“The low-level software that supports a computer’s basic functions, such as scheduling tasks and controlling peripherals.” (dictionary definition) So, what is an Operating System - our computers, tablets, smartphones, etc all need one, but what do they actually do? The course is delivered in 4 x 60-minute lessons, using stimulating PowerPoint presentations with embedded videos, and includes worksheets to accompany the lesson, plus a Kahoot quiz. This series, for absolute beginners, looks at how computers worked before the Operating System the role of the Operating System managing things and user interfaces examples of Operating Systems Let me know if you have any questions or suggestions, and a BIG BIG thanks for looking (as a full time practising teacher, I KNOW how time consuming this process can be).Let me know if you have any questions or suggestions, and a BIG BIG thanks for looking (as a full time practising teacher, I KNOW how time consuming this process can be).

This is designed to support the Switched On Computing Year 4 unit 4.2, and has been specifically written with year 4 pupils in mind. My goal is to get students to create a fun project, whilst at the same time learn how the instructions work and fit together. To this end, I use the following approach: - break the project down into manageable chunks - present students with "pseudo-code" for each chunk - provide students with the Scratch commands to implement the pseudo-code, but jumbled up In this way, students learn about pseudo-code (an important part of coding), and have to understand the Scratch instructions in order to sequence them correctly to match the pseudo-code. The lessons comprise: 1. a PowerPoint with introductory slides and the project instructions 2. a Word document with the PowerPoint instruction slides printed 2 to a page as a handout 3. accompanying Scratch project files for teachers that match the project Other lessons in this series: A FREE introduction to Scratch. Project I: A maze type project. Project II: Create a question and answer type quiz. Project III: A game where students move a sight with the mouse to shoot ghosts. Project IV: Students create a Music Player with layers of menus for different categories. Project V: Simulate a toy with touch pads. Project VI: Drawing shapes and repeating patterns. Project VII: Base Attack. Project VIII: Flappy Octopus.</> Budle of Projects I-III. Budle of Projects IV-VI.

The Internet (or internet) is the global system of interconnected computer networks that uses the Internet protocol suite (TCP/IP) to communicate between networks and devices. The World Wide Web, commonly known as the Web, is an information system where documents and other web resources are identified by Uniform Resource Locators, which may be interlinked by hyperlinks, and are accessible over the Internet. (wikipedia definitions) This is a series of 60 minute lessons that will give students (and often, teachers) a much greater understanding of what the internet is, how it works and what the World Wide Web is (no, it is not the internet). Each lesson comprises: 1 a fully animated PowerPoint with explanatory slides 2 loads of embedded videos (can be extracted if required) 3 worksheets and self-evaluation files plus a Kahoot! Quiz The lesson objectives are: understand what the Internet is (also available as a FREE resource) understand how the Internet works understand what the World Wide Web is In addition, there are a series of lessons that look at what a web page is, how HTML works, and creating a web page using HTML ALL my postings are FULLY “classroom-tested” - before I publish, my lessons are tested by both myself and colleagues, rigorously evaluated and discussed, and continually updated to maximise their effectiveness.

Paint .NET is image and photo editing software that features an intuitive and innovative user interface with support for layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. My view…in the era of digital photography, every photo taken should be seen as a “draft” to be edited (or deleted!). These 3 lessons for absolute beginners look at what is paint .net and photo editing selecting and cropping colouring and recolouring image effects image adjustments correcting image exposure using curves and levels The lessons comprise: a fully animated PowerPoint with explanatory slides and tasks images files to match the tasks Let me know if you have any questions or suggestions, and a BIG BIG thanks for looking (as a full time practising teacher, I KNOW how time consuming this process can be).

Rock Paper Scissors provides the theme for this lesson on game playing, game designing and strategies. The lesson really brings this (hitherto) simple game to life and pushes it to the very limit. Children (and adults) love it! Driven by a PowerPoint full of illustrations and animations, and even links to videos (!), this lesson introduces children to the game, and then challenges them to play it as a class game in a very unusual and stimulating way. Even as an adult, I find this a real mental challenge, but great fun. Following on from this, there is analysis of the game, and opportunities to extend the game, devising rules and tables of outcomes.
