Project 2: Functions
When to Do It
What to Do
Visit scratch.mit.edu and sign in to your account. Click the “Create” button to create a new project.
Your assignment is to create a Scratch animation. Your project should include:
- At least one Motion block.
- At least one Looks block.
- At least one Sound block.
Once finished with your project, select File > Save now one last time. Then select File > Save to your computer and keep that file (with file extension .sb3) so that you can submit it. If prompted by your computer to Open or Save the file, be sure to Save it.
How to Submit
Beginning 2024-01-01T00:00:00-05:00, the course has transitioned to a new submission platform. If you had not completed CS50 Scratch prior to that time, you must join the new course pursuant to Step 1, below, and also must resubmit all of your past projects using the new submission slugs to import their scores. We apologize for the inconvenience, but hope you feel that access to rapid grading, which is new for 2024, is a worthwhile trade-off for it, here!
This step assumes that you’ve downloaded your Scratch project as a file whose name ends in .sb3. And this step also assumes that you’ve signed up for a GitHub account, per the above form.
- Visit this link, log in with your GitHub account, and click Authorize cs50.
- Check the box indicating that you’d like to grant course staff access to your submissions, and click Join course.
- Go to submit.cs50.io/upload/cs50/problems/2024/scratch/functions.
- Click “Choose File” and choose your
.sb3file. Click Submit.
If you encounter the error “No files in this directory are expected by cs50/problems/2024/scratch/functions”, please make sure your scratch project file name indeed ends with .sb3!
That’s it! Once your submission uploads, you should be redirected to your submission page. Click the submission link and then the check50 link to see which requirements your project met. You are welcome to resubmit as many times as you’d like (before the deadline)! Note that if you upload a file whose size is larger than 10MB (which is quite large for a Scratch project) check50 may struggle to process it. Best to make sure your file is smaller than that limit.
