You do not have to do our courses in a particular order. Each course can be done during any year between first and fourth grade. Each course is designed so that you can complete it in one school year.
Each course stands on its own. Your student does not have to study one course in order to understand another. If you are switching to Notgrass History after using another curriculum, you can start with any of our courses.
