Our ClassTimer is designed to help teachers transform their classrooms into amazingly productive environments by assisting students with time management. ClassTimer helps students visualize time and understand it as fundamental concept that needs to be managed in order to be more productive. Good time management leads to success in school and work. In addition to the digital time display, ClassTimer includes a bar graph style display so that young children can visualize the time remaining for a particular task. Using ClassTimer children can better understand when the next phase of the school day will begin or when the time allotted for a task will end. Students at all levels can benefit from better time management skills. Whether they are taking a standardized test, working in a small group on a project or involved in a form of creative expression, they will be better able to succeed if they properly manage the available time. The ClassTimer makes it easy to visualize the passage of time. Several options increase its usefulness. Selectable buzzer sounds signal that the allotted time period has come to an end. Sound can be turned on or off. Usually classroom teachers will use the minutes and seconds display (MM:SS), but in some cases may want to switch to the hours and minutes display (HH:MM). ClassTimer Features ClassTimer has several useful features. In addtion to the very large display, a bar graph style indicator shows the remaining time as a percentage.
