Google Workspace is a collection of online tools that allow teachers and students to work and collaborate online.
Google Classroom is the hub that enables communication between teachers and students. Each classroom has a feed for teachers to send messages and students to ask questions. Assignments are also set so students have their homework and all the materials they need in one place.
Google Drive is where all files are stored securely online. Drive allows students to access all their files in school and at home and there are no limits in storage space.
