Kodu Lesson 2 : - Your world (KS2/KS3)

(0)
This lesson starts getting students to think about the way the world looks. Their main objectives are to learn how to create a basic landscape and to experience the techniques available. They will look at existing games and talk about what makes them more interesting. I've included some screen shots of existing games to guide the teacher. It starts getting the students to come up with a concept for their own game and they have a few ideas. Teacher requires prior knowledge of how to use the landscape tools or can use YouTube videos to support. Students to complete the worksheet to show that they're able to use the tools available and that they can come up with their idea. Homework included.

This lesson does require some prior knowledge of Kodu but it gives you structure to start delivering the curriculum and it will allow you to break down each lesson and to start teaching the students different items step by step. There are opportunities for students to think about what is needed for a game. There is a worksheet to help them to start thinking about what they're going to need to include in their own game. Once you've introduced this, teach the students how to create characters, worlds, objects and how to write a simple piece of code. Students are required to use the worksheet as they work through this PowerPoint with the teacher. This is a sample lesson to get you started and can be used for KS2 or KS3.

Microbit Lesson 2 - Magic 8 Ball

(0)
This Micro:bit lesson introduces to students how they can build a magic 8 ball using the microbit. Before they start building a magic 8 ball, students are introduced to how to use the A + B buttons and they're introduced to how to build a flow chart. They complete a simple cup of tea. Once they've complete a flow chart they will attempt to create one for a simple A + B program. After this they will work on a magic 8 ball. There is a video included which shows you how to do the random number generator for the magic 8 ball. This should give students the basic skills that they need for planning and it includes videos which will help them understand it.

Connectivity This lesson introduces students to how we connect to the internet and introduces them to terms such as I.P address and explains what happens with traffic. They're introduced to the number of devices which are available and have to do some independent research. They're also given the opportunity to set up a blog in which they can share all of their work their teachers. If you're un-happy for your students to blog, you could always keep a progress log. The blog was used as an e-safety tool and the teacher was able to explain how to post responsibly during lessons. •Week 2 - What is connectivity Objective: - •Learn the meaning and significance of bandwidth •Understand what is meant by buffering Task 1 : - www.submarinecablemap.com/ 1.There are a number of countries which only have 1 cable connecting them to the remainder of the world.

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.
