Classes & Objects in Python OOP: Complete Teaching Bundle (Cambridge AS & A Level 9618, OCR A Level H446)

Teach object-oriented programming from the ground up. This ready-to-use bundle takes students from “what is a class?” to building programs made of interacting objects. It uses clear analogies, worked examples and exam-style questions.

Syllabus note: object-oriented programming is part of the Cambridge 9618 and OCR H446 A Level content. This pack focuses on classes and objects, the foundation for later work on inheritance and polymorphism. For Cambridge IGCSE 0478 and OCR GCSE it works as extension content only, as OOP is not required at that level.

What’s included

PowerPoint presentation: step-by-step explanations, worked code examples and diagrams linking classes to objects
Worksheet: graded tasks from reading a class definition to designing and writing your own
Hands-on activity: a practical task where students model a real-world scenario, such as a library, shop or game, using classes
MCQ quiz: quick questions for starters, plenaries or assessment
Full mark scheme: answers and explanations for every task, so marking is quick and consistent

Topics covered

Why programmers use OOP, compared with procedural programming
Classes as blueprints and objects as instances
Attributes (properties) and methods
The constructor: init and the role of self
Creating and using multiple objects
Encapsulation: public and private attributes, and getters and setters
Objects stored in lists and passed to functions
Class diagrams and linking Python code to exam-style pseudocode
Common errors, such as forgetting self and mixing up classes and objects

Why teachers like it

Zero prep: download and teach
Differentiated tasks that support all learners and stretch the more able
Real-world examples that make abstract ideas concrete
Fully editable
Works for lessons, homework, revision and NEA preparation

Suitable for

Teachers of Cambridge AS & A Level Computer Science (9618) and OCR A Level Computer Science (H446), and any programming course introducing OOP in Python. It can also be used as an extension for strong Cambridge IGCSE (0478) and OCR GCSE (J277) students.
