ClassDojo is an online classroom management platform and app where teachers can record and track student behavior, facilitate classroom activities, curate student portfolios, and engage in school-to-home communication. Student sign-in is simple with a class code, QR code, or username. From the teacher dashboard, teachers can create original activities or use the toolkit to post class announcements, assign from the library, create random groups, and more. Depending on how they choose to set things up, teachers can share information privately or publicly, often displayed to the class on a screen or interactive whiteboard. It's possible to translate messages home into 30+ languages.Â
