Triventy is a excellent site for creating collaborative quizzes or surveys. The way this works is a user creates their own questions or customizes an existing one and then invites students to add their own. Once the quiz is started (up on a board, projector, screen etc.) a teacher can invite students via unique URL to join. Once the quiz is finished the participate get results in real-time similar to the way Kahoot works.
I highly recommend checking out Triventy by clicking here!!!
