Google Forms are a great way to give quizzes, collect exit tickets and assignments, and get feedback. Sample forms are attached for you to copy and use (Make sure to make a COPY of anything you want to use or modify)

There are multiple ways that Forms can enrich your lessons - you can use them to differentiate instruction through branching questions, check for understanding and get quick student feedback through quizzes, surveys, and exit tickets, and embed them into hyper docs and web quests to enrich a project or activity.

With the newest Google Classroom update (2018/19) you can create a Forms quiz directly from Classroom and import the grades into the Classroom assignment.
