Hey, thanks for this!
I think my only issue with these sorts of timers--and maybe I just haven't learned how to use them properly yet!!-- is that it's very hard to adjust the times to suit your individual classroom-activity needs. So if I want to, for example, change the 2:00 minute mark to 5:00, it would take a long time because all of the numbers are literally stacked, one on top of the other, and would require still additional stacking if I wanted to go from 2 to 5!
Still, be that as it may, these timers are invaluable and save me lots of time!
Thanks again!
