ClassDojo is a popular, free educational technology platform that connects primary school teachers, students and families to build classroom communities. It acts as a communication hub for sharing updates, photos, and videos, while allowing teachers to encourage positive behaviour and social-emotional skills through customizable points, avatars, and portfolios.

The "Class Story" feed allows teachers to share updates, photos, and videos with all parents, while a secure messaging system enables direct, two-way communication between teachers and families, including translation in 35+ languages.
