This presentation gives example code and show class diagrams. It teachers students about: Procedural Object-Oriented Declarative Students are also explained to and taught about: - Inheritance Polymorphism Constructors Inheritance Advantages

Many of my students struggled with the concept of converting from denary into floating point binary. This presentation shows a variety of question and breaks down how to tackle the questions. There are 5 sample questions at the end of the presentation for students to attempt and the technique is broken down into simple steps to help both the teacher and the students understand it. It breaks down how to do some simple questions such as number 7 but also shows you how to work out negative numbers such as -0.375 and shows the technique for multiplying the decimal by 2. I hope that this will help struggling teachers.

Break down of lessons including assessment : - Lesson break down included in the week plan so that you can see what students are expected to achieve. Topics covered in this unit of work: - -Connectivity -Hardware -IP address -Data Packets / Packet Switching -Hardware -Encryption -Topologies -Advantages / Disadvantages

This unit of work should break down planning techniques and give students a structure with some assessments to complete and assignment sheets to go with it. There are three assessment points. A timeline of what to complete and when as well as PowerPoint slides to go with each of the resources. This should give you some structure / guidance for delivering this in 2022.

This resource introduces the creation of a spreadsheet to users with multiple videos. There are 7 Powerpoints with some activities to complete. Over 12 video tutorials which include the following skills. There is a learning Journey document which shows what they should have learnt as well as a curriculum planning sheet for your faculty.
