If you wish to continue working in Scratch, you can go to scratch.mit.edu, click on Ideas, and choose any of the projects to work on. When you start:
1) As soon as you start the project, click on Share in the project.
2) Click on Add to Studio and add it to the Student Project Studio.
3) Click on Copy Link, copy the link, and then go to submit the project and add the link to the asssignment in Google Classroom and press turn in.
This way, I can see what you're doing and make suggestions and track your progress.
