Kahoot is a fantastic resource. There is a slew of advantages.
1. If used at the beginning of a period, it is a way to get students prepared for that session
2. It can act as a calming exercise for a given topic. For example, if the class is preparing for a test, the introductory questions may be used for focus purposes.
3. Whether virtual or in-person, a student may anonymously answer if they are fearful of group activities.
4. It is a tool to help master knowledge retention
