I found this particularly interesting. Yes, there are all kinds of Scratch resources available if you take the time and effort to find them.
Unfortunately, so many of them are single activities that have been done so many times or they’re a cutesy little activity that has no beginning, middle, or end. They’re neat activities in themselves.
If you’re looking for a curriculum, a continuity, then these resources from the Canon Lab at the University of Chicago may be just what you’re looking for.
Scratch Act 1 is an introductory Scratch curriculum consisting of 4 modules, and about 10 hours of instruction. Module content is from SFUSD’s Green Workbook.
