Game show buzzers let you turn any lesson into a game and get students actively engaged as you assess them. Four different colors and fun sounds include a horn honx, boxing bell, doorbell and boing sound. Buzzers also enable students to work on their own while allowing them to signal to a teacher when they need help. Buzzers require three AAA batteries and are designed for children ages 3 and up.
