To be able to convert binary into denary and vice versa. Explain how characters are stored in the ASCII character set. Your students will learn this information through a variety of clearly presented instructions as well as a range of tasks and activities designed to consolidate learning. This unit of work also includes a final assessment. Full teacher solutions also included! Before completing this unit of work, it is recommended that your students complete Computer systems for year 7 so they have an understanding of the different hardware components of a computer.

Wrap your students minds around my latest poster collection, ideal as a revision tool to support all GCSE Computing courses! Todays World is full of online information and data, but how much is there? How much are we able to store now? What does the future hold? What is a bit? What is a Megabyte? How big is a Petabyte? A series of 12 informative posters on base 2 memory storage that begin at bits, nibbles & bytes then continues through to the mind blowing number of a Yottabyte! The posters include real world examples to help students comprehend what the numbers really mean! I have provided the posters as both a collection of JPEG files and in PDF format. Update: now in high resolution 2560x1440 ** Please leave a review!!! **

Introduction to computer systems for Year 7 students. The aim of this unit of work is to introduce year 7 students to the basic concepts of computer systems. What are we learning? To show understanding of the difference between input and output devices with suitable examples. To understand the difference between internal and external devices with suitable examples. To describe the different types of storage: Magnetic, Optical and Solid State. To understand the role and purpose of the CPU and the relationship with RAM (Fetch-Execute Cycle). To show an understanding of an embedded system including suitable examples. This unit of work includes a range of information and activities to develop student knowledge and understanding of computer systems. A final assessment is also included.

Teach your students how to use Excel through Dino Park! Students have been given a budget of £100,000,000 to build their park. They need to consider what dinosaurs they want to buy, how much space they will need, what facilities they require, staffing costs and ticket price. Excel Dino Park teaches you how to use functions and formulas through a series of engaging and interactive tasks which are differentiated to support a range of abilities. Skill that you will learn include: Add Raw data Create a graph Title a graph Formatting data Make arithmetic calculations using Excel Data validation (Drop down menus) Lookup formulas Use cell referencing in formulas Format graphs Cross worksheet referencing Advanced arithmetic calculations (nested) Use absolutely relative cell referencing Adding messages to data validation Efficient calculations (autosum) Conditional formatting Advanced graph formatting IF formulas Linking IF formulas and conditional formatting The clear explanations and step by step nature make it ideal for KS3 classes, but it is also suitable for ECDL, GCSE and beyond! Use alongside RobbotResources’ How2Excel’ workbook for a comprehensive understanding of how confidently use Excel! ************************Please leave a review!*************************

Revision clocks are a great way for students to develop retrieval practice in preperation for exam season! My students loved it and really engaged with it! This resource contains two revision clocks for both paper 1 and paper 2 topics for the AQA GCSE Computer Science specification as well as instructions to support their use. Note: it is recommended that the posters are printed out on A3 paper for best effect.

A simple poster to help explain the four concepts of Computational Thinking: Decomposition, Pattern Recognition, Abstraction and Algorithm Design! Computational Thinking is a skill set that can be used across the curriculum, not just within computer science! The logical approach to solving a problem means that it’s application can be used to develop and improve students ability to deal with difficult problems in a more rational way. The aim of my posters is to make you realise that many of the brilliant tasks that teachers facilitate week in, week out actually include computational thinking. It’s just a matter of making it more explicit!

The following quiz is based upon the four parts of Computational Thinking: Decomposition, Abstraction, Pattern Recognition and Algorithm Design. The quiz includes 8 questions including definitions and scenarios to test your students understanding of Computational Thinking. Ideal to use as either a starter or plenary! Give students a mini white board and marker pen for instant feedback! Also includes a Computational Thinking Recap slide prior to the quiz itself. Please leave a review!
