With the Unity Student Plan, Unity Collaborate enables learners to work on group projects with up to five teammates, manage versions, share work with teachers, and easily move between home and school computers. Learn how to set up Unity Collaborate here.
Another option is the GitHub for Unity extension, which integrates directly into the Unity Editor and enables students to easily configure, collaborate, and manage their projects in a dedicated window. Learn how to set up and use Git and GitHub with Unity here.
