Watch It! Elapsed Time Clock™ by Educational Insights
The simplest, clearest way to teach elapsed time, this geared non-electronic set features two analog wristwatches with correlating digital clocks underneath. Move the minute hand on the first watch to your desired start time and the second to your finish time-the digital clocks underneath automatically adjust! Then slide open the cover on the answer window to see the elapsed time or keep it closed to quiz students. by Educational Insights
