Formative is a great tool to use as a quick formative assessment or exit ticket. It has a user-friendly interface and offers a variety of item types including typed response, true/false, multiple choice, and DRAW response. You can also insert images and blocks of text for students to read and respond to. The answers can be viewed live to give a quick check for understanding.
