Work with a partner to collaborate using GitHub. Both students should create GitHub accounts, which are free. Student A creates a repository and adds Student B as a collaborator. B pulls the repo, makes changes, and pushes them. A pulls B’s changes, makes some additional changes, and pushes them. B pulls again and sees A’s changes reflected.
