Quizizz

Quizizz is similar to Kahoot but with the added bonus of being able to display the quiz questions directly on all student devices. It also has a large library of premade quizzes from teachers and students all around the world.

Quizizz also has an app is on all library iPads so theoretically, a class could borrow them so they all had an iPad in front of them and their laptops could be freed up (or put away) depending on need.
