The hourglass tool allows you to set a timer from anywhere between one to sixty minutes. As time passes, the sand actually moves through the hourglass, giving students a quick idea of how much time they have left to complete a presentation or assignment.
The amount of time that the hourglass counts off can be changed in the settings by clicking on the hourglass and selecting the gear icon on the bottom left. When time is up, the tool will make a sound. You can change this sound in the settings as well or choose to play no sound if you’d prefer. You can pause, play, and reset the timer using the buttons under the hourglass.
