This video is a sample of what you will see in the bank of 9 videos which will help your students get started with the Micro:bit. I hope this is useful and that the other videos will get your students started. This video shows you how to get a light moving left and right using iteration.

These video tutorials will help you deliver the MicroBit lessons and will also leave some of the tasks open ended. I have uploaded one of the videos for free so that you can see what they're like. The videos in this bank include: - * Spirit Level * Simple Maze Game * Simple LED Lights * Calculator - Add two numbers together using variables * Random number generator * Controlling how an LED moves around the screen * A + B buttons (selection) * How to make crossy roads on the screen * Iteration and moving lights All include some explanation of what has been taught and the key terms needed for programming. This has been done using the blockly editor.

This lesson gives you a structured break down to delivering the Micro:bit lesson for the first time. I have combined this with the Micro:bit book to make the creeper face. In this lesson: - * reason for the Micro:bit and discussion with the students * students given time to read health and safety instructions and feedback to the teacher * how to get onto the website. * pictures to show how to connect to the website * how to download the program in 3 easy steps * how to get the program onto the MicroBit * worksheet with extension * introduction to Selection * Challenge with video

Week 5 - Encryption Objective: - •To identify some of the data which should be kept secure from others. •To learn some of the ways in which data is kept secure. •To learn how unauthorised people can break ciphers and read encrypted data. •To learn about classical encryption techniques. ​Task 1 : - Come up with a list of data which would need to be kept secure. Task 2 : - Your teacher will print out this worksheet for you. They can click here to download it. You should use this file to help solve the message. Click here Task 3: - You are now going to learn a little bit about brute force and the Caesar shift. •https://vimeo.com/145990347 - Watch this video and find out more about the Caesar Shift. ​ Complete the worksheet using the PowerPoint's: - Click here

Topologies Presentation includes notes to train teachers who are very new to teaching computing. Week 3 - What is topology? Objective: - •Understand the difference between LANs and WANs •Be able to give examples of each network •Identify three different network topologies. ​ Task 1 : - Make notes about the difference between a WAN and a LAN network as your teacher explains things to you. This video will also be shown: - https://vimeo.com/145979347 Task 2: - Your teacher will now get you to act out 3 different networks by getting you up out of your seats. They will follow this by watching this video: https://vimeo.com/145982596 Task 3: - As a class you will come up with success criteria and produce a poster which meets the criteria. You should comment on the following:•​LAN VS WAN •STAR / RING / BUS ​ Useful links: •https://vimeo.com/145979347 - WAN / LAN video •https://vimeo.com/145982596 - Topology video

This scheme of work covers a wide range of topics on data representation and has an assessment at the end of it which uses previous exam questions over the years. It includes step by step help and teacher notes in the presentation. List of topics covered: - Lesson 1: - Students will also learn about: - Switches Binary Exam questions Binary conversion using switches Binary conversion using division Binary grid method Least / Most significant bit] Lesson 2: - Rules for adding using binary Showing how to add binary numbers Diagrams to help students Overflow information Explanation of what overflow is Worksheets How hexadecimal works Break down of how to convert into hexadecimal Lesson 3: - Character sets Exam questions worksheets Binary to ASCII conversion Explanation of ASCII and why 16 bit was need Break down of why character sets are needed Image conversion Images and pixels - how many bits Colour depth and formulas to work out file size Bits per pixel Meta data of images Lesson 4: - Analogue to digital compression Sample rate - number of samples taken when converting to digital. Bit rate - sample rate x bit depth Estimating file size Lossy and lossless compression: - When to use them Check Digits - Also diagrams to show you how to convert them. Written by Ray Chambers: - Pearson National Teaching Award winner 2015 - Innovative use of technology - Specialist in Computing

Objective: - We’re learning how to apply compression to sound and how to explain check digits. Students will be given a break down how sound is represented. The teacher will also have some teacher notes and things that they can talk about. I’ve included a worksheet for the end of this task which tests their knowledge of the PowerPoint slides. Where possible, I’ve tried to include a diagram to explain how it works so that it’s more visual for students. Keywords this lesson: Analogue Bit depth Bit rate Sample rate Compression Topics covered by this presentation: Analogue to digital compression Sample rate - number of samples taken when converting to digital. Bit rate - sample rate x bit depth Estimating file size Lossy and lossless compression: - When to use them Check Digits - Also diagrams to show you how to convert them. Content written by National Teaching Award winner: - Ray Chambers 2015 - Innovative use of technology.

Objective: - We’re learning how to use data to represent characters and images. Students will be given a worksheet to start this lesson which gets them to solve what the binary says. The answer is 'computing'. Once students have solved the question using a grid, it leads you into a conversation about how computers use binary to translate messages. There is a lot of theory in this but there is a worksheet to complete at the end of the lesson and there are two worksheets to complete throughout. Where possible there have been some hints and tips written in the notes. Covered in these slides: - Character sets Exam questions worksheets Binary to ASCII conversion Explanation of ASCII and why 16 bit was need Break down of why character sets are needed Image conversion Images and pixels - how many bits Colour depth and formulas to work out file size Bits per pixel Meta data of images This resource was written by award winning teacher, Ray Chambers: National Teaching Award winner 2015 - Innovative use of technology.

Objective: - We’re learning how to add binary and develop an understanding of hexadecimal. Students will be given a break down of how to add resources together. Where topics may have been a little tricky, I have included notes in the Powerpoint slides to help new teachers. I've tried to include hand drawn sketches in the presentation. This resource includes worksheets and answer sheets. There are two activities to complete and this lesson could take you across two lessons with the answer sheets and discussion. Covered in the slides: - Rules for adding using binary Showing how to add binary numbers Diagrams to help students Overflow information Explanation of what overflow is Worksheets How hexadecimal works Break down of how to convert into hexadecimal Content written by National Teaching Award winner: - Ray Chambers 2015 - Innovative use of technology.

Lesson explaining how Data representation works. There is a PowerPoint which walks through two methods of conversion but it also specifies how to use binary. It explains to students place value and compares denary to binary. Lesson 1 in a series of 4 lessons.
