When getting started on Code.org as a teacher, you'll first want to find the right course for your students to work through. From our courses page, you'll find this chart on what courses would be most applicable for a given grade or grade range.
We offer several shorter Hour of Code courses, and longer main courses which have accompanying curriculum and in-depth lesson plans. You can find all accompanying curriculum for all of our courses at curriculum.code.org. Once you've decided on a course for your students, you can create a class section for them to join, via student accounts you can make for them as well.
