Below is a collection of Google Sheets add-ons that I believe every teacher and educator should at least be aware of. These are tools that provide you with tons of functionality hacks to enhance your productivity and facilitate your workflow. Some of the things you can do with these add-ons include: creating forms of various types (e.g., quizzes, assignments, surveys, etc), generate PDFs and documents from Sheets’ data, grade and analyze digital assignments, create a class website from spreadsheets, and many more.
