This lesson is a stand alone lesson that introduces students to the concept of hexadecimal and asks them to develop skills in converting between binary and denary and hexadecimal. Students will require knowledge of and skills with converting between binary and denary. It also starts to introduce the idea of colour and images being represented by computer code. It touches on high and low level programming languages. Learning Mat (LM) Worksheet is supplied as PPT, PPTX and PDF formats. Lesson Plan (LP) is supplied as PPT, PPTX and PPT Slideshow. Note that PPT files may lose some functionality.

This lesson is the 4th in a series of lessons designed to improve students’ understanding of how networks are organised. In this lesson students develop their understanding of key vocabulary such as IP addresses and the role of the router in transferring data between computers. It involves recall of key information from lesson 2 in the unit. Students are asked to describe the handshake process, discuss the format of data packets, and consider possible errors in transmission of data. This lesson is provided in PPTX, PPTS, PPT formats. The learning mat is provided in PPTX, PPT and PDF formats. Some animation and image features may be lost in PPT formats. A homework task is also included in this lesson.

This is the second in a sequence of lessons that introduce students to the principles of network organisation and the reasons why networks are used. This lesson looks at the differences between LAN and WAN, introduces the idea of a PAN, and also considers the role of the router in creating a LAN. The lesson plan is provided in PPTX, PPTS and PPT format, although some image and animation settings lose functionality in the older version of PowerPoint. The learning mat (worksheet) is also available as a PDF version. This will print on A3 paper.

This lesson draws the whole unit to a close. During the unit students will have studied the different hardware and software components that make up a computer system. You should use one lesson to set the assessment task and then use this lesson as an opportunity for Dedicated Improvement and Reflection Time (DIRT). Students will understand the correct answers to the questions on the assessment, and then complete 3 targets set by the teacher in their feedback. The lesson plan is provided in .PPT, .PPTS and .PPTX format, while the learning mat or assessment sheet is provided as PPTX, PPS and PDF.

This lesson builds on learning from the introductory lesson for this unit. In the previous lesson, students were asked to complete a homework research activity, so if you have not run this lesson you will need to delete or change this activity. The content of this lesson is a core part of the learning for the GCSE computer science course and asks students to understand that while the computer is running a program, the data and instructions need to be stored / held. You can extend students to understand that this disappears when the program stops or the computer is switched off. This lesson has been created with the Pearson Edexcel specification in mind, but is appropriate for other exam boards. Lesson plans are provided in PPTX, PPT and PPS format, while learning mats are provided in PPTX, PPT and PDF formats.

This lesson is the fifth in a sequence of lessons and looks at processor performance when related to clock speed, number of cores and bus speed. There are a variety of activities, but the main demonstrate phase considers the language of exams and helps students to understand how much to write in exam style questions. The learning mat (worksheet) is provided in PPTX, PPT and PDF formats. The lesson plan is provided in PPTX, PPTS, PPT formats, though the user should note that some animation and image features lose some functionality in PPT format.

This is a busy lesson and is fourth in a sequence of lessons that consider how computer systems integrate hardware and software. In this lesson, students consider what happens in the CPU during the fetch-decode-execute process. This lesson may need to be differentiated for some classes. There is an opportunity to consider how the registers work using the little man computer model using an online model. The lesson plan is provided in PPTX, PPTS and PPT format although some functionality (such as the video screen grab) is lost in PPT format so the screen grab is also provided separately. The worksheet (learning mat) is provided in PPTX, PPT and PDF formats.

This lesson is the 11th in a sequence of lessons that looks at how hardware and software are integrated on a computer system. This lesson looks at the differences between high and low level programming languages that can be used to create software. The lesson plan is provided in PPTX, PPTS and PPT formats, while the learning mat is available as PDF, PPTX and PPT files. Learning objective: Understand the characteristics and purposes of high and low level programming languages.

This is the first lesson in a sequence of lessons about modern use of technology. Students will be introduced to the terms ad hoc network and open Wi-Fi. They will be asked to describe some of the issues with open networks and compare a range of scenarios that may affect network availability. The lesson plan (LP) and learning mat (LM) are available as PPTX, PPT and PDF formats to ensure compatibility. Note that some animation features may not be available in PPT format.
