ScratchCoding for Kids Scratch Welcome ●·4··················4·······4···························.·····4···4···44·····4····· A nyone can code. Certainly, writing the next Minecraft or programming complex simulations from scratch will require a deeper knowledge, but anyone and everyone has the potential to learn some basic coding skills then take those skills and write a simple program. This book can help you and your kids take that potential further. Read it, follow the projects and get to grips with the fundamentals of programming, and you and they can learn to code. We live in a world where technology and everyday life have never been more tightly interwoven, and that technology-the hardware websites and services we use all the time -is dependent on software. An understanding of how that software is made is as valuable in the 21st century as an understanding of engineering was in the 1oth and 2oth, and it's only going to grow more important. Forget all that stuff of grave importance, though or you may miss the fact that coding can be fun. You can make something in less than an hour, watch it work, then go back and make it better. As long as you have a computer-and almost any laptop or pc will do- you can build something brilliant bizarre or even useful, and the tools Stuart Andrews is a technology journalist specialising in PCs, games and business wont cost you a penny. Coding is creative. It pushes your imagination, your ability to and educational IT. He writes for a range improvise and your ability to plan of computing and technology magazines Most of all, it doesn't have to be difficult.

We also introduce SmallBASIC-a tablets Chromebooks and windows 8 PCs none of which have rubber keys.

By the time this book is over, we'll have started using Visual Basic, a tool that many professional programmers use every day.

When it comes to computing, code means -is the art of writing those instructions so This isn,'t one of those books that tells you all about a set of written instructions for a computer, that the computer can understand them programming but not how to do it. Nor is it one of usually arranged in a structure called a and the program functions as it should those books that gives you lots of code to type in rogram. When a user runs the program, It's also the art of arranging those but doesnt tell you how it works or what it's doing the code tells the computer what to show instructions so that the program works Instcad, wcre going to take you through a scrics on the screen how to process any data as smoothly and as quickly as it can of projects that will introduce the most important that the program uses, and what to do if and doing all this in a way that other concepts, help you use the key building blocks of certain things happen; for example if a programmers can follow if they need to code, and enable you to create fun programs that button is pressed.
