Formative Assessments 

Ed Puzzle is a website where you can load in videos from a variety of sources (as well as your own).  You can insert questions into the video that the viewer has to answer.  There is a paid version, but you can do just about everything you want in the free version. 

Quizlet is a website where users can enter in a "study set", consisting of a "term" and a "definition". Quizlet then transforms that study set into a variety of study tools ranging from digital flashcards, to video game-like tasks... all accessible to your students via a single link.

Along with text based definitions, you can also insert pictures. Math and science teachers, this means you can have the "term" be a problem to solve, and the "definition" is the solution!

Once you have created a Quizlet study set, your student can play the Quizlet Live activity where they need to work together in teams to determine the correct "term" that matches a given "definition".

This activity can be played on any device (computer, laptop, chromebook, iOS  and/or Android device... all together. 

PollEverywhere is a web based polling platform that allows participants to respond via a website or via text messaging on their personal device.  PollEverywhere integrates with Google slides to allow you to post your polls directly from your slide deck. Alternatively, you can download your poll as a PowerPoint slide to insert in a pre-existing presentation.

Quizizz allows participants to answer multiple choice questions.  Both the questions AND answers appear on the participant's screen, so there is no need for a shared projection screen for participants. Participants are rewarded for answering correctly, and more points are given for faster responses.
