Kahoot is a new, free game based formative assessment tool for use in the classroom. The teacher can create quizzes, discussions or polls for students and they can use their computer, tablet or phones to join to answer the questions. Using the points system, more points are awarded the sooner someone answers correctly. This can replace lots of review activities and even formative assessments. There is rapid feedback to the teacher and the students and results can be downloaded after each quiz.
