A great introduction to understanding Moore’s law and how to convert between different memory sizes. This ready to use lesson will save you hours of preparation and can easily be adapted to meet your own requirements. WHAT IS INCLUDED? Everything you need is included such as: a very high-quality accessible PowerPoint presentation that effortlessly leads the teacher through the lesson and includes all the answers to the many questions and tasks the students need to complete a 2 sided editable worksheet an easy-to-follow editable lesson plan . PRIOR LEARNING This unit does not expect pupils to know about binary but most teachers use this after students have been introduced to the concepts of converting binary to denary. EASY TO USE These ready to use resources are so straightforward that although I have included a lesson plan, most teachers can teach straight from the PowerPoint presentation without any further assistance. And best of all, the answers are included saving you time and energy. This makes this lesson suitable for experienced computing specialist teachers along with non-specialists and early career teachers (ECTs). EDITABLE RESOURCES I understand that teachers want to adapt their resources, so I’ve made the bold decision to make these resources editable. Therefore, if you need to use a particular template style for your school, you can change the PowerPoint presentation, worksheet and lesson plan to suit your needs. If you have students with specific educational needs, you can change the lesson to suit them. It gives you the flexibility to alter the lessons to suit your own particular needs. SCIENTIFICALLY PROVEN TEACHING TECHNIQUES These teaching resources have been specifically designed to aid pupils using educational psychology backed theories to ensure your students will have a higher retention rate and a deeper understanding of the subject. TEACHING TO THE TOP This lesson is designed to stretch all pupils. Instead of traditional differentiation which systematically underchallenges pupils, I raise the bar for everyone and then, as a teacher who knows your own students best, you can support individuals to reach their own full potential.

Looking for some ready-made Python files to help your pupils learn about the bubble sort, insert sort, merge sort, linear search and binary search in more detail. Here they are. WHAT IS INCLUDED? In this unit you have 10 ready-to-use Python programs: 2 Bubble sort programs (one with comments and one without comments) 2 Insertion sort programs (one with comments and one without comments) 2 Merge sort programs (one with comments and one without comments) 2 Linear search programs (one with comments and one without comments) 2 Binary search programs (one with comments and one without comments) Not only that, but you also have 20 further editable handouts allowing you the flexibility to use these with either OCR, AQA and Edexcel exam boards.: 1 handout for each of the sorting and searching algorithms that includes the written algorithm and the flowchart. 3 editable handouts for each of the sorting and searching algorithms showing the pseudocode for either OCR, AQA or Edexcel . HOW CAN I USE THEM? You can use these ready-to-use Python programs and handouts in any number of ways. You could use these Python programs to show the code to the pupils and ask them how it works and talk through the code with them comparing it to the algorithm. You could challenge your students to add comments themselves to explain the code or use it to demo a working program. If you feel your pupils are able, you could set them the challenge of programming it themselves and use the completed programs as exemplar material to aid pupils who get stuck or even remove some of the code and ask them to complete key areas to make it work. You can give them the pseudocode and ask them to write the program from that. . PRIOR LEARNING This unit does expect pupils know what an algorithm is and be familiar with understanding written algorithms and flowcharts. It is also advantageous to have spent some time looking at each of the algorithms (bubble sort, insertion sort, merge sort, linear search and binary search) to only use these programs and handouts as an extension of earlier learning they have done with you to familiarise them with the algorithms and comparison of the algorithms. I have created a unit which includes 3 lessons that can be used to teach your classes about the algorithms. You can find out more about this unit here. #EDITABLE RESOURCES I understand that teachers want to adapt their resources, so I’ve made the bold decision to make these resources editable. Therefore, if you need to use a particular template style for your school or pupils with special educational needs, you can change the programs and handouts to suit your needs. Start reaping the benefits today of incredibly high-quality, professionally designed teaching resources that you can use with virtually no preparation.

Getting your classroom ready for back to school? Here is a fully editable PowerPoint presentation that contains 60 common computer science words and simple student-friendly definitions. They can be displayed as a permanent wall display or you can pick the words to display to compliment your current teaching goals. It is like having a computing dictionary on the walls of your classroom for the students to quickly refer to and can help with spellings of common computer science terminology as well as acting as a reminder of the meanings of computing terms. As it is fully editable you can add to and alter the definitions yourself to make a truly personalised learning wall display for your classes. These terms are suitable for KS3 computing and GCSE computer science classes. Each slide has been adjusted to print on A4 paper and it is recommended you print them in colour for maximum effect. The colours of the key terminology refer to the following categories: Blue – Programming and Algorithms Red – Networks Purple – Computer Systems Green – Cyber security Orange – Binary, Data and Logic

At the start of every term I get many emails and phone calls from teachers who have recently taken over as the head of Computer Science and are unsure where to start. Some of them are walking into a well-ordered department where everything is laid out and ready-to-go, others are not so lucky. Often, they are the only person in that department and so don’t have anywhere to turn to ask for help. And then the headteacher casually strolls into your room when you have barely been for a day and asks you for your ICT policy document by the end of the week. Gulp! Not to worry, I have this one ready to go and better still it is completely free! With a brief read through, only some minor tweaking to make it fit your school and copying them into your schools template it should satisfy your headteacher and give you a bit of valuable breathing space while you try to get your head around the one hundred and one other things you need to do. School Data Protection Policy A School Data Protection policy isn’t really your responsibility as head of computer science and is something somebody who has received adequate training should be looking after. The name of the allocated data protection officer (DPO) and their contact details should be inserted into section 5.2 (Data protection officer) and is usually somebody in the admin team.

A self-marking spreadsheet, you can install onto your computer network that the pupils copy into their own work area and work through. The stages get progressively harder and asks them to convert from binary to denary and from denary to binary. For some of the harder levels you may need to provide a piece of paper and a pen to help them work out the answers. Can even be used as a form of assessment as their work can be saved. Great to use either in the classroom or set it as a homework task. Suitable for GCSE Computer Science classes and KS3 Computing classes.
