KAHOOT

Kahoot is a fun quiz-based learning platform which I really enjoy using. You can create quizzes on any subject and invite your students with a code. You essentially show the quiz questions on one screen while the students see the answer buttons on their individual screens simultaneously. The best with the highest speed wins. You can see your students' scores one by one and see what they need to work on without actually making them take a boring test. It also works with Zoom, MS Teams, Google Hangouts etc.

You can see a video below where Kahoot is used in a Zoom class.
