Compact, silent timer clock with traffic light disc ... The clock running backwards shows analogously to the minute how much time is left until the task is completed. Green-yellow-red areas on the traffic light disc visualise the remaining time zones within the last 15 minutes of 7 + 5 + 3 minutes. After the time has expired, a signal tone sounds; duration and volume are adjustable. The display of the remaining time on a familiar clock face helps the students to take responsibility for dividing the time. The wide base ensures that the handy clock with protective glass stands absolutely securely. The time can be set with an easy-to-grip rotary knob. 2 x AAA battery required (not incl.). Material: synthetic material, metal Measurements: 7.8 x 7.8 x 4.5 cm
