This creative teacher aid includes a Hot Dots Power Pen and comes with 300 cold — or wrong answer — dots, and 150 hot — or correct answer — dots that can be used to create any number of tests or quizzes. When the pen touches a cold dot, it makes a “boing” sound, and when it touches a hot dot, it responds instantly with lights and any of four positive reward sounds. Hot Dots provide immediate feedback, turning practice sessions into fun time.
