Flippity https://www.flippity.net/ is a free resource that allows for the quick creation of quizzes, flash cards, presentations, memory games, word searches, and more. Flippity allows users to customize premade Google Sheet templates with their own content. Instructors can use Flippity as a presentation tool, or to create low- or no-stakes assignments through Google Sheets. Further, students can use Flippity to create their own projects. This resource can be used in face-to-face and online courses, at the individual, group, or whole class level.
This video: briefly describes how many of the templated activities available on the site work.
Flippity is not a plug-in to Google Sheets, so it does not require the creation of a username or password. As such, this tool is primarily recommended for creating activities aimed at engaging students in your course. Some of the activities can be downloaded as PDFs and distributed to students, in which case they could submit the activity via Canvas or in class.
