• Socrative – It can be used on the fly, for quick quizzes, or for tests that count, and also works with competitive games like Space Race: http://www.socrative.com
• Kahoot – This program allows teachers to create quizzes, flashcards, and review games, with students using computers, cell phones, or other devices: https://getkahoot.com  
• Zaption – This tool can embed questions within a flipped video, not allowing students to continue till they’ve answered each one correctly: https://www.zaption.com
• Backchannel chat tools – These are live chats that accompany class discussions and allow teachers to create exit ticket activities. One example: http://www.chatzy.com
• Plickers – Each student holds up a unique QR card, with its orientation signaling their response to a 4-choice question, and the teacher’s smartphone reads and instantly tabulates individual and all-class responses: https://www.plickers.com.
