Google has a useful online platform loaded with free training and lessons for students and teachers. It's called Applied Digital Skills.
It offers a wealth of ready-to-go, project-based, asynchronous Google lesson plans that are free for anyone to use.
Example lessons are positive environment, getting digitally organized, and project based assignments using google tools/platforms.
