Use Playbuzz for Formative Quizzes

Playbuzz allows you to create  a variety of fun quizzes.

Here's one I created for the inventors and thinkers of the Industrial Revolution. It's called a "gallery quiz."

But you can also create quizzes using flip cards and you can create a poll or a ranked list.

Embed the quizzes in Blackboard or simply put the link in Classroom.
