This classroom-tested teaching aid reinforces the sense of elapsed time with a graphic depiction of the time remaining. As time elapses, the red disk disappears!
The new audible version features an optional sound to signal the end of a time segment. While teaching elapsed time, the Time Timer can also be used to set time limits, measure the duration of activities, and train students to make better use of available time.
8" is the most versatile size for both individual and group applications.
