Nearpod is a tool that allows teachers to create interactive presentations, quizzes, and activities that can be shared synchronously with students or assigned as homework. Teachers can add content like slides, videos, and audio, as well as activities such as open-ended questions, polls, quizzes, and drawing assignments. Students access the presentations using a pin number, and their devices become synchronized with the teacher's device. Students can then participate in interactive activities like taking quizzes, answering questions, and participating in polls on their devices.
