perform arithmetic operations, building tools like area calculators and age trackers.
• Lesson 5: Using Logic – The first step into Selection. Using the “Bouncer at the Club” analogy, students learn the syntax of if statements, the importance of Indentation, and the use of colons.
• Lesson 6: Comparing Data – The series finale covers Boolean Logic and Comparison Operators (>, <, ==, !=). Students expand their programs with else statements and build a functional “Score Checker” and “Number Guesser.”

###Key Features of this pack###

• Consistent Structure: Each lesson includes clear Learning Objectives, a “Starter” recall task, live coding demonstrations, and independent practical challenges.
• "Syntax Saboteurs": Integrated debugging tasks help students identify common errors like missing colons, case sensitivity, and indentation mistakes.
• Extension Challenges: Every lesson contains “Gold” level tasks to stretch high-ability students, such as using modulo operators or nested logic.
• Assessment Ready: The pack concludes with a plenary review of key vocabulary (Variables, Casting, Concatenation, Selection, Booleans) to prepare students for formal CS assessments.
