Home Teaching: Key Stage 5

This page is designed to help learners, to continue their computing studies while at home at any time including during the holidays.

Support is available

If you have any questions about the topic or any of the lesson resources you can contact us by emailing info@teachcomputing.org.


Object-oriented programming

The following resource links will take you to the FutureLearn website, all resources are free to access, but do require you to sign up for a free account with FutureLearn.

Although this course is described as being 4 weeks long on FutureLearn, weeks 3 and 4 have been split up for the purposes of Home Teaching.

Lesson 1

During lesson 1 you will learn how objects are used in OOP and how to write a program using an object.

Lesson 2

During lesson 2 you will develop your own object-oriented adventure game.

Lesson 3

During lesson 3 you learn how to extend a class using object-oriented programming.

Lesson 4

During lesson 4 you'll learn how to extend classes by introducing new characters into your game.

Lesson 5

During lesson 5 you'll learn the difference between class variables and instance variables.

Lesson 6

During lesson 6 you'll add the finishing touches to your game, and package it so that the classes you have written can be used by other people.


Number bases and algorithms
