Codecademy is a website that teaches you how to code. You can join for free and have access to what they label skill building or you can go Pro for $19.99 a month and chose a career path that will give you a more in depth line of courses. When you first sign up you can explore on your own or you can chose to be guided. when you are guided they will ask you four questions to get an idea of why you came to be on the website. The first question they ask is "What brought you here?". Then they ask "What topic are you interested in?", "What is your learning pace?", and "How do you plan on using Codecademy?". Once you have finished answering those questions you will be giving the courses that they feel like will best help you achieve your perceived goals by the answers that you have giving for the questionnaire. To keep it simple for a beginner you can start of with the course Welcome to Codecademy! This course will teach you how to code starting with the simplest codes. If you like the coding experience I would suggest going Pro. This could be very expensive for one classroom so I would suggest having your school pay for it.  Happy Coding!
