64 Python programming exercises ranging from “Hello World” style first programs to file reading and writing. Many tasks also have extension (“bonus”) sections to stretch pupils. Exercises are sorted into sections by the skills needed to complete them (conditionals, loops, arrays, etc). A good resource for homework, extension tasks, and independent learning. Fully editable resource, ready for printing or online use. Topics covered: Basic input and output Conditionals Loops (while and for) Strings Lists Subroutines and functions File reading and writing Some of the exercises in this document require sample code for students to edit: this code is provided in the download. The exercises in this resource can be completed in any programming language, but some of the phrasing in the questions is specific to Python. There is also a Java version of this resource available.

Two worksheets covering negative binary numbers in sign & magnitude and two’s complement representations. Each worksheet has a separate answer key. Fully editable resource.

Full lesson - Introduction to data representation and binary numbers. This lesson introduces the concept that everything in a computer is represented as binary, explains how binary works, and covers binary to denary conversion. Includes teacher’s PowerPoint, activities, and homework (with solutions). Fully editable resource.

Full lesson - Introduction to representing negative numbers in binary. This lesson recaps binary representation and then introduces negative numbers. To aid understanding of two’s complement, binary addition is also covered. Both sign and magnitude and two’s complement are covered, with worked examples, exercises, and an explanation of the problems with sign and magnitude notation. Includes teacher’s PowerPoint, activities, and homework (with solutions). Fully editable resource.

Practical lesson on low level languages, focusing on assembly language. The bulk of the lesson is practical programming exercises using the Little Man Computer (LMC). By comparing their existing knowledge of a high level language with these assembly language programming tasks, pupils should be able to grasp the differences between the two types of programming language. The plenary reinforces these differences. Includes a worked example, 6 differentiated assembly language program activities, an instruction set help sheet, a short lesson plenary, and a longer version that can be used as homework (both with answers). Fully editable resource.

Full lesson - Binary shifts. This lesson explains the concepts of logical and arithmetic binary shifts (left and right) with clear, full screen diagrams and examples. Practice questions and a full worksheet (with solutions) are included. Fully editable resource.

Full lesson - The Internet and WANs. This lesson builds on the previous introduction to networks and introduces the concept of WANs and the Internet backbone. It covers the implications that the Internet’s structure has for reliability and security. Includes starter activity, teacher’s PowerPoint, activities, and homework. Answers are provided for all activities and homework. Fully editable resource.

A fill-in-the-gaps activity for students to improve their understanding of computer system components. Students must complete the tree diagram, which includes hardware (input, output, storage, and processing) and software (application software and operating systems). Useful as a lesson plenary or an end of topic summary. Suitable for KS3 or GCSE Computer Science. Fully editable resource. Includes tree diagram with gaps and the solution.
